The Pima are a group of Native Americans living in an area consisting of what is now central and southern Arizona, as well as northwestern Mexico in the states of Sonora and Chihuahua. Pima Indians, the indigenous people who lived in the area around Mission Tumacácori in the 17th century, referred to themselves simply as “People”. Such was the case in most technologically primitive cultures around the world that had little or no contact with other groups. In the Pima language, the word for “People” is “O’odham”. When the Spanish arrived at Tumacácori in the 1600’s, they referred to the O’odham who lived along the rivers as “Pima”. They called this most northern outpost of New Spain "Pimería Alta"; Land of the Upper Pimas. Those indigenous people they found living in the desert they called “Papago”. Papago is the Spanish word for “tepary-bean eaters”. By the late 20th century, the Papago got tired of being referred to as bean-eaters or beaners. They officially changed The People’s name to Tohono O’odham, meaning Desert People.
