Biography

Name

• Madog ap Maredudd^[1] or, in English, Madoc, son of Meredith
• Madog ap Maredudd ap Bleddyn ap Cynfyn ^[2]
• Madawc ou Powis-Vadawc

Birth Year Estimation

A birth year of 1091 is estimated. Wolcott estimates his birth as 1098. ^[3]

His specific place of birth is unknown, however, Mathrafal is most likely. Mathrafal, in the cantref of Caereinion, near today's Welshpool in Powys, Mid Wales, was the original capital of the Kingdom of Powys and the seat of its kings and princes from its founding in the 9th century until 1160 and then of Powys Wenwynwyn until 1212, when it was abandoned after desctruction by Llywelyn ap Iorwerth (llywelyn the Great) of Gwynedd. ^[4] It is located on the banks of the River Banwy, just above its confluence with the river Vyrnwy, about 5 km (3 miles) NE of Llanfair Caereinion and 10 km (6 miles) NW of Welshpool on the A495 at its junction with the B4389. Mathrafal is associated with Bleddyn ap Cynfyn, Maredudd ap Bleddyn, Madog ap Maredudd, Owain Cyfeiliog, and Gwenwynwyn ap Owain. Mathrafal today is a ruin with mainly earthworks remaining. Ithas been excavated since 1991 by the University of York. Excavations by the University of York around 1991 found an iron and bronze figurine of St Gwynllyw (or Woolos the Warrior) in a cavity in a window base.

Parentage

Madog was the son of Maredudd ap Bleddyn ap Cynfyn ^[1]

The medieval text Rhandiroedd Powys, which dates from the 1490s or earlier, records his parents as "Meredudd ap Bleddyn ... arglwydd holl Bowys" and "Hynvdd verch Einvdd".^[5]

Wolcott shows Madog (born, say, 1098, obit 1160) the son of Maredudd, (born, say, 1065, obit 1132) in turn the son of [?] Cynfyn (obit 1075). ^[3]

1132 Reign

Madog ap Maredudd was prince of Powys Fadog.^[6]

He succeeded his father in 1132.^[1][7][8]

The medieval text Rhandiroedd Powys, which describes the division of Powys amongst the descendants of Bleddyn ap Cynfyn, records that Madog and his brother Gruffudd divided Powys between them ("Madoc a Grvffudd, ar meibion hynn a ranassant Bowys rryngthvn ylltav").^[5] However, his brother Gruffudd had died in about 1328.^[7]

Madog was the last of his dynasty to rule as king over the whole of Powys, including, for a time, the Fitzalan lordship of Oswestry.^[1]

When his father died in 1132 as lord of all Powys, Madog's influence stretched from Plynlimmon to the gates of Chester, and from Bangor (Iscoed) to the extremity of Meirionydd.^{[citation needed]}

Marriage to Susann of Gwynedd

Madog ap Maredudd married Susanna ferch Gruffydd ap Cynan.^[1] She was the daughter of Gruffydd ap Cynan, King of Gwynedd and his wife Angharad of Deheubarth.^[7]

The medieval text Rhandiroedd Powys records his wife as "Susanna verch Gruffudd ap Kynan".

Stewart Baldwin asserts that Madog's wife is unknown; that she was possibly Susanna ferch Gruffudd ap Cynan, but that since Madog was known to have had children with other women, it is not possible to know which woman was the mother of his children. ^[6]

Marriage to Arianwen

He married second Arianwen ferch Moriddig Warwyn ^[2]

Mistress: Efa

Madog is also shown in some genealogies as the husband of Efa (Eirian) ferch Madog. She apparently was a mistress of Madog, but not married to him. She has been delinked as a spouse but remains mother of some of Madog's children.

Madog had two known mistresses. ^[2]

1141 Battle of Lincoln

Threatened by the building of the castle of Tomen-y-Rhodwydd at the southern end of the Vale of Clwyd, Madog, in alliance with Ranulf, earl of Chester, unsuccessfully challenged Owain's advance, losing, for a time, the control of his lands in Iâl. ^[1]

He is recorded as taking part in the Battle of Lincoln in 1141 in support of the Earl of Chester, along with Owain Gwynedd's brother Cadwaladr ap Gruffydd and a large army of Welshmen. ^[9]

To combat Owain Gwynedd's advances into Powis, Madog first allied with Ranulf, earl of Chester. It failed. His later alliance with Henry II was successful.^[1]

1149 Relations with England and Gwynedd

His main pre-occupation, particularly between the yeas 1149-57, was the defence of Powys against the aggression of Owain Gwynedd. ^[1]

In 1149, he built the castle of Oswestry and gave the commote of Cyfeiliog to his nephews Owain and Meurig, the sons of his brother Gruffudd ap Maredudd.^[10][7]

He was prince during the reign of King Stephen, when the Welsh shed English and Norman control. In 1149 he rebuilt the castle at Oswestry, an area not controlled by the Welsh for about a century. In 1156 he built the stronghold of Caereinion.^[2]

