DUARTE COELHO, Pereira (dooar'tecoel'lo), Portuguese nobleman, died 7 August 1554. King Juan III., of Portugal, bestowed on Duarte one of the first hereditary captainships of Brazil. When he was sailing along the coast of Africa adverse winds compelled him to put in at the Island of Itamaraca, where he fought the French, ascended the River lguarasu, and compelled the Portiguare Indians to leave their village, which he made the seat of his government. On 10 April 1534, the captainship of Pernambuco was added to his royal donations, and on 24 October his dominion was extended from San Francisco River to that of Iguarasu. In 1535 Duarte founded the City of Olinda, where he removed with his wife and other colonists. He was at first seriously annoyed by the warlike tribe of Catrete Indians, who declared war against him, and afterward by revolts of the colonists, who were for the most part criminals and vagabonds, sent to the colony by the Portuguese government; but he soon put an end to all disturbances. The captainship of Pernambuco throve so well that in 1549, when the general government was established in Brazil, taking away the special privileges of grantees, those of Duarte were accepted. After conquering and settling more than 50.000 square miles of land, and founding several towns and cities, Duarte died, leaving his command to his wife, Brites de Alburquerque, his direct heir being absent in Portugal.
