What event was the “final straw” that began the secession of states

Answer 1

The final straw that began the secession of states was the election of Abraham Lincoln as President of the United States in 1860. Many Southern states, fearing Lincoln's anti-slavery stance, saw his election as a threat to their way of life and a violation of their states' rights. This ultimately led to the secession of several Southern states and the formation of the Confederacy.
