What years did the Civil War occur?

The Civil War in the United States is historically recognized as occurring from 1861 to 1865. Starting on April 12, 1861, with the attack on Fort Sumter, it continued until April 9, 1865, when General Robert E. Lee surrendered to General Ulysses S. Grant at Appomattox Court House. This timeframe encapsulates the major events of the war, including significant battles, the issuance of the Emancipation Proclamation in 1863, and ultimately the conclusion of the conflict with the defeat of the Confederate States.

The other options provided do not cover the full duration of the war, which is why they fall short. The first option suggests the war began in 1860, which is inaccurate as the first armed conflict did not commence until 1861. Other choices incorrectly limit the end year to 1864 or start later than the true beginning in 1861. Therefore, the chosen answer precisely aligns with the historical timeline of the Civil War, making it the correct response.
