Why Before and during Jackson's term as president Southern states argued that Native American land?

Before and during Jackson's presidency, Southern states argued that Native American land was necessary for their expansion and economic growth, particularly for agriculture and cotton cultivation. They viewed the removal of Native Americans as essential for accessing fertile land and ensuring their own prosperity. Additionally, there was a prevailing belief in the racial and cultural superiority of settlers, which justified their claims to Native lands. This mindset culminated in policies like the Indian Removal Act of 1830, which sought to relocate Native American tribes to areas west of the Mississippi River.
