Reginald supported Giles in his rebellions against King John. They were bo
th active against the King in the barons' war. Neither was present at t
he signing of Magna Carta because they were still rebels who refused to co
mpromise. K. John aquiesced to Reginald's claims to the De Braose estat
es in Wales in May 1216. He became Lord of Brecon, Abergavenny, Builth a
nd other Marcher Lordships but was very much a vassal of Llewelyn Fawr, Pr
ince of Gwynedd and now his father-in-law. Henry III restored Regina
ld to favour and the Bramber estates (confiscated from William by K. Joh
n) in 1217. At this seeming betrayal, Rhys and Owain, Reginald's nephews w
ho were princes of Deheubarth, were incensed and they took Builth (exce
pt the castle). Llewelyn Fawr also became angry and besieged Brecon. Regin
ald eventually surrendered to Llewelyn and gave up Seinhenydd (Swansea
). By 1221 they were at war again with Llewelyn laying siege to Builth. T
he seige was relieved by Henry III's forces. From this time on Llewelyn te
nded to support the claims of Reginald's nephew John concerning the De Bra
ose lands.
Reginald was a witness to the re-issue of Magna Carta by Henry III in 1225
