The name is derived from the [[Histri]] ({{langx|grc|Ἱστρών έθνος}}) tribes, which [[Strabo]] refers to as living in the region and who are credited as being the builders of the hillfort settlements (castellieri). The Histri are classified in some sources as a "Venetic" [[Illyrians|Illyrian]] tribe with certain linguistic differences from other Illyrians.<ref>Wilkes, J. J. The Illyrians, 1992,{{ISBN|0-631-19807-5}}, page 183,"... We may begin with the Venetic peoples, Veneti, Carni, Histri and Liburni, whose language set them apart from the rest of the Illyrians...."</ref> The [[Ancient Rome|Romans]] described the Histri as a fierce tribe of pirates, protected by the difficult navigation of their rocky coasts. It took two military campaigns for the Romans to finally subdue them in 177 BC. The region was then called together with the Venetian part the X. Roman Region of "Venetia et Histria", the ancient definition of the northeastern border of Italy. [[Dante Alighieri]] refers to it as well, the eastern border of Italy per ancient definition is the river ''[[Raša (river)|Arsia]]''. The eastern side of this river was settled by people whose culture was different from Histrians. Earlier influence of the [[Iapodes]] was attested there, while at some time between the 4th and 1st century BC the [[Liburnians]] extended their territory and it became a part of [[Liburnia]].<ref>M. Blečić, Prilog poznavanju antičke Tarsatike, VAMZ, 3.s., XXXIV 65-122 (2001), UDK 904:72.032 (3:497.5), pages 70, 71</ref> On the northern side, Histria extended much further north and included the Italian city of Trieste.

Some scholars speculate that the names Histri and Istria are related to the Latin name Hister, or [[Danube]] (especially its lower course). Ancient folktales reported —inaccurately— that the Danube split in two or "bifurcated" and came to the sea near [[Trieste]] as well as at the [[Black Sea]]. The story of the "bifurcation of the Danube" is part of the [[Argonaut]] legend. There is also a suspected link (but no historical documentation in support of it) to the commune of [[Istria, Constanța|Istria]] in Constanța, Romania which is named after the ancient city [[Histria (ancient city)|Histria]], named after River Hister.

In the [[Early Middle Ages]], Istria was conquered and occupied by the Goths. Ostrogoth coins were found in Istria, as well as the remains of some buildings. South of [[Poreč]] there are the remains of the church of Sv. Petar, erected in the 5th century (with a baptistery added later), which reportedly served the Arian eastern Goths ruling Istria.<ref name="sonje">{{cite book|last=Šonje|first=Ante|url=|title=Crkvena arhitektura (L'architettura sacra)|pages=45–49, 217, 270|publisher=|year=|isbn=}}</ref><ref name="Bratoz">{{cite book|last=Bratož|first=Rajko|url=|title=The development of the early Christian research in Slovenia and Istria between 1976 and 1986 [article] Lyon, Vienne, Grenoble, Genève, Aoste, 21-28 septembre 1986|page=2370|publisher=Publications de l'École Française de Rome |year=1989|isbn=}}</ref> Most notably, the Goths used [[Istrian stone]] to build their best known monument, the [[Mausoleum of Theodoric]] in [[Ravenna]].

[[Pope Gregory I]] in 600 wrote to bishop of [[Salona]] Maximus in which he expresses concern about arrival of the [[Slavs]], ''"Et quidem de Sclavorum gente, quae vobis valde imminet, et affligor vehementer et conturbor.

After the fall of the [[Western Roman Empire]], the region was pillaged by the [[Goths]], the [[Eastern Roman Empire]], and the Avars.

===Middle Ages===
[[File:Oton Ivekovic, Dolazak Hrvata na Jadran.jpg|thumb|[[Oton Iveković]], ''The Croats' arrival at the Adriatic Sea'']]
The first [[History of Istria#Avaro-Slavic invasions and settlement|Avaro-Slavic invasion of Istria]] was recorded in 599. Another major incursion occurred around 600–602, in which all of Istria was devastated with fire and rapine. This was followed by the 611 invasion, the most devastating for the peninsula. It remains unclear when and how the first Slavic settlement occurred. Traces of early Slavic incursions and settlement are scarce.<ref name="Bekic"/> A few Avar findings have been discovered on the Istrian territory, chiefly around [[Nesactium]].<ref>{{cite book |last1=Štih |first1=Peter |title=The Middle Ages Between the Eastern Alps and the Northern Adriatic |date=2010 |publisher=Brill |isbn=9789004187702 |page=198}}</ref><ref>{{cite news |last1=Begic |first1=Vanesa |title=AVARI I SLAVENI JUŽNO OD DRAVE: Vitrina s dva avarska predmeta iz Arheološkog muzeja Istre |url=https://www.glasistre.hr/izlozbe/avari-i-slaveni-juzno-od-drave-vitrina-s-dva-avarska-predmeta-iz-arheoloskog-muzeja-istre-736459 |publisher=Glas Istre}}</ref> By 642 the Slavs were settled in the peninsula, as indicated by the mission of an abbot Martin, sent by [[Pope John IV]] to rescue captives held by the pagans in Istria and [[Dalmatia (Roman province)|Dalmatia]].<ref name="Bekic">{{cite book |last1=Bekic |first1=Luka |title=The Early Medieval Between Pannonia and the Adriatic |date=2016 |publisher=Archaeological Museum of Istria |pages=1–301}}</ref>

