Born in poverty, Andrew Jackson (1767-1845) had become a wealthy Tennessee lawyer and rising young politician by 1812, when war broke out between the United States and Britain. His leadership in that conflict earned Jackson national fame as a military hero, and he would become America’s most influential–and polarizing–political figure during the 1820s and 1830s. After narrowly losing to John Quincy Adams in the contentious 1824 presidential election, Jackson returned four years later to win redemption, soundly defeating Adams and becoming the nation’s seventh president (1829-1837). As America’s political party system developed, Jackson became the leader of the new Democratic Party. A supporter of states’ rights and slavery’s extension into the new western territories, he opposed the Whig Party and Congress on polarizing issues such as the Bank of the United States. For some, his legacy is tarnished by his role in the forced relocation of Native American tribes living east of the Mississippi.
