Reginald de Braose (died June 1228) was one of the sons of William de Braose, 4th 
Lord of Bramber and Matilda, also known as Maud de St. Valery and Lady de la Haie. 
Her other children included William and Giles.[1]

The de Braoses were loyal to King Richard I but grew in power under King John of 
England. The dynasty was in conflict with King John towards the end of his reign and 
almost lost everything.

Reginald de Braose was a scion of the powerful Marcher family of de Braose, helped 
manage its survival and was also related by marriage to the Welsh Princes of Wales.
Magna Carta[edit]

He supported his brother Giles de Braose in his rebellions against King John. Both 
brothers were active against the King in the Baron's War. Neither was present at the 
signing of Magna Carta in June 1215 because at this time they were still rebels who 
refused to compromise.

Restoration of royal favour[edit]

King John acquiesced to Reginald's claims to the de Braose estates in Wales in May 
1216. Reginald became Lord of Brecon, Abergavenny, Builth and held other Marcher 
Lordships but was also very much a vassal of the Welsh leader Llewelyn Fawr, Prince 
of Gwynedd who had become his father-in-law in 1215 [2] when Reginald married 
Llywelyn's daughter, Gwladus Ddu.

Henry III restored Reginald to favour and the Bramber estates (confiscated by King 
John) in 1217.

Welsh wars[edit]

At this seeming betrayal, Rhys and Owain, Reginald's Welsh nephews who were 
Princes of Deheubarth, were incensed and took Builth, except the castle. Llywelyn 
Fawr also became angry and his forces besieged Brecon. Reginald eventually 
surrendered to Llewelyn and gave up Seinhenydd (Swansea).

By 1221 they were at war again, with Llewelyn again laying siege to Builth. The siege 
was relieved by King Henry III's forces. From this time on Llewelyn tended to support 
the claims of Reginald's nephew John de Braose concerning the de Braose lands in 
Wales.

Reginald was a witness to the re-issue of Magna Carta by King Henry III in 1225.

He died two or three years later in 1227 or 1228 in Brecon and was succeeded by his 
son by his first wife, Graecia Briwere (or Brewer), daughter of William Brewer, 1st 
Baron Brewer, the ill-fated William de Braose. He was buried in Brecon Priory Church 
(now Brecon Cathedral).

It may be that the Matilda de Braose who was the wife of Rhys Mechyll, Prince of 
Deheubarth was the daughter of Reginald.
