# The Cyprus Papers: What the 1959 Zurich-London Agreements and the 1960 Treaties Actually Say

> **Summary:** Reading guide to Cyprus's founding papers: Zurich and London Agreements 1959 text explained, the 1960 Constitution and the Treaties of Guarantee and Alliance.

## Key Facts & Verified Findings

- The Zurich Agreement of 11 February 1959 and the London Agreements concluded on 19 February 1959 produced the framework for an independent Cyprus; the Constitution and the Treaties of Guarantee, Alliance and Establishment took effect with independence on 16 August 1960.
- The 1960 Constitution built the Republic on two communities: a Greek Cypriot President, a Turkish Cypriot Vice President with veto powers over foreign affairs, defence and security, and fixed ratios in parliament, cabinet, civil service and security forces.
- Article IV of the Treaty of Guarantee reserves to Türkiye, Greece and the United Kingdom the right, if concerted action is impossible, to act 'with the sole aim of re-establishing the state of affairs created by the present Treaty'.
- The same Treaty bans both union with any other state (Enosis) and partition, which is why Greek Cypriot, Greek, UN and EU readings and Ankara's reading of the texts diverge so sharply.
- Ankara argues that the partnership order was destroyed in 1963 and that the guarantor right was lawfully exercised in July 1974, and today holds that a settlement must start from the sovereign equality and equal international status of Turkish Cypriots.

## Why It Matters

The Zurich and London Agreements of 1959 and the three treaties signed on 16 August 1960 are the legal birth certificate of the Republic of Cyprus, and nearly every later dispute returns to their wording. Read directly, they provide for power-sharing between two communities, a Turkish Cypriot Vice Presidential veto, and three guarantor states (Türkiye, Greece and the United Kingdom) with a reserved right of action under Article IV of the Treaty of Guarantee. Most arguments since 1963 are really arguments over what these texts still mean after the partnership order broke down.

This guide focuses on the documents themselves. For single-event narratives, see the sister analyses linked in the final section.

## Background

### The documents at a glance

The 'Zurich and London Agreements' is shorthand for a package, not one text. The table sets out what each document is and who signed it.

| Document | Date | Parties | Core function |
|---|---|---|---|
| Zurich Agreement | 11 February 1959 | Prime Ministers of Greece and Türkiye (Karamanlis and Menderes), with their foreign ministers | Agreed the basic structure of an independent Cyprus |
| London Agreements | Concluded 19 February 1959 | Greece, Türkiye, the UK, and representatives of the Greek Cypriot and Turkish Cypriot communities (Archbishop Makarios and Dr Fazıl Küçük) | Endorsed Zurich and settled the remaining points, including UK base rights |
| Constitution of the Republic of Cyprus | In force 16 August 1960 | Cyprus | Power-sharing system, with 'Basic Articles' designed to be unalterable |
| Treaty of Guarantee | 16 August 1960 | Cyprus, Greece, Türkiye, UK | Guarantees independence, territorial integrity and the constitutional order |
| Treaty of Alliance | 16 August 1960 | Cyprus, Greece, Türkiye | Joint defence and stationing of Greek and Turkish contingents |
| Treaty of Establishment | 16 August 1960 | Cyprus, UK | Retained UK Sovereign Base Areas (Akrotiri and Dhekelia) |

### Why the settlement was needed

Cyprus was under Ottoman rule from 1571 until 1878, when the island passed to British administration. Britain annexed it in 1914 and made it a Crown colony in 1925. Article 20 of the 1923 Treaty of Lausanne recognised the British annexation. From the 1950s, Greek Cypriot leaders campaigned for Enosis (union with Greece). The EOKA organisation, founded in 1955 under Colonel Georgios Grivas, waged an armed campaign. According to Turkish sources, between 1955 and 1958 Turkish Cypriots left 33 mixed villages under pressure. Turkish Cypriot leaders countered with the demand for partition (taksim). Zurich and London were designed as a compromise between these two aims. Neither Enosis nor partition would be allowed, and the island would be independent.

