Maryland, often called The Old Line State, earned its nickname from the Maryland Line, a regiment that served courageously in the Revolutionary War. The state is a patchwork of diverse environments, from the Appalachian Mountains to the Chesapeake Bay, known for its blue crabs and oysters. Maryland's history is rich, from its founding as a haven for Catholics to its key role in the War of 1812, and it continues to be a leader in science, particularly with institutions like the Johns Hopkins University.
