Ndongo Kingdom (c. 1450-1671) was an Mbundu kingdom located in Angola, along the Kwanza River. The kingdom was ruled by 1576 and Benguela established in 1587.
Ndongo initially was involved in farming and the long distance salt trade. With the arrival of the Portuguese, by the 1550s, it became active in the slave trade. In 1576, the Portuguese attempted an invasion, to feed its lust for slaves and to exploit reported silver deposit. They met aggressive
opposition. Their army over time diminished and the remaining troops resorted to slave trading. The Portuguese organized gangs kidnapping anyone they found. Ndongo's population was decimated over time and the kingdom in ruins by 1668. Queen Anna Nzinga moved to the interior and founded the Matamba Kingdom.
Ndongo was ruled by the ngola. The ngola was chosen from the line of Ngola Kiluanje, elected by administrators (tendala, ngolambole) , or elected by sobas. The ngola resided in the capital next to the province he controlled. Traveling administrators in the provinces help retain political cohesion. The administrators were tendala and ngolamboe. Tendala dealt with issues concerning administration and judicial matters. Ngolambole dealt with military matters.
The Kingdom was comprised of provinces, divided into sub-regions controlled by sobas.
