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.
1854 and 1855 United States Senate elections
In 1854, the Republican Party was founded as a national party, but in New York the Whigs and the Anti-Nebraska Party ran concurrently at the State election. The unification of these occurred in New York only during the nomination convention for the State election in November 1855. Also running in the 1854 election were the American Party and nominees of the Temperance movement. In a general way, party lines were blurred until the re-alignment during the late 1850s after the disbanding of the American Party.
