Spanish explorer who, in a partnership formed with Spanish explorer Francisco Pizzaro (1470?-1541) in 1522, explored the Inca territories of Mexico for wealth. Almagro made exploratory trips into Columbia and was the first European to enter Chile by land. The rivalry of the conquistadors turned ugly for Almagro when Francisco Pizzaro's brother, Hernando (1475?-1578), had Almagro beheaded in July of 1538 after the latter was charged with rebellion against Spain.
