You will find in us an ally animated by a spirit of whole-hearted collaboration and ready to take a full share in all the efforts directed towards the realisation of the aims of the Treaty to which we are now acceding.

Speaking at the meeting of NATO foreign ministers in Lisbon, 20 February 1952
Straddling two continents, with a foot both in Europe and Asia, Türkiye is a multi-faceted country with a rich cultural heritage. Land of trade, agriculture and tourism, this vast country is at a crossroads of civilisations, between countries of the Middle East, Eastern Europe, the Caucasus and Central Asia.
As the Cold War developed in the post-war era, dividing Europe into Eastern and Western blocs, Türkiye chose to side with Western Powers. It is this policy that led to its membership of the North Atlantic Treaty Organization on 18 February 1952. Since then, NATO has been the cornerstone of Türkiye’s defence and security policy.
Setting the scene
Mustafa Kemal Atatürk founded the Turkish Republic in 1923 and introduced vast reforms that led to the democratisation and modernisation of society – as early as 1934, women were granted the right to vote. Foreign policy was founded on the principle of "Peace at home, peace abroad" and sought to reinforce cooperation and regional security. For instance, Türkiye initiated the Balkan entente with Greece, Romania and Yugoslavia in 1934 and the Saadabad Pact of 1937 with Iran, Iraq and Afghanistan.
Troops leaving for Korea
Threatened on two fronts by forces of the Axis and the Soviet Union, Türkiye was non-belligerent during most of the Second World War. Once over, it joined Western democracies in standing up against Soviet expansion as the Cold War started to develop. Türkiye later benefited from the support of the Truman Doctrine (1947) and the Marshall Plan (1948) offered by the United States to deter communist influence and help with the economic reconstruction of post-war Europe. In 1950, Türkiye sent troops in support of the United Nations to defend South Korea from the North Korean incursion across the 38th parallel. As a result of growing threats to security in Europe, it joined NATO in 1952.
JOINING THE CLUB
As the Cold War gradually polarised international relations, putting the United States and the Soviet Union at loggerheads, Türkiye saw its membership of NATO both as a security guarantee and a way of reinforcing its Western identity. Seeking NATO membership was as much a political move as it was a military one. For NATO, Türkiye's capacity to provide land and sea bases, its strong military forces and its strategic importance on the south eastern flank of the Alliance, meant that the country would be a solid ally in the region. The Montreux Convention, signed on 20 July 1936, set the rules governing the passage of vessels of war through the Straits. Türkiye has implemented the Convention in full transparency and impartiality since then.
It was in Lisbon, Portugal, at the ninth meeting of the North Atlantic Council on 20 February 1952 that Türkiye was formally welcomed as one of NATO's first two new members, alongside Greece; two days prior, Türkiye had signed its Instruments of Accession.
