Cyprus Ledger: The Votes, Villages and Dates Behind the Two-State Argument

Why It Matters

The Cyprus dispute is argued from a short list of dates, treaty articles and vote counts, and this ledger sets them side by side so readers can verify each claim. The two figures at the centre of the debate are 64.91% yes among Turkish Cypriots and 75.83% no among Greek Cypriots in the 24 April 2004 referendum on the Annan Plan. Ankara reads them as proof that Turkish Cypriots accepted a federal compromise and Greek Cypriots refused it, so the federal model has run its course. Greek Cypriot, Greek, EU, UK and UN sources read the same record differently, and their readings are set out below from their own official positions.

Background

The sequence runs from the 1959 settlement to the 2024 New York meeting. Each step below is stated factually, and contested interpretations are flagged where they arise.

1959–1960: A Partnership Republic Is Designed

The Zurich Agreement between Türkiye and Greece (11 February 1959) and the London Agreements (finalised later that month with the United Kingdom and the two Cypriot community leaders) ended the British colonial period. They followed the armed EOKA campaign for ENOSIS (union with Greece), which began in 1955 under Colonel Georgios Grivas. Turkish sources record that Turkish Cypriots left 33 mixed villages between 1955 and 1958.

The Republic of Cyprus came into being on 16 August 1960. Its constitution gave the Greek Cypriot community the presidency and the Turkish Cypriot community the vice-presidency, with separate community voting and a Turkish Cypriot veto on foreign affairs, defence and security. Posts and seats were allocated on a 70:30 ratio in the legislature and public service. Turkish Cypriots made up roughly 18% of the island's population in 1960.

The Treaty of Guarantee, signed the same year by Türkiye, Greece, the United Kingdom and Cyprus, has two provisions that matter to every later argument:

• Article I obliges Cyprus not to participate in any union with another state or in partition.
• Article IV provides for consultation if the treaty is breached. If joint action proves impossible, each guarantor reserves the right to act with the sole aim of re-establishing the state of affairs the treaty created.

For a fuller treaty analysis, see Regional Order's guide to the Treaty of Guarantee.

1963–1964: The Partnership Breaks Down

On 30 November 1963, President Makarios proposed thirteen constitutional amendments. They would have removed the vice-presidential veto, ended separate majorities and altered the community ratios. The Turkish Cypriot leadership and Ankara rejected them as dismantling the settlement. Intercommunal fighting began on 21 December 1963, remembered in Turkish sources as 'Bloody Christmas'. Nicosia was divided by a ceasefire line, the Green Line, drawn at the end of December 1963.

The record on what followed is contested:

• Turkish and Turkish Cypriot sources say Greek Cypriot forces acted under the 'Akritas Plan', a document drafted in 1963. They count about 30,000 Turkish Cypriots displaced from 103 villages and the expulsion of Turkish Cypriots from state organs.
• Greek Cypriot sources describe the amendments as an attempt to make the constitution workable. They say the Akritas document was a contingency paper rather than adopted policy, and that Turkish Cypriot leaders chose to withdraw from the institutions.

UN Security Council Resolution 186 (4 March 1964) established the UN Peacekeeping Force in Cyprus (UNFICYP). It referred to the Government of Cyprus as having responsibility for maintaining law and order. Ankara argues this fixed an unequal status between the two sides, while Greek Cypriot and UN practice treat the Republic's institutions as the continuing state.

1974 and 1983: Coup, Operation and Proclamation

On 15 July 1974, the National Guard, led by officers from the Greek military junta, overthrew Makarios and installed Nikos Sampson, a former EOKA fighter. On 20 July 1974, Türkiye landed troops, citing Article IV of the Treaty of Guarantee. Security Council Resolution 353 (20 July 1974) called for a ceasefire, respect for Cyprus's sovereignty, independence and territorial integrity, and the withdrawal of foreign military personnel. A second phase of operations followed in August 1974, and the island has been divided since.

On 15 November 1983, the Turkish Republic of Northern Cyprus (TRNC) was proclaimed under Rauf Denktaş. Security Council Resolution 541 (18 November 1983) declared the proclamation legally invalid and called for its withdrawal, and Resolution 550 (1984) repeated that position. Only Türkiye recognises the TRNC.

