Due to its location and a desire from both opposing factions to sway her population to their respective causes, Maryland played an important role in the American Civil War. The first fatalities of the war happened during the Baltimore Riot of 1861, and the single bloodiest day of combat in American military history occurred near Sharpsburg, Maryland, at the Battle of Antietam, which provided the opportunity for President Abraham Lincoln to issue his famed Emancipation Proclamation. The 1864 Battle of Monocacy helped delay a Confederate army bent on striking the Federal capital of Washington, D.C..
