Indian resistance to American expansion came to a head, with the leadership of Shawnee brothers Tecumseh and Tenskwatawa ("The Prophet"), in a conflict that became known as Tecumseh's War.[55] Tenskwatawa convinced the tribes that they would be protected by the Great Spirit and no harm could befall them if they rose up against the settlers.
