Talgarth, United Kingdom

Rhys played a significant part in the implementation (though not the planning) of the final coup against Edward II, and consequently Edward's son, Edward III, was not well disposed towards him; he dispossessed Rhys' heir, and merged the Lordship of Blaenllynfi back into the Lordship of Brecknock (which, with the Lordship of Buellt, eventually became Brecknockshire, centuries later).

During the Jacobite revival, support in Talgarth was strong. The town was a Jacobite hotspot, backing Bonnie Prince Charlie in his attempt to retake the crown for the Stuarts. In 1727 a meeting of local Jacobite sympathisers in Talgarth ended with members having to appear before a local magistrate to explain their actions.

During the Jacobite rising of 1745, Bonnie Prince Charlie had expected the Welsh Jacobites to offer support, but after the Jacobite David Morgan was hanged, drawn and quartered for treason, the Welsh feared persecution. The failure of the Welsh Jacobites to join the House of Stuart prince in Derby was one of the main failures of the Jacobite uprising.

In 1735, Talgarth saw the birth of the Welsh Methodist revival when Howel Harris, probably the most influential person to come from Talgarth, was converted in Talgarth church while listening to a sermon by the Reverend Pryce Davies. The revival would sweep across Wales, leading to the development of one of the most influential Welsh denominations, that of the Calvinistic Methodists. It was at Talgarth that William Williams Pantycelyn converted, leading him to become one of Wales' most important hymn writers. Nearby is Trevecca, the location of the famous college that Harris established. Hywel Harris is buried in Talgarth at St Gwendoline's Church and his tombstone is still visible today. Talgarth is also thought to be the birthplace of the religious poet Jane Cave.
