Final answer:
The Republican Party was created during the second party system, where the prominent political factions were Democrats and Whigs. The second party system started in the late 1820s and lasted until the mid-1850s, with the Republican Party emerging as a major force in the 1850s.
Step-by-step explanation:
The creation of the Republican Party occurred in the second party system, which began in the late 1820s and lasted until the mid-1850s. During this period, the primary political parties were the Democrats and the Whigs. The Republican Party emerged in the 1850s as a major political force, and it was not present in the first party system, which involved the Federalists and the Democratic-Republicans, nor in the third or fourth party systems that followed.
Test Yourself: The Second Party System consisted of the Democrats and Whigs. The election of 1828 brought in the first presidency of the Democrats, with Andrew Jackson. The platform of the emerging Republican Party in the mid-19th century emphasized the opposition to the expansion of slavery into the new territories and is quite different from the erstwhile Federalist or Democratic-Republican parties.
