The area that encompasses the present day southwestern United States was primarily occupied

Native Americans, Spanish, Mexicans, Anglo-Americans

Explanation:

The territory of the southwestern United States (present-day California, Arizona, New Mexico, Nevada and Texas) was controlled by various civilizations throughout history.

Initially, and like the entire American continent, this territory was controlled by various Amerindian tribes, encompassed within the Pueblo civilization, and later by various civilizations such as the Navajo and Apaches.

From the 1500s and 1600s the Spanish conquest of North America developed, through which these territories became part of the Viceroyalty of New Spain. Thus, the period of Spanish domination began, which has left as a legacy a large number of names of cities and states in Spanish language.

Towards the 1800s, with the independence of Mexico from Spain, these territories became part of that young nation, until after the Mexican-American war ended in 1848, these territories passed into American hands.
