What was the sgnificance of Tecumseh death who was the famous shawnee leader.
It was HUGE. Tecumseh was a dynamic individual capable of bringing separate tribes of native Americans together in a coalition that would have been a very real threat to white European supremacy in the area of America between the Appalachian mountains and the Mississippi river. While he was away securing alliances with tribes throughout what became the Southern states, his brother (the Prophet) undermined Tecumseh's efforts by urging an attack on William Henry Harrison's small U.S. territorial army at Tippecanoe creek in 1811. Tecumseh may have bounced back from this 1811 defeat, but his death in battle during 1813 left a vacancy in leadership that no one else could fill. No other leader from the Shawnee or any other tribe could get the various tribes anywhere close to fighting together.
I teach my college world history classes that the one truly significant event of the War of 1812 was the death of Tecumseh which essentially ended the Indian threat west of the Mississippi.
