Andrew Jackson, known as "Old Hickory," as an officer in the war of 1812 defeated the British at New Orleans in 1815 and as the seventh president of the United States from 1829 to 1837 opposed the bank, strengthened Federal powers, and pursued policies that forced thousands of Native Americans to relocate to the west.
He commanded at the battle in 1815 and served as military governor of Florida in 1821. This polarizing figure, the eponym of the era of democracy, dominated politics in the 1820s and 1830s. His political ambition, combined with the masses of persons, shaped the modern Democratic Party. People nicknamed him for his renowned toughness. Jackson, first and primarily associated with the frontier, based his career in Tennessee.
