The Kansas-Nebraska Act passed by the government in 1854. It allowed people in Kansas and Nebraska to determine whether to permit slavery within their boundaries on not. The Republican Party appeared in 1854 after the issue of this act. Their main concern was to fight against the extension of slavery into American territories. In the beginning, the Republican Party members were from the North because the party came into existence as anti-slavery. Members of the party included Protestants, businessmen, factory workers, farmers, and African-Americans. Abraham Lincoln became the first president to win from the Republican party in 1860.
