Ghezo or Gezo was a King of the Kingdom of Dahomey, in presentday Benin, from 1818 until 1858. Ghezo replaced his brother Adandozan as king through a coup with the assistance of the Brazilian slave trader Francisco Flix de Sousa. He ruled over the kingdom during a tumultuous period, punctuated by the British blockade of the ports of Dahomey in order to stop the Atlantic slave trade. Ghezo finally ended Dahomeys tributary status to the Oyo empire but also dealt with significant domestic dissent and pressure from the British to end the slave trade. He promised to end the slave trade in 1852, but resumed slave efforts in 1857 and 1858. Ghezo died in 1858, possibly assassinated, and his son Glele became the new king.
Ghezo was a son born with the name Gakpe to King Agonglo and was a younger brother to Adandozan. When Agonglo died, there was a succession struggle between his sons before Adandozan was enthroned. An oral tradition which developed during Ghezos rule to largely erase Adandozan from official history say that Adandozan was merely named regent who refused to step down for Ghezo when he was old enough, but this is generally doubted by historians.
