Andrew Jackson (March 15, 1767 – June 8, 1845) was the seventh President of the United States (1829–1837). He was military governor of Florida (1821), commander of the American forces at the Battle of New Orleans (1815), and eponym of the era of Jacksonian democracy. A polarizing figure who dominated American politics in the 1820s and 1830s, his political ambition combined with widening political participation, shaping the modern Democratic Party. His legacy is now seen as mixed, as a protector of popular democracy and individual liberty, checkered by his support for Indian removal and slavery. Renowned for his toughness, he was nicknamed “Old Hickory”. As he based his career in developing Tennessee, Jackson was the first president primarily associated with the American frontier. His portrait appears on the U.S. twenty-dollar bill.

Andrew Jackson was born to Presbyterian Scots-Irish immigrants Andrew and Elizabeth Hutchinson Jackson, on March 15, 1767, approximately two years after they had emigrated from Carrickfergus, in Northern Ireland. Three weeks after his father's death, Andrew was born in the Waxhaws area near the border between North and South Carolina. He was the youngest of the Jacksons' three sons. His exact birth site was the subject of conflicting lore in the area. Jackson claimed to have been born in a cabin just inside South Carolina.

Jackson received a sporadic education in the local "old-field" school. During the American Revolutionary War, Jackson, at age thirteen, joined a local regiment as a courier. Andrew and his brother Robert Jackson were captured by the British and held as prisoners of war; they nearly starved to death in captivity. When Andrew refused to clean the boots of a British officer, the irate redcoat slashed at him with a sword, giving him scars on his left hand and head, as well as an intense hatred for the British. While imprisoned, the brothers contracted smallpox. Robert died a few days after their mother secured their release. Jackson's entire immediate family died from war-related hardships which Jackson blamed on the British, and he was orphaned by age 14.
