About this source

What it is

This is the 1809 Treaty of Fort Wayne, negotiated by Territorial Governor William Henry Harrison with several Native American peoples, mainly the Lenape (Delaware) and other tribes along the Wabash River. A related document, a War Department letter instructing Harrison on negotiations, is also shown here.

Why it matters

The treaty obtained a vast cession of land for American settlers in Illinois and Indiana. It excluded the Shawnee, and its legitimacy was fiercely disputed by Shawnee leader Tecumseh, who argued that no single group of leaders had the right to sell land held in common. The dispute helped lead to Tecumseh's War and the Battle of Tippecanoe.

Why it matters

The treaty shows how Harrison used subsidies, payments, and even distributed alcohol during negotiations to secure tribal agreement, despite his public opposition to supplying alcohol to Native Americans.

Look closer

  • Why did Harrison negotiate with some tribes first before approaching others?
  • What does Tecumseh's objection reveal about different ideas of land ownership?
  • Why might the treaty exclude a group like the Shawnee who lived in the area?
