'''Constantine II''' ({{langx|el|Κωνσταντίνος Βʹ|Konstantínos II}}, {{IPA|el|ˌkonsta(n)ˈdinos o ˈðefteros|pron}}; 2 June 1940 – 10 January 2023)<ref>{{cite news|url=https://www.kathimerini.gr/society/562216114/pethane-o-teos-vasilias-konstantinos/| title=Πέθανε ο τέως βασιλιάς Κωνσταντίνος|website=Kathimerini|date=10 January 2023|access-date=10 January 2023|archive-date=11 January 2023|archive-url=https://web.archive.org/web/20230111100952/https://www.kathimerini.gr/society/562216114/pethane-o-teos-vasilias-konstantinos/|url-status=live}}</ref> was the last [[King of Greece]], reigning from 6 March 1964 until the abolition of the [[Greek monarchy]] on 1 June 1973.

Constantine was born in [[Athens]] as the only son of [[Paul of Greece|Crown Prince Paul]] and [[Crown Princess Frederica of Greece]]. Being of Danish descent, he was also born as a [[prince of Denmark]]. As his family was forced into exile during the [[Second World War]], he spent the first years of his childhood in [[Kingdom of Egypt|Egypt]] and [[Union of South Africa|South Africa]]. He returned to Greece with his family in 1946 during the [[Greek Civil War]]. After Constantine's uncle, [[George II of Greece|George II]], died in 1947, Paul became the new king and Constantine the [[Crown Prince of Greece|crown prince]]. As a young man, Constantine was a competitive [[yachting|sailor]] and Olympian, winning a [[Olympic medal|gold medal]] in the [[1960 Rome Olympics]] in [[Sailing at the 1960 Summer Olympics – Dragon|the Dragon class]] along with [[Odysseus Eskitzoglou]] and [[Georgios Zaimis|George Zaimis]] in the yacht ''Nireus''. From 1964, he served on the [[International Olympic Committee]].

Constantine acceded as king following his father's death in 1964. Later that year, he married [[Princess Anne-Marie of Denmark]], with whom he had five children. Although the accession of the young monarch was initially regarded auspiciously, his reign saw political instability that culminated in the [[Greek junta|Colonels' Coup of 21 April 1967]]. The coup left Constantine, as [[head of state]], with little room to manoeuvre since he had no loyal military forces on which to rely. He thus reluctantly agreed to inaugurate the junta, on the condition that it be made up largely of civilian ministers. On 13 December 1967, Constantine was forced to flee the country, following an unsuccessful countercoup against the junta.

Constantine formally remained Greece's head of state in exile until the junta abolished the monarchy in June 1973, a decision ratified via a [[1973 Greek republic referendum|referendum in July]], which was contested by Constantine. After the [[metapolitefsi|restoration of democracy]] a year later, [[1974 Greek republic referendum|another referendum]] was called for December 1974, but Constantine was not allowed to return to Greece to campaign. The referendum confirmed by a majority of almost 70% the abolition of the monarchy and the establishment of the [[Third Hellenic Republic]]. Constantine accepted the verdict of the 1974 vote.<ref>{{cite news | url=https://www.ft.com/content/5abf4fe0-04b0-11e1-91d9-00144feabdc0 | title=Referendum plan faces hurdles | last=Hope | first=Kevin | website=[[Financial Times]] | date=November 2011 | access-date=19 November 2020 | archive-date=6 January 2012 | archive-url=https://web.archive.org/web/20120106022323/http://www.ft.com/cms/s/0/5abf4fe0-04b0-11e1-91d9-00144feabdc0.html | url-status=live }}</ref><ref>{{Citation|title=Constantine II|encyclopedia=Encyclopædia Britannica Online Academic Edition|year=2011|access-date=12 November 2011|url=https://www.britannica.com/EBchecked/topic/133931/Constantine-II|quote=On 1 June 1973, the military regime ruling Greece proclaimed a republic and abolished the Greek monarchy. A referendum on July 29, 1973, confirmed these actions. After the election of a civilian government in November 1974, another referendum on the monarchy was conducted on 8 December. The monarchy was rejected, and Constantine, who had protested the vote of 1973, accepted the result.|archive-date=1 December 2011|archive-url=https://web.archive.org/web/20111201212205/https://www.britannica.com/EBchecked/topic/133931/Constantine-II|url-status=live}}</ref> From 1975 until 1978 he was involved in conspiracies to overthrow the government via a [[coup]], which eventually did not materialize. After living for several decades in London, Constantine moved back to Athens in 2013. [[Death and funeral of Constantine II of Greece|He died]] there in 2023 following a stroke.

==Early life==
{{stack|float=left|[[File:Paul and Frederica of Greece.jpg|thumb|left|Constantine's parents, Frederica and Paul, in 1939]]}}
Constantine was born in the afternoon of 2 June 1940 at his parents' residence, [[Villa Psychiko]] at Leoforos Diamantidou 14 in [[Psychiko]], an affluent suburb of [[Athens metropolitan area|Athens]].<ref>{{cite book | author=Meletis Meletopoulos | title="Κωνσταντίνος Β΄",Η βασιλεία στη Νεώτερη Ελληνική Ιστορία.

His father was the younger brother and [[heir presumptive]] of the reigning [[Greek king]], [[George II of Greece|George II]], and his mother was the only daughter of [[Ernest Augustus, Duke of Brunswick]], and [[Princess Victoria Louise of Prussia]].<ref name=Burke>{{cite book|editor-last=Montgomery-Massingberd|editor-first=Hugh|editor-link=Hugh Massingberd|title=Burke's Royal Families of the World|volume=1: Europe & Latin America|location=London|publisher=[[Burke's Peerage Ltd]]|year=1977|isbn=0-85011-023-8|pages=327–28}}</ref><ref name="waiting">{{cite book | author=Curley, W.J.P. | title=Monarchs In Waiting| location=London |publisher=Hutchinson & Co Ltd | year=1975 | isbn=0-09-122310-5 |pages=39–41}}</ref>

Prince Constantine had an elder sister, [[Queen Sofía of Spain|Princess Sofia]], born in 1938.<ref name=Burke/> However, since [[agnatic primogeniture]] governed the succession to throne in Greece at the time, the birth of a male [[heir to the throne]] had been anxiously awaited by the [[Greek royal family]], and the newborn prince was therefore received with joy by his parents.{{sfn|Tantzos|1990|p=5}}{{sfn|Mateos Sáinz de Medrano|2004|p=110-111}} His birth was celebrated with a 101–[[gun salute]] from [[Mount Lycabettus]] in Athens, which, according to tradition, announced that the newborn was a boy.<ref>{{cite news|title=Νεόλογος Πατρών|newspaper=Νεόλογος Πατρών|issue=132|date=4 June 1940|lang=el}}</ref> According to [[Greek naming practices]], being the first son, he was named after his paternal grandfather, [[Constantine I of Greece|Constantine I]], who had died in 1923.<ref>"Naming practices" in British Academy and Oxford University, ''Lexicon of Greek Personal Names'', [http://www.lgpn.ox.ac.uk/names/practices.html online] {{Webarchive|url=https://web.archive.org/web/20180816211449/http://www.lgpn.ox.ac.uk/names/practices.html |date=16 August 2018 }}</ref> At his [[baptism]] on 20 July 1940 at the [[Royal Palace of Athens]], the [[Hellenic Armed Forces]] acted as his godparent.{{sfn|Mateos Sáinz de Medrano|2004|p=367}}<ref>{{Cite book|first=Monique|last=da Rocha Carneiro|title=La descendance de Frédéric-Eugène duc de Wurtemberg|location=Paris|publisher=Éditions L'intermédiaire des chercheurs et curieux|year=2000|page=411|isbn=978-2-908003-17-8|language=fr}}</ref>

