Coronado, Francisco VÁZquez De

(born &circa; 1510, Salamanca, Spain—died Sept. 22, 1554, Mex.) Spanish explorer of the North American Southwest.

Appointed governor of Nueva Galicia in west-central Mexico, Coronado was sent north with a large force to locate and capture the legendary Seven Cities of Cíbola, reported to be fabulously wealthy. He was disillusioned to discover instead the Zuni pueblos of New Mexico and a seminomadic Indian tribe in Kansas. Though the treasure he sought eluded him, his explorers were the first Europeans to view the Grand Canyon, and he extended Spanish territory over huge areas of North America. His expedition's failure led to his indictment on his return to Mexico, but he was acquitted.
