The great religious revival of 1904[3] spread throughout South Wales led by lay preacher Evan Roberts.

Like many teams in South Wales, players who quit rugby to follow a more godly code resulted in the eventual dissolution of the club in 1904.

One of the club's proudest moments came in 1939 when former player Cyril Challinor, now playing for Neath, was chosen to represent Wales against England.

In 1971, Crynant's secretary since 1927, Rhys Emlyn Williams, was elected to the post of Welsh Rugby Union President coinciding with the club's upturn in fortunes.

In the late 1960's the formation of a Youth Side and the extension of the clubhouse meant far more social events and very often two games at home on a Saturday.

Crynant produced a dozen Youth & Schools Internationals during this period and the advent of the local O.G.Davies competitions meant further successes.

A year later, the history books were nearly re-written when visitors Llanelli scraped a 14-9 win in an epic Welsh Cup game, Cryant coming desperately close to a try in the dying minutes.

The emblem of Crynant Rugby Club includes a picture of a white horse that is believed to relate to the mountain of March Hywel that overlooks the village.
