What organized Turkish people around a common goal to save Anatolia from the occupations?
The Allied occupation of Anatolia was legitimized through the Treaty of Sevrés by sharing Anatolia among themselves. But their plan was just left on paper since a national struggle started in Anatolia under the leadership of Mustafa Kemal.
It was the Grand National Assembly (Büyük Millet Meclisi) called the Turkish Grand National Assembly (hereafter the TGNA) after March 1921 with its government served as the sole political entity defending the Turkish national interests in Anatolia and organized people around a common goal to save it from the occupations.
