John Wilkes Booth wrote in his diary that he shouted "Sic semper tyrannis" after shooting U.S. President Abraham Lincoln on April 14, 1865, in part because of the association with the assassination of Caesar. The phrase was also in the pro-Confederate Civil War song "Maryland, My Maryland", which was popular at the time with Southern sympathizers in Maryland, such as Booth. The song, containing the phrase, was the official state song of Maryland from 1939 until 2021. In May of 2021, Governor Larry Hogan signed a bill to remove its status as state song without a replacement.
