The Comanche Wars were a series of armed conflicts fought between Comanche peoples and Spanish, Mexican, and American militaries and civilians in the United States and Mexico from as early as 1706 until at least the mid-1870s. The Comanche were the Native American inhabitants of a large area known as Comancheria, which stretched across much of the southern Great Plains from Colorado and Kansas in the north through Oklahoma, Texas, and eastern New Mexico and into the Mexican state of Chihuahua in the south. For more than 150 years, the Comanche were the dominant native tribe in the region, known as “the Lords of the Southern Plains”, though they also shared parts of Comancheria with the Wichita, Kiowa, and Kiowa Apache and, after 1840, the southern Cheyenne and Arapaho.
