William H. Seward
The Republican Party had been founded in 1854, in reaction to the Kansas-Nebraska Act. Its anti-slavery stance was attractive to Seward, but he needed the Whig structure in New York to get re-elected. In September 1855, the New York Whig and Republican parties held simultaneous conventions that quickly merged into one. Seward was the most prominent figure to join the new party, and was spoken of as a possible presidential candidate in 1856. Weed, however, did not feel that the new party was strong enough on a national level to secure the presidency, and advised Seward to wait until 1860. When Seward's name was mentioned at the 1856 Republican National Convention, a huge ovation broke out. In the 1856 presidential election, the Democratic candidate, former Pennsylvania senator James Buchanan, defeated the Republican, former California senator John C. Frémont, and the Know Nothing candidate, former president Fillmore.
History of the United States Republican Party
The Republican Party, also referred to as the GOP (abbreviation for Grand Old Party), is one of the world's oldest extant political parties. The party values reflect economic conservatism, classical conservatism (modern day American conservatism) and corporate liberty rights. It is the second oldest existing political party in the United States after its primary rival, the Democratic Party. The party emerged in 1854 to combat the Kansas–Nebraska Act, an act that dissolved the terms of the Missouri Compromise and allowed slave or free status to be decided in the territories by popular sovereignty. The early Republican Party had almost no presence in the Southern United States, but by 1858 it had enlisted former Whigs and former Free Soil Democrats to form majorities in nearly every Northern state.
