Answer:
As a result of the Creek War, most Creeks relocated to Indian Territory.
Step-by-step explanation:
The Creek War of 1813-1814 began as a civil war among the Creek Indians, but was expanded to become part of the 1812 War. The war ended with peace in Fort Jackson in 1814, when the creeks were forced to withdraw most of Alabama and the southern part of Georgia to the United States. The civil war was fought between the Red Sticks, a traditionalist faction, who aggressively fought for a return to the traditional social life of the people based on hunting and collective land property, and White Sticks, the Creeks who had become acculturated and had taken over a Euro-American way of life with private land ownership, large plantations and African slaves. The war began in 1813, when a small group of Red Sticks murdered two white settler families on the Ohio River. The Creek Indians' agent demanded that the killers be extradited to the US judiciary. Instead, the creeks executed the perpetrators themselves. This was the spark that triggered the civil war.
In mid-March 1814, Andrew Jackson advanced with forces from the Tennessee National Guard and a US Army regiment as well as Native American allies against the Red Sticks who had gathered along Tallapoosa. In the Battle of Horseshoe Bend, Jackson's forces defeated the Red Sticks and the war was over. As a result, the Creeks were forced to forgo 93,000 km² of Creek land and relocate to the reservations.
