COPANO (co-pan'-yo), Chilian yoqui or cacique, born in the Malpocho valley in 1511; died early in 1548. He was chief of the Promancos, belonging to the Malpocho tribe. The caciques of neighboring regions made him their generalissimo to direct the war against the Spaniards, who had founded the City of Santiago in 1541. During 1541 Copano many times attacked the Spanish settlement, and caused heavy loss to the colonists. The next year, while Valdivia was absent from the City, the Indians, in great numbers, attacked it, burned the buildings, and forced the inhabitants to seek refuge in a fortress, which was also assaulted, and its defenders, under Alonso de Monroy, were compelled to go out and fight in the open field. The timely return of Valdivia prevented the destruction of the whole colony; and afterward Copano was defeated in three battles. During 1543-'4 he continued the hostilities against the conquerors, and then joined the Copiapinos, a tribe of northern Chili, and was proclaimed chief of all the allied forces. In 1545 he again attacked Alonso de Monroy at CopiapS, and only 5Ionroy and one of his officers escaped, all his other men perishing at the hands of the Indians. A treaty of peace made with Valdivia in 1546 did not continue long, and Copano destroyed the new City of La Serena in 1547. The celebrated chief was killed by some northern Indians that declined to be commanded by a stranger.
