Queen Njinga ruled in Matamba from 1631 until her death in 1663. During this time she integrated the country into her domains and thousands of her former subjects who had fled Portuguese attacks with her settled there. She made several wars against Kasanje especially in 1634-5. In 1639 she received a Portuguese peace mission which did not achieve a treaty, but did reestablish relations between her and the Portuguese. When the Dutch took over Luanda in 1641, Njinga immediately sent ambassadors to make an alliance with them. During these years, she moved her capital from Matamba to Kavanga, where she conducted operations against the Portuguese. Though Ndongo forces won a significant victory over the Portuguese at the Battle of Kombi in 1647, nearly forcing them to abandon the country and laying siege to their inland capital of Masangano, a Portuguese relief force led by Salvador de Sa in 1648 drove out the Dutch and forced Njinga to return to Matamba. Although she maintained a symbolic capital at Kindonga, an island in the Kwanza River where she and her predecessor had ruled, the real capital was at the town of Matamba (Santa Maria de Matamba). Njinga had been baptized as Ana de Sousa while in Luanda in 1622, and in 1654 she began peace overtures to Portugal.
