William Winniett
In 1845, Winniett was appointed Governor of the Gold Coast which is now Ghana. In 1847, Winniett went to what is now Benin to try to convince the people there to end the slave trade. In 1848, Winniett used the West India Regiment to overthrow a king named Kwaku Akka. Winniett then tried to convince King Ghezo of the Dahomey to stop the Dahomey slave trade and ban human sacrifice.  Winniett also bought the Dutch fortresses on the West African coast so that he could end the Dutch slave trade.
