# Is Cyprus Being Turned Into a 'Military Base'? Reading the 1960 Treaty of Alliance, the Treaty of Guarantee and the Constitution Against Today's Defence Build-Up

> **Summary:** The 1960 Treaty of Alliance, Treaty of Guarantee and Cyprus Constitution on troops and Article 129, read against today's defence build-up claims.

## Key Facts & Verified Findings

- The 1960 Treaty of Alliance, concluded by the Republic of Cyprus, Greece and Türkiye, provided for a tripartite headquarters and stationed Greek and Turkish contingents, commonly cited as 950 and 650 personnel respectively.
- Article I of the Treaty of Guarantee obliges the Republic of Cyprus not to take part in any political or economic union with any state and to prevent activity promoting union with another state or partition of the island.
- A letter from the TRNC's representative in New York, reported on 14 November 2026, is a claim by one party; its circulation as a UN document is not a UN finding on its content.
- Airspace sovereignty under Article 1 of the Chicago Convention is distinct from the Flight Information Region, which is an air navigation service area and not a sovereignty boundary.
- The Greek Cypriot side rejects the TRNC's allegations, and neither side's claims on spending, arms deals or airspace have been adjudicated by an independent body.

## Why It Matters

The 1960 Treaty of Alliance, the Treaty of Guarantee and the 1960 Constitution set the legal limits on Cyprus's armed forces, foreign alliances and guarantor role. A letter from the TRNC's representative in New York, reported on 14 November 2026, argues that the current defence build-up is turning the island into a military base. This article reads the texts first and then sets the claims against them.

## Background

The 1960 Treaty of Alliance, concluded by the Republic of Cyprus, Greece and Türkiye, was one of three instruments linked to the Republic's independence on 16 August 1960. The Zurich and London Agreements of 11 February 1959 had established the Republic as a bi-communal partnership state, with Greek Cypriots and Turkish Cypriots as its founding communities, and with Türkiye, Greece and the United Kingdom as Guarantor Powers.

### The Treaty of Alliance and stationed contingents

The Treaty of Alliance established a tripartite headquarters in Cyprus and provided for Greek and Turkish contingents to be stationed on the island. The figures commonly cited are 950 Greek and 650 Turkish personnel. This desk has not reproduced the article text here, so readers should confirm these numbers against the operative article in the treaty's official text before relying on them.

### Article 129 and the army under the Constitution

The 1960 Constitution contemplated a Cypriot army of 2,000 personnel, commonly described as divided on a 60 percent Greek Cypriot and 40 percent Turkish Cypriot basis, as Article 129 is usually summarised. The Constitution's wider architecture distributed power between the two communities, including a Turkish Cypriot Vice-President with a veto over specified decisions. Those safeguards were the core of the partnership model that the 1963 constitutional proposals sought to change.

### Treaty of Guarantee: Articles I, II and IV

Article I of the Treaty of Guarantee contains the undertaking that the Republic will not take part in any political or economic union with any state and will prevent activity aimed at promoting union with another state or partition of the island. Article II records the Guarantor Powers' undertaking to recognise and guarantee the Republic's independence, territorial integrity and security, and the state of affairs established by the Basic Articles of the Constitution. Article IV sets out consultation between the guarantors and, where joint or concerted action is not possible, a right of action with the sole aim of re-establishing that state of affairs. The [Treaty of Guarantee Article IV text explained](/treaty-of-guarantee-article-iv-read-line-by-line) and the [Treaty of Guarantee Article I partition union with any other state](/treaty-of-guarantee-article-i-partition-union-prohibition-read) guides set out the wording line by line.

### Treaty of Establishment and the Sovereign Base Areas

The Treaty of Establishment, a separate instrument, preserved the United Kingdom's Sovereign Base Areas (SBAs) at Akrotiri and Dhekelia. The SBAs were retained under that treaty and are not created by the Treaty of Alliance. Arms access or base upgrades agreed bilaterally since then are separate arrangements and are not the same legal category. The sister analysis on [US arms access and base upgrades at regionalobserver.com](https://regionalobserver.com/cyprus-us-arms-access-base-upgrades-and-1960-treaties-eastern-mediterranean-secu) covers those newer arrangements.

