1. Dahomey Amazons
Dahomey Amazons were an all-female military regiment that came into existence due to the high casualty rate of the male population in the Kingdom of Dahomey. The frequent warfare with neighboring states and the kingdom's obligation to give men as slaves to the Oyo Empire forced the kings of Dahomey to enlist women into the army. The Dahomey women soldiers often fought in the wars against Abeokuta.
