Baltimore County, Maryland is a populous jurisdiction in the U.S. state of Maryland surrounding but independent from the city of Baltimore.

During the American Revolutionary War and the War of 1812, local militia and militia leaders connected to figures like Horatio Gates and events such as the Battle of North Point influenced regional defense. The county industrialized in the 19th century with rail projects like the Baltimore and Ohio Railroad spurring growth in towns linked to mills and shipyards that later supplied efforts in the American Civil War and the World War I and World War II mobilizations. Suburbanization after World War II brought residential expansions, while legal and political changes mirrored national trends exemplified by cases invoking provisions of the Fourteenth Amendment and shifts seen in counties across the United States.
