Baptism of Nkuwu Nzinga

Date: May 3, 1491 • Location: Rome, Italy

Nkuwu Nzinga, the ruler of the Kingdom of Kongo, was baptised as João I by Portuguese missionaries.

The Kingdom of Kongo was a kingdom in Central Africa. It was located in present-day northern Angola, the western portion of the Democratic Republic of the Congo, southern Gabon and the Republic of the Congo. At its greatest extent it reached from the Atlantic Ocean in the west to the Kwango River in the east, and from the Congo River in the north to the Kwanza River in the south. The kingdom consisted of several core provinces ruled by the Manikongo, the Portuguese version of the Kongo title Mwene Kongo, meaning "lord or ruler of the Kongo kingdom", and its sphere of influence extended to neighbouring kingdoms, such as Ngoyo, Kakongo, Loango, Ndongo, and Matamba, the latter two located in what became Angola.
