The Vidovdan Constitution was adopted on 28 June 1921 and established a centralised constitutional monarchy under the Karađorđević dynasty. Political disagreements developed over the authority of the central government, the position of the historic regions, and the distribution of power between Serbian, Croatian, Slovene, Bosnian, Montenegrin, and Macedonian political groups.

Croatian Peasant Party leader [[Stjepan Radić]] was shot in the National Assembly on 20 June 1928 and died on 8 August. King Alexander I suspended the constitution and established a royal dictatorship on 6 January 1929. The state was renamed the Kingdom of Yugoslavia on 3 October and reorganised into administrative provinces known as banovinas.<ref name="croatia-history"/>

Alexander I was assassinated in Marseille on 9 October 1934. A regency governed on behalf of the underage Peter II until a military coup removed the regency on 27 March 1941.
