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.
Political parties in the United States
The Fifth Party System emerged with the New Deal Coalition beginning in 1933. The Republicans began losing support after the Great Depression, giving rise to Democratic President Franklin D. Roosevelt and the activist New Deal. They promoted American liberalism, anchored in a coalition of specific liberal groups, especially ethno-religious constituencies (Catholics, Jews, African Americans), white Southerners, well-organized labor unions, urban machines, progressive intellectuals, and populist farm groups.
