Blue Jacket, or Weyapiersenwah, was a war chief of the Shawnee people, known for his militant defense of Shawnee lands in the Ohio Country. Blue Jacket participated in Lord Dunmore's War and the American Revolutionary War (allied with the British), always attempting to maintain Shawnee land rights. With the British defeat in the American Revolutionary War, the Shawnee lost valuable assistance in defending the Ohio Country. The struggle continued as white settlement in Ohio escalated, and Blue Jacket was a prominent leader of the resistance. He was present during the 1790 Harmar campaign and may have been one of the leaders who organized the defense. On November 3, 1791, the army of a confederation of Indian tribes, led by Blue Jacket and Miami Chief Little Turtle, defeated an American expedition led by Arthur St. Clair, governor of the Northwest Territory. In 1805, Blue Jacket also signed the Treaty of Fort Industry, relinquishing even more of Ohio. In Blue Jacket's final years, he saw the rise to prominence of Tecumseh, who would take up the banner and make the final attempts to reclaim Shawnee lands in the Ohio Country.
