Pedro IV
The defeated Antonians fled to Bula and sought the help of João II, who had still refused to recognize any king of Kongo other than himself. King João II marched his forces south to see what if anything could be gained at the expense of Pedro IV. On Saint Francis Day, October 4, the armies of João II and Pedro IV clashed within the Mbula territory. King Pedro IV was again victorious, and João II fled back to Lemba. King Pedro IV was so elated that he proclaimed St. Francis his savior and renamed his base São Francisco de Kibangu.
