League was formed in 1946/1947 under the name of “THE SOUTH WALES CORINTHIAN
LEAGUE” with a view to creating a link between local Leagues in SOUTH
WALES & MONMOUTHSHIRE to progress to the WELSH FOOTBALL LEAGUE.
Over the years a great number of Clubs progressed to the Welsh League from this League, many of which are still current members of the Welsh League.
Up to the year 1991, Clubs were entered into the Welsh Football League by invitation and not necessarily by being the Champion Club of the South Wales Amateur League.
In 1991 the FOOTBALL ASSOCIATION OF WALES inaugurated a PYRAMID STRUCTURE and the F.A. of Wales recognising the qualities of the League, recommended that it should be included in the Pyramid structure.
Currently, at every season end, a PLAY OFF between the League and the South Wales Senior League takes place, with the winner being promoted to the Welsh Football League.
Over recent years, League MEMBER CLUBS have also created a formidable record in the F.A. of WALES TROPHY COMPETITION as follows:-
Since its inauguration, over 125 Clubs have enjoyed membership of the League and CARDIFF CITY and NEWPORT COUNTY both entered teams in the League for SEASON 1948/1949. The League was initially founded with 11 clubs; including Cardiff Corries who now also operate with a team in the Welsh Football League. Taffs Well and Ynysddu Welfare are the League's longest serving Clubs, the former also have a team in the Welsh League. Cardiff Corries and Taffs Well are the only reserve teams in the League. The League expanded to 18 Clubs in 1947/48, and such was its popularity that in 1948/1949 a Second Division was formed with the League membership extending to 31 Clubs. Many of the Clubs provide a “Match Programme” and the League is honoured that BRYNTIRION ATHLETIC won the BEST IN WALES in a programme survey by WIRRAL, and CWMAMAN INSTITUTE have also won awards in recent years.
