The Democratic Party is one of two major political parties in the United States, the other being the Republican Party. The party under its present name was established by Andrew Jackson during the 1820s, but it traces its origins to Thomas Jefferson and the Democratic-Republican Party in 1792. It is the oldest political party in the world.

Currently, the Democratic Party is the minority party in the United States Senate and the House of Representatives. Democrats control 19 state legislatures and 22 governorships.
Since 1896, the Democrats have been the more liberal major party (in the modern American sense of the word, i.e. center-left). The pro-working class, activist philosophy of Franklin D. Roosevelt has shaped much of the party's agenda since 1933; his New Deal coalition controlled the national government into the 1960s. The Civil Rights Movement of the 1960s, championed by the party despite opposition at the time from its conservative Southern wing, has continued to inspire the party's ideas and principles.
