The constitution of 1921 was the first constitution that mentioned national sovereignty and proclaimed the first grand assembly as the true representative of the nation. It declared that elections would be held every other year and the newly elected parliament would convene in the first week of November. However, it was stated that the existing parliament would stay until the newly elected parliament could gather in Ankara. The political system that the constitution created was an example of the assembly government modelLegislative and Executive powers were vested in the Assembly and it controlled the ministers. The Assembly could remove ministers from their position. The Assembly enacted laws when needed and exercised its executive power over the cabinet (İcra Vekilleri Heyeti). While the Assembly had the right to abolish the cabinet, the cabinet did not have the same right to dissolve the Assembly. The Chairperson of the Assembly was the head of the cabinet. The constitution did not have any article regarding how to elect a president of the state but Mustafa Kemal, as the chairperson of the Assembly, acted as if he were the president. The judicial branch of the government wasn’t designated in the constitution (Eroğul, 2016, p. 236).
