UN Security Council Resolution 186 (1964): Why Does Ankara Say It Created a Lasting Status Asymmetry in Cyprus?

Why It Matters

UN Security Council Resolution 186 of 4 March 1964 is the founding text of the UN's long involvement in Cyprus. It created the mandate for the UN Peacekeeping Force in Cyprus (UNFICYP) and called on the 'Government of Cyprus' to restore order. Ankara argues that by addressing the Greek Cypriot-led administration in that capacity, after the 1960 constitutional partnership had broken down, the resolution institutionalized an unequal status between the two communities. The Greek Cypriot side and the UN Secretariat read the same text as a routine reference to a UN member state's established government.

This brief reads the resolution in its historical context, sets out what it actually says, and presents each side's reading from its own sources.

Background

The 1960 settlement was built on partnership, not majority rule. The Zurich and London Agreements of 11 February 1959 led to the independent Republic of Cyprus, which was proclaimed in 1960. It rested on three treaties: the Treaty of Establishment, the Treaty of Alliance and the Treaty of Guarantee. Türkiye, Greece and the United Kingdom were the guarantor powers.

The constitution gave the two communities defined shares and protections:

• A Greek Cypriot President and a Turkish Cypriot Vice-President, each holding a separate veto over foreign affairs, defence and security.
• A 70:30 ratio in the House of Representatives and the civil service, and 60:40 in the army.
• Separate majorities for certain laws, such as tax and electoral legislation.
• 'Basic Articles' that Article 182 declared unamendable.

The period between independence and the crisis saw disputes over taxation, the army and separate municipalities, and these left the arrangement under strain. The sections below set out the sequence of events that followed.

Chronology, 1963–1964

The Greek Cypriot and Turkish Cypriot accounts of 1963 differ sharply. Greek Cypriot sources describe the 13 proposals as a good-faith attempt to remove obstacles to the state's functioning, and say Turkish Cypriot officials chose to withdraw from government. Turkish and Turkish Cypriot sources describe the proposals as an attempt to abolish the safeguards of the partnership. They also say Turkish Cypriots were pushed out of state organs, and they cite the 'Akritas Plan', a Greek Cypriot planning document, as evidence of premeditation. Ankara puts the number of Turkish Cypriots displaced from 103 villages at about 30,000.

What Resolution 186 actually says

The text is short. In substance, it:

• Notes that the situation is likely to threaten international peace and security.
• Calls on Member States to refrain from any action or threat of action that could worsen the situation, citing Article 2(4) of the UN Charter.
• Calls on the 'Government of Cyprus', which it describes as responsible for the maintenance and restoration of law and order, to take all additional measures needed to stop violence and bloodshed.
• Calls on the communities and their leaders to act with the utmost restraint.
• Recommends a UN peacekeeping force 'with the consent of the Government of Cyprus'. The force is to prevent a recurrence of fighting and contribute to law and order and a return to normal conditions.
• Asks the Secretary-General to fix the force's composition and size in consultation with Cyprus, Greece, Türkiye and the United Kingdom.
• Provides for a UN mediator and a three-month initial duration.

The resolution does not mention the 1963 amendment proposals, does not rule on who caused the breakdown and does not define the term 'Government of Cyprus'. That silence is the core of the dispute over its meaning.

Key Players & Positions

The main actors read the resolution in different ways.

• The UN Secretariat and Security Council: The UN treats the Republic of Cyprus as the sovereign state admitted in 1960, and peacekeeping practice generally depends on host-state consent. Later resolutions, including Resolution 541 (1983) and Resolution 550 (1984), reject the legal validity of the TRNC. Resolution 1251 (1999) says a settlement must be based on a state with 'a single sovereignty and international personality', comprising two politically equal communities in a bi-communal, bi-zonal federation.
• The Greek Cypriot administration: It maintains that it is the government of a sovereign UN member state and that Resolution 186 reflects the legal continuity of the Republic of Cyprus. It also holds that the 1960 constitution was disrupted in practice by Turkish Cypriot non-participation, and that Turkish intervention in 1974 violated Cypriot sovereignty.
• Greece: Athens supports the UN framework and the state's continuity. As a guarantor, it formally takes part in the diplomatic processes that followed.
• The United Kingdom: It is a guarantor power and administers the Sovereign Base Areas. It supports UN-led settlement efforts within the framework set by the Council.
• Turkish Cypriot leadership and the TRNC: They argue that the Turkish Cypriot community was a co-founding partner of the state, not a minority, and that it was displaced from state organs from December 1963.

Source Comparison

How a source frames Resolution 186 depends largely on whether it starts from the state's continuity or from the 1960 partnership.

Western and UN-based coverage usually treats the 1960 state as a continuous legal entity and frames 1974 as an occupation. Turkish primary sources treat 1963–1964 as the start of the crisis, and treat 1974 as an exercise of the right under Article IV of the Treaty of Guarantee. Readers should consult the actual text of the resolution and the Secretary-General's reports of the period, rather than summaries, for the precise wording. The site's Editorial Principles explain how we separate documented facts from positions.

The question also connects to the offshore dispute, since the same status question underlies the 2003 Egypt–Cyprus EEZ agreement, which Ankara contests on the grounds that Turkish Cypriots have equal rights over the island's resources.

Key Terms & Related Guides

• Government of Cyprus: The phrase used in Resolution 186 without a definition. The UN reads it as the established government of the member state, while Ankara reads it as one party to a broken partnership.
• UNFICYP: The UN Peacekeeping Force in Cyprus, created by the resolution and operational from 27 March 1964. It is still deployed, along the buffer zone.
• Green Line: The ceasefire line drawn across Nicosia on 30 December 1963, later extended into the UN buffer zone across the island.
• Treaty of Guarantee (1960): The treaty giving Türkiye, Greece and the United Kingdom guarantor rights. Article IV is the provision Ankara cites for its 1974 action.
• Akritas Plan: A Greek Cypriot planning document that Turkish sources cite as evidence of premeditated attacks. Greek Cypriot sources dispute this reading.
• Bi-communal, bi-zonal federation: The settlement model in UN resolutions since the 1970s, which Ankara and the TRNC say has been exhausted.
