The Creek Confederacy was a confederation of nations with diverse customs and histories. Over several decades, they had ceded small portions of their vast territory to the United States in various treaties. They had been allies with the Great Britain in the War of 1812. The 1814 Treaty of Fort Jackson which ended the Creek War stipulated that the Creeks would cede 23 million acres (93,000 km²) of prime territory to the United States, leaving the Creeks a tract around the Chattahoochee River. The Creek Confederacy enacted a law that made further land cessions a capital offense. However, by mid-1820s, both political parties in Georgia favored the total removal of Native Americans west of the Mississippi River. Democratic Governor George Troup aggressively moved to resolve the situation.
