The Indian Removal Act of 1830 was signed into law on May 28, 1830, by United States president Andrew Jackson. The law, as described by Congress, provided "for an exchange of lands with the Indians residing in any of the states or territories, and for their removal west of the river Mississippi". During the presidency of Jackson (1829‍–‍1837) and his successor Martin Van Buren (1837‍–‍1841), more than 60,000 American Indians from at least 18 tribes were forced to move west of the Mississippi River where they were allocated new lands. The southern Indian tribes were resettled mostly into what became the Indian Territory (Oklahoma). The northern Indian tribes were resettled initially in Kansas. With a few exceptions, the United States east of the Mississippi and south of the Great Lakes was emptied of its American Indian population. The movement westward of Indian tribes was characterized by a large number of deaths due to the hardships of the journey.
