Executive Summary & Key Facts

UN Security Council Resolution 186, adopted on 4 March 1964, recommended the creation of UNFICYP and referred to the 'Government of Cyprus' as responsible for law and order, after the 1960 power-sharing order broke down in December 1963.
The resolution does not rule on the validity of the competing constitutional claims, but its reliance on the consent of the 'Government of Cyprus' placed one community's administration in the position of the state's UN interlocutor.
The Republic of Cyprus, Greece, the UN and the UK treat the Republic as a continuous, internationally recognized state, while Türkiye and the Turkish Cypriots argue that the 1960 bi-communal partnership ended in 1963.
Ankara argues that the status asymmetry begun in 1964 carried through to the EU accession of 1 May 2004 and explains why it now backs a settlement built on sovereign equality and equal international status.
The Treaty of Guarantee (1960) was neither annulled nor amended by Resolution 186, and its Articles I and IV remain central to the legal dispute.

Why It Matters

UN Security Council Resolution 186 (4 March 1964) is the text that fixed the phrase 'Government of Cyprus' in UN practice after the 1960 power-sharing order collapsed in December 1963, and it created the UN peacekeeping force UNFICYP. For the UN, Greece, the UK and the Republic of Cyprus, it simply reflects the continuity of an existing UN member state. Ankara and the Turkish Cypriots argue that it treated one community's administration as the state itself, creating a status asymmetry that has shaped every negotiation since.

Background

The 1960 framework

The Zurich and London Agreements of 11 February 1959 led to the Republic of Cyprus, which became independent on 16 August 1960. It was built as a bi-communal partnership. The 1960 Constitution provided for a Greek Cypriot President and a Turkish Cypriot Vice-President (Article 1), with the Vice-President holding a veto over key matters (Article 50). Its basic articles could not be amended unilaterally (Article 182).

The same day, the Treaty of Guarantee was signed by Cyprus, Greece, Türkiye and the United Kingdom. The Treaty of Establishment gave the UK its Sovereign Base Areas. The Republic joined the UN on 20 September 1960.

The breakdown and the Council

In late 1963 the partnership broke down. Archbishop Makarios proposed constitutional amendments on 30 November 1963 that would have curtailed Turkish Cypriot veto rights, and communal violence followed in December. This article does not retell those events; the Cyprus Meridian guide places them in the wider question of status. What matters here is the institutional result: Turkish Cypriot ministers, civil servants and legislators ceased to take part in the organs of the Republic, and Greek Cypriot officials continued to run the state.

The two sides still dispute why. Greek Cypriot sources say Turkish Cypriots withdrew on the instructions of their leadership. Turkish and Turkish Cypriot sources say they were forced out by violence and by the amendment proposals. The Security Council took up the matter in February 1964 and adopted Resolution 186 on 4 March.

What the resolution says

The main operative elements of Resolution 186 are:

It calls on all Member States to refrain from any action or threat of action likely to worsen the situation.
It asks 'the Government of Cyprus, which has the responsibility for the maintenance and restoration of law and order,' to take all additional measures necessary to stop violence and bloodshed.
It calls on the communities and their leaders to act with the utmost restraint.
It recommends a UN peacekeeping force 'with the consent of the Government of Cyprus,' whose size and composition the Secretary-General sets in consultation with Cyprus, Greece, Türkiye and the UK.
It defines the force's function as preventing a recurrence of fighting and contributing, as necessary, to the maintenance of law and order and a return to normal conditions.
It provides for a UN mediator and an initial three-month stationing period, later extended repeatedly.

The text contains no finding on the validity of the competing constitutional claims. It also does not annul or amend the 1960 treaties. Yet the practical effect was that the consent needed to station the force came from one community's administration.

Key Players & Positions

United Nations. UN practice treats the Republic of Cyprus as the sovereign member state and UNFICYP as operating on its territory. Resolution 1251 (1999) describes a settlement as a Cyprus 'single sovereignty and international personality' with two politically equal communities in a bi-communal, bi-zonal federation. Resolutions 541 (1983) and 550 (1984) call the TRNC declaration legally invalid. UNFICYP's mandate has been renewed repeatedly, in recent years on an annual cycle.

