Treaty of St. Louis (1804)

The Treaty of St. Louis of 1804 was a treaty concluded by William Henry Harrison on behalf of the United States of America and five Sauk and Meskwaki chiefs led by Quashquame.

The land ceded to the United States in the 1804 treaty is shown here in yellow.

The treaty transferred a huge area of land between the Mississippi and Illinois Rivers from the Sauk and Meskwaki to the United States. In return, the Sauk and Meskwaki received a lump-sum payment of $2234.50 and an annuity of $1000. This payment was far less than the value of the land. The signatory chiefs were not authorized to cede land by their tribes and probably did not understand the treaty. The Sauk and Meskwaki deeply resented the treaty and considered it invalid. It alienated them from the United States and encouraged them to ally with Britain, contributing to their support for the British during the later War of 1812.
