Yuma War
The Yuma War was the name given to a series of United States military operations conducted in southern California and what is today southwestern Arizona from 1850 to 1853. The Yumans were the primary opponent of the United States Army, though engagements were fought between the Americans and other native groups in the region. Conflict generally took the form of guerrilla warfare, and, over the course of three years, the army engaged in pursuing unfriendly natives, protecting American settlers crossing the Colorado River and preventing conflict between the native tribes. A peace treaty in summer of 1853 was signed, ending hostilities between the Yuma and the United States, but it sparked a short war between the Yuma and the Cocopah. During the conflict, the historic Fort Yuma was constructed and became an important outpost on the frontier.
Native Americans in the United States
The slave trade of Native Americans lasted only until around 1750. It gave rise to a series of devastating wars among the tribes, including the Yamasee War. The Indian Wars of the early 18th century, combined with the increasing importation of African slaves, effectively ended the Native American slave trade by 1750. Colonists found that Native American slaves could easily escape, as they knew the country. The wars cost the lives of numerous colonial slave traders and disrupted their early societies. The remaining Native American groups banded together to face the Europeans from a position of strength. Many surviving Native American peoples of the southeast strengthened their loose coalitions of language groups and joined confederacies such as the Choctaw, the Creek, and the Catawba for protection. Even after the Indian Slave Trade ended in 1750 the enslavement of Native Americans continued in the west, and also in the Southern states mostly through kidnappings.
