 In 1818, King Ghezo (reign 1818-1858) came to the throne by forcibly replacing his older brother Adandozan.Crucial in Ghezo's rise to power was the financial and military assistance of Francisco Félix de Sousa, a prominent Brazilian slave trader located in Whydah.As a result, Ghezo named de Sousa the "chacha" or viceroy of trade in Whydah providing him with significantly more power and money (the title "chacha" remains an important honorary position in Whydah to this day).
