1946 Constantinopolitan Constituent Assembly election (The Sublime Porte)

The 1946 Constantinopolitan Constituent Assembly election was held on March 3, 1946 to elect the members of the Constituent Assembly, tasked with writing the constitution of the newly independent Republic of Constantinople. The electoral system that was decided on was proportional representation with a 5% threshold, leading to the creation of large parties via the union of political movements that had been active during the campaign of the January status referendum.

The election resulted in a dominant win for ethnic parties, as they obtained a combined 139 seats (or 70% of seats). The fragmentation of the political landscape among five major parties led to absence of many smaller parties from the body, leaving only three parties (two moderate parties and the Communist Party) into the Assembly. As a result of this deep fragmentation, negotiations on the text of the constitution proved to be long and difficult, lasting until August.
