Final answer:
Handsome Lake was a prophet who revitalized the Seneca Indians by promoting the return to traditional practices and resisting European influences.
Step-by-step explanation:
Handsome Lake was a prophet who revitalized the Seneca Indians by preaching a message of revival and reform similar to other Native American leaders of the time. Just as the Shawnee prophet Tenskwatawa called for a return to traditional native ways and rejection of European influences, Handsome Lake urged the Seneca Indians to renew their traditional practices, beliefs, and rituals. His influence was part of a wider Native American movement to resist cultural assimilation and preserve indigenous heritage in the face of American expansion and societal change.
