Editing Cardiff Rugby (section)

=== Origins ===
The first reliably recorded Rugby club in Cardiff were Tredegarville,<ref name="cf10rugbytrust.org"/> who began playing around 1870. By 1874 a team named Glamorgan FC had been formed and in 1876 they merged with Cardiff Wanderers to form the Cardiff Football Club.<ref name="cf10rugbytrust.org"/> At the time, association football was little known in South Wales and it was not until the 20th century that the team became known as Cardiff Rugby Football Club.

Cardiff FC played their first fixture on 2 December 1876,<ref name="Davies19">Davies (1975), pg 19</ref> versus Newport at Wentloog Marshes. In 1881, Cardiff beat [[Llanelli RFC|Llanelli]] to win the South Wales Challenge Cup, though the tournament was scrapped soon after due to persistent crowd trouble.
