After the Paris peace conference, the Banat, Bačka and Baranya province remained in place until the Vidovdan Constitution of 1921 which established the Kingdom of Serbs, Croats, and Slovenes as a unitary state and replaced in 1922 the 8 Pokrajinas (provinces) by 33 new administrative oblasts (counties) ruled from the center.
