Editing Cyprus problem (section)

===Peacemaking efforts, 1964–1974===
At the same time as it established a peacekeeping force, the Security Council also recommended that the Secretary-General, in consultation with the parties and the Guarantor Powers, designate a mediator to take charge of formal peacemaking efforts. [[U Thant]], then the UN Secretary-General, appointed [[Sakari Tuomioja]], a Finnish diplomat. While Tuomioja viewed the problem as essentially international in nature and saw ''[[enosis]]'' as the most logical course for a settlement, he rejected union on the grounds that it would be inappropriate for a UN official to propose a solution that would lead to the dissolution of a UN member state. The United States held a differing view. In early June, following another Turkish threat to intervene, Washington launched an independent initiative under [[Dean Acheson]], a former Secretary of State. In July he presented a plan to unite Cyprus with Greece. In return for accepting this, Turkey would receive a sovereign military base on the island. The Turkish Cypriots would also be given minority rights, which would be overseen by a resident international commissioner. [[Makarios III|Makarios]] rejected the proposal, arguing that giving Turkey territory would be a limitation on ''enosis'' and would give Ankara too strong a say in the island's affairs. A second version of the plan was presented that offered Turkey a 50-year lease on a base. This offer was rejected by the Greek Cypriots and by Turkey. After several further attempts to reach an agreement, the United States was eventually forced to give up its effort.

Following the sudden death of Ambassador Tuomioja in August, [[Galo Plaza]] was appointed Mediator. He viewed the problem in communal terms. In March 1965 he presented a report criticising both sides for their lack of commitment to reaching a settlement. While he understood the Greek Cypriot aspiration of ''enosis'', he believed that any attempt at union should be held in voluntary abeyance. Similarly, he considered that the Turkish Cypriots should refrain from demanding a federal solution to the problem. Although the Greek Cypriots eventually accepted the report, despite its opposition to immediate ''enosis'', Turkey and the Turkish Cypriots rejected the plan, calling on Plaza to resign on the grounds that he had exceeded his mandate by advancing specific proposals. He was simply meant to broker an agreement. But the Greek Cypriots made it clear that if Galo Plaza resigned they would refuse to accept a replacement. U Thant was left with no choice but to abandon the mediation effort. Instead he decided to make his Good Offices available to the two sides via resolution 186 of 4 March 1964 and a Mediator was appointed. In his Report (S/6253, A/6017, 26 March 1965), the Mediator, now rejected by the Turkish Cypriot community, Dr Gala Plaza, criticized the 1960 legal framework, and proposed major amendments which were rejected by Turkey and Turkish Cypriots.

The end of the mediation effort was effectively confirmed when, at the end of the year, Plaza resigned and was not replaced.

In March 1966, a more modest attempt at peacemaking was initiated under the auspices of Carlos Bernades, the Secretary-General's Special Representative for Cyprus. Instead of trying to develop formal proposals for the parties to bargain over, he aimed to encourage the two sides agree to settlement through direct dialogue. However, ongoing political chaos in Greece prevented any substantive discussions from developing. The situation changed the following year.

On 21 April 1967, a [[Greek military junta of 1967–1974|coup d'état in Greece brought to power a military administration]]. Just months later, in November 1967, Cyprus witnessed its most severe bout of intercommunal fighting since 1964. Responding to a major attack on Turkish Cypriot villages in the south of the island, which left 27 dead, Turkey bombed Greek Cypriot forces and appeared to be readying itself for an intervention. Greece was forced to capitulate. Following international intervention, Greece agreed to recall General [[George Grivas]], the Commander of the Greek [[Cypriot National Guard]] and former EOKA leader, and reduce its forces on the island.<ref>{{cite journal | last=Coşkun| first=Yasin | title=The Cyprus Crisis of 1967 and The British-Turkish Policies | journal=Türk Dünyası İncelemeleri Dergisi| volume=18 | issue=2 | year=2018| doi=10.32449/egetdid.471803 | pages=377–398| doi-broken-date=1 November 2024 | language=tr}}</ref> Capitalising on the weakness of the Greek Cypriots, the Turkish Cypriots proclaimed their own provisional administration on 28 December 1967. Makarios immediately declared the new administration illegal. Nevertheless, a major change had occurred. The Archbishop, along with most other Greek Cypriots, began to accept that the Turkish Cypriots would have to have some degree of political autonomy. It was also realised that unification of Greece and Cyprus was unachievable under the prevailing circumstances.

In May 1968, intercommunal talks began between the two sides<ref>{{cite journal | last=CoşKun | first=Yasin | title=The Beginning of a New Era in the Cyprus Problem after the 1967 Crisis: The Inter-Communal Talks | journal=History Studies: International Journal of History | volume=10 | issue=9 |year=2018| doi=10.9737/hist.2018.675 | pages=55–84| doi-access=free }}</ref> under the auspices of the Good Offices of the UN Secretary-General. Unusually, the talks were not held between President Makarios and Vice-president Kucuk. Instead they were conducted by the presidents of the communal chambers, [[Glafcos Clerides]] and [[Rauf Denktaş]]. Again, little progress was made. During the first round of talks, which lasted until August 1968, the Turkish Cypriots were prepared to make several concessions regarding constitutional matters, but Makarios refused to grant them greater autonomy in return. The second round of talks, which focused on local government, was equally unsuccessful. In December 1969 a third round of discussion started. This time they focused on constitutional issues. Yet again there was little progress and when they ended in September 1970 the Secretary-General blamed both sides for the lack of movement. A fourth and final round of intercommunal talks also focused on constitutional issues, but again failed to make much headway before they were forced to a halt in 1974.
