Answer:
The South feared the election of Abraham Lincoln and the Republican party for several reasons:
Opposition to Slavery: Abraham Lincoln and the Republican party were against the expansion of slavery into new territories. While Lincoln did not advocate for immediate abolition, his election signaled a growing sentiment against slavery, which threatened the economic and social structure of the Southern states heavily reliant on slave labor.
Economic Impact: Slavery was deeply intertwined with the Southern economy, particularly in the agricultural sector. The Southern states feared that if slavery were to be abolished or restricted, it would have severe economic repercussions, including a decline in profits from agriculture and a potential loss of labor force.
Political Power: The election of Lincoln meant that the Republican party, which was viewed as hostile to Southern interests, would have control over the executive branch of the federal government. This raised concerns that the Republican party would implement policies and legislation that would undermine the power and influence of the Southern states in national affairs.
States' Rights: The South valued states' rights and autonomy, and they believed that a Republican president like Lincoln would encroach on their rights, particularly concerning issues related to slavery and the expansion of federal power. They feared that the federal government would limit or eliminate their ability to determine their own laws and policies, including the institution of slavery.
These fears and concerns ultimately played a significant role in the secession of Southern states from the Union, leading to the American Civil War.
