Why were Indian attacks on colonists considered revitalization movements?

White/Indian Relations and Slavery in the Colonies-Relations between colonists and Indians were occasionally cooperative, but generally distrustful and occasionally hostile. Indians often concluded that attempting to get along with the English was a failed strategy, and so determined to fight the colonists. In 1622, Indians living near Jamestown led by Opechancanough (Powhatan's brother and successor) fought to reclaim their land from the British invaders and to restore the Indians' original way of life. They nearly succeeded. Indian attacks killed more than 300 colonists and nearly wiped out the colony. These Indian rebellions were commonly called revitalization movements, because the Indians not only fought against the colonists, but also sought to return to their original way of life, before contact with Europeans. The colonists, in turn, became increasingly hostile toward the Indians. In 1644, Opechancanough led another revolt against the colonists, but was defeated. By 1645, the English had forced the Indians to surrender most of the lands along the Chesapeake Bay.
