The Indian Removal Act of 1830 was a law passed by the United States Congress and signed by President Andrew Jackson to force the removal of Native American tribes in the United States living east of the Mississippi River to lands farther west. The law was enacted on May 26, 1830. The Cherokee tribe walked to what is now Oklahoma along the so-called Trail of Tears. Many of them died along the way.
