Maryland in the American Civil War: Maryland’s House of Delegates votes not to secede from the Union.

During the American Civil War (1861–1865), Maryland, a slave state, was one of the border states, straddling the South and North. Despite some popular support for the cause of the Confederate States of America, Maryland did not secede during the Civil War. Governor Thomas H. Hicks, despite his early sympathies for the South, helped prevent the state from seceding.
