A year before Columbus set sail for America, an African king was baptized and converted his kingdom into a Catholic nation that lasted nearly 370 years. King Nzinga a Nkuwu, ruler of Kongo, located in what is now northern Angola, decided to become a Christian not long after Portuguese mariners reached his shores in 1483. He was baptized in May 1491, became João I Nzinga a Nkuwu, and many of his noble followers followed suit. But when he died, two brothers contested the throne, one of whom, Afonso Mvemba a Nzinga, represented a Christian party and the other, Mpanzu a Kitama, opposed both Afonso and Christianity.
In the war the brothers fought, Afonso and the Christian party triumphed. Our only account of the war comes from the pen of Afonso, and therefore has an inevitable bias, but according to him, when the greatly superior forces of Mpanzu a Kitama were about to render a final assault against him in the square of Mbanza Kongo, the country’s capital, they suddenly broke and ran, giving Afonso a surprising victory. When Afonso interviewed the survivors of the battle, he learned that they had been frightened by the appearance of a heavenly force of five horsemen led by St. James the Greater.
Afonso was so moved by this miracle that when he designed a coat of arms of the country, he included five arms holding swords to represent the events of that day. The coat of arms that appeared on seals on letters, on royal regalia and in the throne room continued in use until King Pedro V swore vassalage to Portugal in 1859.
St. James’ Day, the 25th of July, was Kongo’s national holiday, as much in memory of the king and his victory as it was of the Portuguese saint. Every year the day was celebrated with feasting and military reviews, and people crowded in from the countryside to Mbanza Kongo and some of the provincial capitals to revel and to pay their taxes. Mbanza Kongo, which still exists as a medium-size provincial capital in northern Angola, continues to celebrate the day, now called a “cultural celebration,” which lasts from July 20 to 25.
Afonso did much more than create a coat of arms and a holiday, though. He devised the institutional framework for the growth of the Catholic Church into a lasting part of Kongo culture that reached from the capital, with its dozen churches, to remote country villages. His son, Henrique, became the first bishop of Kongo in 1518, and along with his father, Portuguese priests and educated Kongolese, created a marriage of African spirituality and Catholicism that would be the distinctive feature of its religion.
