When swarms of immigrants to California crossed the Plains invast covered-wagon caravans, this intrusion on Indian domains brought many clashes between the two races. From 1843 to 1857 some 350,000 pioneers made thelong trek. Nearly everyone in the East had a relative on his way to the Pacific Coast. Thousands of tales about the hostile western tribes filtered back home. That ishow the Plains Indians became "The Indians" of North America in the minds of most people, and still remain so.
