Cymru South
The Cymru South is a regional football league in Wales, covering the southern half of the country. It initially had clubs with semi-professional status. Together with the Cymru North, it forms the second tier of the Welsh [football league system].
The first year of its operation was in 2019–20 with the Football Association of Wales owning and administering the tier 2 leagues for the first time. These changes followed on from a review of the Welsh Football Pyramid. Prior to 2019, the equivalent league was the Welsh [Football League Division One], covering South Wales.
