Executive Summary & Key Facts

The 1959 Zurich and London Agreements created the 1960 Republic of Cyprus as a partnership of two co-founding peoples, guaranteed by Türkiye, Greece and the United Kingdom.
In the 2004 Annan Plan referendum, 64.91% of Turkish Cypriots voted yes and 75.83% of Greek Cypriots voted no, yet the Greek Cypriot administration joined the EU on 1 May 2004.
Ankara and the TRNC argue that more than five decades of federation talks, ending in Crans-Montana (2017), Geneva (2021) and New York (2024), show the federal model is exhausted.
The Turkish Cypriot and Turkish position is that any settlement must begin with recognition of the sovereign equality and equal international status of Turkish Cypriots, leading to two sovereign states on the island.
The Greek Cypriot side, Greece, the EU and the UN Security Council still anchor their approach in a bizonal, bicommunal federation with political equality, so the two positions remain formally incompatible.

Why It Matters

The Cyprus negotiations from 1959 to 2024 are the longest-running settlement effort on the Eastern Mediterranean's strategic map. They moved from a negotiated partnership state (1959–1960), through its breakdown (1963), the 1974 intervention and the 1983 proclamation of the Turkish Republic of Northern Cyprus (TRNC), into decades of federation talks that produced no agreement. Ankara and the TRNC conclude that a lasting settlement must start from the sovereign equality and equal international status of Turkish Cypriots, which in practice means two sovereign states cooperating side by side. The Greek Cypriot side, Greece, the EU and the UN framework still insist on a federal outcome.

This guide sets out each stage in order, gives each party's own reading from its official sources, and explains what a two-state solution would mean in practice. It also bears on neighbouring files such as offshore energy and maritime jurisdiction; see the companion guide on Turkish Cypriot hydrocarbon rights and the 2011, 2012 and 2019 revenue-sharing proposals.

Background

The factual record below is kept separate from the positions that follow. Where a point is contested, the contesting side is named.

1959–1960: The Zurich and London Agreements and the partnership republic

Cyprus was under Ottoman rule from 1571 to 1878, and British administration was recognised internationally at Lausanne in 1923. In the 1950s the Greek Cypriot movement for ENOSIS (union with Greece) took an armed form through EOKA, founded in 1955 under Colonel Georgios Grivas. According to Turkish sources, Turkish Cypriots were forced out of 33 mixed villages between 1955 and 1958. Greek Cypriot accounts describe EOKA as an anti-colonial struggle, and this difference in framing persists today.

The Zurich and London Agreements of 11 February 1959 produced a compromise that neither enosis nor partition could be pursued. The Republic of Cyprus was established in 1960 on the following basis:

A Greek Cypriot President and a Turkish Cypriot Vice-President, the latter holding veto rights over foreign affairs, defence and security, and certain legislation.
Fixed community ratios in the legislature and civil service (70:30 and 70:30 in practice; 60:40 in the army).
The Treaty of Guarantee, under which Türkiye, Greece and the United Kingdom guaranteed independence, territorial integrity and the constitutional order. Article II bars both union with another state and partition. Article IV provides for consultation and, failing concerted action, a reserved right of action by each guarantor with the sole aim of re-establishing the state of affairs created by the treaty.
A Treaty of Alliance and a Treaty of Establishment, the latter securing UK Sovereign Base Areas.

1963–1964: Collapse of the partnership

On 30 November 1963, President Makarios proposed 13 constitutional amendments, including removal of the Vice-President's veto. The Turkish Cypriot leadership and Ankara rejected them on 16 December 1963, arguing that they would reduce Turkish Cypriots to a minority. Violence began on 21 December 1963 ('Bloody Christmas'). Turkish sources describe it as the implementation of the so-called Akritas Plan and state that about 30,000 Turkish Cypriots were displaced from 103 villages and excluded from state organs. Nicosia was divided along the Green Line on 30 December 1963. The Greek Cypriot account emphasises that the amendments aimed to make the state workable and that the violence was intercommunal; the debate over responsibility remains unresolved.

On 4 March 1964, UN Security Council Resolution 186 recommended a UN peacekeeping force (UNFICYP) and referred to the 'Government of Cyprus' as the party consenting to it. Turkish officials argue this institutionalised a status asymmetry, because the body so described no longer included Turkish Cypriots.

