Mid-State was founded in June 2010, with practices starting following try-outs in August. It played its first public bout in June 2011, and by 2013 was attracting up to 200 fans to each bout. However, it suffered a setback in April 2013 when its winter practice venue closed.

The league was accepted as a member of the Women's Flat Track Derby Association Apprentice Programme in July 2012, and became a full member of the WFTDA in June 2013.
