Tecumseh - Wikipedia

On October 5, 1813, Tecumseh, Shawnee Chief (Battle of Thames), died in battle at 45. From the article:

"Tecumseh was among the most celebrated Indian leaders in history and was known as a strong and eloquent orator who promoted tribal unity. He was also ambitious, willing to take risks, and make significant sacrifices to repel the Americans from Indian lands in the Old Northwest Territory. In 1808, with his brother Tenskwatawa ("The Prophet"), Tecumseh founded the Indian village the Americans called Prophetstown, located north of present-day Lafayette, Indiana. Prophetstown grew into a large, multi-tribal community and a central point in Tecumseh's political and military alliance.

Tecumseh's confederation fought the United States during Tecumseh's War, but he was unsuccessful in getting the U.S. government to rescind the Treaty of Fort Wayne (1809) and other land-cession treaties. In 1811, as he traveled south to recruit more allies, his brother Tenskwatawa initiated the Battle of Tippecanoe against William Henry Harrison's army, but the Indians retreated from the field and the Americans burned Prophetstown. Although Tecumseh remained the military leader of the pan-Indian confederation, his plan to enlarge the Indian alliance was never fulfilled.

Tecumseh and his confederacy continued to fight the United States after forming an alliance with Great Britain in the War of 1812. During the war, Tecumseh's confederacy helped in the capture of Fort Detroit. However, after U.S. naval forces took control of Lake Erie in 1813, the British and their Indian allies retreated into Upper Canada, where the American forces engaged them at the Battle of the Thames on October 5, 1813, where Tecumseh was killed. His death and the end of the war caused the pan-Indian alliance to collapse. Within a few years, the remaining tribal lands in the Old Northwest were ceded to the U.S. government and subsequently opened for new settlement and most of the American Indians eventually moved west, across the Mississippi River. Since his death Tecumseh has become an iconic folk hero in American, Aboriginal, and Canadian history.[6]"
