The Welsh League was the first club rugby league competition in Wales. Its inaugural season was in 1908/09 when four additional teams were formed to join Ebbw Vale RLFC and Merthyr Tydfil RLFC, which allowed a league tournament to take place. The Welsh League ran for just two seasons, after three of the teams, Aberdare, Barry and Mid-Rhondda left the Northern Union and ceased playing rugby in the first season; followed by the collapse of Treherbert in 1910. Both seasons were won by Ebbw Vale.
