Southerners resisted the increased tariff in 1829 primarily because they believed it benefitted one section of the country, particularly the Northern states and their industrial interests, while harming the agricultural economy of the South. Here are some key reasons behind their resistance and the argument for nullification:
1. **Economic Impact**: The South was predominantly agrarian and relied heavily on the export of crops like cotton. They argued that high tariffs increased the cost of imported goods, making it more expensive for them to purchase what they needed while they received little benefit from the tariffs.
2. **Sectionalism**: The tariffs were viewed as favoring Northern industrialists at the expense of Southern agricultural producers. The Southerners felt that the government was prioritizing Northern economic interests, which bred resentment and a feeling of political disenfranchisement.
3. **Nullification Doctrine**: Many Southern leaders, most notably John C. Calhoun, advanced the idea of nullification—the belief that states had the right to nullify federal laws they deemed unconstitutional. They argued that the 1829 tariff was unjust and harmful to their economy and therefore should not be enforced within their borders.
In summary, while there were several arguments presented, the prevailing sentiment among Southerners was that the tariff imposed an unfair economic burden on them and that it favored Northern industry, leading them to seek ways to nullify it.
