1919, he issued the Amasya Circular, declaring the independence of the country was in danger. He resigned from the Ottoman Army on 8 July, and the Ottoman government issued a warrant for his arrest. But Kâzım Karabekir and other military commanders active in Eastern Anatolia followed Atatürk's lead and acknowledged him as their leader. On 4 September 1919, he assembled a congress in Sivas. Those who opposed the Allies in various provinces in Turkey issued a declaration named Misak-ı Millî ("National Pact"). Atatürk was appointed as the head of the executive committee of the Congress, which gave him the legitimacy he needed for his future politics. (see Sivas Congress) The last election to the Ottoman parliament held in December 1919 gave a sweeping majority to candidates of the "Association for Defence of Rights for Anatolia and Roumelia" (Anadolu ve Rumeli Müdafaa-i Hukuk Cemiyeti), headed by Atatürk, who himself remained in Angora, now known as Ankara.

On 23 April 1920, the GNA opened with Atatürk as the speaker; this act effectively created the situation of diarchy in the country. In May 1920, the power struggle between the two governments led to a death sentence in absentia for Mustafa Kemal by the Turkish courts-martial. Halide Edib (Adıvar) and Ali Fuat (Cebesoy) were also sentenced to death alongside Atatürk. On 10 August 1920, the Ottoman Grand Vizier Damat Ferid Pasha signed the Treaty of Sèvres, finalizing plans for the partitioning of the Ottoman Empire, including the regions that Turkish nationals viewed as their heartland.
