He is described by Bishop Stubbs as \"a feudal adventurer of the worst type,\" and for some time was actively engaged in the struggles of the Norman barons against both John and Henry III.\\nHe was one of the twenty-five executors of the Great Charter; but in the war that followed sided with John, subsequently changing sides as often as it suited his policy. His object was to revive the independent power of the feudal barons, and he co-operated to this end with Falkes de Breaut and other foreign adventurers established in the country by John. This brought him into conflict with the great justiciar, Hubert de Burgh, and in 1219 he was declared a rebel and excommunicated for attending a forbidden tournament. In 1220 matters were brought to a crisis by his refusal to surrender the two royal castles of Rockingham and Sauvey of which he had been made constable in 1216. Henry III marched against them in person, the garrisons fled, and they fell without a blow. In the following year, however, Albemarle, in face of further efforts to reduce his power, rose in revolt.\\nHe was now again excommunicated by the legate Pandulph at a solemn council held in St Paul\\'s, and the whole force of the kingdom was set in motion against him, a special scutage—the scutagium de Bihan—being voted for this purpose by the Great Council. The capture of his Castle of Bytham broke his power; he sought sanctuary and, at Pandulph\\'s intercession, was pardoned on condition of going for six years to the Holy Land. He remained in England, however, and in 1223 was once more in revolt with Falkes de Breaute, the Earl of Chester and other turbulent spirits. A reconciliation was once more patched up; but it was not until the fall of Falkes de Breaute that Albemarle finally settled down as an English noble.\\nIn 1225 he witnessed Henry\\'s third re-issue of the Great Charter; in 1227 he went as, ambassador, to Antwerp; and in 1230 he accompanied Henry on his expedition to Brittany. In 1241 he set out for the Holy Land, but died at sea, on his way there, on March 26 1242.\" wikipedia', 'type': 'Person', 'id': 'W_earl_Aubermarle'}, {'label': 'Mortimer, Roger (d.1214)', 'type': 'Person', 'id': 'Mortimer_Roger_d_1214'}, {'label': 'Richard Corbet', 'type': 'Person', 'id': 'Richard_Corbet'}, {'type': 'Person', 'label': 'Ranulf de Aldithele', 'id': 'Ranulf_de_Aldithele'}, {'type': 'Person', 'label': 'Roger Picard', 'id': 'Roger_Picard'}, {'label': 'Ferrières, Walcheline de (d 1201)', 'type': 'Person', 'id': 'Ferrières_Walcheline_de_d_1201'}, {'type': 'Person', 'label': 'Beauchamp, Walter de', 'id': 'Beauchamp_Walter_de'}, {'label': 'John de Lodbroc', 'type': 'Person', 'id': 'John_de_Lodbroc'}, {'label': 'Corbet, Reginald', 'type': 'Person', 'id': 'Corbet_Reginald'}, {'label': 'William de Gamages', 'type': 'Person', 'id': 'William_de_Gamages'}, {'type': 'Person', 'label': 'Llywelyn ab Iorwerth', 'id': 'Llywelyn_ab_Iorwerth'}, {'type': 'Person', 'label': 'Walter de Lacy, d1241', 'id': 'Lacy_Walter_de_d_1241'}, {'type': 'Person', 'label': 'Henry de Gamages', 'id': 'Henry_de_Gamages'}, {'label': 'William Sampson', 'type': 'Person', 'id': 'Sampson_William'}, {'type': 'Person', 'label': 'Ralph fitz Nicholas', 'id': 'Ralph_fitz_Nicholas'}, {'name': 'William de Stutevill', 'type': 'Person', 'label': 'Stutevill de, William', 'id': 'William_de_Stutevill'}, {'type': 'Person', 'label': 'Peter fitz Herbert', 'id': 'Peter_fitz_Herbert'}, {'type': 'Person', 'label': 'John de Stafford', 'id': 'John_de_Stafford'}, {'label': 'Phillippa Basset (d 1265)', 'type': 'Person', 'id': 'Phillippa_Basset_d_1265'}, {'comment': ' March connection: \"Thomas de Newburgh, son of Henry Earl of Warwick, the conqueror of Gower, parted with the lordship to the crown.