===World War II and the exile of the royal family===
Constantine was born during the early stages of [[World War II]]. He was just a few months old when, on 28 October 1940, [[Fascist Italy]] invaded Greece from [[Italian protectorate of Albania (1939–1943)|Albania]], beginning the [[Greco-Italian War]]. The [[Greek Army]] was able to halt the invasion temporarily and push the Italians back into [[Albanian Kingdom (1939–43)|Albania]].{{sfn|Van der Kiste|1994|p=159 and 161–162}}{{sfn|Hourmouzios|1972|p=116}}{{sfn|Tantzos|1990|p=15-16}} However, the Greek successes forced [[Nazi Germany]] to intervene and the Germans [[Battle of Greece|invaded Greece]] and [[Invasion of Yugoslavia|Yugoslavia]] on 6 April 1941 and overran both countries within a month, despite British aid to Greece in the form of an expeditionary corps.{{sfn|Van der Kiste|1994|p=162-163}}{{sfn|Palmer|Greece|1990|p=80}} On 22 April 1941, Princess Frederica and her two children, Sofia and Constantine, were evacuated to [[Crete]] in a British [[Short Sunderland]] [[flying boat]] along with most of the Greek royal family. The next day, they were followed by King George II and Prince Paul. However the imminent [[German invasion of Crete]] quickly made the situation untenable and Constantine and his family were evacuated from Crete to [[Kingdom of Egypt|Egypt]] on 30 April 1941, a fortnight before the German attack on the island.{{sfn|Tantzos|1990|p=18-20}} In [[Alexandria]], the exiled Greek royals were welcomed by the Greek diaspora, which provided them with lodging, money and clothing.{{sfn|Mateos Sáinz de Medrano|2004|p=113}} The presence of the Greek royal family and government began to worry [[King Farouk of Egypt]] and his pro-Italian ministers. Constantine and his family, therefore, had to seek another refuge where they could get through the war and continue their fight against the Axis powers. [[George VI of the United Kingdom]] opposed the presence of Princess Frederica, who was suspected of having Nazi sympathies,<ref>{{Cite web|url=https://www.britannica.com/biography/Frederica-queen-of-Greece|title=Frederica, queen of Greece|website=[[Encyclopedia Britannica]]|date=14 April 2023 }}</ref> and her children in Britain, but it was decided that Constantine's father and uncle could take up residence in London, where a government-in-exile was set up, while the rest of the family could seek refuge in the then-[[Union of South Africa]].{{sfn|Vickers|2000|p=292}}{{sfn|Van der Kiste|1994|p=164}}

On 27 June 1941, most of the Greek royal family, therefore, set off for South Africa on board the Dutch steamship ''Nieuw Amsterdam'', which arrived in [[Durban]] on 8 July 1941.{{sfn|Mateos Sáinz de Medrano|2004|p=113}}{{sfn|Bertin|1982|p=338}}{{sfn|Tantzos|1990|p=20-21}} After a two-month stay in Durban, Prince Paul left for England with his brother, and Constantine then barely saw his father again for the next three years.{{sfn|Mateos Sáinz de Medrano|2004|p=189}}{{Sfn|Mateos Sáinz de Medrano|2004|p=114}} The rest of the family settled in [[Cape Town]], where the family was joined by a younger sister, [[Princess Irene of Greece and Denmark|Princess Irene]], born in 1942.<ref name=Burke/> Prince Constantine, Princess Sofia, their mother and their aunt [[Princess Katherine of Greece and Denmark|Princess Katherine]] were initially lodged with South African Governor-General [[Patrick Duncan (South African politician)|Patrick Duncan]] at his official residence Westbrooke in Cape Town.{{sfn|Mateos Sáinz de Medrano|2004|p=113-115}}{{sfn|Hourmouzios|1972|p=133}}

The group subsequently moved several times until they settled in Villa Irene in [[Pretoria]] with Prime Minister [[Jan Smuts]], who quickly became a close friend of the exiled Greeks.{{sfn|Mateos Sáinz de Medrano|2004|p=113-115}}{{sfn|Hourmouzios|1972|p=136 og 144}}{{sfn|Tantzos|1990|p=21}} From early 1944, the family again took up residence in Egypt. In January 1944, Frederica was reunited with Paul in [[Cairo]], and their children joined them in March of that year. Despite their difficult financial circumstances, the family then established friendly relations with several Egyptian personalities, including [[Queen Farida]], whose daughters were roughly the same age as Constantine and his sisters.{{sfn|Mateos Sáinz de Medrano|2004|p=115-116}}

===After World War II and return to Greece===

In 1944, at the end of World War II, Nazi Germany gradually withdrew from Greece. While the majority of exiled Greeks were able to return to their country, the royal family had to remain in exile because of the growing republican opposition at home. Britain tried to reinstate George II, who remained in exile in London, but most of the resistance, in particular the communists, were opposed. Instead, George had to appoint from exile a Regency Council headed by Archbishop [[Damaskinos of Athens]], who immediately appointed a republican-majority government headed by [[Nikolaos Plastiras]].{{sfn|Van der Kiste|1994|p=170-171}}{{sfn|Hourmouzios|1972|p=164-169 og 171}}{{sfn|Tantzos|1990|p=38-39}} George, who was humiliated, ill and powerless, considered abdicating for a time in favour of his brother, but eventually decided against it.{{sfn|Van der Kiste|1994|p=170-171}}{{sfn|Hourmouzios|1972|p=164-169 og 171}}{{sfn|Tantzos|1990|p=38-39}}

Prince Paul, who was more combative but also more popular than his brother, would have liked to return to Greece as heir to the throne as early as the liberation of Athens in 1944, as he believed that back in his country he would have been quickly proclaimed regent, which would have blocked the way for Damaskinos and made it easier to restore the monarchy.{{sfn|Hourmouzios|1972|p=155}}

However, the unstable situation in the country and the polarisation between communists and bourgeois allowed the monarchists to return to power after the [[1946 Greek legislative election|parliamentary elections of March 1946]]. After becoming [[Prime Minister of Greece|prime minister]], [[Konstantinos Tsaldaris]] organised a [[1946 Greek referendum|referendum on 1 September 1946]] with the aim of allowing George to return to the throne. The majority in the referendum was in favour of reinstating the monarchy, at which time Constantine and his family also returned to Greece. In a country still suffering from rationing and deprivation, they moved back to the villa in Psychikó. It was there that Paul and Frederica chose to start a small school, where Constantine and his sisters received their first education{{sfn|Mateos Sáinz de Medrano|2004|p=117}} under the supervision of [[Jocelin Winthrop Young]], a British disciple of the German-Jewish educator [[Kurt Hahn]].{{sfn|Tantzos|1990|p=61}}{{sfn|Mateos Sáinz de Medrano|2004|p=359}}<ref>{{cite journal|first=Ann|last=Packard|title=Obituary: Jocelin Winthrop-Young OBE, the Gordonstoun ethic ran deep in life and work of educationalist and Hahn disciple|journal=The Scotsman|date=10 March 2012|url=https://www.scotsman.com/news/obituaries/obituary-jocelin-winthrop-young-obe-the-gordonstoun-ethic-ran-deep-in-life-and-work-of-educationalist-and-hahn-disciple-1-2165056}}.</ref>

The tension between communists and conservatives led, in the following years, to the [[Greek Civil War]]. That conflict was fought mainly in northern Greece. The Civil War ended in 1949, with the victory of the bourgeois and royalists, who had been supported by Britain and the United States.<ref>{{Cite web|url=https://www.britannica.com/event/Greek-Civil-War|title=Greek Civil War &#124; Britannica|website=Encyclopædia Britannica|date=13 April 2023 }}</ref>

