Which event marked the beginning of the Civil War in 1861?

• A. The attack on Fort Sumter
• B. The Battle of Gettysburg
• C. The Emancipation Proclamation
• D. The Surrender at Appomattox

Answer: (A)

The event that marks the start of the Civil War is the first armed clash between the United States and the Confederate states. When Confederate forces fired on Fort Sumter in Charleston Harbor in April 1861, the Union garrison surrendered and the conflict escalated into full-scale war. This moment is considered the beginning because it was the first actual fighting between the two sides, after a period of increasing tensions over secession and military mobilization. The other events listed happened later in the war or were actions taken during the war: Gettysburg was a major battle in 1863, the Emancipation Proclamation was issued in 1863 to redefine the war’s purpose, and the surrender at Appomattox occurred in 1865, effectively ending the war.
