Final answer:
The Republican Party was created during the OSecond Party System, following the split within the Democratic-Republican Party and evolving from factions including the Whig Party.
Step-by-step explanation:
The creation of the Republican Party occurred during the period known as the Second Party System. This era followed the First Party System, which consisted of the Federalists and the Jeffersonian Republicans. The Second Party System began with a split within the Democratic-Republican Party, leading to the formation of two new political parties. The first party, aligning with Andrew Jackson, continued under the name of the Democratic Party, whereas the faction supporting economic industrial development became known as the National Republicans and later evolved into the Whig Party. Eventually, from the Whig Party and others who opposed the Kansas-Nebraska Act, the modern Republican Party was born in the mid-1850s.
