The team's official colors of red, white, black, and gold have been in use in some combination since the 1920s and are taken from Maryland's state flag, and the Terrapins nickname — often abbreviated as "Terps" — was adopted in 1933 after a turtle species native to the state.

This is a List of United States Senators from Maryland.  Maryland ratified the Constitution on April 28, 1788, becoming the seventh state to do so.  To provide for continuity of government, the framers divided Senators into staggered classes that serve six-year terms, and Maryland's Senators are in the first and third classes.  Before the passage of the Seventeenth Amendment to the United States Constitution in 1913, which allowed for direct election of Senators, Maryland's Senators were chosen by the Maryland General Assembly.  Until the assembly appointed George L. Wellington of Cumberland in 1897, Senators in class 3 were chosen from the Eastern Shore while Senators in class 1 were chosen from the remainder of the state. The Maryland Senate is the upper house of the Maryland General Assembly, the bicameral state legislature of the U.S. State of Maryland.  The Senate comprises 47 elected members from 47 single-member senatorial districts in the state.  The Maryland General Assembly is considered one of the oldest continually operating legislative bodies in the United States.  The current delegation consists of 35 Democrats (D) and 12 Republicans (R). The official flag of the state of Maryland consists of the heraldic banner of George Calvert, the first Lord Baltimore (1579–1632).  The flag was officially adopted by the Maryland General Assembly in 1904. The Maryland General Assembly elections of 2010 took place on November 2, 2010, to choose the Delegates and Senators of the Maryland General Assembly.
