Although an amateur North Wales rugby representative side had existed for over 50 years, Gogledd Cymru was established by the North Wales Rugby Council, in February 2007, in response to the WRU approved strategic plan for the development of rugby union in the region. This aimed to achieve a north Wales side playing in the Welsh Premier Division by 2010–11 In their first season Gogledd Cymru reached the final of the Welsh Counties Cup.
For the 2012–13 season, the team were entered into WRU Division One East, playing a full season of games against teams from South East Wales. RGC finished the season at the top of the table, earning promotion to the Welsh Championship for 2013–14.
RGC's first season in the Welsh Championship saw them spend much of the season in second place to a dominant Ebbw Vale only to drop to third in the last game by losing to Cardiff Met 36–24. Several RGC players were selected and played in the Wales side for the 2014 U20 Six Nations, with the home games hosted at RGC's Eirias Park stadium.
