Final answer:
Jacksonian democracy promoted a majority's will and suspicion of economic elites, influencing sectionalism by avoiding slavery discussions and emphasizing states' rights and expansionism, thereby fostering divisions between different regions.
Step-by-step explanation:
Jacksonian democracy significantly shaped the era of the common man and the resulting political landscape. Andrew Jackson's emphasis on the will of the majority and suspicion towards the wealthy and powerful played into existing sectional divisions. Jackson's hands-off approach to economic development and pursuit of democratic ideals for white males enhanced sectionalism by avoiding direct confrontation with the issue of slavery, while aiming to stimulate westward expansion and states' rights which were aligned with Southern interests.
The Democratic Party, avoiding slavery, tried to unite Americans on shared commitments to white supremacy and expansionism, rallying support from various geographical sections. However, Jackson's stance on states' rights, exemplified by his approach during the nullification crisis, further entrenched sectional divisions, as his policies were more favorably received in some regions over others. The burgeoning conflict between the interests of different regions laid the foundation for increased sectionalism, eventually culminating in the Civil War.
