The Draconians were founded in 1963, receiving special permission to use the Draconians name first used by a Welsh representative side.[2] In their first season in the Cardiff Combination League, they finished as Second Division champions.
The club changed its name to Gabalfa Draconians at about the time that the Llanidloes Road ground was first used for home games (1984–85 season), before reverting to their original name in 2000 when they entered the South Wales Amateur League.[3]
After finishing as runner-up in the South Wales Alliance League Premier Division in 2019–20 and being granted a tier 3 licence by the Football Association of Wales, the club initially failed to gain a place in the new tier 3. However, after the withdrawal and folding of STM Sports, on 3 August 2020 the club was informed that they had been accepted to the new tier 3 Ardal Leagues South West for the 2020–21 season[4] as the highest placed team from the Alliance League who had been awarded a licence.
