World War II in Yugoslav Macedonia started with the Axis invasion of Yugoslavia in April 1941. Under the pressure of the Yugoslav Partisan movement, part of the Macedonian communists began in October 1941 a political and military campaign to resist the occupation of Vardar Macedonia. Officially, the area was called then Vardar Banovina, because the very name Macedonia was prohibited in the Kingdom of Yugoslavia. It was occupied mostly by Bulgarian, but also by German, Italian, and Albanian forces.

Macedonians are a nation and a South Slavic ethnic group native to the region of Macedonia in Southeast Europe. They speak Macedonian, a South Slavic language. The large majority of Macedonians identify as Eastern Orthodox Christians, who share a cultural and historical "Orthodox Byzantine–Slavic heritage" with their neighbours. About two-thirds of all ethnic Macedonians live in North Macedonia and there are also communities in a number of other countries.
