For more than 150 years, mounted Comanche warriors were “the Lords of the Southern Plains,” The Comanche lived in a large area known as Comancheria, and they raided over an area that stretched from southern Colorado and Kansas to northern Mexico.They shared Comancheria with the Wichita, Kiowa, and Kiowa Apache and, after 1840, the southern Cheyenne and Arapaho.Comanche power peaked in the 1840s when they conducted large scale raids hundreds of miles deep into Mexico while also warring against the Anglo-Americans and Hispanics in Texas.
