Excerpts from Books and Wikipedia
"It is usually considered part of the War of 1812 . . . and the Red Sticks [Creeks with war clubs] had sought British support and aided Admiral Cochrane's advance towards New Orleans. The Creek War began as a conflict within the Creek Confederation, but local white militia units quickly became involved. British traders in Florida as well as the Spanish government provided the Red Sticks with arms and supplies because of their shared interest in preventing the expansion of the United States into their areas. The United States government formed an alliance with the Choctaw Nation and Cherokee Nation . . . to put down the rebellion. The war effectively ended with the Treaty of Fort Jackson (August 1814), when General Andrew Jackson forced the Creek confederacy to surrender more than 21 million acres in what is now southern Georgia and central Alabama." [Wikipedia] "[Jackson] believed citizenship inevitable for the more civilized Indians, and he argued that Indian life and heritage might be preserved (and should be preserved) through removal." [Andrew Jackson 1, p. 336-7]
