REPUBLICAN PARTY FOUNDED IN WISCONSIN
Ripon, Wisconsin (JFK+50) On March 20, 1854, the Republican Party was founded here in Ripon. The party was organized by former Whigs and Free Soilers who aimed to establish a party in opposition to the spread of slavery into the western territories.
The leaders of the movement included Horace Greeley, Salmon Chase and Charles Sumner. In recommending the name 'Republican,' Mr. Greeley wrote...
"We think some simple name like Republican (will) more fitly designate those...united to restore the Union to its true mission of champion and promulgator of Liberty."