After the barbaric invasions, the western part of Istria was annexed to the [[Kingdom of the Lombards|Lombard]] Kingdom in 751, and then annexed to the Frankish kingdom by [[Pepin of Italy]] in 789.  In 804, the [[Placitum of Riziano]] was held in the Parish of Rižan ({{langx|la|Risanum}}), which was a meeting between the representatives of Istrian towns and castles and the deputies of [[Charlemagne]] and his son Pepin. The report about this judicial diet illustrates the changes accompanying the transfer of power from the Eastern Roman Empire to the [[Carolingian Empire]] and the discontent of the local residents.<ref>{{cite book |editor=Oto Luthar |title=The land between: a history of Slovenia |year=2008 |publisher=Peter Lang |location=Frankfurt am Main |isbn=978-3-631-57011-1 |page=100 |url=https://books.google.com/books?id=G9tDboBJ70EC&pg=PA100}}</ref>

Afterwards it was successively controlled by the dukes of [[Carantania]], [[Merania]], [[Bavaria]] and by the [[patriarch of Aquileia]], before it became the territory of the [[Republic of Venice]] in 1267. The medieval [[Kingdom of Croatia (medieval)|Croatian kingdom]] held only the far eastern part of Istria (the border was near the river [[Raša (river)|Raša]]), but they lost it to the [[Holy Roman Empire]] in the late 11th century.

===Venetian era===

Under [[Pietro II Candiano]], who was [[Doge of Venice]] between 932 and 939, Istrian cities signed an act of devotion to the Venetian rule. On [[Ascension Day]] in 1000, a powerful fleet sailed from Venice to resolve the problem of the Narentine pirates.<ref name=":0">{{Cite web|url=http://www.treccani.it/enciclopedia/pietro-ii-orseolo_(Dizionario-Biografico)/|title=ORSEOLO, Pietro II in "Dizionario Biografico"|website=www.treccani.it|language=it-IT|access-date=2017-09-15}}</ref> The fleet visited all the main Istrian and Dalmatian cities, whose citizens, exhausted by the wars between the Croatian king [[Svetoslav Suronja|Svetislav]] and his brother [[Krešimir III of Croatia|Cresimir]], swore an oath of fidelity to Venice.<ref name=":0" /> In 1145, the cities of Pula, [[Koper]] and [[Izola]] rose against the [[Republic of Venice]] but were defeated, and were since further controlled by Venice.{{sfn|Istra-Istria.hr|loc=VARIOUS RULERS}} During the 13th century, the Patriarchate's rule weakened and the towns kept surrendering to Venice – [[Poreč]] in 1267, [[Umag]] in 1269, [[Novigrad, Istria County|Novigrad]] in 1270, [[Sveti Lovreč]] in 1271, [[Motovun]] in 1278, Kopar in 1279, and [[Piran]] and [[Rovinj]] in 1283.{{sfn|Istra-Istria.hr|loc=VARIOUS RULERS}} Venice gradually dominated the whole coastal area of western Istria and the area to [[Plomin]] on the eastern part of the peninsula.{{sfn|Istra-Istria.hr|loc=VARIOUS RULERS}} The wealthier coastal towns cultivated increasingly strong economic relationships with Venice and by 1348 were eventually incorporated into its territory, while their inland counterparts fell under the sway of the weaker Patriarchate of Aquileia, which became part of the [[House of Habsburg|Habsburg Empire]] in 1374.

