Baltimore's Marching Ravens are the official marching band of the Baltimore Ravens American football team.
They were founded as The Baltimore Colts Marching Band on September 7, 1947, and have continuously operated ever since, supporting four separate football franchises. The band first supported the original Baltimore Colts from 1947 to 1950, but continued to operate even after the franchise disbanded in 1950. After a new Baltimore Colts franchise was established in 1953, the band became associated with the newly founded team.
The band endured a second relocation when the Colts moved to Indianapolis in the middle of the night in 1984, leaving Baltimore without a team for eleven years but never disbanded.
The band became attached to the Canadian Football League Baltimore CFL Colts/Baltimore Stallions during the league's United States expansion team experiment years between 1994 and 1995. Then in 1996, the band became attached to a fourth franchise when the Cleveland Browns relocated to Baltimore in 1996 to become the Ravens.
