The Dahomey Kingdom was known for its culture and traditions. Young boys were often apprenticed to older soldiers, and taught the kingdom's military customs until they were old enough to join the army. Dahomey was also famous for instituting an elite female soldier corps, called Ahosi, i.e. the king's wives, or Mino, "our mothers" in the Fon language Fongbe, and known by many Europeans as the Dahomean Amazons. This emphasis on military preparation and achievement earned Dahomey the nickname of "black Sparta" from European observers and 19th-century explorers such as Sir Richard Burton.
