The Creek tribe fell to civil war (1813–1814). Violence between Creeks and Americans escalated, culminating in the Fort Mims massacre. Full-scale war between the United States and the "Red Stick" Creeks began; they were the more traditional members of their society who resisted US encroachment. The Chickasaw, Choctaw, Cherokee Nation and other Creek factions remained neutral to or allied with the United States during the war; they were highly decentralized in bands' alliances. Some warriors from among the bands served with American troops. Volunteer militias from Georgia, South Carolina and Tennessee marched into Alabama, fighting the Red Sticks.