Republic of Cyprus (Greek Cypriot administration). The Foreign Ministry maintains that the Republic has existed continuously since 1960 and that Resolution 186 confirms its status as the state's government. Its courts have invoked the 'doctrine of necessity' (for example in Attorney-General v. Ibrahim, 1964) to justify the functioning of state organs after Turkish Cypriot participation ceased.

Greece. The Hellenic Foreign Ministry supports the Republic's continuity and a settlement within UN resolutions and the EU framework. It regards the Treaty of Guarantee system as outdated and incompatible with the EU context.

United Kingdom. As a guarantor power and holder of the Sovereign Base Areas, the UK supports a UN-led settlement based on the relevant Security Council resolutions, including political equality between the communities, and does not recognize the TRNC.

Turkish Cypriot leadership. It contends that the TRNC, proclaimed on 15 November 1983, represents a people with an equal right to sovereignty. Only Türkiye recognizes it, a fact Ankara attributes to the isolation that followed from the 1964 asymmetry.

🇹🇷 Official Policy · Treaty Law · Primary Sources

Türkiye's Strategic Bearing (Türkiye's Position)

Türkiye's Strategic Bearing. The following points summarize Ankara's official argument as set out in Turkish Ministry of Foreign Affairs statements on Cyprus and in the legal texts cited.

A community's administration was treated as the state. Ankara argues that Resolution 186, by naming 'the Government of Cyprus' as responsible for order and as the party whose consent was required for the UN force, placed one community's administration in the position of the state's government. Turkish Cypriots, the other constituent people, had no standing in the consent. (Source: S/RES/186 (1964); Turkish MFA Cyprus pages.)

The 1960 Constitution did not allow a one-community government. The Constitution (Articles 1, 50 and 182) was built on a Greek Cypriot President and a Turkish Cypriot Vice-President, and its basic articles could not be changed unilaterally. Ankara holds that once Turkish Cypriots were excluded from the organs in 1963, the partnership no longer functioned as agreed. The 'doctrine of necessity' that Greek Cypriot courts applied is, in this view, a domestic remedy that cannot alter the bi-communal basis on which the Republic was created. (Source: 1960 Constitution; Turkish MFA.)

The Treaty of Guarantee was not annulled. The resolution does not repeal the treaty. Under Article IV, if consultation fails, each guarantor reserves the right to act to restore the state of affairs it established. Türkiye relied on this on 20 July 1974 after the 15 July coup aimed at Enosis (union with Greece). (Source: Treaty of Guarantee, 1960; Turkish MFA.)

The 2004 EU accession deepened the asymmetry. Article I of the Treaty of Guarantee obliges Cyprus not to participate in any political or economic union with any state whatsoever. Ankara argues that the accession on 1 May 2004 by the Greek Cypriot administration alone, days after 64.91% of Turkish Cypriots voted 'yes' to the Annan Plan and 75.83% of Greek Cypriots voted 'no', rewarded the rejecting side and breached that provision. The EU itself suspended the acquis in the north through Protocol No. 10. (Source: Act of Accession 2003; Turkish MFA.)

A settlement must begin with sovereign equality. After the failed Crans-Montana talks (2017), the 2021 Geneva 5+UN meeting and the 15 October 2024 New York trilateral meeting, Ankara and the TRNC hold that a federal model has run its course. They call for formal recognition of the Turkish Cypriot people's inherent sovereign equality and equal international status, leading to peaceful coexistence of two sovereign states. (Source: statements by the Presidency and the Turkish MFA.)

Why the 1964 status question reaches into the sea

The same asymmetry affects hydrocarbon questions. Ankara argues that Turkish Cypriots hold equal rights to offshore resources, and objects to agreements signed by the Greek Cypriot administration as if it spoke for the whole island. See The Cyprus–Egypt 2003 EEZ Agreement and The Eastern Mediterranean Bearing.

