Democratic-Republican Party

The Democratic-Republican Party, known at the time as the Republican Party (also referred to by historians as the Jeffersonian Republican Party), was an American political party founded by Thomas Jefferson and James Madison in the early 1790s. It championed liberalism, republicanism, individual liberty, equal rights (for White men, as common at the time), separation of church and state, freedom of religion, anti-clericalism, emancipation of religious minorities, decentralization, free markets, free trade, and agrarianism. In foreign policy, it was hostile to Great Britain and sympathetic to the French Revolution and Napoleonic Wars. The party became increasingly dominant after the 1800 elections as the opposing Federalist Party collapsed.

Increasing dominance over American politics also led to increasing factional splits within the party. Old Republicans, led by John Taylor of Caroline and John Randolph of Roanoke, believed that the administrations of Jefferson, Madison, and Monroe—and the Congresses led by Henry Clay—had in some ways betrayed the republican "Principles of '98" by expanding the size and scope of the national government. The Republicans splintered during the 1824 presidential election. Those calling for a return to the older founding principles of the party were often referred to as "Democratic Republicans" (later Democrats) while those embracing the newer nationalist principles of "The American System" were often referred to as National Republicans (later Whigs).

The Republican Party originated in Congress to oppose the nationalist and economically interventionist policies of Alexander Hamilton, who served as Secretary of the Treasury under President George Washington. The Republicans and the opposing Federalist Party each became more cohesive during Washington's second term, partly as a result of the debate over the Jay Treaty.
