Final answer:
By the end of Andrew Jackson's administration, a new Republican Party had not yet been established; rather, the Whig Party had emerged as the opposition to Jackson's Democratic Party, marking the Second Party System's formation in American politics.
Step-by-step explanation:
By the end of Andrew Jackson's administration, a new Republican Party had assumed the role of loyal opposition. This marked the evolution of the Second Party System in American politics.
The Democratic Party, representing the ideals of Jackson and advocating for the common people, emerged in 1828 and experienced significant growth. The National Republicans, who later evolved into the Whig Party, represented the faction that favored economic development and a stronger national government. Throughout Jackson’s presidency, the seeds of future political realignment were sown, as these two parties began to solidify their platforms and approaches to governance.
By the time Jackson left office, the nation had witnessed the formation of a party distinctly separate from the Democrats, whose members had broader economic interests and supported more federal involvement in the economy the Whig Party. This newly established party system would dominate the American political landscape until the rise of the Republican Party in the 1850s.