The first years of Paul's reign did not bring great upheavals in his son's daily life. Constantine and his sisters were brought up relatively simply, and communication was at the heart of the pedagogy of their parents, who spent all the time they could with their children.{{sfn|Celada|2007|p=70}}{{sfn|Mateos Sáinz de Medrano|2004|p=120 og 131–132}} Supervised by various British governesses and tutors, the children spoke English in the family but were also fluent in Greek.{{sfn|Mateos Sáinz de Medrano|2004|p=120}} Until he was nine, Constantine continued to be educated with his sisters and other companions from Athens' wealthier population in the villa at Psychiko.{{sfn|Tantzos|1990|p=61}}

After that age, Paul decided to begin preparing his son for the throne. He then started at the [[Anavryta Experimental Lyceum|Anávryta lyceum]] in [[Marousi]], northeast of Athens, which also followed Kurt Hahn's pedagogy. He attended school there as a boarder between 1950 and 1958,<ref>{{Cite web|url=https://www.infokids.gr/lykeio-anavryton-to-istoriko-protypo/|title=Λύκειο Αναβρύτων: Το ιστορικό πρότυπο σχολείο που φοίτησε ο τέως βασιλιάς Κωνσταντίνος|website=infokids.gr|date=13 January 2023|language=el}}</ref> while his sisters attended school in [[Salem, Baden-Württemberg]], Germany.{{sfn|Tantzos|1990|p=61}}{{sfn|Mateos Sáinz de Medrano|2004|p=124-125}}{{sfn|Hourmouzios|1972|p=216 og 300}} From 1955, Constantine served in all three branches of the Hellenic Armed Forces, attending the requisite military academies. He also attended the [[NATO]] Air Force Special Weapons School in Germany, as well as the [[University of Athens]], where he took courses in the school of law.<ref name="waiting" /> In 1955, he received the title of [[Duke of Sparta]].<ref name="euronews" />

Constantine was an able sportsman. In 1958, Paul gave his son a [[Lightning (dinghy)|Lightning]] class sailing boat for Christmas. Subsequently, Constantine spent most of his free time training with the boat on the Saronic Gulf. After a few months, the Greek Navy gave the prince a [[Dragon (keelboat)|Dragon class sailing boat]], with which he decided to participate in the [[1960 Summer Olympics]] in Rome.{{sfn|Tantzos|1990|p=80-81}} At the opening of the Games in Rome, he was the flag bearer for the Greek team.<ref name="kathi">{{Cite news|url=https://www.kathimerini.gr/society/562222102/o-teos-vasilias-konstantinos-mesa-to-istoriko-archeio-tis-k/|title=Ο τέως βασιλιάς Κωνσταντίνος μέσα από το ιστορικό αρχείο της «Κ»|date=11 January 2023|newspaper=[[Kathimerini]]|language=el}}</ref> He won an Olympic gold medal in the [[Sailing at the 1960 Summer Olympics – Dragon|Dragon event]], which was the first Greek gold medal since the Stockholm [[1912 Summer Olympics]].<ref>{{cite web|url=http://www.olympic.org/medallists-results?athletename=&category=&games=&sport=&event=&mengender=false&womengender=false&mixedgender=false&teamclassification=false&individualclassification=false&continent=1&country=30784&goldmedal=true&silvermedal=false&bronzemedal=false&worldrecord=false&olympicrecord=false&targetresults=true&sortorder=date&resultspageipp=50|title=Olympic Records World Records|publisher=International Olympic Committee|access-date=12 August 2013|archive-date=21 October 2013|archive-url=https://web.archive.org/web/20131021191325/http://www.olympic.org/medallists-results?athletename=&category=&games=&sport=&event=&mengender=false&womengender=false&mixedgender=false&teamclassification=false&individualclassification=false&continent=1&country=30784&goldmedal=true&silvermedal=false&bronzemedal=false&worldrecord=false&olympicrecord=false&targetresults=true&sortorder=date&resultspageipp=50|url-status=live}}</ref> Constantine was the helmsman of their Olympic gold-winning sailing vessel ''Nireus'', and other members of the team included [[Odysseus Eskitzoglou]] and [[Georgios Zaimis]].<ref name="kathi"/>

In 1964, Paul's health deteriorated rapidly. He was diagnosed with [[stomach cancer]] and underwent surgery for an [[ulcer]] in February. Prior to this, Constantine had already been appointed [[regent]] for his ailing father while waiting for his recovery.{{sfnm|Hourmouzios|1972|1p=155|Van der Kiste|1994|2pp=183–184}}<ref>{{cite news|title=Ailing Greek King Names Son Regent|url=https://www.nytimes.com/1964/02/21/ailing-greek-king-names-son-regent.html|access-date=29 April 2016|work=[[The New York Times]]|date=21 February 1964|archive-date=24 July 2016|archive-url=https://web.archive.org/web/20160724083556/http://www.nytimes.com/1964/02/21/ailing-greek-king-names-son-regent.html|url-status=live}}</ref> During his regency, Constantine limited himself to signing decrees and appointing members of the government, as well as accepting their resignations.<ref name="euronews">{{cite news|title=Απεβίωσε ο τέως βασιλιάς Κωνσταντίνος – Μητσοτάκης: «Η Ιστορία θα τον κρίνει δίκαια και αυστηρά» |url= https://gr.euronews.com/2023/01/10/ellada-apeviose-o-teos-vasilias-konstantinos|work=[[Euronews]]|date=11 January 2023|language=el}}</ref> As the king's condition worsened, the crown prince went to [[Tinos]] to attain an icon considered miraculous by the [[Greek Orthodox Church]].

Due to his youth, Constantine was also perceived as a promise of change. Greece was still feeling the effects of the Civil War and society was strongly polarised between the [[royalist]]-conservative right wing and the liberal-[[socialism|socialist left]] wing. The accession of Constantine came shortly after the [[1964 Greek legislative election|election]] of [[Center Union|centrist]] [[Georgios Papandreou|George Papandreou]] as prime minister in February 1964, which ended 11 years of right-wing rule by the [[National Radical Union]] (ERE).

Constantine succeeded to the throne at a time when Greek society was experiencing economic and employment growth.<ref name=jason /> Indicating his refusal to concede any power to the elected government, in September 1964, when there was yet no sign of his conflict with Papandreou, Constantine asked US Ambassador [[Henry Labouisse]] whether he "wanted him to get rid" of Papandreou, although he admitted he was not presently able to do so.<ref>{{harvnb|Kallivretakis|2017|pp=211-212}}</ref> The topic was discussed in subsequent conversations and in January 1965, before the emergence of the ASPIDA case, Cosntantine stated he considered inadvisable for the time being to adopt counsel he was receiving to clash with the Papandreou government due to the popular support it enjoyed.<ref>{{harvnb|Kallivretakis|2017|pp=212-213}}</ref> Political instability worsened in 1965.

Historians have suspected that Constantine and his mother were interested in a coup d'état from mid-1965 at the latest. US Army Attaché Charles Perkins reported that military right-wing group "Sacred Bond of Greek Officers" (IDEA) "plans for coup and military dictatorship in Greece", that Constantine was aware and that the group was aware that any operation in this direction with the cooperation of the US must have the permission of the king.<ref name="Pelt278">{{cite book | last=Pelt | first=M. | title=Tying Greece to the West: US-West German-Greek Relations 1949–1974 | publisher=Museum Tusculanum Press | series=Studies in 20th & 21st century European history | year=2006 | isbn=978-87-7289-583-3 | url=https://books.google.com/books?id=zzCZ3duPMbcC&pg=PA278 | access-date=15 January 2023 | page=278}}</ref> According to Charilaos Lagoudakis, a US State Department expert on Greece, by mid-1966 Constantine had already approved a coup plan.<ref name=Pelt278 /> On the other hand, [[Conservative Party (UK)|Conservative]] [[Member of Parliament (United Kingdom)|MP]] [[C.M.

