The one-storey andesite building was designed by architect Salim Bey, at the request of Enver Pasha, as the headquarters of the Committee of Union and Progress. Construction began in 1915, under the supervision of Turkish Army Corps architect Hasip Bey. Before the building was finished, the Turkish Grand National Assembly decided use it, and its completion had to be hurried for the inaugural meeting.
Grand Opening
Thousands gathered in Ulus Square for the opening of the assembly on April 23, 1920, and Sinop representative Serif Bey, who as the oldest member had been chosen as President of the Assembly, made the first speech. Ankara representative Mustafa Kemal followed him. Mustafa Kemal was elected President of the Assembly at the second session of the Assembly held the following day and concluded his acceptance speech by stating, “There is no power above this Grand Assembly anymore...”
The building continued to serve as the headquarters of the Turkish Grand National Assembly throughout the War of Independence and many significant decisions were made here;
October 13, 1923: Establishment of Ankara as the Capital City of the Turkish Republic
October 29, 1923: Declaration of Republic and the election of Mustafa Kemal as first president
Atatürk stated, “The Grand National Assembly is the living symbol of the Turkish Nation's century’s old search for self determination and consciousness...” The building continued to house the assembly until October 15, 1924.
