After the disappearance of the Federalists after 1815 and the subsequent "Era of Good Feelings" (1816–1824), a group of weakly organized political factions dominated the American political landscape until about 1828–1832, when the modern Democratic Party emerged along with its rival, the Whigs. Democratic factions rallied behind charismatic President Jackson, whose conception of democracy guided the party's political agenda throughout the 1830s and through the antebellum period.
