Why was Fort Sumter important?

1. It was full of union weapons.
2. It marked the beginning of the war.
3. It was located in a border state.
4. It marked a willingness to compromise.

All of the given options are important factors in understanding the significance of Fort Sumter, but option 2. "It marked the beginning of the war" is the most accurate answer.

Fort Sumter is historically significant because it was the site of the first shots fired in the American Civil War. On April 12, 1861, Confederate forces attacked the fort, which was held by Union troops. This event marked the formal start of the Civil War, as it was the first time that the Confederacy had initiated military action against the Union. The attack on Fort Sumter demonstrated that diplomatic efforts to resolve the growing tensions between the North and South had failed, and war was now inevitable.
