Independent Macedonia (1944)

The Independent State of Macedonia was a proposed puppet state of Nazi Germany during the Second World War in the territory of the Kingdom of Yugoslavia that had been occupied by the Tsardom of Bulgaria following the invasion of Yugoslavia in April 1941. When Soviet Union forces approached the borders of Bulgaria near the end of August 1944, Bulgaria declared neutrality and briefly sought to negotiate with the Western Allies.