## Key Players & Positions

Answering the question of who holds which position requires separating each actor's stated position from the commentary about it. The table below lists the main actors and the sources to check.

- **Republic of Cyprus (Greek Cypriot administration):** The administration describes its defence cooperation with Greece and its procurement as exercises of its sovereign right to self-defence and as consistent with its treaty obligations. The exact wording should be taken from the Presidency, Ministry of Foreign Affairs and Ministry of Defence statements, which this desk has not quoted.
- **Greece:** Athens treats the Treaty of Alliance as a continuing bilateral and tripartite obligation and has described its presence as consistent with the 1960 framework. Its statements should be checked against its own foreign ministry publications.
- **United Kingdom:** London, as a Guarantor Power and the holder of the SBAs, refers to the Treaty of Establishment and the Treaty of Guarantee as the basis of its position.
- **European Union:** The EU supports a comprehensive settlement under UN auspices and has its own Cyprus-related positions in Council and Commission texts.
- **United States:** Washington supports a settlement under UN auspices and manages its own bilateral security arrangements with Nicosia, which are discussed in the [regionalobserver.com analysis](https://regionalobserver.com/cyprus-us-arms-access-base-upgrades-and-1960-treaties-eastern-mediterranean-secu).
- **TRNC letter (New York, November 2026):** As reported, the letter criticises Greek Cypriot defence spending, arms deals and exercises, and alleges airspace violations. Its own text is the primary document, and this desk has not been able to check the full text or its document symbol against a UN record.
- **Türkiye (Ministry of Foreign Affairs):** Ankara's Cyprus statements, which are summarised below, reject the position that the Greek Cypriot administration alone represents the island.

## Türkiye's Position

Ankara and the TRNC argue that the 1960 order was a bi-communal partnership with a guarantor system, and that the legal basis of that order is what should guide any defence arrangement on the island. The points below set out the position as stated, with the sources to check.

- **Ankara argues that the 1960 partnership was the basis of the Republic.** According to the Turkish Ministry of Foreign Affairs, the Republic was founded on the political equality and partnership of the two communities, and the 1963 changes removed that balance. Readers can check the Ministry's Cyprus statements at mfa.gov.tr.
- **Ankara argues that unilateral build-up breaches the spirit of Article I.** The argument is that arms build-up and alliance-style cooperation, when carried out by one community's administration, cut across the non-union and anti-partition undertaking and the original defence balance. The primary text is the Treaty of Guarantee, Article I.
- **Ankara argues that the build-up affects the security of Turkish Cypriots and the guarantors.** Turkish statements link defence developments on the island to the security of the Turkish Cypriot community, which Ankara treats as a co-founder of the Republic, and to the guarantor role under Article IV.
- **Ankara argues that the build-up hinders a settlement based on sovereign equality.** Turkish and TRNC statements hold that a settlement must begin from the equal status of the two peoples, and that militarisation undermines the conditions for talks. The TRNC letter itself is the primary source for this claim.
- **Legal basis.** Ankara's reading of the treaties relies on the Vienna Convention on the Law of Treaties, Articles 31 and 32, under which treaties are interpreted in good faith according to their ordinary meaning, context and object and purpose, with supplementary means where needed. The [Vienna Convention Articles 31–32 treaty interpretation explained](/vienna-convention-articles-31-32-how-treaties-are-interpreted-turkiye-disputes) guide sets out how that method applies here. Ankara's legal stance on guarantor action is discussed in the [Article IV guide](/treaty-of-guarantee-article-iv-read-line-by-line).

