What was a direct consequence of the Battle of Fort Sumter in terms of state alignment?

The Battle of Fort Sumter, which occurred in April 1861, marked the beginning of the American Civil War after Confederate forces fired on the Union-held fort in Charleston Harbor, South Carolina. This event had significant repercussions on state alignment regarding the conflict.

The correct answer is that it led to the joining of four more states to the Confederacy. Following the battle and the subsequent call for troops by President Lincoln, several states that had previously been undecided or remained in the Union chose to secede and entrench themselves alongside the Confederacy. These states included Virginia, Arkansas, Tennessee, and North Carolina, which formally joined the Confederate States of America.

The shifting allegiances after Fort Sumter highlighted the escalating tensions between the North and South, as well as the response of border and slave states to the aggression exhibited by both sides. This important alignment of states was crucial in shaping the theater of war and the Southern war effort in its early stages.
