Political Parties
From Federalists and Republicans to the modern two-party system
c. 1790s–present

Political parties are not mentioned in the Constitution, and many founders hoped to avoid them. But parties formed almost immediately and have organized American politics ever since. The Federalists and Jefferson’s Democratic-Republicans gave way to Jacksonian Democrats and Whigs, and in the 1850s the antislavery Republican Party was born. Since then Democrats and Republicans have dominated a two-party system, even as their coalitions and ideas have shifted dramatically.

Why it matters
Parties are the machinery of American democracy: they turn public opinion into governing coalitions, and their realignments mark the great turning points in American political history.
Origins
The founding generation tried to create a national government free of parties, but the effort proved unworkable. By the mid-1790s, Federalists led by Alexander Hamilton and Democratic-Republicans led by Jefferson and James Madison divided over the power of the national government, the economy, and foreign policy. Within a decade, the House’s historians note, parties absorbed the various state and local factions. Jefferson’s victory in the election of 1800 brought the first peaceful transfer of power between parties.
Powers and limits
Parties nominate candidates and organize voters. According to the House’s historians, parties quickly proved their worth in organizing the work of the House and in bridging the separation of powers between Congress and the president.
How it changed over time
Under Martin Van Buren, Jackson’s supporters built the Democratic Party, the first modern party, with a centralized structure and a consistent program. Jackson’s opponents organized as the Whigs in 1834. In 1854, after the Kansas-Nebraska Act, antislavery forces formed the Republican Party, which elected Abraham Lincoln in 1860. Franklin D. Roosevelt’s New Deal built a Democratic coalition of liberals, urban workers, farmers, and white Southerners that dominated politics into the 1960s. Conservative reaction against the Great Society helped Republicans rise in the South and West, and the rise of the religious right and Ronald Reagan’s victory in 1980 marked a conservative realignment.
