The Jeffersonian Party was founded by Thomas Jefferson in 1792 as a congressional caucus in support of the Bill of Rights. In 1800, Thomas Jefferson was elected President of the United States, becoming the first of three Jeffersonian Presidents (John Madison and James Monroe being the other two), who held the presidency for 24 consecutive years. The election of John Quincy Adams in 1824 led to a temporary dissolution of the party.

In the year 2000, nearly 175 years after it’s dissolution, the Jeffersonian Party reemerged as a voice for states rights and constitutional adherence. It's mission was simple: assist the reelection efforts of U.S. House and Senate members who support and adhere to the founding principles of Thomas Jefferson.

These principles have been extracted from the vast writings and speeches of Thomas Jefferson to formulate a complete contemporary Jeffersonian philosophy, which is clearly outlined in the party platform.
