The action that caused four more states to join the Confederacy was the attack on Fort Sumter in April 1861. This event marked the beginning of the Civil War and prompted Virginia, Arkansas, Tennessee, and North Carolina to secede from the Union and join the Confederate States. The assault galvanized support for secession in these states, as they viewed it as a defense of their rights and way of life.
