After the war, Vranje was part of the Kingdom of Serbs, Croats and Slovenes in one of the 33 oblasts; in 1929, it became part of the Vardar Banovina. During World War II, Nazi German troops entered the town on 9 April 1941 and transferred it to Bulgarian administration on 22 April 1941. During Bulgarian occupation, 400 Serbs were shot and around 4,000 interned. Vranje was liberated by the Yugoslav Partisans on 7 September 1944.
