The royal family of Kongo chose Manuel Martins Kiditu as ruler in 1910, on the death of Pedro Mbemba, who had been Regent. Educated at Portuguese schools in Luanda and Huila, he was later described as "wise in the ways and customs of white men".
Manuel's reign over the reduced territory of the kingdom was ended by a revolt in 1914, at which point the Portuguese abolished the kingdom and assimilated the territory into the colony of Angola. By 1915, Manuel III also lost much of his claim to the throne, as the royal family recognized Álvaro XV Afonso Nzinga as ruler instead.