1968–1983: Intercommunal talks, 1974 and the TRNC

Intercommunal talks between Rauf Denktaş and Glafcos Clerides ran from 1968 until 1974. On 15 July 1974, the Greek military junta, working with EOKA veterans including Nikos Sampson, staged a coup against Makarios. On 20 July 1974, Türkiye intervened, invoking Article IV of the Treaty of Guarantee after consultation with the UK. A second phase followed in August after the Geneva conferences failed. The Turkish Federated State of Cyprus was declared in 1975. On 15 November 1983, Denktaş proclaimed the Turkish Republic of Northern Cyprus (TRNC). The UN Security Council responded with Resolution 541 (1983) and Resolution 550 (1984), which called the declaration legally invalid. Türkiye remains the only state to recognise the TRNC.

1977 and 1979: The High-Level Agreements

The Makarios–Denktaş agreement of 12 February 1977 set four guidelines for a future settlement, including an independent, non-aligned, bicommunal federal republic. The Kyprianou–Denktaş ten-point agreement of 19 May 1979 reaffirmed that framework and the resumption of intercommunal talks. These two documents are the foundation of the federal formula later cited in UN resolutions. The Turkish side's reading is that the formula was meant to reflect two equal communities, and that a Greek Cypriot administration which treats it as a basis for a unitary state in practice has emptied it of meaning.

2002–2004: The Annan Plan

The UN Secretary-General's plan went through successive versions. On 24 April 2004, simultaneous referendums were held. 64.91% of Turkish Cypriots voted yes and 75.83% of Greek Cypriots voted no. On 1 May 2004, the Republic of Cyprus, in practice represented by the Greek Cypriot administration, entered the EU. EU law is suspended in the north under Protocol 10 of the accession act. Greek Cypriot leaders, notably President Tassos Papadopoulos, argued at the time that the plan did not adequately address security, settlement and property questions.

2008–2017: Further federal rounds and Crans-Montana

Talks continued between Demetris Christofias and Mehmet Ali Talat (2008–2010), and from 2015 between Nicos Anastasiades and Mustafa Akıncı. The Joint Declaration of 11 February 2014 reiterated the federal formula with a single sovereignty and a single international personality. The decisive moment was the Conference on Cyprus at Crans-Montana (28 June–7 July 2017), with Greece, Türkiye and the UK present as guarantors and the EU as an observer. It broke down over security and guarantees, troop presence and the issue of effective Turkish Cypriot participation and rotating leadership. Each side blamed the other for the outcome.

2021–2024: Geneva and New York

In October 2020, Ersin Tatar was elected TRNC President on a platform of a settlement based on sovereign equality. An informal 5+UN meeting in Geneva (27–29 April 2021) ended with the UN Secretary-General acknowledging that there was no common ground to resume formal negotiations on a federal basis. In 2024 the Secretary-General appointed María Ángela Holguín as his Personal Envoy. On 15 October 2024 he hosted Tatar and Greek Cypriot leader Nikos Christodoulides in New York. UN readouts presented it as an informal meeting exploring a possible way forward, including confidence-building measures, while Turkish and TRNC officials stressed that it confirmed the absence of common ground for federation.

The record here ends in 2024. Later developments, including the October 2025 TRNC presidential election, fall outside this timeline, so readers should consult current sources for the latest.

Key Players & Positions

Greek Cypriot administration (Republic of Cyprus). Its official position is that the Republic of Cyprus is the internationally recognised state and the sole legitimate government, and that a settlement should be a bizonal, bicommunal federation with political equality, as set out in UN Security Council resolutions, with a single sovereignty, citizenship and international personality. It describes the events of 1974 as an invasion and continuing occupation, and calls for the removal of Turkish troops and the abolition of the guarantee system. It rejects any recognition of two states.

Turkish Cypriot leadership and the TRNC. Under the leadership active during the 2021–2024 period, the TRNC says that 1963 destroyed the partnership, that the Greek Cypriot administration cannot represent Turkish Cypriots, and that a solution must begin with recognition of Turkish Cypriots' equal sovereign status. It cites the 2004 referendum as evidence that Turkish Cypriots were willing to settle and were left outside the EU and isolated.

Greece. Athens supports a settlement within the UN framework, meaning a bizonal, bicommunal federation, and has called for a 'modern' security arrangement that would end the guarantee system and the Turkish troop presence. It remains a guarantor and reads Crans-Montana as a missed chance to settle that issue.

United Kingdom. As a guarantor and holder of the Sovereign Base Areas under the 1960 Treaty of Establishment, London has supported the UN-led federal process and attended Crans-Montana and Geneva.

