In 1945, in the still existing Democratic Federal Yugoslavia, football once again began to be played nationally after a six-year hiatus due to World War II. The first post-war national tournament was a hastily organized week-long competition in cup format from September 3 until September 9, 1945. Each federal unit (socialist republic) within FPR Yugoslavia gathered a representative team. There were six teams representing Bosnia and Herzegovina, Croatia, Montenegro, Macedonia, Serbia and Slovenia, one team representing the autonomous region within Serbia, Vojvodina, and the final team being the Yugoslav People's Army (Jugoslovenska Narodna Armija, JNA) football team.
