King Diogo's successor, whose name is lost to history, was killed by the Portuguese, and replaced with a bastard son, who was more pliant to Tomista interests, Afonso II. The common people of Kongo were enraged at his enthronement, and responded with riots throughout the kingdom. Many Portuguese were killed, and the royal port of Mpinda was closed to the Portuguese, effectively ending the slave trade between Kongo and Portugal. Less than a year into this chaos, King Afonso II was murdered while attending mass, by his brother, the next manikongo, Bernardo I. King Bernardo allowed the boycott of Portuguese trade to continue, while quietly reestablishing relations with Lisbon. King Bernardo I was killed warring against the Yaka, in 1567. The next manikongo, Henrique I was drawn into a war in the eastern part of the country, where he was killed, leaving the government in the hands of his stepson Álvaro Nimi a Lukeni lua Mvemba. He was crowned as Álvaro I, "by common consent," according to some witnesses.