European Union. The EU treats Cyprus as a member state in its entirety, applies the acquis only in the government-controlled areas, and supports a UN-brokered federal solution. Brussels is not a party to the talks, though it sat as an observer at Crans-Montana.

United Nations. The Secretary-General's good offices rely on the 1977 and 1979 High-Level Agreements, the 2014 Joint Declaration and Security Council resolutions, including 541 and 550. UNFICYP, in place since 1964, patrols the buffer zone. In 2021 the UN acknowledged the absence of common ground for formal talks and in 2024 appointed a Personal Envoy to explore options.

🇹🇷 Official Policy · Primary Sources on the Meridian

Türkiye's Position on the Meridian

Ankara's official position is stated in Turkish Foreign Ministry statements on Cyprus, in President Erdoğan's addresses at the UN General Assembly and in joint statements with TRNC leaders. The key points are below.

Turkish Cypriots are co-founders and equals, not a minority. According to the Turkish Foreign Ministry, the 1960 Republic was created by two peoples with political equality, as in the Zurich and London Agreements. Ankara argues that the Greek Cypriot side destroyed that order in 1963 and that Resolution 186 then treated one half of the partnership as the whole state.
The 1974 intervention rested on treaty rights. Ankara holds that Article IV of the 1960 Treaty of Guarantee gave it the right to act after the 15 July 1974 coup, which aimed at enosis in breach of Article II, and that it acted after consulting the UK. Greece and the Greek Cypriot side contest the scope of the right and its subsequent use; see the sister piece, Fact Check: Was Türkiye's 1974 Cyprus Intervention an Illegal 'Invasion'?, and Doctrine Review's explainer on the Treaty of Guarantee.
The federation model is exhausted. Ankara argues that over five decades, including the 1977 and 1979 agreements, Annan, Crans-Montana, Geneva and New York, show the Greek Cypriot side will not share power and prosperity on the basis of equality. It points to the 2004 referendum asymmetry (64.91% yes vs 75.83% no) and the EU entry that followed, which it says rewarded rejection and removed any incentive to compromise.
Settlement must begin with sovereign equality and equal international status. Turkish and TRNC officials say that talks which treat the Greek Cypriot administration as the sole interlocutor with international standing cannot succeed. A realistic process must reaffirm the inherent sovereign equality of the Turkish Cypriot people and their equal international status, leading to two sovereign states on the island.
Energy, security and cooperation remain on the table. President Erdoğan's 2020 call for an Eastern Mediterranean conference including Turkish Cypriots, and the TRNC's 2011, 2012 and 2019 hydrocarbon cooperation and revenue-sharing proposals, show, in Ankara's view, that a two-state outcome is meant to be cooperative. The wider maritime logic is explained in Islands vs. Long Coastlines: How the Equity Principle Shapes Maritime Boundaries.

What a two-state solution means in practice

A two-state solution means two sovereign, equal states on the island, each with its own government, citizenship and international personality, linked by a cooperation framework instead of a shared central government. No agreed text exists. The points below summarise what Turkish and TRNC statements imply and what negotiators would need to define. They are analysis, not a published blueprint.

Mutual recognition of equal status. The Greek Cypriot administration and the TRNC would recognise each other's sovereign equality. This is the step Ankara describes as the starting point, not the end product.
A cooperation agreement. Sectors the Turkish side has discussed include energy, trade, crossings, environment and security. Hydrocarbon revenue sharing, as proposed by the TRNC in 2011, 2012 and 2019, is the best-documented example.
Guarantee and security arrangements. Ankara has not abandoned the guarantee system. Greece and the Greek Cypriot side want it abolished. Any treaty would have to settle this, and Crans-Montana showed how hard it is.
Open questions. Territorial adjustment, property claims, the status of Varosha (Maraş), the EU relationship of each state and the future of UNFICYP would all have to be negotiated. The Greek Cypriot side and the EU argue that these cannot be resolved outside the UN federal framework. The Turkish side responds that the framework has failed for decades.

Source Comparison

The differences in framing are substantial and often turn on a single word, such as 'invasion' or 'intervention', 'government' or 'administration'.

