Indian tribes kept their distance from the white Americans. They attempted to move Westwards but the Americans followed them for their goal of claiming more land. By the 1820s there were only 5 tribes trying to live alongside the Americans. Some converted to Christianity, wore white clothes, and created their own civilisations that somewhat resembled the white settlers. In the 1830s the "removal of Indians" act was passed, and any remaining tribes had to move to Oklahoma, where all the tribes could live together away from the Americans. The Indians did not like this and fought back, but were outmatched. They eventually moved, and by 1838 almost all land in the South was eventually open for white settlers.
