Turkey (Türkiye)-U.S. Relations: Timeline and Brief Historical Context
This timeline tracks major from the beginning of close U.S.-Turkey (Türkiye) ties after World War II to the present. The information provides context for lawmakers assessing the tenor and trajectory of current bilateral relations on issues ranging from general strategic cooperation to timely regional concerns and domestic Turkish politics.
Early Cold War Partners (1945-1962)
Soviet pressure on the Turkish government to allow free passage through the Turkish straits (the Bosphorus and Dardanelles) and its territorial claims in eastern Anatolia threatened to precipitate hostilities between the two states, whose predecessors (the Russian and Ottoman Empires) had fought 12 wars over the preceding four centuries. Turkey turned to the United States for support. Mutual opposition to Soviet expansion would underpin Turkey- U.S. ties in the coming decades.
1945
Turkey declares war on Germany and Japan in February; becomes founding member of the United Nations
1946
In response to Soviet demands on Turkey for shared administration of the straits, the United States counters Soviet pressure by sending ships to Turkish waters

Allies amid Challenges (1963-1978)
U.S.-Turkey relations were particularly challenged by Turkey’s frequent clashes with fellow NATO member Greece over the ethnically divided island of Cyprus. Anti- Americanism grew as Turks increasingly debated the benefits and drawbacks of the bilateral relationship.
1964 Letter from President Lyndon Johnson to Turkish Prime Minister Ismet Inonu communicates U.S. opposition to
Turkish intervention in Cyprus after ethnic Greek- Turkish power sharing breaks down

1974 Turkey, using U.S.-supplied equipment, occupies the northern third of the island of Cyprus (an occupation that has continued to the present) on behalf of Turkish Cypriot minority, following a coup that installed a more pro-Greek government on the island
1975 Congress freezes aid and imposes arms embargo on Turkey for its actions in Cyprus
Turkey abrogates U.S. status of forces agreement; takes control of U.S. installations; U.S. forces performing NATO functions remain
1978 After intense lobbying by multiple presidential Administrations and several votes to partially lift the embargo, Congress fully repeals it
Renewed Military Cooperation (1980-1991)
The 1979 Soviet invasion of Afghanistan and Iran’s Islamic Revolution heightened the strategic importance of the Turkey-U.S. relationship for American interests in the broader Middle East.
