Andrew Jackson was an American soldier and statesman who served as the seventh President of the United States from 1829 to 1837 and is considered the founder of the Democratic Party. He was born near the end of the colonial era, somewhere near the then-unmarked border between North and South Carolina, into a recently immigrated Scots-Irish farming family of relatively modest means. During the American Revolutionary War, Jackson, whose family supported the revolutionary cause, acted as a courier. At age 13, he was captured and mistreated by the British army. He later became a lawyer. He was also elected to Congressional office, first to the U.S. House of Representatives and twice to the U.S. Senate. In 1801, Jackson was appointed colonel in the Tennessee militia, which became his political as well as military base. He owned hundreds of slaves who worked on the Hermitage plantation. In 1806, he killed a man in a duel over a matter of honor regarding his wife Rachel. He gained national fame through his role in the War of 1812, most famously where he won a decisive victory over the main British invasion army at the Battle of New Orleans. In response to conflict with the Seminole in Spanish Florida, he invaded the territory in 1818. This led directly to the First Seminole War and the Adams–Onís Treaty of 1819, which formally transferred Florida from Spain to the United States. After winning election to the Senate, Jackson ran for president in 1824. Although he got a plurality in both electoral and popular vote against three major candidates, Jackson failed to get a majority and lost in the House of Representatives to John Quincy Adams. Jackson claimed that he lost by a "corrupt bargain" between Adams and Speaker of the House Henry Clay, who was also a candidate, to give Clay the office of Secretary of State in exchange for Adams winning the presidency. Jackson's supporters then founded what became the Democratic Party. He ran again for president in 1828 against Adams. Building on his base in the West and with new support from Virginia and New York, he won by a landslide. He blamed the death of his wife, Rachel, which occurred just after the election, on the Adams campaigners, who called her a "bigamist". As president, Jackson faced a threat of secession by South Carolina over the "Tariff of Abominations", which Congress had enacted under Adams. In contrast to several of his immediate successors, he denied the right of a state to secede from the union or to nullify federal law. The Nullification Crisis was defused when the tariff was amended and Jackson threatened the use of military force if South Carolina attempted to secede. In anticipation of the 1832 election, Congress, led by Clay, attempted to reauthorize the Second Bank of the United States four years before the expiration of its charter. In keeping with his platform of economic decentralization, Jackson vetoed the renewal of its charter, thereby seemingly putting his chances for reelection in jeopardy. However, by portraying himself as the defender of the common person against wealthy bankers, he was able to defeat Clay in the election that year. He thoroughly dismantled the bank by the time its charter expired in 1836. His struggles with Congress were personified in his personal rivalry with Clay, whom Jackson deeply disliked and who led the opposition of the emerging Whig Party. Jackson's presidency marked the beginning of the ascendancy of the "spoils system" in American politics. He is also known for having signed the Indian Removal Act in 1830, which forcibly relocated a number of native tribes in the South to Indian Territory. Jackson supported his vice president Martin Van Buren's successful presidential campaign in 1836. He worked to bolster the Democratic Party and helped his friend James K. Polk win the 1844 presidential election.
