Constitutional Assembly elections were held in the Kingdom of Serbs, Croats and Slovenes on 28 November 1920. The Democratic Party emerged as the largest faction, winning 92 of the 419 seats.[1] Deputies are elected by secret ballot, in a direct manner, by the electoral quotient system. The 1920 elections were the first democratic elections in the Kingdom of Serbs, Croats and Slovenes. Shortly after the election, the Communist Party of Yugoslavia was banned by the authorities.
Up until the elections a Provisional Assembly had existed of unelected delegates from each of the constituent regions of the country.
