Balli Kombëtar
During the April War the Kingdom of Yugoslavia capitulated after 12 days of war against the Axis Powers. On April 20, Bulgaria occupied part of the Kingdom of Yugoslavia, including Preševo. The royal authoritarian dictatorship of Bulgaria occupied the area until September 7, 1944, when they handed the area over to Nazi Germany. The Albanian collaborationist regime along with Balli Kombëtar subsequently took over the area. In mid-November, the Partisans forced the Balli Kombëtar to retreat.
