Sac City Rollers was founded by two friends, Christine Galindo, known as "Devil Doll", and Nicole Kennedy, known as "Loco Coco". They saw the
Rollergirls television show, and immediately decided to form a local league. Within a couple of months, it had sixty skaters, and it was playing bouts before the end of the year. Meanwhile,
Sacred City Derby Girls was founded in late 2006 by some former members of the Sac City Rollers. In October 2007, Sacred was accepted as a member of the
Women's Flat Track Derby Association (WFTDA), announced by the WFTDA in December 2007. By 2010, the league was attracting an average of 850 fans to its intraleague bouts, Sac City was accepted into the
Women's Flat Track Derby Association Apprentice Program in April 2011, and became a full member of the WFTDA in June 2012. Sacred City served as the host league of a
WFTDA Division 1 Playoff in 2014. In October 2017, Sac City co-announced with Sacred City Derby Girls that both leagues would merge for 2018, to continue under a to-be-determined name. The announcement was signed by Director members of each league, and posted on each league's website and social media. The merged organization's new name of Sacramento Roller Derby was announced on January 1, 2018. At the time of the merger with Sacred City, Sac City consisted of three teams which competed against teams from other leagues, the Capital Punishers (A team), Folsom Prison Bruisers (B team) and River City Regulators (C team), and a
junior roller derby team for co-ed skaters aged 8–17. Also at the time of the merger, Sacred City consisted of two competitive travel teams, the Sacrificers and the Disciples, and three home teams, The Donna Party, Midtown Maulies, and The Roseville TrainWreckers. ==WFTDA competition as Sac City Rollers==
