The American Civil War was a conflict that occurred between the United States and the Confederate States of America in the 19th century on Earth in North America.

Although coming at a time before mankind could learn to resolve disputes without bloodshed, the outcome of the civil war, nevertheless, brought about an end to slavery and oppression. (VOY: "The Q and the Grey")

This statement by Q is odd, as oppression of African-Americans did not end in the United States until long after the Civil War.

After Jonathan Archer restored a damaged timeline, a scene from the American Civil War could be seen in the time stream as the timeline realigned itself. (ENT: "Storm Front, Part II")

General Ulysses S. Grant served as the commanding officer of the Union Armies during the Civil War, a position granted to him by Abraham Lincoln. (TOS: "The Savage Curtain") Colonel Thaddius Riker also fought in the conflict in the Union Army. (VOY: "Death Wish")

During the war, the Union Army utilized observation balloons that were tendered at around six hundred feet high. (TOS: "The Savage Curtain")

During the Q Civil War, Q chose to represent the war by using an illusion of the American Civil War, so that Captain Janeway could comprehend the Continuum. (VOY: "The Q and the Grey")
