NEGREIROS, Andre Vidal de (nay-gray'-eros), Brazilian patriot, born in Parahyba early in the 17th century ; died in Olinda, 10 January, 1681. In 1636 he successfully defended Bahia against Prince Maurice of Nassau (q. v.), and, after the capture of that place by the Dutch in 1638, he again expelled them. After the re-establishment of Portuguese independence in 1640, when the Dutch were not willing to surrender their conquests to the Portuguese, with whom the states-general had concluded a treaty of peace, Negreiros left for Pernambuco in 1644 to incite an insurrection, which began on 13 June. He openly took the direction of the patriot forces, and after repeated victories shut up the invaders in their fortified posts. But the Portuguese government did not aid the patriots, and they were forced to resort to guerilla warfare. In 1646 Negreiros was called to the province of Rio Grande, and in a short time vanquished the Dutch there and in Parahyba, winning the two battles of Guarapes in 1648 and 1649. At last the Dutch held only the fortress of Reeife, and in 1654 Negreiros attacked them there, and forced the commander to sign on 26 January the capitulation of Campinha de Taborda, by which he evacuated the city of Recife and the provinces of Hamaraca, Rio Grande, and Parahvba. As the principal cause of this triumph, Negreiros was commissioned to carry the notice of the expulsion of the Dutch to Portugal, and King John IV. made him a grandee and governor of Maranhao. Later he was governor-general of Angola, where he won the victory of Anabouillo, but returned after a few years to his native country.
