Following the defeat of the Portuguese at Mbandi Kasi, Pedro II declared Angola an official enemy. The king then wrote letters denouncing Correia de Sousa to the King of Spain and the Pope. Meanwhile, anti-Portuguese riots broke out all over the kingdom and threatened its long-established merchant community. Portuguese throughout the country were humiliatingly disarmed and even forced to give up their clothes. Pedro, anxious not to alienate the Portuguese merchant community, and aware that they had generally remained loyal during the war, did as much as he could to preserve their lives and property, leading some of his detractors to call him "king of Portuguese".