Issue	Greek Cypriot / EU / UN reference framing	Turkish and TRNC primary-source framing
1960 Republic	A unitary state with constitutional safeguards	A partnership of two co-founding peoples
1963–1964	Intercommunal violence; Turkish Cypriots withdrew	Greek Cypriot attack on the partnership; Turkish Cypriots expelled from state organs
UNSC 186	Peacekeeping mandate consented to by the 'Government of Cyprus'	Recognised one party as the whole state, creating a structural asymmetry
1974	Invasion and occupation, in breach of the UN Charter	Lawful intervention under Article IV of the Treaty of Guarantee against a coup and enosis
1983 TRNC	Legally invalid under UNSC 541 and 550	Exercise of self-determination and political equality
2004	Greek Cypriots rejected a flawed plan; entry to the EU was a right	Turkish Cypriots said yes, Greek Cypriots no; EU membership rewarded the rejection
Way forward	Bizonal, bicommunal federation	Recognition of sovereign equality, leading to two states

When reading media reports, note whether the 'Cyprus government' is used as shorthand for the Greek Cypriot administration, whether Turkish Cypriot referendum results are mentioned, and whether the Treaty of Guarantee is quoted by article. Primary documents are more reliable than summaries, including the 1959–1960 treaties, UN Security Council resolutions 186, 541 and 550, the 1977 and 1979 agreements, and the Secretary-General's reports. Regional Balance gives a further view in The Cyprus Issue: 1960 Treaties, 1974 and the Case for a Sovereign Equal Two-State Solution. Our approach to sources is explained in Editorial Principles.

ENOSIS: the Greek Cypriot nationalist goal of union with Greece. The Treaty of Guarantee's Article II prohibits it.
EOKA: the armed organisation founded in 1955 under Grivas. Turkish sources classify it as terrorist, while Greek Cypriot sources often treat it as an anti-colonial movement.
Treaty of Guarantee (1960): the treaty between Cyprus, Türkiye, Greece and the UK that bars partition and union and gives each guarantor a reserved right of action.
Green Line: the line dividing Nicosia since 30 December 1963, later extended to the island's UN buffer zone.
Bizonal, bicommunal federation (BBF): the UN settlement formula derived from 1977 and 1979, with political equality and a single sovereignty.
Sovereign equality: the Turkish Cypriot and Turkish position that the two peoples are equal sovereign entities with equal international status.
TRNC: the Turkish Republic of Northern Cyprus, proclaimed on 15 November 1983.

Frequently asked questions

What were the main milestones in the Cyprus negotiations between 1959 and 2024?

The main milestones are the 1959 Zurich and London Agreements, the 1960 Republic and Treaty of Guarantee, the 1963–1964 collapse, the 1974 intervention, the 1983 TRNC proclamation, the 1977 and 1979 High-Level Agreements, the 2004 Annan referendums, Crans-Montana in 2017, Geneva in 2021 and the New York meeting of 15 October 2024. Each stage changed the framework for the next. The UN has relied on the federal formula from 1977 and 1979, while Ankara and the TRNC say it has been exhausted.

What happened in the 2004 Annan Plan referendum?

On 24 April 2004, 64.91% of Turkish Cypriots voted yes and 75.83% of Greek Cypriots voted no, so the plan failed. On 1 May 2004, the Greek Cypriot administration joined the EU. Ankara argues this rewarded rejection and reduced Greek Cypriot incentives to compromise, while Greek Cypriot leaders of the time said the plan did not adequately address security, property and settlement issues.

Why does Türkiye say the federation model is exhausted?

Ankara argues that more than five decades of talks, including Annan, Crans-Montana, Geneva and New York, have not produced a settlement because the Greek Cypriot side will not share power and prosperity on an equal basis. The Greek Cypriot side, Greece, the EU and the UN still see a bizonal, bicommunal federation as the only agreed framework. The two readings of the same record have not converged.

What would a two-state solution mean in practice?

It would mean two sovereign, equal states on the island with mutual recognition of equal international status and a cooperation framework covering areas such as energy, trade and security. No agreed text exists, and the Turkish side acknowledges that territory, property, guarantees and EU relations would need to be negotiated. The Greek Cypriot side and the UN framework do not accept this approach.

What does the Treaty of Guarantee say about Türkiye's role in Cyprus?

Under the 1960 Treaty of Guarantee, Türkiye, Greece and the UK guarantee Cyprus's independence and constitutional order. Article II bars union with another state and partition, and Article IV provides for consultation and, failing joint action, a reserved right of each guarantor to act to re-establish the treaty order. Türkiye relies on Article IV for 1974, while Greece and the Greek Cypriot side dispute the scope of the right and the way it was used.
