Final answer:
Hernando de Soto was both a conqueror, through his participation in conquering the Inca and leading expeditions in the southeastern United States, and an explorer, by venturing into and documenting new territories during his quest for gold.
Step-by-step explanation:
Hernando de Soto was both a conqueror and an explorer in the efforts of Spain to expand its empire in the Americas. As a conquistador, de Soto participated in Pizarro's conquest of the Inca and later led his own expeditions to conquer and claim new lands for Spain in the southeastern part of what is now the United States. The drive for wealth, specifically gold, led him to explore vast regions, including Florida, Georgia, the Carolinas, Tennessee, Alabama, Mississippi, Arkansas, Oklahoma, Louisiana, and Texas.
In these explorations, although he did not find the anticipated riches, de Soto and his followers documented new territories, encountering and often clashing with indigenous populations, while inadvertently spreading European diseases that devastated native communities.
