In 1805, plains Indians in the Midwest were feeling the threat of westward expansion by white pioneers. Tecumseh, a member of the Shawnee tribe, used the growing worry of disparate tribes to bring them together into a confederacy with the common goal of saving their ancestral land. The dream of a separate Indian nation state would die along with Tecumseh when he was killed in battle in 1813.
Tecumseh "Shooting Star" or "Panther Across The Sky", (March 1768 -- October 5, 1813) was a Native American leader of the Shawnee and a large tribal confederacy (known as Tecumseh's Confederacy) which opposed the United States during Tecumseh's War and the War of 1812. Tecumseh has become an icon and heroic figure in American Indian and Canadian history.
Tecumseh grew up in the Ohio Country during the American Revolutionary War and the Northwest Indian War, where he was constantly exposed to warfare. With Americans continuing to encroach on Indian territory after the British ceded the Ohio Valley to the new United States in 1783, the Shawnee moved further northwest. In 1808, they settled Prophetstown in present-day Indiana. With a vision of establishing an independent American Indian nation east of the Mississippi, Tecumseh worked to recruit additional tribes to the confederacy from the southern United States.