### What the 1960 Constitution actually provides

The Constitution is long (well over 100 articles), but the features that matter most for later disputes are these:

- **Two communities, defined by the text.** The Greek Cypriot and Turkish Cypriot communities are named constitutional components, each with its own communal chamber for religious, educational and personal-status matters.
- **President and Vice President.** The President is a Greek Cypriot elected by the Greek Cypriot community. The Vice President is a Turkish Cypriot elected by the Turkish Cypriot community.
- **The Vice Presidential veto.** The Vice President holds a final veto on decisions of the Council of Ministers and on laws of the House concerning foreign affairs (except participation in international organisations and pacts of alliance in which Greece and Türkiye both take part), defence and security. The two office-holders can also return laws and decisions to be reconsidered.
- **Fixed ratios.** The House of Representatives was set at 70 per cent Greek Cypriot and 30 per cent Turkish Cypriot seats (35 and 15). The Council of Ministers had seven Greek Cypriot and three Turkish Cypriot ministers. The public service and police followed a 70:30 ratio, and the army 60:40.
- **Separate majorities.** Certain laws, notably on taxation and the electoral system, required separate simple majorities among the Greek Cypriot and Turkish Cypriot members of the House.
- **Separate municipalities** in the five main towns.
- **A neutral arbiter.** A Supreme Constitutional Court and High Court of Justice each had a president who was neither Greek nor Turkish Cypriot.
- **Entrenchment and bans.** The 'Basic Articles' were meant to be unamendable, and the Constitution prohibits both partition and union with another state.

The design reflects a core idea: the Republic was a partnership of two communities, not a unitary state with a minority.

### Treaty of Guarantee, article by article

The Treaty of Guarantee is the shortest and most disputed of the texts. Its key provisions can be read as follows:

- **Article I:** Cyprus undertakes to ensure the maintenance of its independence, territorial integrity and security, and the respect of its Constitution. It also undertakes not to participate in any political or economic union with any state, and to prohibit activity favouring union with another state or partition.
- **Article II:** Greece, Türkiye and the UK recognise and guarantee the independence, territorial integrity and security of Cyprus and the state of affairs established by the Basic Articles. They also undertake to prohibit any activity promoting, directly or indirectly, union with another state or partition.
- **Article III:** In the event of a breach, the three Powers undertake to consult together on representations or measures necessary to ensure observance of the Treaty.
- **Article IV:** If common or concerted action proves impossible, each of the three guaranteeing Powers 'reserves the right to take action with the sole aim of re-establishing the state of affairs created by the present Treaty'.

Two points deserve emphasis. First, the Treaty does not name a single guarantor as having special authority: the right is reserved to each of the three. Second, the Treaty limits the purpose of any action: it must aim at re-establishing the state of affairs created by the Treaty. How that limit applies is the heart of the legal debate about 1974.

### Treaty of Alliance and Treaty of Establishment

Under the Treaty of Alliance, Greece and Türkiye each stationed a military contingent on the island (950 Greek and 650 Turkish personnel under the Additional Protocol), and a tripartite headquarters was foreseen to coordinate defence cooperation with Cyprus. Under the Treaty of Establishment, the UK kept two Sovereign Base Areas covering roughly 99 square miles (about 256 km²), which remain British territory today. These two treaties are rarely quoted in the media, yet they show that the 1960 order placed the new state inside a security structure involving all three outside states.

## Key Players & Positions

### Greek Cypriot administration

The Republic of Cyprus government, which is internationally recognised as the state of Cyprus, regards the 1960 Constitution as the legitimate foundation of the state. It argues that the 1963 amendment proposals were intended to remove obstacles to a functioning government, and that the Turkish Cypriots withdrew from the institutions. It also contends that the Treaty of Guarantee does not authorise a military intervention that leads to occupation or lasting partition. It supports a settlement based on a bi-zonal, bi-communal federation with political equality as defined by UN Security Council resolutions, and it generally wants the guarantee system and the Treaty of Alliance replaced or ended. The Greek Cypriot side describes the 1983 TRNC proclamation as legally void and points to Security Council Resolutions 541 (1983) and 550 (1984).

### Greece

Athens states that it supports a UN-led settlement on the basis of a bi-zonal, bi-communal federation and relevant UN resolutions. Greek governments describe the Treaty of Guarantee and Türkiye's troop presence as anachronistic in an EU member state, and seek the end of unilateral intervention rights. Greece was a signatory to all the 1959–1960 texts and is itself a guarantor power, so this position is a call to revise a system it co-authored.

