George Hume Steuart was a planter in Maryland and an American military officer; he served thirteen years in the United States Army before resigning his commission at the start of the American Civil War. He joined the Confederacy and rose to the rank of brigadier general in the Army of Northern Virginia. Nicknamed "Maryland" to avoid verbal confusion with Virginia cavalryman J.E.B. Stuart, Steuart unsuccessfully promoted the secession of Maryland before and during the conflict. He began the war as a captain of the 1st Maryland Infantry, CSA, and was promoted to colonel after the First Battle of Manassas.

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.