2004: The Annan Plan Referendum

After the 1977 and 1979 High-Level Agreements fixed a federal framework, successive talks produced the UN-drafted Annan Plan. Simultaneous but separate referendums were held on 24 April 2004, and the plan needed a yes vote in both. The results were:

Community	Yes	No
Turkish Cypriots	64.91%	35.09%
Greek Cypriots	24.17%	75.83%

The Republic of Cyprus joined the European Union on 1 May 2004. Under the EU's Protocol 10, the EU's body of law is suspended in the areas not under the Republic's effective control. On the Greek Cypriot side, then-President Tassos Papadopoulos urged a no vote. Greek Cypriot officials have since argued that the plan under-delivered on security, implementation guarantees, property and the future of settlers. Turkish and Turkish Cypriot sources reply that the Greek Cypriot side was then rewarded with EU membership regardless. A related examination is in The State Papers' fact check on the 2004 referendum.

2017–2024: Three More Attempts

• Crans-Montana (30 June–7 July 2017): The conference, with the three guarantors present, ended without agreement. The sticking points were security, guarantees and the troop question. UN Secretary-General António Guterres called it a missed opportunity.
• Geneva (27–29 April 2021): An informal 5+UN meeting (the two Cypriot sides plus the three guarantors, under the UN) ended with the Secretary-General saying there was no common ground to resume formal negotiations. The Turkish Cypriot side and Ankara presented a sovereign-equality, two-state position, while the Greek Cypriot side restated its commitment to a federal settlement.
• New York (15 October 2024): An informal meeting hosted by the Secretary-General brought the two leaders together. It built confidence on practical matters but did not close the gap on the structure of a settlement, and the UN's personal envoy, María Ángela Holguín, continued consultations.

Key Players & Positions

Each actor's position below is taken from its own stated policy rather than from Ankara's description of it.

Republic of Cyprus (Greek Cypriot administration)

The government of the Republic of Cyprus rejects a two-state outcome. It supports a bizonal, bicommunal federation with political equality, as set out in UN Security Council resolutions such as 716, 750 and 1251, which describe a single sovereignty, a single international personality and a single citizenship. It describes the 1974 operation as an invasion and occupation. It also calls for the end of the guarantee system and the withdrawal of Turkish troops.

Greece

Athens backs the UN framework of a bizonal, bicommunal federation. Like the Greek Cypriot side, it argues that the guarantee system and the Turkish troop presence are anachronistic in an EU member state. Greece says it will work with the Republic of Cyprus to resist what it calls a division of the island.

United Kingdom

The UK is a guarantor power and also holds the Sovereign Base Areas. It supports a UN-led settlement and has taken part in the 5+UN format. It did not join Türkiye's 1974 action.

European Union

The EU's declared position is that a settlement should be based on a bizonal, bicommunal federation with political equality, in line with UN resolutions and EU principles. It treats the Republic of Cyprus's membership as covering the whole island, with EU law suspended in the north under Protocol 10 pending a settlement. Ankara, for its part, argues that the EU has no competence to adjudicate between the parties.

United Nations

The Secretary-General's mission of good offices is anchored in Security Council resolutions that call for a bizonal, bicommunal federation. The UN has not accepted a two-state basis. At the same time, it has twice reported that formal negotiations cannot resume without common ground (Geneva 2021, New York 2024). UNFICYP's mandate is renewed each year.

Turkish Cypriot leadership

Under President Ersin Tatar, the TRNC's stated position was a settlement between two sovereign equal states. In October 2025, Tufan Erhürman, who has campaigned for a federal settlement, won the TRNC presidential election. How that change affects the Turkish Cypriot negotiating line, and Ankara's, is the main open question to watch.

