Rhys ap Gruffudd ("yr Arglwydd Rhys"), king of Deheubarth

King of Deheubarth; later, Prince of Deheubarth

As a teenager, Rhys participated in several campaigns with his elder brothers. On the death of his brother Maredudd in 1155, Rhys succeeded to a kingdom made up of Ceredigion, Ystrad Tywi, and Dyfed. Rhys submitted to King Henry II in 1157, but there were frequent hostilities between them up until 1171, when Henry decided to throw his support behind Rhys as a check to the growing power of the Marcher Lords. This brought about a peace lasting until Henry’s death in 1189. In that year Rhys renewed his attacks, considering his agreement to have been a personal agreement with Henry rather than an agreement with the English crown. In his last years, Rhys found himself occupied with conflicts between his sons, at one point being briefly imprisoned by Maelgwn, his eldest, but illegitimate, son.

Rhys was the most powerful native ruler in Wales from the death of Owain Gwynedd in November 1170 until his own death. Contemporary opinion of Rhys was almost entirely favourable. (Pryce, ODNB “Rhys ap Gruffudd”)

Events

Date of Birth:1131/2.

This date is given by Pryce (ODNB “Rhys ap Gruffudd”) and by Lloyd (2:475 fn 53). The date is based on Rhys being younger than his brother Maredudd, who died in 1155 in his 25th year. Brut y Tywysogion (Williams pp. 182-183) records Maredudd as dying in 1154 in the 25th year of his age. Annales Cambriæ (Williams p. 46) records that Rhys was Maredudd’s younger brother (“Maredut filius Grifini [filii Res veneno] obiit. Resus vero junior [ejus frater]...”). Rhys’s involvement in military campaigns in the 1140s suggests that he couldn’t be much younger than Maredudd.

Date of Death: 28 April 1197.

This date is given in Brut y Tywysogion (Williams pp. 244-247) and Annales Cambriæ (Williams pp. 60-61). Bridgeman (p. 65), citing Annales Theokesberiæ, gives the date as 24 April (viii. Kal. Maii). Maund (p. 112) gives 28 April 1197.

Date of Burial: 1197.

Place of Burial: the cathedral church of St David’s.

The place is given in Annales Cambriæ (Williams pp. 60-61). Prior to his burial, penance was administered on his corpse “to absolve him from a sentence of excommunication incurred for his complicity in an assault on Peter de Leia, bishop of St David’s, shortly before his death” (Pryce, ODNB “Rhys ap Gruffudd”; Bridgeman pp. 66-67). Bridgeman (pp. 67-68) notes that some accounts state that Rhys was buried at Strata Florida or Istrad Flur.

Relationships

Father: Gruffudd ap Rhys ap Tewdwr (about 1090 - 1137).

This relationship is shown by Bartrum (EVWG, Rhys ap Tewdwr 1; EWGT), and given by Pryce (Acts Table 3), and by Pryce (ODNB “Rhys ap Gruffudd”). Brut y Tywysogion records this relationship. The earliest record of this relationship is in Geraldus Cambrensis (Description of Wales 1:3).

Mother: Gwenllian ferch Gruffudd ap Cynan (died 1136).

This relationship is shown by Bartrum (EVWG, Rhys ap Tewdwr 1; EWGT), and given by Pryce (ODNB “Rhys ap Gruffudd”).

Spouse: Gwenllian ferch Madog ap Maredudd.

This relationship is shown by Bartrum (Rhys ap Tewdwr 4, Bleddyn ap Cynfyn 3, “Plant yr Arglwydd Rhys” note 1), and given by Bridgeman (p. 68), and by Smith (ODNB “Gruffudd ap Rhys”). Giraldus Cambrensis, whose mother was a first cousin of Rhys, in Itinerarium Kambriæ (1:1) describes how Rhys’s wife caused him to change his mind about going to the Holy Land: “...donec uxor ejus, et communi patriæ vitio in quarto gradu cognata, Gwendoloena scilicet Maidoci Powisensis filia, ipsum a nobili proposito, peccatis exegentibus, muliebriter instans penitus avertit.” That is, Rhys’s wife, Gwenllian, daughter of Madog of Powys, was related to Rhys in the fourth degree, after “the common vice of the country.” Gwenllian is said to have married her stepson, Maelgwn Hen, after Rhys’s death.

Concubine: Gwerful ferch Llywelyn.

Children (by Gwenllian ferch Madog):

(Complete source citations for facts about the children on this page are currently outside of the scope of this project. Some doubt exists surrounding some of the facts for some of the children. Most of the information below comes from Bartrum.)

Gruffudd (died 1201) married Matilda de Briouze.

Rhys Gryg (died 1234) married (1) Ellyw ferch Thomas (or Trahaearn); possibly married (2) Matilda ferch Richard, widow of William de Braose; possibly married (3) Gwenllian ferch Elidir ab Owain.

Margred married Gwenwynwyn.

Maredudd Gethin (died 1201) married Gwenllian ferch Hywel.

Gwenllian (died 1236) married (1) Rhodri ab Owain Gwynedd; married (2) Ednyfed Fychan.

Children (by Gwerful ferch Llywelyn):

Maelgwn Hen or Fawr (died 1231) is said to have married his stepmother Gwenllian ferch Madog.

Children (by a daughter of Gruffudd ap Gwyn ap Gwalchmai):

Cynwrig (died 1237).

Children (by Gwenllian ferch Maredudd):

Cadwaladr Lwgr (1173 - 1186?). Brut y Tywysogion records that the birth of a son to Rhys and Gwenllian in 1173 caused widespread death to people and animals (presumably due to heaven’s displeasure at the incest involved). Bartrum (“Plant yr Arglwydd Rhys”) notes that Brenhinedd y Saeson names this son Meurig. Bartrum (Rhys ap Tewdwr 3) puts a question mark after the 1186 death date (recorded in Brut y Tywysogion), perhaps expressing doubt that the Cadwaladr who died in 1186 was the same person as the child born in 1173.
