When D. Barbara died, on March 24th, 1666, her husband, D. Antonio Carrasco Nzinga a mona, killed the legitimate heir, D. João Guterres Ngola kanini, and usurped the throne, but was himself slain in a battle against D. Francisco Guterres Ngola kanini, in 1680. The conqueror then attacked the allies of the Portuguese, robbed the pumbeiros, and beheaded the Jaga Kasanji (1682).[494] Luiz Lopez de Sequeira at once took the field against him with five hundred and thirty infantry, thirty-seven horse, and ten thousand _empacaceiros_, and defeated him at Katole, a place within three days of the Royal _kabasa_. The King himself lost his life, but so did the leader of the Portuguese[495] and Vasco de Mello da Cunha. João Antonio de Brito, who took the command after his leader’s death, remained encamped for thirty days on the site of the battle; and finding that the enemies did not return, retired to Mbaka; from which we may judge that the Portuguese, too, suffered heavy losses. D. Veronica (or Victoria) Guterres, the sister of the late King, sued for peace, which was readily granted. Fresh complications threatened in 1689, when the Queen was charged—falsely, it appears—with having stirred up the soba Kahenda to rebel against his Portuguese masters; but matters were arranged through the intervention of bishop D. João Franco de Oliveira. No further trouble seems to have occurred with the successors of Queen Nzinga until 1744, when the Queen[496] provoked a war by killing a white trader and robbing pumbeiros: the result of which was the capture of her capital by Bartholomeu Duarte de Sequeira, and the cession of the Kinalunga Islands to Portugal.[497] THE LAST OF THE KINGS OF NDONGO, 1671. We have seen that D. João de Souza Ngola ari had been installed as the first King of Ndongo, recognised by the Portuguese (see p. 164), about 1627, and had been succeeded by D. Filippe de Souza, who died in 1660, and by João II. The hope that this tributary would prove a staunch ally of the Portuguese was not to be realised, for immediately after the disastrous campaign against Sonyo (see p. 131), in 1670, D. João Ngola ari raised the standard of rebellion, and invaded the district of Mbaka. The Governor, Francisco de Tavora,[498] a future Viceroy of India, who on account of his youth (he was only 23 years of age) and supposed prudence had been nick-named _o menino prudente_, despatched his captain-major, Luiz Lopes de Sequeira, to reduce the rebel to obedience. Ngola ari met with a defeat on the river Luchilu, close to the Pedras of Pungu a ndongo, which were considered impregnable. Yet, on a dark night, on November 18th, 1671, Manuel Cortes, the leader of the _guerra preta_, surprised this rocky stronghold. The King himself was taken, and beheaded as a traitor. Thenceforth there was no further need for punitive expeditions on a large scale.[499] RELATIONS WITH KONGO.
