When the Portuguese arrived in Kongo in 1483, the reigning king represented the Nimi kanda. This kanda was probably descended from Nimi a Nzima, father of the founder of Kongo. Divisions emerged within the kanda during succession disputes, for example, following the death of Afonso I in 1542, his son Pedro I and grandson Diogo I formed two opposed factions, that of Pedro was called the Kibala (court) faction, and the other, whose name is unknown that followed Diogo. Other elections in the sixteenth century probably also involved similar factions, though the details are unknown.
