The Treaty of Fort Jackson (also known as the Treaty with the Creeks) was signed on this day in 1814 at Fort Jackson in Alabama. The treaty was agreed upon in the aftermath of the defeat of Red Stick (Upper Creek) resistance by U.S. forces at the Battle of Horseshoe Bend.

The treaty was the "largest single Indian cession of southern American land", according to historian Michael Rogin - around 23 million acres in Alabama and Georgia. The U.S. forces won with the battle with the help of allied Cherokee and Lower Creek forces friendly to the American side.

The terms of various treaties with the Creek nation would go on to be consistently violated by Americans colonizing the south.
