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.
History of conservatism in the United States
Except briefly in the 1860s-1870s, in the United States there has never been a national political party called the Conservative Party. All major American political parties support republicanism and the basic classical liberal ideals on which the country was founded in 1776, emphasizing liberty, the pursuit of happiness, the rule of law, the consent of the governed, opposition to aristocracy, and fear of corruption, coupled with equal rights. Political divisions inside the United States often seemed minor or trivial to Europeans, where the divide between the Left and the Right led to violent polarization, starting with the French Revolution.
