Which group primarily supported the National Republicans during Jackson's era?

The National Republicans, during the era of Andrew Jackson, primarily found their support among bankers, merchants, and large landowners. This group was aligned with a more centralized federal government and often favored economic policies that would benefit commerce and banking, reflecting their interests in a stable financial environment. They opposed Jackson's populist approach, which emphasized agrarian interests and the rights of the common man. The National Republicans, who included figures like John Quincy Adams and Henry Clay, promoted policies such as the American System, which aimed to improve infrastructure and support a national bank, appealing to those who stood to gain economically from such measures.

The other groups mentioned, such as small farmers, labor unions, and common workers, were generally more supportive of Jackson and his Democratic Party, which championed their interests and often pushed back against the elite merchant and banking interests represented by the National Republicans.