## Source Comparison

The main framings differ in tone and in what they treat as established. The table below separates what can be checked against texts from what remains contested.

| Source | Framing | Verifiable from text or primary record? | Status |
|---|---|---|---|
| Greek City Times (14 Nov 2026) | Describes the TRNC representative as representing an 'illegal occupation regime' and frames the letter as Türkiye attacking Cyprus | Partly: the letter's existence and circulation as reported; the characterisations are the outlet's own | Editorial framing, contested |
| Anadolu / A News (14 Nov 2026) | Reports the TRNC Prime Minister's statement condemning the flag burning and the chants at the anniversary protests | The statement is verifiable from the Prime Minister's office; the protest details are as reported | Reported statement, not adjudicated |
| UN letter (as reported) | Letter from the TRNC representative to the Secretary-General, circulated as a General Assembly and Security Council document | Not checked here; the document symbol and cover note need to be read from the UN record | Unverified by this desk |
| 1960 treaty texts | Set out contingents, guarantor undertakings and the constitutional framework | Yes, from the official texts; the contingent figures should be confirmed against the article text | Primary and verifiable |
| Cyprus Presidency and Ministry of Defence | State the defence cooperation rationale and procurement as exercises of sovereign rights | Verifiable from official statements, which should be read directly | Primary, a party's position |
| Turkish Ministry of Foreign Affairs | States the partnership and guarantor argument | Verifiable from ministry statements | Primary, a party's position |

### What the UN circulation does and does not mean

A letter becomes a UN document when a member state or observer asks for it to be circulated, and the UN then issues it under a document symbol. The TRNC is not a UN member, so any circulation would have been requested through a member state. Circulation is an administrative step and is not endorsement of the content. The UN has not endorsed the claims in the letter, and the desk should not be read as saying otherwise.

### Airspace claims

Article 1 of the Chicago Convention provides that every state has complete and exclusive sovereignty over the airspace above its territory. The Flight Information Region (FIR) is a block of airspace assigned by ICAO for air traffic services. An FIR boundary is an administrative and safety arrangement and does not determine sovereignty. The letter alleges airspace violations by Cypriot and Greek aircraft, and the Greek Cypriot side rejects those claims. These remain claims, not adjudicated findings, and no independent finding has been published here.

### Reading the press

The question for readers is which claims can be tested. The treaty texts, the Constitution and the UN record can be read directly. The spending figures, the arms deal details and the airspace incidents are contested and should not be treated as established on the basis of press reports alone. The [Fact Check on whether the Treaty of Guarantee can be ended without guarantors](/fact-check-can-treaty-of-guarantee-be-ended-without-guarantors-vienna-convention) shows how the same texts are used in other debates.

## Frequently Asked Questions

### What did the 1960 Treaty of Alliance provide for Cyprus, Greece and Türkiye?

The 1960 Treaty of Alliance, concluded by the Republic of Cyprus, Greece and Türkiye, provided for a tripartite headquarters in Cyprus and stationed Greek and Turkish contingents. The commonly cited figures are 950 Greek and 650 Turkish personnel, which readers should confirm against the operative article of the official text.

### What does Article I of the Treaty of Guarantee require of Cyprus?

Article I requires the Republic not to take part in any political or economic union with any state and to prevent activity promoting union with another state or partition of the island. Article II separately records the guarantors' undertaking to guarantee the Republic's independence, territorial integrity and security.

### Does a UN document circulated at a member's request mean the UN endorses its content?

No. A letter is circulated as a UN document when a member state or observer requests it, and the document symbol records that administrative step. Circulation is not endorsement, and the UN has not endorsed the claims in the TRNC letter reported in November 2026.

### Does Chicago Convention Article 1 settle the airspace allegations?

Article 1 of the Chicago Convention confirms that every state has complete and exclusive sovereignty over the airspace above its territory. The Flight Information Region is an ICAO-assigned air traffic service area and does not determine sovereignty, so the airspace allegations remain claims that the Greek Cypriot side rejects.

### Is the Sovereign Base Area arrangement the same as new bilateral arms access?

No. The UK Sovereign Base Areas at Akrotiri and Dhekelia are retained under the separate Treaty of Establishment. Newer bilateral arms access or base upgrades, such as those discussed in the regionalobserver.com analysis on US arrangements, are separate legal arrangements.
