Frederick has played a role in many historical events, but perhaps none more important than the American Civil War. Located along the Mason Dixon Line, Frederick County was the site of two crucial events, the Battle of South Mountain and the Battle of Monocacy. Parts of the county were alternately occupied by troops from both the union and confederate sides in the days before the nearby battles of Antietam and Gettysburg. In the days after these battles, Frederick became a major hospital center. Many of Downtown Frederick's historic churches were used as a place to heal the wounded and are still standing today.
