Treaty of Sèvres
On 10 August 1920 Grand Vizier Damat Ferid Pasha signed the Treaty of Sèvres, which finalized the plans for the partitioning of Ottoman Empire including what Turkish nationals accepted as their heartland. Mustafa Kemal and his friends deemed the Treaty of Sèvres unacceptable, as it would spell the end of Turkish independence. The proposal for a British protectorate also rejected in the rest of Anatolia left to Turks by the Treaty of Sèvres. Kemal Insisted on complete independence and the safeguarding of the interests of the Turkish majority on Turkish soil. The acceptance of treaty and the following events weakened the legitimacy of the Sultan's government in Istanbul, and caused a shift of power in favour of the GNA in Ankara.
