The sanjak of Alexandretta was awarded to Syria in 1920 and in 1936 became the subject of a complaint to the League of Nations by Turkey, which claimed that the privileges of the Turkish minority in the sanjak were being infringed. The sanjak was given autonomous status in 1937 by an agreement, arranged by the League, between France (then mandatory power in Syria) and Turkey. Rioting by Turks and Arabs resulted (1938) in the establishment of joint French and Turkish military control. In 1939, France transferred the sanjak to Turkey and it became Hatay province.

In May 1, 1920, Mustafa Kemal gave a speech in Turkish Grand National Assembly where he said: "One of our foremost principles is the fact that our nation' border will pass South of Alexandretta. In the East, this border stretches to include Mosul, Kirkuk and Sulaymaniyah. Those are our national borders."(4) Thus setting out a clear goal that in Hatay's case was ultimately achieved. Another example of the importance that Atatürk attached to Hatay was when on 15 March 1923 he told a young girl in Adana who had emotionally said: "Father of our nation, please save us" that: "Lands that have been Turkish for 40 centuries will not remain in the hands of the enemy."
