In 1805, Tecumseh's younger brother Tenskwatawa, who came to be known as the Shawnee Prophet, founded a religious movement, calling upon Native Americans to reject European influences and return to a more traditional lifestyle. In 1808, Tecumseh and Tenskwatawa established Prophetstown, a village in present-day Indiana, that grew into a large, multi-tribal community. Tecumseh traveled constantly, spreading the Prophet's message and eclipsing his brother in prominence. He proclaimed that Native Americans owned their lands in common, and urged tribes not cede more territory unless all agreed. His message alarmed American leaders as well as Native leaders who sought accommodation with the United States. In 1811, when Tecumseh was in the south recruiting allies, Americans under William Henry Harrison defeated Tenskwatawa at the Battle of Tippecanoe and destroyed Prophetstown.
