Tecumseh's war was a conflict between the United States and an American Indian confederation led by Shawnee leader Tecumseh in Indiana territory. Although the war is often considered to have culminated with William Henry Harrison's victory at the Battle of Tippecanoe in 1811, the Tecumseh War essentially continued in the war of 1812, and is often considered a part of that larger struggle. The war lasted for another two years, until the fall of 1813, when Tecumseh, as well as his second in command, Roundhead, died fighting the Northwest Harrison Army at the Thames Battle of Upper Canada, near present-day Chatham, Ontario, and his confederation disintegrated. Tecumseh's War is viewed by some academic historians as the final conflict of a long-term military struggle for control of the Great Lakes region of North America, spanning a series of wars over several generations, referred to as the War Years.
