Andrew Jackson (March 15, 1767 – June 8, 1845) was an American soldier and statesman who served as the seventh president of the United States from 1829 to 1837. Before being elected to the presidency, Jackson gained fame as a general in the United States Army and served in both houses of the U.S. Congress. As president, Jackson sought to advance the rights of the 'common man' against a 'corrupt aristocracy' and to preserve the Union. In his retirement, Jackson remained active in Democratic Party politics, supporting the presidencies of Martin Van Buren and James K. Polk. Many of his actions proved divisive, garnering both fervent support and strong opposition from many in the country.