A traditionalist, right-wing nationalist group of middle-ranking army officers led by Colonel [[Georgios Papadopoulos|George Papadopoulos]] took action first and staged a [[Greek junta|coup d'état on 21 April]] using the fear of "communist danger" as the main reason for the coup.<ref name=sansi2 /> Tanks rolled through the streets of Athens, rifle shots were heard and military songs were played on the radio until the announcement that "The Hellenic Armed Forces have undertaken the governance of the country" was made public.

From his inauguration as king, Constantine already manifested his disagreements with [[Archbishop Chrysostomos II of Athens]]. With the military dictatorship, he had the opportunity to be removed from the Greek Orthodox Cephaly, in fact it was one of the first measures with which Constantine collaborated with the Junta. On 28 April 1967, Chrysostomos II was retained and was forced to resign after having to sign one of the two versions of the letter brought to him by an official of the royal palace. Finally, [[Ieronymos Kotsonis]] was elected as metropolitan by the junta's and Constantine's proposal on 13 May 1967.<ref>{{cite news|url=https://www.vradini.gr/article/politiki/688771-tews-basilias-kwnstantinos-to-xryso-olympiako-metallio-sth-rwmh-kai-oi-gamoi-toy-me-thn-anna-maria|title=Τέως βασιλιάς Κωνσταντίνος: Το χρυσό Ολυμπιακό μετάλλιο στη Ρώμη και οι γάμοι του|date=15 January 2023|first=Dimitris|last=Kafantaris|work=[[Vradyni]]|language=el}}</ref>

Constantine began negotiations with the officials loyal to him in the summer of 1967. His objective was to mobilise the units of the army loyal to him and to restore parliamentary legitimacy. The action was planned by Lieutenant General [[Konstantinos Dovas]].<ref name=huff /> Several military authorities joined the plan, including lieutenant general Antonakos, chief of the air force, Konstantinos Kollias, lieutenant general Kechagias, Ioannis Manettas, brigadier generals Erselman and Vidalis, major general Zalochoris, and others, so it was expected that the counterattack would be successful.<ref name=huff /> The king communicated with [[Konstantinos Karamanlis]], who was exiled in Paris and aware of the plot, and attempted to persuade him return to assume the post of prime minister if this movement was successful, but he refused.<ref name=huff /> The main objective of the plan drawn up by the movement was that all the units initiated would occupy [[Thessaloniki]] and the king would send a message to the public.<ref name=huff /> It would follow the military operations in [[Tempi (municipality)|Tempi]], Larissa and Lamia by the army and the swearing in of a new government by Archbishop Ieronymos with the participation of the centrist [[Georgios Mavros]].<ref name=huff /> Constantine and the involved officials began to realise that the plan could fail as they didn't count on the active support of American intelligence, who were aware of the details of the plan.<ref name=huff /> They intended to initiate their plan on the day of a military parade scheduled for 28 October, but the junta-installed Chief of the [[Hellenic Army General Staff]], [[Odysseas Angelis]], refused to mobilise the units that [[Georgios Peridis]] requested. The abortive attempt, along with the visit of Constantine together with Peridis to some military divisions, were noted by the junta.<ref name=huff />

On the morning of the day the countercoup had been rescheduled to, 13 December 1967, after eight months of planning the countercoup,<ref name="KingStory"/> the royal family flew to [[Kavala]], east of Thessaloniki, accompanied by Prime Minister Konstantinos Kollias who was informed at that moment of Constantine's plan. They arrived at 11:30 a.m. and were well received by the citizens.<ref name=huff /> But some conspirators were neutralised, such as General Manettas, and Odysseas Angelis informed the public of the plan, asking citizens to obey his orders minutes before telecommunications were cut off.<ref name=huff /> By noon, all the airbases, except one in Athens, had joined the royalist movement, and fleet leader Vice Admiral Dedes, before being arrested, ordered successfully the whole fleet sail towards Kavala in obedience to the king.<ref name=huff /> They did not manage to take Thessaloniki and it soon became apparent that the senior officers were not in control of their units. This, along with the arrest of several officers, including the capture of Peridis that afternoon, and the delay in the execution of some orders, led to the countercoup's failure.<ref name=huff />

The junta, led by Georgios Papadopoulos, on the same day appointed General [[Georgios Zoitakis]] as [[Regent of Greece]]. Archbishop Ieronymos swore Zoitakis into office in Athens.<ref name=huff /> Constantine, the royal family and Konstantinos Kollias took off in torrential rain from Kavala for exile in Rome, where they arrived at 4&nbsp;p.m. on 14 December, with their plane having only five minutes of fuel left.<ref name="KingStory"/> In 2004, Constantine said that he would have done everything the same, but with more caution. Two weeks after his exile, photos of Constantine and his family celebrating Christmas with normality in the [[Greek Ambassador to Italy]]'s home reached Greek media, which didn't do Constantine's reputation "any favour".<ref name="KingStory"/> He remained in exile in Italy through the rest of military rule, although he technically continued as king until 1 June 1973. He was never to return to Greece as a reigning monarch.<ref name=huff />

==Restoration of democracy and the referendum==
{{main|Metapolitefsi}}
The [[Turkish invasion of Cyprus]] led to the downfall of the military regime, and Konstantinos Karamanlis returned from exile to become prime minister. The 1973 republican constitution was regarded as illegitimate, and the new administration issued a decree restoring the 1952 constitution. Constantine expected an invitation to return.<ref name="waiting" /> On 24 July, he declared his "deep satisfaction with the initiative of the armed forces in overthrowing the dictatorial regime" and welcomed the advent of Karamanlis as prime minister.<ref>{{cite news|url=https://www.nytimes.com/1974/07/25/archives/constantine-declines-to-predict-when-he-will-return-to-greece.html|title=Constantine Declines to Predict When He Will Return to Greece|work=[[The New York Times]]|date=25 July 1974|first=Richard|last=Eder}}</ref>

Following the appointment of a civilian government in November 1974 after the [[1974 Greek legislative election|first post-junta legislative election]], Karamanlis called a [[1974 Greek republic referendum|referendum]], held on 8 December 1974, on whether Greece would restore the monarchy or remain a republic.<ref name=lifo /> Although he had been the leader of the traditionally monarchist right, Karamanlis made no attempt to encourage a vote in favour of restoring the monarch. The king was not allowed by the government to return to Greece to campaign for the restoration of constitutional monarchy. He was only allowed to broadcast to the Greek people from London on television. Analysts claim this was a deliberate act by the government to reduce the possibility of a vote in favour of restoration.<ref>{{cite web | url=http://www.royalchronicles.gr/1974referendumgreece/ | title=The Referendum | website=The Royal Chronicles | access-date=19 November 2020 | archive-date=1 November 2020 | archive-url=https://web.archive.org/web/20201101044745/http://www.royalchronicles.gr/1974referendumgreece/ | url-status=live }}</ref>

Constantine, speaking from London, said he had made mistakes in the past. He said he would always be supportive of democracy in future and promised that his mother would stay away from the country.<ref name="waiting"/> Local monarchists campaigned on his behalf.

