Origins of the American Civil War
In almost every northern state, organizers attempted to have a Republican Party or an anti-Nebraska fusion movement on ballots in 1854. In areas where the radical Republicans controlled the new organization, the comprehensive radical program became the party policy. Just as they helped organize the Republican Party in the summer of 1854, the radicals played an important role in the national organization of the party in 1856. Republican conventions in New York, Massachusetts, and Illinois adopted radical platforms. These radical platforms in such states as Wisconsin, Michigan, Maine, and Vermont usually called for the divorce of the government from slavery, the repeal of the Fugitive Slave Laws, and no more slave states, as did platforms in Pennsylvania, Minnesota, and Massachusetts when radical influence was high.
Fifth Party System
The Fifth Party System is the era of American national politics that began with the New Deal in 1932 under President Franklin D. Roosevelt. This era emerged from the realignment of the voting blocs and interest groups supporting the Democratic Party into the New Deal coalition following the Great Depression. For this reason it is often called the "New Deal Party System". It followed the Fourth Party System, usually called the Progressive Era. Experts debate whether the Fifth Party System ended (and thus a Sixth Party System emerged) in the mid-1960s, the early 1980s (when the Moral Majority took off), the mid-1990s, or possibly continues to the present.
