Editing Cardiff Rugby (section)

====Between the wars====
The First World War certainly had some effect on the club – Johnnie Williams died in the first weeks of the Battle of the Somme, and many other players returned wounded or simply too old to play rugby. Cardiff were forced to turn to younger talent for their team. [[Jim Sullivan (Welsh rugby league)|Jim Sullivan]] was a prime example of this, making his first appearance for Cardiff at the age of 16 in October 1920, and went on to make 38 appearances over the rest of the season. In December 1920, just after his 17th birthday, he became the youngest player to ever appear for the Barbarians. However, in June 1921 he signed for professional rugby league club Wigan, beginning a new trend of Welsh union players "going north" to play rugby league.<ref>{{cite web|url=http://www.cardiffrfc.com/Page/Content/1154|title=Cardiff RFC Season Review 1920 - 1921 - Cardiff RFC|website=Cardiffrfc.com|access-date=9 May 2018|url-status=dead|archive-url=https://web.archive.org/web/20140717055246/http://www.cardiffrfc.com/Page/Content/1154|archive-date=17 July 2014|df=dmy-all}}</ref>

In 1922, Cardiff Rugby Club and [[Cardiff Cricket Club]] would form the [[Cardiff Athletic Club]],<ref name="Cricket">{{cite web |title=Cardiff Arms Park – a short History by Andrew Hignell – Cardiff Athletic Club |url=https://cricketarchive.com/Glamorgan/History/Cardiff_Arms_Park/Athletics.html |url-status=dead |archive-url=https://web.archive.org/web/20110522083706/http://cricketarchive.com/Glamorgan/History/Cardiff_Arms_Park/Athletics.html |archive-date=22 May 2011 |access-date=14 May 2008 |publisher=Glamorgan County Cricket Club & CricketArchive |df=dmy-all}}</ref> and then purchased [[Cardiff Arms Park]].<ref>{{Cite web |title=Cardiff's first home |url=https://www.espncricinfo.com/story/cardiff-s-first-home-60134 |access-date=2024-01-22 |website=ESPNcricinfo |language=en}}</ref>

In the 1930s, Scrum-half [[Howard Poole]], although never capped for Wales, was selected to play for the Lions in 1930, as was Ivor Williams in 1938.  The club also won their first unofficial Welsh championship for 28 years in 1937, and managed to retain the title in 1938 and 1939, before the start of the Second World War.
