Cardiff Rugby Football Club was founded in 1876. The club played their first few matches at Sophia Gardens, but soon relocated to Cardiff Arms Park, where they have been based ever since. They built a reputation as one of the great clubs in world rugby largely through a series of wins against international touring sides. South Africa and New Zealand have been beaten by Cardiff. Australia have failed to beat them in six attempts. Cardiff have provided more players to the Welsh national side and British Lions than any other Welsh club.
Cardiff RFC was one of the eleven clubs present at the formation of the Welsh Rugby Union in Neath in 1881 and supplied three players to the first Welsh international team who took on and lost to England earlier that year.
A notable early player was Frank Hancock. A skilful centre, Hancock first played for Cardiff due to an injury to a first regular. At this time, rugby was played with six backs and nine forwards but Hancock's performance so impressed the selectors that for the next game they selected him as a seventh back and selected only eight forwards. The system was soon adopted by the Welsh national team and the seven backs and eight forwards system exists in rugby to this day.
