The basic foreign policy of Turkey under Atatürk was one of friendship with all its neighbours and non-involvement in Great Power politics. Atatürk was essentially a realist. He repudiated adventurism and expansionism. What Turkey wanted was to accomplish its internal reconstruction in peace. The major stance of Atatürk's diplomacy was not only pacific, but was also clearly respectful of law. Since the Republic of Turkey came into existence, the main background of Turkish foreign policy had been friendship with the Soviets. Good relations with Russia guaranteed Turkey's continued security on its northeastern frontier and in the Black Sea. Following the Italian conquest of Ethiopia and basically on account of this fact a Turco-British rapprochement started to take shape since 1935. Close co-operation between Turkey and Britain during the Montreux Straits Conference further accelerated the pace. Another aspect of Turkish foreign policy was the Balkan Entente of 1934 to guard against aggression in the region. Turkey's part in the Saadabad Pact of 1937 had also been active and enthusiastic. Regaining of Turkish sovereignty over the Straits at the Montreux Conference and winning back of the district of Hatay were among the most important successes of the Turkish diplomacy under Atatürk's auspices.

Following his seizure of power in 1922, Mussolini began to pursue the policy of 'mare nostrum' of the ancient Romans. He had an eye on the Anatolian lands bordering the Mediterranean. Local symbol of the Italian menace was the Dodecanese Islands which were started to be fortified in 1934. Mussolini's speech of that year showed that Italy did not renounce its earlier designs on Turkish territory. Atatürk did not take Mussolini's claims seriously, but the danger Italy represented could not be ignored. During the Ethiopian crisis, Turkey supported the League of Nations' sanctions against Italy and advocated the principle of collective security. Facing Italian expansionism, Turkey requested the holding of an international conference in Montreux and succeeded to obtain the right of bringing back the Straits to full Turkish sovereignty. Turkey's distrust of Italy deepened in 1937 and 1938. Ankara disliked the policy of Rome-Berlin axis. It did not acquit Italy of designs in the eastern Mediterranean. Italian occupation of Albania in 1939 soon led to Turkey's signing of mutual assistance agreements with Britain and France. Italy sharply denounced the Turco-Anglo-French rapprochement. For Turkey, as an ally in the eastern Mediterranean, had the strength to tip the balance against Italy.