===Abortive conspiracies===
[[File:Bezoek premier Karamanlis van Griekenland Van Agt in gesprek met Karamanlis, Bestanddeelnr 929-6548 (cropped).jpg|thumb|upright|[[Konstantinos Karamanlis]] in 1978]]
The posthumously published archives of Konstantinos Karamanlis, as well as the memoirs of Constantine's former marshal of the court, {{ill|Leonidas Papagos (ambassador)|el|Λεωνίδας Παπάγος|lt=Leonidas Papagos}}, revealed that from 1975 to 1978, Constantine was involved in a conspiracy to overthrow the democratic government, including the assassination of Karamanlis and a followed referendum on the monarchy.<ref name="Kathimerini">{{cite web | url = https://www.kathimerini.gr/investigations/562234321/i-synomosia-toy-konstantinoy-gia-tin-exoydeterosi-karamanli-i-apokalypsi-tis-k/ | title = Η συνωμοσία του Κωνσταντίνου για την «εξουδετέρωση Καραμανλή» – Η αποκάλυψη της «Κ» | date = 18 January 2023 | access-date = 28 January 2023 | language = Greek | work= [[Kathimerini]]}}</ref> Constantine's close confidant, Michail Arnaoutis, approached high-ranking officers to try to gain their support. After some naval officers approached expressed doubts that Arnaoutis spoke for the former king, the chief engineer of the fleet was invited to London, where Constantine confirmed the basic outline of the plot as relayed by Arnaoutis.<ref name="Kathimerini"/> The naval officers approached informed Karamanlis, who sent Papagos to warn Constantine to "stop conspiring" and the former monarch denied knowledge of the conspiracy, but when called upon, Arnaoutis confirmed his contacts with officers in Greece in the presence of both Constantine and Papagos.<ref name="Kathimerini"/> The events were confirmed in 1999 by one of the officers whom Arnaoutis had approached, Vice Admiral [[Ioannis Vasileiadis]], after the publication of Papagos' memoirs. According to Vasileiadis, Arnaoutis said that Constantine had contacted the [[Shah of Iran]] in order to prevent possible Turkish military action during the coup.<ref name="Kathimerini"/><ref name="Vasileiadis">{{cite web | url = https://www.tovima.gr/2008/11/24/politics/to-basiliko-praksikopima-poy-den-egine/ | title = Το βασιλικό πραξικόπημα που δεν έγινε | publisher = [[To Vima]] | language = Greek | date = 6 June 1999 | access-date = 28 January 2023}}</ref>

Karamanlis was also alerted to Constantine's suspicious activities by the British secret services, who had apparently taped his conversations with Greek visitors. In October 1976, the Greek prime minister was informed by the British ambassador that Constantine, while not the driving force behind the conspiracy, was very much aware of it and did nothing to discourage it.<ref name="Kathimerini"/> The British also provided warnings that sympathizers had informed Constantine that a coup would take place in November 1976, led by low-ranking army officers loyal to former dictator [[Dimitrios Ioannidis]]. Karamanlis and his chief diplomatic adviser, [[Petros Molyviatis]], applied pressure on both the British and US governments, which led to a personal intervention by British prime minister [[James Callaghan]], who warned Constantine off. The Greek government repeatedly sent envoys to the former king for the same purpose, but he denied any knowledge of the affair.<ref name="Kathimerini"/> Karamanlis chose not to publicise it in order to not destabilise the fragile democratic system in Greece.<ref name="Kathimerini"/> Nevertheless, in October 1978, Constantine and Arnaoutis were recorded by Greek agents to have sought contact with military and political leaders, trying to win them over to the cause of a royal restoration.<ref name="Kathimerini"/>

===Visits to Greece===
====12 February 1981====
The first visit of Constantine and the former royal family to Greece took place on 12 February 1981, on the occasion of the funeral of his mother, Frederica. She had died in Madrid on 6 February, and it was the wish of both her and her descendants that she be buried next to her husband in the cemetery of [[Tatoi]]. As soon as Constantine's communication with the government of then Prime Minister [[George Rallis]] about the details of the funeral became known to the press, an intense political dispute erupted. Only six years had passed since the referendum and the controversies between the two sides - pro-royalist and anti-royalist - were still fresh. The opposition even raised the issue of a burial ban, a demand that was clearly illegal but indicative of the polarisation that existed.<ref>{{cite web |author=<!-- not stated --> |date=15 January 2023 |title=1981: Το ΠΑΣΟΚ, ο Ανδρέας , η "Αλλαγή" και ο θάνατος της Φρειδερίκης: "Να μην παραστεί κανείς Υπουργός" |url=https://thesocialist.gr/1981-to-pasok-o-andreas-i-allagi-kai-o-thanatos-tis-freiderikis-na-min-parastei-kaneis-ypourgos/ |website=thesocialist.gr |language=Greek |publisher= |trans-title=1981: PASOK, Andreas, "Change" and the death of Frederica: "No Minister should attend"}}</ref> The Rallis government was therefore asked to find a compromise solution.
Although the royal entourage's preference for a [[Lying in state|lay-in-state ceremony]] in [[Metropolitan Cathedral of Athens|Athens metropolitan cathedral]]  followed by a burial in Tatoi, the Rallis government, in the midst of fierce confrontations with the opposition, decided that both the funeral and the burial should take place in Tatoi to avoid the possibility of violent clashes between pro- and anti-royal supporters.<ref>{{cite web |author=<!-- not stated --> |date=12 January 2023 |title=Τέως Βασιλιάς Κωνσταντίνος: Η κηδεία της μητέρας του, Φρειδερίκης, είχε ανάψει φωτιές |url=https://www.in.gr/2023/01/12/stories/teos-vasilias-konstantinos-kideia-tis-miteras-tou-freiderikis-eixe-anapsei-foties/ |website=in.gr |language=Greek |publisher= |trans-title=Former King Constantine: The funeral of his mother, Frederica, was a firestorm}}</ref> Constantine and his family could only stay on Greek soil for six hours, as long as they needed to carry out their duties.

The funeral and burial took place under police protection. However, the police were unable to keep the crowds of  supporters of the former king away from the site.<ref>{{cite web |author=<!-- not stated --> |date=15 January 2023 |title=Η τελευταία κηδεία στο Τατόι: Η Φρειδερίκη αναπαύθηκε εν πολέμω - Τεθωρακισμένα, βολές του Τύπου και το ΠΑΣΟΚ στα χαρακώματα με την κυβέρνηση Ράλλη |url=https://www.ethnos.gr/history/article/241779/hteleytaiakhdeiastotatoihfreiderikhanapaythhkeenpolemotethorakismenabolestoytypoykaitopasokstaxarakomatamethnkybernhshrallh |website=ethnos.gr |language=Greek |publisher= |trans-title=The last funeral in Tatoi: Frederick rested in war - Armoured vehicles, press shots and PASOK in the trenches with the Rallis government}}</ref>

[[File:1993 trip of Constantine II of Greece.png|thumb|right|220px|Map of Constantine's 1993 journey in Greece, starting in Thessaloniki and ending in Neapoli Voion.]]
At the funeral of King [[Baudouin of Belgium]], a private agreement was made between Constantine and the new conservative Greek prime minister, [[Konstantinos Mitsotakis]], that allowed Constantine and his family to temporarily return to Greece on a holiday.<ref name="1993trip">{{cite AV media|url=https://www.youtube.com/watch?v=lkA7CC1Y8pA|people=Constantine II; Anne-Marie; Scott, Selina|title=Once A King|date=1993|work=[[Sky News]] via [[YouTube]]|access-date=23 December 2023}}</ref>{{Failed verification|date=January 2025}} Constantine was accompanied by his wife Anne-Marie, their five children, and his sister Irene. The family had decided that yachting around Greece would be the best way to showcase the country to their children, who were unable to grow up within Greece.<ref name="1993trip"/> The opposition claimed that the government was attempting to reinstate the monarchy.<ref name="1993trip"/> On 9 August 1993, the family departed from the UK on two planes, including a jet donated to Constantine by King [[Hussein of Jordan]]. The Greek government was unaware of Constantine and his family's holiday, which had been planned and charted by [[Princess Alexia of Greece and Denmark|Princess Alexia]]. Constantine, and then his family a few hours later, landed in Thessaloniki, before boarding a yacht.<ref name="1993trip"/>{{Failed verification|date=January 2025}}

