Andrew Jackson (March 15, 1767 – June 8, 1845) was the seventh president of the United States, serving from 1829 to 1837. Before his presidency, he gained fame as a general in the U.S. Army and served in both houses of the U.S. Congress. Often praised as an advocate for ordinary Americans and for his work in preserving the union of states, Jackson has also been criticized for his racial policies, particularly his treatment of Native Americans.
