The political importance of the Brazilian presence in the region from the beginning of the nineteenth century can also be illustrated by the role played by Francisco Félix de Souza. This all-powerful Bahian slave trader became viceroy of Dahomey, with the title of Chachá, and contributed to the fall of Andadozan, king of Dahomey, who was deposed by his brother Guêzo, the future king, in 1818 (Costa e Silva, 2004). At this time, the majority of white people resident in the country were of Brazilian and Portuguese origin and were dedicated to trade - the slave trade, in particular. The human landscape of the region nevertheless changed profoundly with the return from Brazil of formerly enslaved people, owing largely to the deportation of hundreds of participants in the great revolt of 1835 in Bahia (Reis, 1987).