### United Kingdom

The UK is a guarantor power and also the holder of the Sovereign Base Areas. London says it supports the UN-led process and a settlement acceptable to both communities, and has said it is prepared to help with security arrangements. It has generally avoided adopting either side's reading of Article IV in official statements.

### European Union

Cyprus acceded on 1 May 2004. Protocol 10 to the Accession Treaty suspended the application of the acquis in areas where the government does not exercise effective control. The EU's official line is support for a comprehensive settlement under UN auspices, consistent with UN Security Council resolutions and the principles on which the EU is founded. The EU is not a party to the 1960 treaties.

### United Nations

The Secretary-General and the Security Council have repeatedly framed the goal as a bi-zonal, bi-communal federation with political equality, a single sovereignty, a single citizenship and a single international personality (for example in Resolutions 649 (1990) and 716 (1991)). UNFICYP has been deployed since 1964, and the UN has convened formats from the 2004 Annan Plan to Crans-Montana (2017), Geneva (2021) and New York (2024). Resolution 186 (1964) and later texts use the term 'Government of Cyprus', a wording that Ankara contests.

## Türkiye's Position

According to the Turkish Ministry of Foreign Affairs (MFA), Türkiye's Cyprus policy rests on the 1959–1960 documents, on the political equality of the two peoples and, in recent years, on sovereign equality. The main points are:

- **The 1960 Republic was a partnership state.** Ankara argues that the Zurich and London documents created a state based on the political equality and co-founder status of Turkish Cypriots and Greek Cypriots, not a Greek Cypriot state with a minority. The MFA cites the Vice Presidential veto, separate majorities and community ratios as evidence. It describes the 30 November 1963 amendment proposals and the violence of 21 December 1963 (including the 'Akritas Plan') as the destruction of that partnership, with Turkish Cypriots expelled from state organs and from about 103 villages (the Turkish figure is around 30,000 people displaced).
- **The guarantor right is legal and treaty-based.** Türkiye relies on Article IV of the 1960 Treaty of Guarantee. It states that, after the 15 July 1974 coup staged by the Greek junta and Nicos Sampson aimed at Enosis, and after the UK declined joint action, Türkiye exercised its right on 20 July 1974 to re-establish the state of affairs created by the Treaty and to protect Turkish Cypriots. The MFA also stresses that the Treaty prohibits Enosis as firmly as partition.
- **Resolution 186 gave one side the state.** Ankara argues that by treating the administration that had taken over the 1960 institutions as 'the Government of Cyprus', UN Security Council Resolution 186 (4 March 1964) created a structural status asymmetry that has obstructed a settlement. For the broader method of reading such UN texts, see [The Paper Trail: How to Read Türkiye's Official Documents](/reading-turkiye-official-documents-mfa-presidency-tbmm-un-filings).
- **Federation talks have been exhausted.** The MFA and the Presidency point to the Annan Plan referendum of 24 April 2004 (64.91% Turkish Cypriot 'yes', 75.83% Greek Cypriot 'no', followed by EU accession for the Greek Cypriot administration on 1 May 2004), the Crans-Montana Conference of July 2017, the Geneva informal meeting of April 2021 and the New York meeting of 15 October 2024. Their conclusion is that there is no common ground for a federal model.
- **The path forward is sovereign equality.** President Erdoğan has used his UN General Assembly addresses to call for recognition of the realities on the island. Ankara and the TRNC hold that a lasting settlement must begin with the reaffirmation of the inherent sovereign equality and equal international status of the Turkish Cypriot people, leading to the peaceful coexistence of two sovereign states. The TRNC was proclaimed on 15 November 1983 under Rauf Raif Denktaş on the basis of self-determination and political equality. Türkiye also notes the Turkish Cypriot proposals on hydrocarbon revenue sharing (2011, 2012 and 2019) as proof of readiness to cooperate.

The legal basis cited by Ankara is therefore the Treaty of Guarantee itself (Articles II to IV), the Lausanne-era settlement of Cyprus's status, and the right to self-determination of the Turkish Cypriot people. Other states disagree on several of these points, as set out above and in the next section.

