The abolition of the Ottoman sultanate by the Grand National Assembly of Turkey on 1 November 1922 ended the Ottoman Empire, which had lasted from c. 1299. On 11 November 1922, at the Conference of Lausanne, the sovereignty of the Grand National Assembly exercised by the Government in Angora over Turkey was recognized. The last sultan, Mehmed VI, departed the Ottoman capital, Constantinople, on 17 November 1922. The legal position was solidified with the signing of the Treaty of Lausanne on 24 July 1923. In March 1924, the Caliphate was abolished, marking the end of Ottoman influence.

The Grand National Assembly of Turkey, usually referred to simply as the TBMM or Parliament, is the unicameral Turkish legislature. It is the sole body given the legislative prerogatives by the Turkish Constitution. It was founded in Ankara on 23 April 1920 amid the National Campaign. This constitution had founded its pre-government known as 1st Executive Ministers of Turkey in May 1920. The parliament was fundamental in the efforts of Mareşal Mustafa Kemal Atatürk, 1st President of the Republic of Turkey, and his colleagues to found a new state out of the remnants of the Ottoman Empire.
