Catholic Church in Kongo

The Catholic Church arrived in the Kingdom of Kongo shortly after the first Portuguese explorers reached its shores in 1483. Portuguese left several of their own number and kidnapped a group of Kongo including at least one nobleman, Kala ka Mfusu, taking them to Portugal where they stayed a year, learned Portuguese and were converted to Christianity. The group was returned to Kongo in 1485 and Kala ka Mfusu led a royal mission from Kongo's manikongo, Nzinga a Nkuwu to Portugal. Following their arrival in late 1486 the embassy stayed nearly four years in Lisbon with the monks of Saint John the Baptist. There they studied Christianity and Portuguese with Vicente dos Anjos (who also learned to speak Kikongo), and began the start of a Kongolese version of Christianity.

The mission returned to Kongo in early 1491, although Kala ka Mfusu died on the return trip. The provincial ruler of Soyo on the Atlantic coast received them and was the first to be baptized. They moved to the royal capital in April and May and Manikongo Nzinga a Nkuwu was baptized on 3 May 1491, taking the name João in honor of the Portuguese king, (João II). Many of his officials and nobles were subsequently baptized. While initially reluctant to allow the baptism of women, his wife, Nzinga a Nlaza, protested and eventually won him over; she was subsequently baptized as Queen Leonor of Kongo and became a champion of the church, paying expenses from her own income.

Further missionaries arrived at the court of Nzinga a Nkuwu, beginning in 1508 and a good number also accompanied his son Afonso Mvemba a Nzinga to his provincial post of Nsundi. Afonso, in turn became a great champion of the faith, even though, according to Afonso's subsequent account of the events, his father cooled in the faith and many of the Kongolese who had been baptized turned away.
