The Battle of Anchem (also Battle of Anchiem or Battle of Anchim) was a battle fought between two factions of the Royal family in the Ethiopian Empire (Mangista Ityop'p'ya). The battle was fought to determine who would rule the empire, Empress (Nigiste Negest) Zewditu or King (Negus) Tafari Makonnen. The Battle of Anchem is memorable because the pro-Zewditu forces were not openly supported by Empress Zewditu. The battle is also memorable for the use of both psychological warfare and aerial warfare by the pro-Tafari forces.
