Treaty of August 11, 1820
On August 11, 1820, Commissioners led by Benjamin Parke finalized a treaty with the Wea tribe, whereby the tribe ceded their lands from a previous treaty for compensation of $5,000 in money and goods. The Wea chiefs also agreed to relocate, with annuities promised to be paid in Illinois. The treaty required ratification by the U.S. President and Senate to take effect. Several Wea leaders marked the document alongside Parke, confirming the agreement’s legitimacy.