The family's yacht then travelled 300 metres off the shore of [[Mount Athos]]. Constantine and his two eldest sons, [[Crown Prince Pavlos]] and [[Prince Nikolaos]], travelled upon a dinghy to get to the mainland, where women were not allowed to visit.<ref name="1993trip"/>{{Failed verification|date=January 2025}} Upon arriving, Constantine noticed his portrait in every monastery and learnt that the monks there had been praying for him every day since his exile. Nine monks followed Constantine back to their yacht to bless the rest of his family, display holy relics and present gifts.<ref name="1993trip"/>{{Failed verification|date=January 2025}} Constantine then took a helicopter and landed on a soccer pitch in [[Florina]], where "hundreds" of people greeted him with handshakes and flowers. Constantine's decision to land in Florina was named a "politically sensitive spot to appear in" in view of the region's greater support for the monarchy over other regions and due to the [[Macedonia naming dispute]]. Constantine and his family took a van north in order see the northernmost part of Greece, and were reportedly followed by between 50 and 100 cars. However, the Greek government had organised for the police to block the road, claiming that Constantine's journey was "a political step", rather than touristic.<ref name="1993trip"/>{{Failed verification|date=January 2025}} Protestors attempted to open up the road, but failed. In the next village the family stopped at, a local government official told Constantine that he would be kicked out of Greece if he did not act like a tourist.<ref name="1993trip"/>{{Failed verification|date=January 2025}}

Following this clash between police and protestors in support of Constantine, Mitsotakis made a public statement explaining that the government "had no prior knowledge of the visit and had never agreed to it. Strong action will be taken if the ex-king violates our conditions."<ref name="1993trip"/> Afterwards, Constantine and his family returned to Athens to visit Tatoi Palace and his parents' graves, where a short memorial service was held. During this trip, Constantine chose where his future tomb would be. Telling [[Sky News]] presenter Selina Scott, Constantine said that having to leave his belongings when going into exile taught him that "material things are not that important".<ref name="1993trip"/> He also expressed his wishes to move back into the property and clean up the land surrounding it. Constantine was then warned by the government to move on from Tatoi and alerted them of protestors who were threatening to burn Tatoi's forestry down.<ref name="1993trip"/>{{Failed verification|date=January 2025}}

Whilst travelling to [[Spetses]], the government ordered that Constantine should not travel to heavily populated areas, to which Constantine said, "It's a free country".<ref name="1993trip"/> When he arrived at a port in Spetses, a harbour policeman jumped onto their boat, but Constantine pushed him to the side and set foot on the mainland. A crowd greeted Constantine and his family, but at night and during the following day, their yacht was surrounded by government ships and flown over by military planes. Constantine then contacted [[Sky News UK]] and was interviewed by presenter David Blaine, to whom Constantine told on live air that he was being harassed by the government, who had "frightened the daylights" out of his children.<ref name="1993trip"/> Constantine's yacht was on course to stop at [[Gytheio]], where a reported 5,000 to 10,000 people were waiting for him. Military warships were denying the yacht's progress towards the town, so Constantine stopped in [[Neapoli Voion]], where there was a crowd of a few hundred people, but also many anti-monarchists. Following this stop, Constantine and his family returned to the UK.<ref name="1993trip"/>{{Failed verification|date=January 2025}}

===Legal quarrels over the royal properties===
====Properties and citizenship====
[[File:Anaktora1.jpg|thumb|[[Tatoi Palace]] (''pictured'') was seized from Constantine by the government.]]
A long-standing dispute between the former royal family and the Greek state over the ownership of movable and immovable property which, prior to the constitutional change of the Metapolitefsi, was considered to be the property of King Constantine was resolved in 2002. The [[European Court of Human Rights]] condemned Greece for violating [[European Convention on Human Rights#Convention protocols|Article 1 of the First Protocol]] and awarded the former royal family compensation of €13.7 million.<ref group="note">According to [[Evangelos Venizelos]] "The Strasbourg judgment accepts that [[Tatoi Palace]], [[Mon Repos, Corfu]] and [[Royal estate of Polydendri]] constitute the individual property of the applicants. It accepts that Law No. 2215/1994 is in conformity with the Greek Constitution and that it constitutes the legal basis for the valid [[Nationalization#Expropriation|expropriation]] of such property for sufficient reasons of public interest. It requests, however, that an adequate or, rather, "some" compensation be determined for the applicants, since their rights under Article 1 of the Additional Protocol to the ECHR have been violated."</ref> The legal basis of the dispute was determined by the interpretation of royal property as private or public. According to the royal family, the property was acquired by their predecessors through legal means (purchases) from their personal estates and was therefore considered the inheritance of the former king. In the eyes of the Greek public, however, the property was a by-product of the institution of the [[monarchy]] and served to enable the supreme ruler to exercise his role as monarch. With the demise of the monarchy, the property should automatically pass to the state.<ref name="EV">{{cite web |author=Evangelos Venizelos |date=24 November 2008 |title=Το βάρος της Ιστορίας και η βασιλική περιουσία |url=https://www.tovima.gr/2008/11/24/opinions/to-baros-tis-istorias-kai-i-basiliki-perioysia/?fbclid=IwAR3RG3t4HRwFBOlQ9lUpCZuXRaxfUcWMJU1bWCxFXmoxdPs1O-Cq6vkBa-k |website=tovima.gr |language= Greek|trans-title=The weight of history and the royal estate}}</ref>

In 1973, Decree No. 225 expropriated the movable and immovable property of the former king and members of the royal family for the benefit of the state. In September 1974, the government of National Salvation, headed by [[Constantine Karamanlis]] revoked the junta's decree in anticipation of the referendum that would determine the country's constitution. Although the [[1974 Greek republic referendum|referendum]] abolished the monarchy, the government did not proceed with the confiscation of property. Instead, it set up a seven-member commission to administer the property. This committee later handed over its responsibilities to the legal representative of the royal family in Greece, retired admiral Mario Stavridis.<ref name="Ethnos">{{cite web |author=Νίκος Σβέρκος (Nikos Sverkos) |date=21 December 2024 |title=«Ντε Γκρες»: Η ιστορία της διαμάχης για το όνομα και την περιουσία των Γκλύξμπουργκ|url=https://www.ethnos.gr/Politics/article/346895/ntegkreshistoriathsdiamaxhsgiatoonomakaithnperioysiatongklyxmpoyrgk |website=ethnos.gr |language=greek |publisher=Ethnos (newspaper) |trans-title="De Grece": the story of the dispute over the name and property of the Glyxburgs}}</ref> Thus, members of the royal family continued to declare their property as inherited and to file inheritance and income tax returns, and the tax administration continued to assess taxes and impose surcharges and fines. In 1984, Constantine took the initiative to approach the Greek government to settle the former royal family's tax debts to the Greek state. An agreement was finally reached in 1992, under the government of [[Konstantinos Mitsotakis]] with Law 2086/1992. The agreement - which was never implemented - included the payment by the royal family of 183,000,000 [[Modern drachma|drachmas]] in cash from the total amount of [[inheritance tax]] due, while the rest was to be covered by the concession of 200 acres to the state, 400 acres to the "World Hippocratic Hospital Foundation and Research Centre" to be built a huge hospital complex, and 37,426 acres to the "Tatoi National Park".<ref name="royalchronicles">{{cite web |author=Ανδρέας Μέγκος (Andreas Megos) |date=9 September 2024|title=Η ιδιωτική περιουσία της Ελληνικής Βασιλικής Οικογένειας: Ιστορική αναδρομή μιας πολύκροτης υπόθεσης |url=https://www.royalchronicles.gr/vassiliki-periousia-istorikh-anadromi-2024/ |website=royalchronicles.gr |language=greek |publisher= |trans-title=The private property of the Greek Royal Family: Historical review of a controversial case}}</ref> In the agreement there was no specific provision for the so-called "summer palace" of Tatoi, for Mon Repo, for Polydendri and for mobile things. All these were considered the King's property.<ref name="Ethnos" />

