In the early years of organised football in Wales, football was very much the sport of North Wales rather than the rugby union playing south – the FAW was founded in Ruabon, near Wrexham in 1876, and Wrexham remained the site of the FAW's head office until 1986; it was not until 1912 that a southern team, Cardiff City, won the Welsh Cup for the first time.
Until 1995, Welsh clubs playing in the Welsh or English leagues were invited to play in the Welsh Cup. On occasion some English clubs were also invited to participate. However, in the event of an English club winning the Welsh Cup, they were not allowed to progress to the European Cup Winners' Cup. Instead, the best placed Welsh club in the Welsh Cup competition would take the European place.
From 1996 to 2011, only clubs playing in the Welsh football league system were allowed to enter the Welsh Cup. This rule excluded the six Welsh clubs who played in the English football league system: Cardiff City, Colwyn Bay, Merthyr Tydfil Town, Newport County, Swansea City and Wrexham. On 20 April 2011, the Football Association of Wales invited these six clubs to rejoin the Welsh Cup for the 2011–12 season, but only Merthyr Town, Newport County and Wrexham accepted. In March 2012, UEFA stated that Welsh clubs playing in the English football league system could not qualify for European competitions via the Welsh Cup but they could qualify via the English league and cup competitions, hence they were subsequently again excluded from the Welsh Cup.
Between the 1961–62 and 1984–85 seasons, the final was played as a two-leg match, originally on a points basis rather than aggregate score. In the 1985–86 season, it reverted to a single game, to be decided by extra time and penalties as necessary.
Shrewsbury Town hold the record for the most times an English team has won the Cup, a record that will remain unbroken owing to the fact that English teams have not been allowed to compete in the cup since 1995. The last English winner of the Welsh Cup was Hereford United in 1990.