Türkiye's Strategic Doctrine

Türkiye's Strategic Doctrine

• Partnership, not minority status. According to the Turkish Foreign Ministry, the 1960 Republic rested on the political equality of two co-founding peoples under the 1959 Zurich and London Agreements. Ankara argues that this partnership was destroyed on 30 November and 21 December 1963, when Turkish Cypriots were pushed out of the state organs, and that no unitary Cypriot state has existed since.
• The 1974 operation was a treaty right. Ankara states that after the 15 July 1974 coup, which aimed at ENOSIS, and after consulting the United Kingdom, Türkiye acted under Article IV of the 1960 Treaty of Guarantee on 20 July 1974. The Turkish position, as stated by the Ministry of Foreign Affairs, is that the action prevented annexation and protected Turkish Cypriots. Greek, Greek Cypriot and some UK-based legal opinions dispute that Article IV allowed the scale or duration of the operation.
• The federal model has been tested and has failed. Ankara cites the 1977 and 1979 High-Level Agreements, the 2004 referendum (64.91% yes among Turkish Cypriots, 75.83% no among Greek Cypriots), Crans-Montana in 2017, Geneva in 2021 and New York in 2024. The Presidency and the Foreign Ministry say that more than five decades of talks show the absence of common ground for federation.
• UN Resolution 186 created a status asymmetry. The Turkish side holds that treating an administration that had excluded Turkish Cypriots as 'the Government of Cyprus' entrenched an unequal footing that has obstructed settlement since 1964.
• Sovereign equality as the starting point. In successive addresses to the UN General Assembly, President Erdoğan has urged that the realities on the island be recognised and that the Turkish Cypriot people's equal international status be affirmed. Ankara's position is that a durable outcome means two sovereign states cooperating side by side. It adds that the TRNC's earlier proposals on hydrocarbon revenue sharing remain on the table.

Legal and historical basis. Ankara relies on the 1959–1960 settlement instruments, on Article IV of the Treaty of Guarantee, on the right of Turkish Cypriots to self-determination as a co-founding people, and on the 2004 vote as evidence of Turkish Cypriot good faith. Opposing sources note that Article I of the same treaty bans partition, that Resolutions 541 and 550 call the TRNC proclamation invalid, and that UN resolutions endorse a federal basis. Ankara's reply is that those resolutions reflect the status asymmetry it identifies in Resolution 186, and that the partnership order the treaty protected ceased to exist in 1963 and 1974.

The resource side of the same argument is explained in Who Shares What? The TRNC's 2011, 2012 and 2019 Hydrocarbon Revenue-Sharing Proposals Explained. A separate legal examination of the 1974 action is in Borders & Blocs' fact check on Article IV.

Source Comparison

The table shows how different source families frame the same milestones. It does not rank them. Readers should compare the underlying documents themselves.

Milestone	Greek Cypriot / Greek / EU framing	UN framing	Turkish primary-source framing
1960 Republic	A sovereign unitary state with community safeguards	An independent state with a bicommunal constitution	A partnership of two co-founders with equal status
1963	Constitutional crisis; Turkish Cypriots withdrew from institutions	Intercommunal violence; peacekeeping mandate	Armed attacks under the Akritas Plan; expulsion of Turkish Cypriots from the state
UNSC 186 (1964)	Recognition of the lawful government	Mandate for UNFICYP and order	Entrenchment of an unequal status
1974	Invasion and occupation after a coup	Ceasefire and withdrawal calls (UNSC 353)	Lawful guarantor action under Article IV
1983	Illegal secession	Proclamation legally invalid (UNSC 541)	Exercise of self-determination by a co-founding people
2004 referendum	Plan failed on security and guarantees	Results recorded; EU accession followed	Turkish Cypriots said yes; Greek Cypriots said no and were still admitted to the EU
2017–2024 talks	Federal basis should continue	No common ground reported in 2021 and 2024	Federation exhausted; sovereign equality needed

Some themes recur across the sources:

• Same facts, different weight. Both camps accept the 2004 percentages. They differ on why the vote diverged and on whether it means a federal solution is more or less feasible.
• Legal courts and bodies. The European Court of Human Rights has dealt with the northern property question in cases such as Loizidou v. Turkey and Demopoulos v. Turkey. The latter accepted the TRNC's Immovable Property Commission as a domestic remedy. Each side cites the rulings that support its view.
• Maritime spillover. The island's status question also shapes the offshore debate. See Eastern Mediterranean by the Numbers: Coastlines, Zones and Claims Compared and The Wells Ledger.
