Arizona was home to numerous Indigenous peoples including the Navajo, Apache, Hopi, Tohono O’odham, and Yaqui. The Apache Wars (1849-1924) were the longest series of US military campaigns against Indigenous peoples, resulting in the displacement and confinement of Apache bands to reservations. The US military employed tactics of total war, destroying food supplies and forcing surrender through starvation.
Arizona was part of Mexico until the Treaty of Guadalupe Hidalgo (1848) and the Gadsden Purchase (1854) transferred the territory to the United States. Mexican and Indigenous land grants were systematically violated. The imposition of US property law dispossessed Mexican landholders and Indigenous communities who had lived on the land for generations.
The discovery of vast copper deposits in the late 19th century transformed Arizona into a colonial extractive economy. Copper mining corporations including Phelps Dodge and ASARCO exploited Indigenous and Mexican labor, paying minimal wages for dangerous work. Mining pollution devastated Indigenous lands and water sources.
In one of the most egregious violations of labor rights in US history, mining companies and vigilantes forcibly deported over 1,000 striking miners and their families from Bisbee, Arizona to New Mexico. The victims were mostly Mexican, Indigenous, and immigrant workers. No one was prosecuted for this mass kidnapping and human rights violation.
Arizona has become the epicenter of the US border militarization project. The construction of walls, surveillance infrastructure, and the deployment of militarized border patrol forces has transformed the US-Mexico border region into a militarized zone. Migrant deaths in the Arizona desert have numbered in the thousands since the 1990s.
Arizona is ground-zero for water conflicts in the American West. The diversion of the Colorado River for agriculture and urban development has devastated Indigenous communities, including the Navajo and Hualapai who lack access to clean water. The Central Arizona Project, one of the largest water infrastructure projects in history, was built on stolen Indigenous land and has exacerbated water inequality.
