Answer:Early in the 19th century, while the rapidly-growing United States expanded into the lower South, white settlers faced what they considered an obstacle. This area was home to the Cherokee, Creek, Choctaw, Chicasaw and Seminole nations. These Indian nations, in the view of the settlers and many other white Americans, were standing in the way of progress. Eager for land to raise cotton, the settlers pressured the federal government to acquire Indian territory.
Andrew Jackson, from Tennessee, was a forceful proponent of Indian removal. In 1814 he commanded the U.S. military forces that defeated a faction of the Creek nation. In their defeat, the Creeks lost 22 million acres of land in southern Georgia and central Alabama. The U.S. acquired more land in 1818 when, spurred in part by the motivation to punish the Seminoles for their practice of harboring fugitive slaves, Jackson's troops invaded Spanish Florida.
From 1814 to 1824, Jackson was instrumental in negotiating nine out of eleven treaties which divested the southern tribes of their eastern lands in exchange for lands in the west. The tribes agreed to the treaties for strategic reasons. They wanted to appease the government in the hopes of retaining some of their land, and they wanted to protect themselves from white harassment. As a result of the treaties, the United States gained control over three-quarters of Alabama and Florida, as well as parts of Georgia, Tennessee, Mississippi, Kentucky and North Carolina. This was a period of voluntary Indian migration, however, and only a small number of Creeks, Cherokee and Choctaws actually moved to the new lands.
