The Democratic Party is one of two major political parties in the United States, alongside the Republican Party. The party was founded in 1828 by Andrew Jackson after the dissolution of the Democratic-Republican Party, and it originally supported social conservatism, states' rights, and economic liberalism, while its Southern wing, the Southern Democrats, supported populism. The Democrats would remain a conservative political party until 1912, when the liberal, pro-Theodore Roosevelt faction of the Republican Party formed the Bull Moose Party ahead of the 1912 presidential election; the Democratic nominee Woodrow Wilson was elected as the first fiscally progressive Democrat. Since the New Deal of the 1930s, the Democrats also supported social liberalism and social justice. The largely conservative Southern Democrats were convinced to defect to the Republicans from the 1960s to the 1990s as a result of the Civil Rights movement and the collapse of the "Solid South".
By the 21st century, the Democratic Party was dominated by centrists and progressives, with a smaller minority of Conservative Democrats. The party advocated social and economic equality under the welfare state, and it sought to provide government intervention and regulation in the economy. The party's pro-business wing withered outside of the South as a result of the New Deal in the 1930s, and the racial turmoil of the 1960s led to most southern whites and many northern Catholics joining the Republicans. During the 1990s, white evangelicals and southerners gravitated towards the Republicans, and the Democrats found widespread support among racial and ethnic minorities (such as Jews, Hispanics, Arabs, and African-Americans).
