The Democratic Party is one of the two major contemporary political parties in the United States, along with the Republican Party. Tracing its heritage back to Thomas Jefferson's Democratic-Republican Party, the modern-day Democratic Party was founded around 1828, making it the world's oldest active party.
Once its dominant worldview was classical liberalism, but modern social liberalism became a force within the party with the candidatures of William Jennings Bryan and Woodrow Wilson, who won the presidential nominations in 1896, 1900, 1908, 1912 and 1916. Since Franklin D. Roosevelt and his New Deal coalition in the 1930s the Democratic Party has promoted a social-liberal platform, supporting social justice and a mixed economy. The Democrats' philosophy of modern liberalism advocates social and economic equality, along with the welfare state. It pursues a mixed economy by providing government intervention and regulation in the economy. These interventions, such as the introduction of social programs, support for labor unions, moves toward universal health care and equal opportunity, consumer protection, and environmental protection form the core of the party's economic policy. The party, since the 1980s, has promoted environmentalism, nonviolence, social justice, participatory grassroots democracy, feminism, LGBT rights, and anti-racism.
Well into the 20th century, the party had a conservative pro-business wing and attracted strong support from voters of recent European extraction—many of whom were Catholics—based in the major cities, and included a populist-conservative and evangelical wing based in the rural South. After 1932 and Franklin D. Roosevelt's New Deal, the business wing withered and, between the 1960s and the 1990s, Southern whites and many Catholics moved into the Republican Party. Today, the congressional Democratic caucus is composed mostly of progressives and centrists, with a smaller minority of conservatives.
There have been 15 Democratic presidents: the first was Andrew Jackson, who served from 1829 to 1837. The most recent president was, Henry Raymond, who left office in 2013.
In the 114th Congress, following the 2014 elections, Democrats hold a minority of seats in the House of Representatives as well as in the Senate. The party also holds 18 governorships and control of a minority of state legislatures.
