GCRD was founded in January 2006 by Ginger Clark and Andrea Moore, known as "Helen of DesTroy" and "Cyn Vicious". The league initially formed two teams, the Queens of Hearts and the Aces of Spades, that later became the Rude Girls and Damage Inc. After a decrease in league membership, the two teams became one for several years. Steady growth led to a return of the two-team structure for the 2014 season. The new team names are The Purple Reign and The Violet Femmes.
In the summer of 2016 as Gem City Rollergirls, Gem City rebranded in June 2016 and further expanded to include three intraleague home teams, who will play one another during the 2016-2017 off season. The home teams are: The Bully Frogs, Snark Attack, and Murder Squad.
GCRD initially joined the Women's Flat Track Derby Association (WFTDA) in July 2007. However, after struggling to maintain a sufficient number of eligible skaters, GCRD was unable to play any fully sanctioned bouts during the 2008 season. During 2009 several long-standing skaters left the league, which also incurred increases in rink costs; however the league survived. In 2010, the league reverted to the status of apprentice members of the WFTDA. The league grew each year following and, during the 2013 boot camp, nearly doubled in size to a total of over fifty skaters. GCRD earned its full WFTDA status back for the 2014 season and has been climbing the WTFDA ranks ever since.