On 15 February 1267, Parenzo was formally incorporated with the Venetian state.<ref>John Mason Neale, [https://archive.org/details/notese00neal/page/76 ''Notes Ecclesiological & Picturesque on Dalmatia, Croatia, Istria, Styria, with a visit to Montenegro''], pg. 76, J.T. Hayes - London (1861)</ref> Other coastal towns followed shortly thereafter. [[Bajamonte Tiepolo]] was sent away from Venice in 1310, to start a new life in Istria after his downfall. A description of the 16th-century Istria with a precise map was prepared by the Italian geographer [[Pietro Coppo]]. A copy of the map inscribed in stone can now be seen in the Pietro Coppo Park in the center of the town of [[Izola]] in southwestern [[Slovenia]].<ref>{{cite web |url=http://revitas.org/en/tourist-itineraries/historic-urban-cores/izola,18/izola,63.html |title=Historic Urban Cores: Izola |publisher=REVITAS – Revitalisation of the Istrian hinterland and tourism in the Istrian hinterland |access-date=1 June 2015 |url-status=live |archive-url=https://web.archive.org/web/20151117024533/http://revitas.org/en/tourist-itineraries/historic-urban-cores/izola,18/izola,63.html |archive-date=17 November 2015}}</ref>

===Habsburg Monarchy (1797–1805)===
The Inner part of Istria around Mitterburg ([[Pazin]]) had been part of the [[Holy Roman Empire of the German Nation|Holy Roman Empire]] for centuries, and more specifically part of the [[Habsburg monarchy|domains of the Austrian Habsburgs]] since the 14th century. In 1797, with the [[Treaty of Campo Formio]], the Venetian parts of the peninsula also passed to the Habsburg monarchy which became the [[Austrian Empire]] in 1804.<ref>Stephens, Henry Morse (2008).

===Napoleonic era (1805–1814)===
[[File:1807KingdomItaly.jpg|thumb|The [[Napoleonic Kingdom of Italy]] from 1806 to 1810 included Istria that had belonged to Venice until 1797]]
The French victory of 1809 compelled Austria to cede a portion of its South Slav lands to France. Napoleon combined Istira, [[Carniola]], western [[Carinthia]], Gorica ([[Gorizia]]), [[Trieste]] and parts of Croatia, Dalmatia, and Dubrovnik to form the [[Illyrian Provinces]].<ref name="Illyrian">{{Cite web |title=Illyrian Provinces {{!}} historical region, Europe {{!}} Britannica |url=https://www.britannica.com/place/Illyrian-Provinces |access-date=2022-07-11 |website=www.britannica.com |language=en}}</ref> The Code Napoléon was introduced, and roads and schools were constructed.

After this seven-year period, the Austrian Empire regained Istria, which became part of the constituent [[Kingdom of Illyria (1816–49)|Kingdom of Illyria]]. This kingdom was broken up in 1849, after which Istria formed part of [[Austrian Littoral]], also known as the "Küstenland", which also included the city of Trieste and the [[Gorizia and Gradisca|Princely County of Gorizia and Gradisca]] until 1918. At that time the borders of Istria included part of what is now Italian Venezia-Giulia and parts of modern-day Slovenia and Croatia, but not the city of Trieste.

Many [[Istrian Italians]] looked with sympathy towards the [[Risorgimento]] movement that fought for the unification of Italy.<ref name="corsadelricordo">{{cite web|url=http://www.corsadelricordo.it/la-storia|title=Trieste, Istria, Fiume e Dalmazia: una terra contesa|access-date=2 June 2021|language=it}}</ref> However, after the [[Third Italian War of Independence]] (1866), when the [[Veneto]] and [[Friuli]] regions were ceded by the [[Austrian Empire|Austrians]] to the newly formed [[Kingdom of Italy (1861–1946)|Kingdom Italy]], Istria remained part of the [[Austro-Hungarian Empire]], together with other Italian-speaking areas on the eastern Adriatic. This triggered the gradual rise of [[Italian irredentism]] among many Italians in Istria, who demanded the unification of Istria with Italy. The Italians in Istria supported the Italian [[Italian unification|Risorgimento]]: as a consequence, the Austrians saw the Italians as enemies and favored the Slav communities of Istria,<ref name="ReferenceB">''Die Protokolle des Österreichischen Ministerrates 1848/1867.

Although a member of the [[Central Powers]], Italy remained neutral at the start of WWI, and soon launched secret negotiations with [[Triple Entente|the Triple Entente]], bargaining to participate in the war on its side, in exchange for significant territorial gains.<ref>{{Cite journal |last=Cattaruzza |first=Marina |date=2011 |title=The Making and Remaking of a Boundary – the Redrafting of the Eastern Border of Italy after the two World Wars |url=https://www.jstor.org/stable/26265925 |journal=Journal of Modern European History / Zeitschrift für moderne europäische Geschichte / Revue d'histoire européenne contemporaine |volume=9 |issue=1 |pages=66–86 |doi=10.17104/1611-8944_2011_1_66 |issn=1611-8944 |jstor=26265925 |s2cid=145685085|url-access=subscription}}</ref> To get Italy to join the war, the secret [[Treaty of London (1915)|1915 Treaty of London]] the Entente promised Italy Istria and parts of [[Dalmatia]], [[South Tyrol]], the Greek [[Dodecanese Islands]], parts of Albania and Turkey, plus more territory for Italy's North Africa colonies.

