📖 Biography

Njinga a Nkuwu was the fifth ManiKongo, or ruler, of the Kingdom of Kongo, reigning from around 1470, when Portuguese explorer Diogo Cão became the first European to reach the mouth of the Congo River in 1482, beginning sustained contact between Kongo and Portugal.

Hoping to benefit from Portuguese power, wealth and technology, Njinga a Nkuwu received a Portuguese mission of priests, workers and soldiers in 1490, and on 3 May 1491 he voluntarily converted to Christianity, taking the baptismal name João I.

The king's eldest son, Nzinga Mvemba, was baptised in the same period under the name Afonso, beginning a Christian dynasty; the conversion was entirely voluntary and unforced by military conquest, a rare occurrence in the history of European contact with Africa.

Njinga a Nkuwu abandoned Christianity around 1495, in part because the Catholic Church's insistence on monogamy conflicted with the political necessity of maintaining multiple marriages in Kongo's elective succession system, though the Christian faction within his court, led by his son Afonso, remained strong.

Upon Njinga a Nkuwu's death in 1506, a civil war broke out between his sons, and Afonso, representing the Christian faction, prevailed, going on to rule as Afonso I and cementing Kongo's transformation into a Catholic kingdom that would last for nearly 370 years.
