Question

What political, economics, and cultural forces contributed to the forced migration of Indians in the 1830's?

Answer 1

President Jackson and his supporters thought that White Americans and the Indians can't live in the same land as it will bring more conflict between the two. So, they introduced Indian Removal Act in 1830 which enabled the forced removal of the Indians from their lands to farthest lands.
Another reason was that the white Americans needed more fertile lands for farming and they found the east of the Mississippi River the opt place for farming. So, they drove the Indians who were living in the east to the west thus making room for more farming lands which in today's standard is illegal.

Seminole leaders wanted to fight the White rather than giving in to the forced removal and this became the reason for the 2nd Seminole War. Eventually, the Seminole leader was caught and he died in the prison. While so many Seminole people were killed, nearly 4000 were removed by force.
The Cherokee people believed that they could avoid conflict by learning the American way. So missionaries were sent to setup schools and educate the Cherokee during the early 1800 but they were also moved by force.
Although President Jackson was fondly called the people's president by the whites, he will remain a terrorist leader in the eyes of the Indians of his time.
