The Cvetković–Maček Agreement, also known simply as the Sporazum in English-language histories, was a political compromise on internal divisions in the Kingdom of Yugoslavia. It was settled on August 26, 1939, by Yugoslav prime minister Dragiša Cvetković and by Vladko Maček, a Croat politician. The agreement established the Banovina of Croatia, with boundaries drawn to include as many ethnic Croats as possible. This effectively created within unitary Yugoslavia an autonomous Croatian sub-state, a demand of Croat politicians since the 1918 founding of the Kingdom of Serbs, Croats and Slovenes (Yugoslavia). The Banovina later provided a model for eventual post-war constitutional arrangements in Federal Yugoslavia (1943–1945).

Prince Paul of Yugoslavia, also known as Paul Karađorđević, was prince regent of the Kingdom of Yugoslavia during the minority of King Peter II. Paul was a first cousin of Peter's father, Alexander I.
