Tecumseh's War: American forces led by William Henry Harrison defeated the forces of Shawnee leader Tecumseh's growing confederation at the Battle of Tippecanoe near present-day Battle Ground, Indiana.

Tecumseh's War was a conflict between the United States and Tecumseh's confederacy, led by the Shawnee leader Tecumseh in the Indiana Territory. Although the war is often considered to have climaxed with William Henry Harrison's victory at the Battle of Tippecanoe in 1811, Tecumseh's War essentially continued into the War of 1812 and is frequently considered a part of that larger struggle. The war lasted for two more years, until 1813, when Tecumseh died fighting Harrison's Army of the Northwest at the Battle of Moraviantown in Upper Canada, near present-day Chatham, Ontario, and his confederacy disintegrated. Tecumseh's War is viewed by some academic historians as the final conflict of a longer-term military struggle for control of the Great Lakes region of North America, encompassing a number of wars over several generations, referred to as the Sixty Years' War.
