Why was secession necessary?

Secession was seen as necessary by certain states, particularly in the South, as a means to preserve their economic interests, social systems, and political autonomy, especially in the context of slavery. Many believed that their rights as states were being undermined by federal policies and the growing influence of anti-slavery sentiments in the North. This led to the belief that secession was the only way to protect their way of life and assert their sovereignty. Ultimately, this decision culminated in the Civil War, as the federal government sought to maintain the Union.
