How did king Afonso become catholic?

King Afonso I of Kongo, also known as Afonso I, became Catholic in the early 16th century after his exposure to Portuguese missionaries. He was influenced by their teachings and saw Christianity as a means to strengthen his reign and unify his people under a common faith. Afonso embraced Catholicism, promoting it throughout his kingdom and integrating it with local beliefs, which helped to solidify his power and foster relations with Portugal. His conversion marked a significant moment in the history of Christianity in Central Africa.
