Rhys Gryg (English "Rhys the Hoarse") (died 1234), real name Rhys ap Rhys, also known as Rhys Fychan ("The Younger") was a Welsh prince who ruled part of the Kingdom of Deheubarth.
He married Mathilde, the daughter of Richard de Clare, 3rd Earl of Hertford.
In Rhys ap Gruffydd's old age he had a great deal of trouble keeping control of his sons, and a bitter feud broke out between Gruffydd ap Rhys II and Maelgwn ap Rhys. Rhys Gryg formed an alliance with Gruffydd against Maelgwn, then in 1195 joined with another brother, Maredudd, in a conspiracy against their father and captured Dinefwr Castle. Their father however retaliated by capturing both of them and imprisoning them in Ystrad Meurig Castle.
Rhys Gryg reappears in 1204. Rhys ap Gruffydd had died in 1197 and Rhys Gryg's ally Gruffydd in 1201 and Maelgwn had taken possession of most of Deheubarth. In 1204 Rhys made an alliance with Gruffydd's sons, Rhys and Owain, and drove Maelgwn out of Ystrad Tywi which was then shared between them, with Rhys Gryg getting the Cantref Mawr. By 1211 Rhys had fallen out with his nephews, who were supporters of Llywelyn the Great and intervened on behalf of King John of England, attacking and capturing Llandovery from them with the help of English Royal troops. After John has forced Llywelyn to give up all his conquests outside the core area of Gwynedd, Rhys joined with Maelgwn to eject his nephews from the remainder of their lands. However when King John built a castle at Aberystwyth, Rhys and Maelgwn changed sides, attacked the castle and burnt it. In 1212 Rhys attacked and burnt Swansea.
Defeat, flight and capture
The sons of Gruffydd ap Rhys, Rhys and Owain, had now made their peace with King John and gone over to the English Royal side. In 1213 and English army led by Falkes of Breauté was sent to strip Rhys Gryg of his lands and give them to his nephews. Rhys was defeated in a battle at Llandeilo and was forced to flee to Ceredigion to seek the protection of his brother Maelgwn. Later in the year he was captured by the English and imprisoned at Carmarthen.
Release and revolt
In 1215 however, the sons of Gruffydd ap Rhys turned against the King and made an alliance with their uncle Maelgwn. The English released Rhys Gryg in the hope that he would start a civil war but instead Rhys joined forces with Llywelyn the Great, and he, along with Maelgwn and the sons of Gruffydd ap Rhys were with Llywelyn in the attack which captured many castles in South Wales in December of that year. At the parliament held by Llywelyn at Aberdovey in 1216, Rhys Gryg was allocated Cantref Mawr and Cantref Bychan and other lands.
Rhys supported Llywelyn during the remainder of his career. In the war of 1231 he joined with his brother Maelgwn's son, Maelgwn the Younger, to burn Cardigan and then capture the castle for Llywelyn. In 1234 he joined with Maelgwn Fychan again to attack Carmarthen, but received wounds of which he died at Llandeilo Fawr shortly afterwards.
Burial and succession
He was buried in St. David's Cathedral and was succeeded by his son Maredudd. He left another son known as Rhys Mechyll (d.1244), who had a son named Rhys Fychan ap Rhys Mechyll and a daughter named Gwenllian Mechyll, who eventually became his heiress and married Gilbert Talbot (d.1274), grandfather of Gilbert Talbot, 1st Baron Talbot (d.1345/6). The ancient arms of the House of Dinefwr Gules, a lion rampant or within a bordure or were inherited and assumed in lieu of the Talbot paternal arms as "arms of alliance" on marriage to a great princess.
