Answer:

The Republican Party emerged in 1854 to combat the Kansas–Nebraska Act and the expansion of slavery into American territories.

One may also ask, when did the Republicans and Democrats switch? After being the dominant party in U.S. politics from 1800 to 1829, the Democratic-Republicans split into two factions by 1828: the federalist National Republicans, and the Democrats. The Democrats and Whigs were evenly balanced in the 1830s and 1840s.