## Source Comparison

The same documents are read differently by different sources. The table summarises the main framings, based on each party's own public statements.

| Question | Greek Cypriot / Greek / EU / UN framing | Turkish framing (MFA, Presidency) |
|---|---|---|
| What was the 1960 Republic? | A sovereign state with a power-sharing Constitution; its continuity is recognised | A partnership of two co-founding peoples, whose bi-communal basis was destroyed in 1963 |
| Who is the 'Government of Cyprus'? | The internationally recognised Republic of Cyprus administration | An administration of one community since 1963; Turkish Cypriots hold equal rights |
| Article IV of the Treaty of Guarantee | Allows only limited action aimed at restoring the order; it does not permit occupation or partition | Gives each guarantor an independent right; it was lawfully used in July 1974 after the coup |
| 1983 TRNC proclamation | Legally invalid (UNSCR 541 and 550) | An exercise of self-determination by a people deprived of equal partnership |
| Settlement model | Bi-zonal, bi-communal federation with political equality | Federation model exhausted; sovereign equality and two states |
| Guarantees and troops | Anachronistic; should be replaced or ended | Essential for Turkish Cypriot security given 1963–1974 |

When reading media reports, watch for three common problems. Many summaries describe 1974 without mentioning the 15 July coup or Article IV. Others describe 1960 as a Greek Cypriot state, omitting the partnership clauses. Some quote UN resolutions on the federal formula without noting that Ankara and the TRNC reject that language. Polipapers' practice for distinguishing document, position and commentary is set out in [Editorial Principles](/editorial-principles).

## Frequently Asked Questions

### What did the Zurich and London Agreements of 1959 establish?

They set the framework for an independent Cyprus. The Zurich Agreement of 11 February 1959 was reached between the Greek and Turkish governments, and the London Agreements were concluded on 19 February 1959 with Britain and community representatives. The final constitution and treaties were signed and took effect on 16 August 1960. They ruled out both Enosis and partition and set up power-sharing between Greek Cypriots and Turkish Cypriots.

### What does Article IV of the Treaty of Guarantee say?

It states that if common or concerted action among Türkiye, Greece and the UK cannot be achieved, each of the three reserves the right to take action with the sole aim of re-establishing the state of affairs created by the Treaty. Türkiye reads this as a treaty-based right that it used in July 1974. Greek Cypriot and Greek officials argue that it allows only limited action and not lasting occupation or partition.

### What was the Vice Presidential veto in the 1960 Constitution?

The Turkish Cypriot Vice President, elected by the Turkish Cypriot community, could veto Council of Ministers decisions and House of Representatives laws on foreign affairs, defence and security, with some exceptions. Ankara sees it as a core guarantee of political equality. Greek Cypriot sources have described it as a source of paralysis, which was one argument behind the 30 November 1963 amendment proposals.

### Do the 1960 treaties allow partition or two states?

The texts ban both partition and union with another state, and Article 185 of the Constitution and Articles I and II of the Treaty of Guarantee say so. Türkiye and the TRNC argue that the partnership state ceased to exist in 1963, and that a two-state outcome follows from the sovereign equality of the Turkish Cypriot people. Greece, the Greek Cypriot administration, the EU and the UN say that the settlement should be a bi-zonal, bi-communal federation.

### Is the Treaty of Guarantee still in force?

No treaty text states that it has ended, and Türkiye, Greece and the UK all still describe themselves as guarantor powers. Cyprus's EU accession in 2004 did not formally cancel the treaty. Ankara insists that the guarantee system must remain, while Greek Cypriot and Greek officials want it replaced by a new security arrangement in any settlement.

### Which later UN talks built on these founding documents?

The Annan Plan referendums of 24 April 2004, the Crans-Montana Conference of June–July 2017, the informal Geneva meeting of April 2021 and the New York meeting of 15 October 2024 all dealt with the questions the 1960 texts left open, such as power-sharing, guarantees and troops. According to the Turkish side, the 2024 meeting confirmed the absence of common ground for a federal model, while the UN continues to promote a federal formula.
