Indian Removal

Andrew Jackson had long been an advocate of what he called “Indian removal.” As an Army general, he had spent years leading brutal campaigns against the Creeks in Georgia and Alabama and the Seminoles in Florida–campaigns that resulted in the transfer of hundreds of thousands of acres of land from Indian nations to white farmers. As president, he continued this crusade. In 1830, he signed the Indian Removal Act, which gave the federal government the power to exchange Native-held land in the cotton kingdom east of the Mississippi for land to the west, in the “Indian colonization zone” that the United States had acquired as part of the Louisiana Purchase. (This “Indian territory” was located in present-day Oklahoma.)
