History of Chicago

In 1795, following the Northwest Indian War, an area that was to be part of Chicago was turned over to the United States for a military post by native tribes in accordance with the Treaty of Greenville. In 1803, the United States Army built Fort Dearborn, which was destroyed in the War of 1812, Battle of Fort Dearborn and later rebuilt. The Ottawa, Ojibwe, and Potawatomi tribes had ceded additional land to the United States in the 1816 Treaty of St. Louis.