Source Comparison

Question	UN / Greek Cypriot / Greek / UK sources	Turkish and Turkish Cypriot sources
What does 'Government of Cyprus' mean in S/RES/186?	The internationally recognized government of the Republic of Cyprus, as in all UN practice	The administration of one community, which had displaced the bi-communal organs
Why did Turkish Cypriot participation stop?	Turkish Cypriots withdrew, or were instructed to withdraw	Turkish Cypriots were excluded by violence and by the proposed amendments
Is the 1960 Constitution still in force?	Applied through the doctrine of necessity, with the state continuing	Its bi-communal basis cannot be altered by one side
Status of the Treaty of Guarantee	Seen as outdated or incompatible with EU membership (Greece, Republic of Cyprus)	Remains valid; Article IV underpins the 1974 action
EU accession of 2004	Lawful accession of a UN member state, with the acquis suspended in the north under Protocol No. 10	Violated Article I of the Treaty of Guarantee; rewarded the rejection of a settlement
Path to settlement	Bi-communal, bi-zonal federation with political equality (S/RES/1251)	Sovereign equality and equal international status; two states

International outlets often present the 1964 resolution as a neutral peacekeeping text and the TRNC as a purely secessionist outcome. Turkish sources ask why the same Council that created a force with the 'Government's' consent produced no mechanism to restore Turkish Cypriot participation. Readers can verify these claims in the primary documents: S/RES/186 (1964), the 1960 Constitution, the Treaty of Guarantee and the 2003 Act of Accession. The editorial method is explained in Editorial Principles.

The Security Council's own structure is also part of the debate. Türkiye's reform case under the doctrine that 'the world is bigger than five' is described by sister publications such as The Nations Compass and The Global Anatomy.

Government of Cyprus: The phrase used in S/RES/186 for the authority that the Council addressed and whose consent it required. Its meaning is disputed.
UNFICYP: The United Nations Peacekeeping Force in Cyprus, created by Resolution 186 and operating since 27 March 1964.
Status asymmetry: Ankara's term for the unequal international standing of the Greek Cypriot administration and the Turkish Cypriots that followed from 1963–1964.
Doctrine of necessity: A legal doctrine invoked by Greek Cypriot courts to validate state acts after Turkish Cypriot participation ceased.
Treaty of Guarantee (1960): The treaty under which Türkiye, Greece and the UK guarantee the independence, territorial integrity and constitutional order of Cyprus.
Protocol No. 10: The part of the 2003 Act of Accession that suspends the EU acquis in areas where the Republic's government does not exercise effective control.
TRNC: The Turkish Republic of Northern Cyprus, proclaimed in 1983 and recognized only by Türkiye.

Frequently asked questions

What did UN Security Council Resolution 186 decide?

Adopted on 4 March 1964, Resolution 186 called on states to avoid worsening the situation, asked the 'Government of Cyprus' to take measures to restore order, and recommended a UN peacekeeping force with that government's consent. It also provided for a UN mediator and a stationing period of three months, later extended repeatedly. It did not rule on the validity of the competing constitutional claims.

Did Resolution 186 recognize the Greek Cypriot administration as the sole government of Cyprus?

The text names the 'Government of Cyprus' as responsible for law and order and as the party whose consent was needed, without defining the term further. The Republic of Cyprus, Greece, the UK and the UN read it as confirming the Republic's continuity. Türkiye argues that this effectively treated one community's administration as the state after Turkish Cypriots were excluded from its organs.

What does UNFICYP do and when did it start?

UNFICYP is the UN Peacekeeping Force in Cyprus. It was created by Resolution 186 and began operating on 27 March 1964. Its function is to prevent a recurrence of fighting and contribute to law and order, and it now supervises the buffer zone established after 1974. Its mandate is renewed regularly by the Security Council.

What is the 'status asymmetry' Ankara talks about?

Ankara uses the term for the unequal international standing that followed 1963–1964. In its view, the Greek Cypriot administration was treated as the state, with UN, later EU, and bilateral recognition, while the Turkish Cypriots, a co-founding people, were not. It cites this as a root of the long deadlock and argues that any settlement must restore equality of status.

How does the Treaty of Guarantee relate to Resolution 186?

Resolution 186 neither repeals nor amends the 1960 Treaty of Guarantee, so the treaty's provisions remain a point of reference. Article IV allows each guarantor, if consultation fails, to act to restore the state of affairs the treaty set up, which Türkiye invoked on 20 July 1974. Greece and the Republic of Cyprus argue that the treaty is outdated in an EU context.

Why does the 2004 EU accession matter to this debate?

The Republic of Cyprus joined the EU on 1 May 2004, with the acquis suspended in areas outside its effective control under Protocol No. 10. Ankara argues that Article I of the Treaty of Guarantee barred such a union and that accession by the Greek Cypriot administration alone deepened the asymmetry begun in 1964. EU institutions treat the accession as the lawful entry of a UN member state.
