The Government of the Grand National Assembly (Turkish: Büyük Millet Meclisi Hükûmeti), commonly known as the Ankara Government (Turkish: Ankara Hükûmeti), was the name given to the provisional and revolutionary Turkish government based in Ankara during the Turkish War of Independence (1919–1923) and during the final years of the Ottoman Empire. It was led by the Turkish National Movement, as opposed to the crumbling Constantinople Government, which was led by the Ottoman Sultan.