In 1993, on the occasion of the visit of the royal family to Greece, [[Andreas Papandreou]] announced the legislative settlement of the outstanding issues. In fact, on the basis of the consultative document drafted by [[Evangelos Venizelos]] for the Municipality of [[Corfu]] to strengthen their claim to [[Mon Repos, Corfu|Mon Repos]],<ref>{{cite web |author=Χρήστος Λογαράς |date=22 December 2024 |title=Τέως βασιλική οικογένεια: Τίτλοι τέλους και στις υποσημειώσεις |url= https://www.tovima.gr/print/politics/teos-vasiliki-oikogeneia-titloi-telous-kai-stis-yposimeioseis/ |website= |language=Greek |publisher= |trans-title=Former royal family: end titles and footnotes}}</ref> when  [[PASOK]] returned to power under, it abolished the previous law and replaced it with 2215/1994. The Law confiscated the King's property for the benefit of the state without the right to compensation and deprived the members of the royal family of their Greek citizenship. The royal family immediately appealed to the country's civil courts. Although upheld by the [[Supreme Civil and Criminal Court of Greece]], the decision was overturned by the [[Council of State (Greece)|Council of State]]. The [[Special Highest Court]], to which the case was referred in 1997, agreed with the Council of State. All legal remedies in Greece had been depleted. The royal family therefore turned to the European courts.<ref>{{cite web |author=<!-- not stated --> |date=11 January 2023 |title=έως βασιλιάς Κωνσταντίνος: Η σύγκρουση με το ελληνικό κράτος για τη βασιλική περιουσία |url=https://www.in.gr/2023/01/11/stories/teos-vasilias-konstantinos-sygkrousi-elliniko-kratos-gia-ti-vasiliki-periousia/|website=in.gr |language=Greek |trans-title=Former King Constantine: The conflict with the Greek state over the royal property}}</ref>

An appeal to the [[European Commission of Human Rights]] was lodged by Constantine, Anna-Marie, their five children, Princess Irene and Princess Catherine. His sister, [[Queen Sofía of Spain|Queen Sophia]], did not take part because she had already renounced her rights to the estate. The court allowed the appeal, but only for Constantine, [[Princess Irene of Greece and Denmark|Irene]] and [[Princess Katherine of Greece and Denmark|Catherine]]. In October 1998, the European Commission admitted the property issue when all 30 judges unanimously ruled that human rights had been violated and referred the matter to the European Court of Human Rights.<ref name="royalchronicles"/> Constitutional lawyer [[Nikos Alivizatos]], a member of the team of lawyers who represented the Greek State in the trial, pointed out that the trial was considered historic, as it was the most important property case to come before them. The former royal family challenged the expropriation without compensation of 42,000 acres in Tatoi, 230 acres in Corfu and 33,000 acres in Polydendri, Larissa. The total amount demanded by the former king was 168.7 billion drachmas.<ref name="topontiki">{{cite web |author=<!-- not stated --> |date= |title=Η ιστορική δίκη του τέως για τη βασιλική περιουσία – Τι γράφει σχετικά ο Ν.

The court decision also ruled that Constantine's human rights were not violated by the Greek state's decision not to grant him Greek citizenship and passport unless he adopts a surname. Constantine said of this "the law basically said that I had to go out and acquire a name. The problem is that my family originates from Denmark and the Danish royal family haven't got a surname."<ref name="Insult"/> Constantine and his family ultimately did not receive their Greek citizenship back. Although originally requesting Spanish citizenships, Anne-Marie eventually requested of her sister, [[Margrethe II of Denmark]], to have Danish diplomatic passports instated in the names of the members of the Greek royal family. She agreed and in their Danish passports, Constantine and Anne-Marie's names were established as "HM King Constantine II" and "HM Queen Anne-Marie".<ref>{{cite web|lang=en|first1=Nicolas|last1=Gage|first2=Joan|last2=Paulson Gage|title=Why Is the King of Greece Living as a Commoner?|work=Town and Country|date=21 August 2015|url=http://www.townandcountrymag.com/society/politics/news/a3607/king-without-a-country/}}</ref><ref>{{cite web|lang=da|title=Grækenland blander sig ikke i Konstantins diplomatpas|work=Berlingske|date=28 October 2011|url=http://www.b.dk/verden/graekenland-blander-sig-ikke-i-konstantins-diplomatpas}}</ref> On 20 December 2024, over two decades after the court ruling and almost two years after Constantine's death, his descendants received Greek citizenship upon adopting the surname "De Grèce" (Ντε Γκρες; "of Greece"), which had been used by [[Prince Michael of Greece and Denmark]], a first cousin of Constantine's father.<ref>[[Efimeris tis Kyverniseos]] Issue (ΦΕΚ) Β΄ 7035/2024, decisions 1 through 10 ''"On the Recognition of Greek nationality of..."''</ref>

====Movable property====
On 8 October 1990, the commissioner of the Royal Estate, Admiral Stavridis, submitted a request for the transfer of the family's "households goods" abroad. After secret talks with then Prime Minister [[Constantine Mitsotakis]], the government accepted the former king's request and on 22 November, the Greek Minister for the Economy, [[Ioannis Palaiokrassas]], and the Minister for Culture, [[Tzannis Tzannetakis]], issued a joint ministerial decision in order to check, register and mark the objects in the collection which were probably prohibited from leaving the country. In February 1991, when the transfer process began, customs officials, an archaeologist and a representative of the National Gallery carried out the registration of the objects. This work was characterized by haste and sloppiness, and did not meet scientific standards.<ref group="note">According to the representative of the National Gallery... ''"It was very cold, it was snowing and we were without heating and without electricity. We were looking at the paintings with a flashlight in our hand. Next to us was constantly a crowd of royalty, led by Admiral Stavridis, who did everything they could to make things difficult for us. They pressed us to finish quickly, when we asked to open a box they started to make a fuss.... The palace was huge and we were not allowed access to all the rooms. The paintings we forbade to leave the country were kept in a separate room. I wonder where they are now."...''</ref> Nevertheless, the list was submitted to the [[National Gallery (Athens)|National Gallery]] in April 1992, although it has not been used for cross-checking since.   On 17 February 1991, nine containers weighing 32 tonnes and containing 1904 boxes were loaded onto a ship leaving [[Piraeus]] for the port of [[Tilbury]] and the former royal residence in London.<ref name="Vima2" >{{cite web |author=Δήμητρα Κρουστάλλη |date=25 November 2008 |title=Ριφιφί στα Θερινά Ανάκτορα |url=https://www.tovima.gr/2008/11/25/archive/rififi-sta-therina-anaktora/ |website=To Vima |language=Greek |publisher= |trans-title=Burglary in the Summer Palace}}</ref>
When a dock worker at the port alerted the newspapers to the transfer, it became public knowledge, and a heated debate ensued. The [[Opposition (politics)|opposition]] claimed that underworld methods had been used, as Parliament had not been informed and all discussions and negotiations had taken place in secret, while public discourse questioned the legality of the transfer and assurances that it would not affect the public interest.<ref>{{cite web |author=Τάκης Κατσιμάρδος |date=31 May 2017 |title=Το μεγάλο ριφιφί Μητσοτάκη – Γλύξμπουργκ στο Τατόι |url=https://info-war.gr/to-megalo-rififi-mitsotaki-glyxbourgk-sto-tatoi/ |website=Info-war. gr|language=Greek |publisher= |trans-title=The great Mitsotakis - Glyxburg burglary in Tatoi}}</ref>
What further discredited the operation of transferring the heirlooms was when it was revealed, 10 years later, that on 13 February 1991, while the place was under guard, a major break-in and robbery of objects of incalculable value took place. The list of stolen goods included jewellery, valuable religious icons, works of art and objects that were classified as unique works of [[cultural heritage]] and could not be legally exported. However, both the [[Hellenic Police]] and Konstantinos' entourage concealed the fact and did not take legal action to solve the theft.<ref>{{cite web |author=Κώστας Χατζίδης|date=7 December 2002 |title=Ντοκουμέντο για τον κλεμμένο θησαυρό του Τατοΐου|url=https://www.tanea.gr/2002/12/07/greece/ntokoymento-gia-ton-klemmeno-thisayro-toy-tatoioy/ |website=Ta Nea |language=Greek |publisher= |trans-title=Document for the stolen treasure of Tatoi}}</ref>

