The moment
In 1491 the manikongo Nzinga a Nkuwu was baptised as João I, and under his son Afonso I the Kongo kingdom adopted Christianity as its religion, keeping much of its older belief alongside it. Kongo's church lasted for centuries. Enslaved Kongolese later carried their religion, including its Christian elements, across the Atlantic, where it became one of the sources of Haitian Vodou.
