Overview: The flag of Maryland is a state emblem that visually derives from the heraldic banner associated with George Calvert, 1st Baron Baltimore (1579–1632). It was formally adopted by the Maryland General Assembly in 1904 and has since been used at official events, on public buildings, and as a widely recognized cultural motif across the state. It is often remarked for its bold colors and unusual origin in English heraldry.

Design elements

  • The field is divided into alternating quarters: one pattern uses a black and gold (yellow) design drawn from the Calvert family arms.
  • The contrasting quarters display a red and white cross pattern derived from the Crossland family, related to Calvert by marriage.
  • Heraldic forms and color arrangement give the flag a distinctive checkerboard and cross combination that is easy to recognize at a distance.

History and development: The two motifs date from 17th‑century English heraldry and were used informally in the Maryland colony. During the American Civil War, allegiance within the state was divided; supporters of the Union tended to display the black-and-gold Calvert pattern, while Confederate sympathizers used the red-and-white Crossland pattern. After the war, combining both designs into a single flag became a symbol of reunion and reconciliation, which influenced the legislature's decision to formalize the combined banner in the early 20th century.

Uses and cultural importance: Beyond its official capacity on government buildings and documents, the Maryland flag appears on license plates, university and athletic uniforms, local signage, and popular apparel. The distinctive palette and pattern have become a regional trademark, used by businesses, cultural events, and community organizations to signify Maryland identity.
