Maryland Flag Spiral Notebook

The black and gold design on the flag is the coat of arms from the Calvert line. It was granted to George Calvert as a reward for his storming a fortification during a battle (the vertical bars approximate the bars of the palisade).[citation needed] The red and white design is the coat of arms of the Crossland line, the family of Lord Baltimore's mother, and features a cross bottony with the red and white sides of the cross alternating. Since George Calvert's mother was an heiress, he was entitled to use both coats of arms in his banner. It is one of only four U.S. state flags that does not contain the colour blue (the other three being Alabama, California, and New Mexico). It is also the only US state flag to be directly based on English heraldry, although the flag of Washington, D.C. is a modification of the coat of arms of George Washington's family.
