Ceddo (1977)

In Senegal, sometime after the establishment of a European presence in the area but before the imposition of direct French colonial administration, the Ceddo ("commoners") try to preserve their traditional culture against the onslaught of Islam, Christianity, and the slave trade. When local king Demba War sides with the Muslims, the Ceddo abduct his daughter, Dior Yacine, to protest their forced conversion to Islam. After trying to rescue the princess, various heirs to the throne are killed, and Demba War is killed during the night. Eventually the kidnappers are killed and Dior Yacine is brought back to the village to confront the imam, just as all the villagers are being given Muslim names.
