The Democratic Party is a liberal political party in the United States. Sitting on the center to center-left of the political spectrum, it is the world's oldest active political party, having been founded in 1828. Its main rival is the conservative Republican Party, and since the 1850s both have dominated American politics.
It initially supported Jacksonian democracy, agrarianism, and geographical expansionism, while opposing a national bank and high tariffs. Democrats won six of the eight presidential elections from 1828 to 1856, losing twice to the Whigs. In 1860, the party split into Northern and Southern factions over slavery. The party remained dominated by agrarian interests, contrasting with Republican support for the big business of the Gilded Age. Democratic candidates won the presidency only twice between 1860 and 1908 though they won the popular vote two more times in that period. During the Progressive Era, some factions of the party supported progressive reforms, with Woodrow Wilson being elected president in 1912 and 1916.
