Explanation:
The Indian Removal Act of 1830 was signed into effect by President Jackson, which allowed Native Americans to settle in land within state borders in exchange for unsettled land.

Due to this, some tribes were unwilling to move. One significant example is the Cherokee tribe, who was forcibly led to move from their homelands by US soldiers. Over 4000 Cherokee Native Americans died on this trail, which is now known as the "Trail of Tears."