In 1149 Madog was able to rebuild Oswestry castle a fortress of William Fitzalan. It would seem likely that he had gained both the fortresses of Oswestry and Whittington in 1146.^[9]

1149 Defeat by Gwynedd

However, he had to assume a policy of good relations with the English as he resisted the influence of Gwynedd, which bordered on Powys from Machynlleth to Chester. Owain Gwynedd brought pressure on Powys, in part by bulding a castle at Ial (Yale), and led Madog to an alliance with Ralph, Earl of Chester. However, Owain won the ensuing battle at Consillt, near Flint. ^[2]

At this time the King of Gwynedd, between 1149 to 1150, Owain Gwynedd was exerting pressure on the borders of Powys, despite the fact that Madog was married to Susanna, Owain's sister. Madog made an alliance with Ranulf, Earl of Chester, but Owain defeated them at Coleshill in 1150 and took possession of Madog's lands in I‰l (English="Yale"].

1157 Support for Henry II's Invasion

In 1157 Madog stoob by while King Henry I of England marched against Owain Gwynedd, who had organized Welsh national resistance against the English, and during this action Madog's brother, Iorwerth Goch, destroyed the castle at Ial.

In 1157 when King Henry II of England invaded Gwynedd he was supported by Madog, who was able to regain many of his Welsh lands. Even so he retained the lordships of Oswestry and Whittington. In 1159 Madog would seem to have been the Welsh prince who accompanied King Henry II in his campaign to Toulouse which ended in failure. Returning home to Wales Madog died about 9 February 1160 in Whittington Castle. He was buried soon aftwerwards in the church of St. Tysilio at Meifod, the mother church of Powys.^[9]

This loss was retrieved in 1157 when Henry II, with Madog's support, made a decisive assertion of authority in North Wales. When Madog died three years later he was still friendly with his powerful patron. ^[1]

1160 Death and Burial

Madog ap Maredudd died about 1160. ^[1][6]

Brut y Tywysogion records for 1159: "The ensuing year died Madog, son of Maredudd, lord of Powys, ... and at Meivod, where his burial place was, he was honourably interred."^[11][7]

In 1161, the Annales Cambriæ recorded: "Annus MCLXI. Madoc [filius Maredut] Powysorum princeps obiit.^[12][7]

He was buried in the mother-church of Powys — St Tysilio at Meifod.^[1]

Praises sung by poets

His praises were sung by the leading poets of the day, and the impression created on the minds of contemporaries by the influence which he asserted in central Wales is enshrined in contemporary prose romances. ^[1]

Division of Dominions at Death

It is sometimes said that Powys Fadog was named after him. This is incorrect. Powys Fadog was named after Madog ap Gruffudd Maelor.^[5][13]

His dominions were divided among his sons and nephews: Gruffydd Maelor I, Owain Fychan, Owain Brogyntyn, and Owain Cyfeiliog.^[1]

After his death, his dominions were divided among a number of minor lords of Powys — his sons and nephews — and were never again to be reunited in the hands of a single ruler. ^[1]

The Mabinogion

The Mabinogion tale The Dream of Rhonabwy is set during Madog's reign. The central character, Rhonabwy, is one of Madog's retainers sent to bring in Madog's rebellious brother Iorwerth. His titular dream contrasts his own time with the grandeur of King Arthur's period.^[14]

Issue

Boyer, following Bartrum, shows Gruffudd and Elise as children of Madog and his wife Susann. Boyer shows no children attributed to Gruffudd's second wife Arianwen. He shows Einion and Cynwrig as children of mistress Efa ferch Einion, and the rest of the children as mother unknown. ^[2]

Cawley shows four children, LLewelyn, Gruffudd, Marared, and Gwenllian as children of Gruffudd and "his wife", but is not aware of a second wife. He shows the remaining children as children of various mistresses. ^[7]

The Dictionary of Welsh Biography shows seven children of Madog ap Maredudd, without indicating a mother for them: Gwenlian, Margaret, Gruffydd, Owain Fychan, Owain Brogyntyn, Cynric Efell, and Llywelyn.

1. Gruffudd Maelor. Son of Gruffudd and his first wife Susanna. died 1191. Married Angharad ferch owain Gwynedd. ^[2] Gruffudd "Maelor" I (-1191, bur Meivod).

Wolcott shows descent from Madog (born, say, 1098, obit 1160) to his son

1. Gruffudd Maelor I ap Madog (obit 1191)
   
   1. 1160 Madog ap Gruffydd Maelor (obit 1236)
      
      1. 1195 Gruffudd Maelor II (obit 1269)

Succession Shared

Madog's eldest son, Llywelyn, was killed soon after his father's death and Powys was shared between a number of sons and nephews. Powys was never subsequently reunited, being separated into two parts Powys Fadog and Powys Wenwynwyn. Madog's death enabled Owain Gwynedd to annex part of northern Powys. The poet Cynddelw Brydydd Mawr in his elegy on Madog said:

While Madog lived there was no man

Dared ravage his fair borders

Yet nought of all he held

Esteemed he his save by God's might ...

If my noble lord were alive

Gwynedd would not now be encamped in the heart of Edeyrnion ^[14]
