The Comanche are a Native American group whose historical range (the Comancheria) consisted of present-day Eastern New Mexico, Southern Colorado, Southern Kansas, all of Oklahoma, and most of Northern and Southern Texas. There might once have been as many as 20,000 Comanches. Today, the Comanche Nation consists of approximately 10,000 members, about half of whom live in Oklahoma (centered at Lawton), with the remainder concentrated in Texas, California, and New Mexico.
