Ebbw Vale NUFC was formed in July 1907 and joined the Northern Union at the beginning of the 1907/08 season. The club’s first Northern Union game was played on the 7th of September 1907 away at Keighley. Ebbw Vale lost the game by 26 points to 3.

At the end its first season in the Northern Union Ebbw Vale finished next to bottom of the league with just six wins and two draws from its thirty league games. However, after that disappointing first season Ebbw Vale’s playing record slowly began to improve and a number of its players received International recognition including Thomas Henry Jenkins who became the first player from a Welsh club to be selected for a Great Britain Lions Tour. In 1908/09 the Valians managed to finish in mid table in the Northern Union and also win the inaugural Welsh League. Ebbw Vale finished top of the  Welsh League again in 1909/10, but unfortunately at the beginning of the 1910/11 season, with only two Welsh clubs left in the Northern Union, the Welsh League was abandoned.
