The league was established in 2005, when Caroline Donaghy returned to Baltimore from Houston, where she had skated with the Space City Roller Girls, and began promoting the intention to start a league in Baltimore. The first public Charm City game was held in 2006 at Skateland in Putty Hill. Upon the league's formation, it comprised four teams: the Junkyard Dolls, the Mobtown Mods, the Night Terrors and the Speed Regime. As early as 2008, games were being held at the Fifth Regiment Armory in Baltimore, and by 2009, the league was holding games at Du Burns Arena in Canton before sellout crowds of 2,000 fans. As of 2017, Charm City has three travel teams: the All-Stars represent the league in WFTDA competition, and Female Trouble and the Trouble Makers are B and C teams, respectively. A three-team home league features the Dundalk Deviants, Hampden Hons and Pigtown Butchers. The All-Stars are known for wearing helmets that feature elements of the state flag of Maryland, which they first donned in 2008. Charm City Roller Girls operates as a limited liability company. League member Joy Collision was a member of Team USA, representing the United States at the 2011 Roller Derby World Cup.
