Why was Fort Sumter important

It was full of Union weapons
it marked the beginning of the war
it was located in a border state
it marked a willingness to compromise

The most accurate answer is that Fort Sumter marked the beginning of the war. Fort Sumter, located in South Carolina, was an important military installation occupied by Union troops. It was the first battle of the American Civil War, which began on April 12, 1861, when Confederate forces attacked the fort. This event symbolized the escalating tensions between the Northern and Southern states and ultimately led to the secession of several Southern states and the outbreak of the Civil War.
