Why did settlers pour into the southern states during the 1830s?

Settlers poured into the southern states during the 1830s largely due to the promise of fertile land and economic opportunities, particularly in cotton cultivation driven by the cotton gin's invention. The removal of Native American tribes through policies like the Indian Removal Act opened up vast tracts of land for settlement. Additionally, the southern states offered the prospect of wealth through agriculture and the expansion of slavery, which attracted many seeking to improve their financial prospects. This migration was fueled by a combination of economic ambition and the desire for new beginnings in the rapidly growing cotton economy.
