The 1803 Louisiana Purchase acquired 828,000 square miles for the U.S., doubling its size, and the Federal Road was built to provide a shorter route from Washington to New Orleans and the new territory. A treaty with the Creeks in 1805 authorized travel across their lands, and the road entered Alabama at Fort Mitchell near Columbus, Georgia, then passed through Mount Meigs, Pintlala, Fort Deposit, Burnt Corn, Fort Stoddert, and Mobile. The 1814 Treaty of Fort Jackson opened much fertile Creek land to cotton cultivation, and this lure, called Alabama Fever, drew many thousands of settlers to central Alabama; by 1860, spans were still in use, but the road was gone. Near here and near Pinchona Creek stood Manac's Tavern, the oldest stand on the Federal Road. Its proprietor, Samuel Manac, in 1701 went with Alexander McGillivray to the U.S. capitol in New York City and met George Washington to conclude a peace treaty for the Creek Nation, the U.S.'s first treaty with a foreign power. He married Elizabeth, the sister of Red Eagle. Aaron Burr stayed here in 1807. In 1822 Samuel's son David Moniac became the first Indian and first Alabamian to graduate from West Point. In 1836, during the Second Seminole War, Major Moniac was killed at Wahoo Swamp while leading a unit of Creek militia against the braves of Osceola, his wife's cousin.
