The Indian Removal Act
Explanation:
The Indian Removal Act was promoted, and signed into law by president Andrew Jackson ini 1930. The Act allowed the president to negotiate with several native american nations (the Cherokee, the Choctaw, the Chicasaw, etc) who lived in the southeastern United States for their removal from those areas, and their relocation to a new designated Indian Territory west of the Mississippi river (mostly in Oklahoma).
