Answer:
The Battle of Tippecanoe contributed to the War of 1812 by providing the United States with a decisive victory over the Native American confederacy led by Tecumseh. This American victory showed the British that the United States was committed to defending its territories and would not be intimidated by threats from Native American tribes. This helped to strengthen the American resolve to fight against Britain in the War of 1812, which eventually resulted in the United States gaining their independence from Britain.
