Vardar Macedonia (Macedonian and Serbian: Вардарска Македонија, romanized: Vardarska Makedonija) is a historical term referring to the central part of the broader Macedonian region, roughly corresponding to present-day North Macedonia.
The name derives from the Vardar River and is primarily associated with the period of Serbian (1912–1918) and later Yugoslav rule (1918–1991).
[9] During World War I it was occupied by Bulgaria as part of the Military Inspection Area of Macedonia.
After the war the present-day Strumica and Novo Selo municipalities were broken away from Bulgaria and ceded to Yugoslavia.
During the Second World War, Bulgaria established two administrative districts in the region – Bitola and Skopje.
