Answer:
the Presidential election
Step-by-step explanation:
The presidential election.
Abraham Lincoln was elected on a purely sectional vote, with no Southern votes cast in his favor. This signaled to many Southerners that the interests of their region, including the institution of slavery, were no longer represented in the national government, and that their views were not taken into account or respected. For many Southerners, this was seen as a betrayal of their trust, and a sign that the federal government was no longer looking out for their interests.
