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.
Yaqui Wars
The Yaqui Wars, were a series of armed conflicts between New Spain, and the later Mexican Republic, against the Yaqui Indians. The period began in 1533 and lasted until 1929. The Yaqui Wars, along with the Caste War against the Maya, were the last conflicts of the centuries long Mexican Indian Wars. Over the course of nearly 400 years, the Spanish and the Mexicans repeatedly launched military campaigns into Yaqui territory which resulted in several serious battles and some infamous massacres.
