After the end of World War I and the dissolution of Austria-Hungary, the province of Bosnia and Herzegovina, along with Glamoč, became a part of the State of Slovenes, Croats and Serbs and soon thereafter Kingdom of Serbs, Croats and Slovenes. After the Vidovdan Constitution of 1921 established new administrative divisions, the town became part Travnik County. The country changed its name to the Kingdom of Yugoslavia in 1929, and then Glamoč became part of a new administrative unit, Vrbas Banovina.
