Who discovered the southwest?

The term "Southwest" in the context of the United States typically refers to a region characterized by diverse landscapes and cultures, primarily inhabited by Indigenous peoples long before European contact. European exploration began in the 16th century, with Spanish explorers like Francisco Vázquez de Coronado being among the first Europeans to document the region in the 1540s. However, the area was home to various Native American tribes, such as the Navajo and Hopi, long before these explorations.
