Why did Americans want the remaining Indian lands in the South?

Americans sought the remaining Indian lands in the South primarily for economic expansion and agricultural development. The increasing demand for land to cultivate cash crops, such as cotton, fueled westward migration and settlement. Additionally, the ideology of manifest destiny convinced many that it was their right to expand across the continent, often at the expense of Native American populations. This desire for land led to policies and actions that forcibly removed Native Americans from their ancestral territories.
