Born in the colonial Carolinas to a Scotch-Irish family in the decade before the American Revolutionary War, Jackson became a frontier lawyer and married Rachel Donelson Robards. He served briefly in the United States House of Representatives and the United States Senate, representing Tennessee. After resigning, he served as a justice on the Tennessee Supreme Court from 1798 until 1804. Jackson purchased a property later known as The Hermitage, and became a wealthy, slaveowning planter. In 1801, he was appointed colonel of the Tennessee militia and was elected its commander the following year. He led troops during the Creek War of 1813–1814, winning the Battle of Horseshoe Bend. The subsequent Treaty of Fort Jackson required the Creek surrender of vast lands in present-day Alabama and Georgia. In the concurrent war against the British, Jackson’s victory in 1815 at the Battle of New Orleans made him a national hero. Jackson then led U. S. forces in the First Seminole War, which led to the annexation of Florida from Spain. Jackson briefly served as Florida’s first territorial governor before returning to the Senate. He ran for president in 1824, winning a plurality of the popular and electoral vote. As no candidate won an electoral majority, the House of Representatives elected John Quincy Adams in a contingent election. In reaction to the alleged “corrupt bargain” between Adams and Henry Clay and the ambitious agenda of President Adams, Jackson’s supporters founded the Democratic Party.
