In 1814, during the British attempt to capture Baltimore, the bombardment of Fort McHenry inspired Francis Scott Key to write the words to “The Star-Spangled Banner.” During the Civil War, Maryland was a slave state but remained in the Union. Consequently, Marylanders fought on both sides and many families were divided.
Maryland is bounded on the north by Pennsylvania, on the west by West Virginia, on the east by Delaware and the Atlantic Ocean, and on the south, across the Potomac River, by Virginia. It shares a border near the center of the state along the Potomac with Washington, DC. Chesapeake Bay nearly bisects the state, and the counties east of the Bay are known collectively as the Eastern Shore
Maryland's economic activity is strongly concentrated in the tertiary service sector, and this sector, in turn, is strongly influenced by location. One major service activity is transportation, centered around the Port of Baltimore and its related rail and trucking access. The port ranked 10th in the USA by tonnage in 2002. Although the port handles a wide variety of products, the most typical imports are raw materials and bulk commodities, such as iron ore, petroleum, sugar, and fertilizers, often distributed to the relatively close manufacturing centers of the inland Midwest via good overland transportation nets.
Among the popular attractions in Maryland are the Fort McHenry National Monument; Harpers Ferry and Chesapeake and Ohio Canal National Historic Parks; Antietam National Battlefield; National Aquarium, USS Constellation, and Maryland Science Center at Baltimore's Inner Harbor.
