Tohono O'odham Reservation, Southern Arizona. The Tohono O’odham (the name means “Desert People”) inhabited what is today southern Arizona and the northern state of Sonora in Mexico. The O’odham were there hundreds if not thousands of years before either Mexico or the U.S. existed as nations. Until recently they traveled freely to visit family and follow their traditional practices - this is becoming increasingly difficult with increasing militarization of the border and the new push to build a wall right through their lands. Although they are also negatively affected by the rising numbers of illegal migrants passing through their lands, they have vowed to oppose construction of the wall on tribal land, paving the way for potential mass resistance following the model of Standing Rock.