In 2007, 850 valuable objects belonging to the royal estate were auctioned by [[Christie's]] in London. Constantine denied that he was the vendor - he claimed that they had already been sold in 1991  to third parties who auctioned them but journalists disputed the claim.  The Greek government, through then Culture Minister [[Georgios Voulgarakis]], tried to stop the auction, claiming that the items may have been illegally exported from Greece, but the attempt failed.<ref>{{cite web |author=Malcolm Brabant |date=22 January 2007 |title=Greek protest over London auction |url=http://news.bbc.co.uk/2/hi/europe/6289097.stm|website=bbc |location= |publisher= }}</ref>

Following the abolition of the monarchy, Constantine repeatedly stated that he recognised the republic, the laws and the constitution of Greece. He told ''[[Time (magazine)|Time]]'', "If the Greek people decide that they want a republic, they are entitled to have that and should be left in peace to enjoy it."<ref name="ReferenceA">"Throneless abroad: The men who would be king". ''Time''. 3 June 2002. Vol. 159 No. 22.</ref> Constantine and Anne-Marie for many years lived in [[Hampstead Garden Suburb]], London. Constantine was a close friend of his second cousin [[Charles III]], then Prince of Wales, and a godfather to Charles's son, [[Prince William]]. Constantine's 60th birthday lunch marked the first time that Charles and [[Camilla Parker Bowles]] were seen in public together in a relationship.<ref name="KingStory"/> In 2004, Constantine returned to Greece temporarily during the [[2004 Summer Olympics|Athens Olympic Games]] as a member of the International Olympic Committee.<ref>{{cite news|title=The return of the King of Greece for the games in ''Today''|newspaper=[[NBC]]|date=18 August 2004|url=https://www.today.com/id/wbna5723866#.VszNUfnhDIU|access-date=16 April 2021}}</ref> Later that year, when asked whether he thought he would be the last monarch of Greece, Constantine said that it is "very hard" to determine the future.<ref name="KingStory"/> Constantine served as patron of [[Box Hill School]], a private school in [[Mickleham, Surrey|Mickleham]], in the south of England until his death.

According to a nationwide 2007 survey of 2,040 households in Greece conducted on behalf of the newspaper ''[[To Vima]]'', only 11.6% supported a constitutional monarchy. More than half of the respondents, 50.9%, considered that the dictatorship of the junta had brought benefits to Greece.<ref>{{cite web| archive-url=https://web.archive.org/web/20070425203217/http://tovima.dolnet.gr/print_article.php?e=B&f=15044&m=A04&aa=1 | archive-date=25 April 2007 | url=http://tovima.dolnet.gr/print_article.php?e=B&f=15044&m=A04&aa=1 | title=The Greeks are looking for a new strong leader | website=To Vima | access-date=19 November 2020 }}</ref> During the [[2008 Beijing]] and [[2012 London Olympics]], Constantine, in his role as honorary member of the International Olympic Committee, was the official presenter at the sailing medal ceremonies.

In 2013, Constantine pledged in an interview with [[CNN]] that he would never become involved in restoring the monarchy. When asked by reporter [[Richard Quest]] whether he was content with never becoming the monarch again, Constantine said, "If the Greek people are happy with the system they have today, why should I be the one to change it? Just because I would like to be a king again? That would be crazy."<ref>{{cite AV media|url=https://www.youtube.com/watch?v=fo-AHfJMS0Q|people=Constantine II; Quest, Richard|title=King Constantine's Interview with Richard Quest, for CNN|date=2013|work=Via [[YouTube]]|access-date=17 February 2023}}</ref> Later that same year, Constantine returned to reside in Greece after selling his Hampstead house.<ref name=HS>{{cite news|last1=Smith|first1=Helena|title=Greece's former king goes home after 46-year exile|url=https://www.theguardian.com/world/2013/dec/15/greece-former-king-exile-constantine-ii-anne-marie|access-date=3 March 2016|work=The Guardian|date=15 December 2013|archive-date=26 January 2021|archive-url=https://web.archive.org/web/20210126035531/https://www.theguardian.com/world/2013/dec/15/greece-former-king-exile-constantine-ii-anne-marie|url-status=live}}</ref> From 2015 they lived in a villa in the coastal resort town of [[Porto Cheli]] in [[Argolis]] in the [[Peloponnese]] peninsula.<ref>{{cite news|last1=Meisner|first1=Pia|title=Sådan bor Anne-Marie og Konstantin|trans-title=This is how Anne-Marie and Konstantin live|url=https://www.billedbladet.dk/kongelige/graekenland/saadan-bor-anne-marie-og-konstantin|access-date=17 July 2021|work=Billed-Bladet|date=5 August 2020|language=da}}</ref> In November 2015, his autobiography was published in three volumes by the national newspaper, ''[[To Vima]]''.<ref>{{Cite news |title=Εξαντλήθηκε και κυκλοφορεί στα περίπτερα ο α' τόμος του «Βασιλεύς Κωνσταντίνος» |url=https://www.tovima.gr/2015/11/23/politics/eksantlithike-kai-kykloforei-sta-periptera-o-a-tomos-toy-basileys-kwnstantinos/ |website=To Vima |language=el |date=23 November 2015 |access-date=12 July 2023 |url-status=live |archive-url=https://web.archive.org/web/20170106000910/http://www.tovima.gr/politics/article/?aid=756338 |archive-date=6 January 2017}}</ref> On 10 January 2022, he was admitted to the hospital after testing positive for [[COVID-19]], which he had been fully vaccinated against.<ref>{{Cite web|url=https://greekcitytimes.com/2022/01/10/king-constantine-ii-of-greece-admitted-to-hospital-with-covid-19/|title=King Constantine II Of Greece Admitted To Hospital With Covid-19|date=10 January 2022}}</ref>

===Titles and styles===
Until 1994, Constantine's official Greek passport identified him as "Constantine, Former King of the Hellenes". A law passed in 1994 stripped him of his [[Greek citizenship]], [[Greek passport|passport]] and property. The law stated that Constantine could not be granted a Greek passport unless he adopted a surname. Constantine stated, "I don't have a surname — my family doesn't have a surname. The law that Mr Papandreou passed basically says that he considers that I am not Greek and that my family was Greek only so long as we were exercising the responsibilities of sovereign, and I had to go out and acquire a surname. The problem is that my family originates from Denmark, and the Danish royal family haven't got a surname." [[House of Glücksburg|Glücksburg]], he said, was not a family surname but the name of [[Glücksburg|a town]]. He said, "I might as well call myself Mr. [[Kensington]]."<ref>{{Cite magazine |last=Colacello |first=Bob |title=King without a country |url=https://archive.vanityfair.com/article/1995/7/king-without-a-country |magazine=[[Vanity Fair (magazine)|Vanity Fair]] |date=July 1995 |page=47 |access-date=12 July 2023|language=en-US}}</ref>

Constantine freely travelled in and out of Greece on a [[Danish passport]], as ''Constantino de Grecia'' (Spanish for 'Constantine of Greece'),<ref name="enet"/> because Denmark (upon request) issues [[diplomatic passport]]s to any descendants of [[King Christian IX]] and [[Louise of Hesse-Kassel|Queen Louise]], and Constantine was a Prince of Denmark in his own right.<ref>{{Cite web |title=2000–01, 1. samling – Svar på § 20-spørgsmål: Om kong Konstantin har dansk pas.
