Born in March 1768, Tecumseh was a Shawnee chief who had lost his father in Lord Dunmore’s War. He spent several years building a military alliance of over two dozen Indigenous Nations with the goal of ending the westward expansion of white settlers once and for all. Seven months before the U.S. Congress declared war on Great Britain, Tecumseh’s confederacy fought future president William Henry Harrison at the Battle of Tippecanoe in what’s now northern Indiana (though Tecumseh himself wasn’t there).
After the battle, Tecumseh’s confederacy forged on. In a politically expedient move, Tecumseh allied himself with the British once the War of 1812 broke out. Native American forces helped Great Britain take Detroit and repel American invaders from Queenston, Ontario. They also facilitated the capture of over 300 U.S. soldiers at the Battle of Beaver Dams. But after Tecumseh was mortally wounded at the Battle of Thames (1813), his confederacy unraveled.
