*Democratic-Republican Party--Definition: One of the first two American political parties, together with the Federalist Party. Founded by Thomas Jefferson and James Madison. Those two and James Monroe were the only Democratic-Republican presidents. Party disbanded in the 1820s, splintering into two factions, the Democratic Party and the Whig Party. Members of the Democratic-Republican Party believed that a strong federal government would weaken and not respect the rights of the states and the people.--Source: http://www.socialstudiesforkids.com/wwww/us/demorepubpartydef.htm
