Treaty of Guarantee (1960)


The Treaty of Guarantee is a treaty between Cyprus, Greece, Turkey and the United Kingdom that was promulgated in 1960.
Article I bans Cyprus from participating in any political union or economic union with any other state. Article II requires the other parties to guarantee the independence, territorial integrity and security of Cyprus. Article IV reserves the right of the guarantor powers to take action to re-establish the current state of affairs in Cyprus, a provision that was used as justification for the Turkish invasion of 1974. The treaty also allowed the United Kingdom to retain sovereignty over two military bases.
Article IV entitled these three guarantor powers to multilateral action among them or, as a last resort if no concerted action seemed possible, each guarantor to unilateral actions confined to restoring its status according to the treaty as a democratic, bicommunal, single, sovereign independent state:
Initially, a bicommunal independent state was at stake because of the July 1974 coup and several Turkish Cypriot enclaves being attacked at the onset of the coup. Those circumstances made Turkey claim the right to unilateral action, as provided by the treaty, by.
In the, Turkish forces invaded and held on to one third of the island, resulting in effective partition of the island and secession of the parts of the island under its military control. Hence, the second invasion is regarded as a violation of the treaty.
The treaty was concluded the same year that the Constitution of Cyprus was finalised, and the Zürich and London Agreement and the Treaty of Alliance between the Cyprus, Greece and Turkey were written.
