The American Civil War (1861 – 1865) was an armed military conflict in the United States of America. The war began when the Southern states elected to secede from the rest of the country in 1861 to form the Confederate States of America for multiple reasons. The war ended four years later with the victory of the northern states.
Several causes, such as the issues of states' rights and slavery, led to the conflict, which eventually culminated with the assassination of President Abraham Lincoln after the war's end by the Templar-affiliated John Wilkes Booth, who in turn was tracked down and killed by Assassins.
The American Civil War was a point of interest for the Animus Project, and a number of Subjects chosen for it, including Clay Kaczmarek and Desmond Miles, had ancestors who had participated in the conflict. Additionally, Abstergo Entertainment supervisor Melanie Lemay also had a great-great-grandfather who was known to have come into contact with Lincoln a number of times as a Union soldier during the conflict.
The Assassin Varius, lived in New York City during the civil war. In 1863, the mentor tasked Varius to steal a Dagger of Eden and handed it to General Ulysses S. Grant, the dagger managed to reach General Grant.