After the war, Italy annexed Istria. Istria's political and economic importance declined under Italian rule, and after the fascist takeover of Italy in 1922 the Italian government began a campaign of forced [[Italianization]]. In 1926, the use of Slavic languages in schools and government was banned, even Slavic family names were Italianized to suit the fascist authorities.<ref name="Minahan">{{cite book |last1=Minahan |first1=James |title=One Europe, Many Nations: A Historical Dictionary of European National Groups |date=2000 |publisher=Greenwood Publishing Group |isbn=978-0313309847 |pages=340–341}}</ref> Slavic newspapers and libraries were closed, all Slavic cultural, sporting, business and political associations were banned.

In World War II, Istria became a battleground of competing ethnic and political groups. Istrian nationalist groups which were pro-fascist and pro-Allied and Yugoslav-supported pro-communist groups fought with each other and the Italian army. After the German withdrawal in 1945, Yugoslav partisans gained the upper hand and began a violent purge of real or suspected opponents in an "orgy of revenge".<ref name=Minahan />

===SFR Yugoslavia (1947–1991)===
{{See also|Istrian–Dalmatian exodus|Morgan Line}}
[[File:Italians leave Pola.jpg|thumb|[[Istrian Italians]] leave [[Pula]] in 1947 during the [[Istrian–Dalmatian exodus]]]]
After the end of [[World War II]], Istria was ceded to [[Socialist Federal Republic of Yugoslavia|Yugoslavia]], except for a small part in the northwest corner that formed Zone B of the provisionally independent [[Free Territory of Trieste]]; Zone B was under Yugoslav administration and after the ''[[de facto]]'' dissolution of the Free Territory in 1954 it was also incorporated into Yugoslavia. Only the small town of [[Muggia]], near [[Trieste]], being part of Zone A remained with Italy.<ref name="Pizzi">Katia Pizzi, [https://books.google.com/books?id=-bGYecgxhusC&pg=PA25 ''A city in search of an author: the literacy identity of Trieste''], pg. 23, Sheffield Academic Press (2002), {{ISBN|1-84127-284-1}}</ref>

The events of the period are visible in [[Pula]]. The city, located on the southernmost tip of the Istrian peninsula, had an [[Istrian Italians|Istrian Italian]] majority. Between December 1946 and September 1947, a large proportion of the city's inhabitants were [[Istrian exodus|forced to emigrate to Italy]].<ref name="Pizzi"/> Most of them left in the immediate aftermath of the signing of the [[Paris Peace Treaties, 1947|Paris Peace Treaty]] on February 10, 1947 which granted Pula and the greater part of Istria to Yugoslavia.

===After the breakup of Yugoslavia (after 1991)===
The division of Istria between Croatia and Slovenia runs on the former republic borders, which were not precisely defined in the former Yugoslavia. [[Croatia–Slovenia border disputes|Various points of contention remain unresolved between the two countries]] regarding the precise line of the border.<ref>Julio Aramberri, Richard Butler, [https://books.google.com/books?id=0qW5phGiLNUC&pg=PA195 ''Tourism Development'', pg. 195]</ref><!-- ref. no working ! -->

It became an international boundary with the independence of both countries from Yugoslavia in 1991. Since [[Croatia]]'s first multi-party elections in 1990, the [[Istrian identity|Istrian regionalist]] party [[Istrian Democratic Assembly]] (IDS-DDI, ''Istarski demokratski sabor'' or ''Dieta democratica istriana'') has consistently received a majority of the vote and maintained through the 1990s a position often contrary to the government in [[Zagreb]], led by the then nationalistic party [[Croatian Democratic Union]] (HDZ, ''Hrvatska demokratska zajednica''), with regards to decentralization in Croatia and certain facets of [[region]]al [[Autonomous entity|autonomy]].

However, that changed in 2000 when the IDS formed with five other parties a left-centre coalition government, led by the [[Social Democratic Party of Croatia]] (SDP, ''Socijaldemokratska Partija Hrvatske''). After the reformed HDZ won the Croatian parliamentary elections in late 2003 and formed a minority government, the IDS has cooperated with the state government on many projects, both local (in [[Istria County]]) and national. Since Slovenia's accession to the [[European Union]] and the [[Schengen Area]], customs and immigration checks have been abolished at the Italian-Slovenian border.
