The First Party System was the political party system in the United States between roughly 1792 and 1824. It featured two national parties competing for control of the presidency, Congress, and the states: the Federalist Party, created largely by Alexander Hamilton, and the rival Jeffersonian Democratic-Republican Party, formed by Thomas Jefferson and James Madison, usually called at the time the Republican Party.

Thomas Jefferson was an American statesman, diplomat, lawyer, architect, philosopher, and Founding Father who served as the third president of the United States from 1801 to 1809. He was the primary author of the Declaration of Independence. Following the American Revolutionary War and prior to becoming president in 1801, Jefferson was the nation's first U.S. secretary of state under George Washington and then the nation's second vice president under John Adams.
