Roger de Clare, 2nd Earl of Hertford, 5th Lord of Clare, 5th Lord of Tonbridge, 5th Lord of Cardigan (1116–1173) was a powerful Anglo-Norman noble in 12th-century England. He succeeded to the Earldom of Hertford and Honor of Clare, Tonbridge and Cardigan when his brother Gilbert died without issue. Life Roger was a son of Richard Fitz Gilbert de Clare and Alice de Gernon. In 1153, he appears with his cousin, Richard Strongbow, Earl of Pembroke, as one of the signatories to the Treaty of Wallingford, in which Stephen recognises Henry of Anjou as his successor. Roger is found signing charters at Canterbury and Dover in 1156. Next year, according to Powell, he received from Henry II a grant of whatever lands he could conquer in South Wales. This is probably only an expansion of the statement of the Welsh chronicles that in this year (about 1 June) he entered Cardigan and 'stored' the castles of Humfrey, Aberdyfi, Dineir, and Rhystud. Rhys ap Gruffydd, the prince of South Wales, appears to have complained to Henry II of these encroachments ; but being unable to obtain redress from the king of England sent his nephew Einion ab Anarawd to attack Humfrey and the other Norman fortresses. The 'Annales Cambriæ seem to assign these events to the year 1159 ; and the 'Brut' adds that Prince Rhys burnt all the French castles in Cardigan. In 1158 or 1160, Roger advanced with an army to the relief of Carmarthen Castle, then besieged by Rhys, and pitched his camp at Dinweilir. Not daring to attack the Welsh prince, the English army offered peace and retired home. In 1163, Rhys again invaded the conquests of Clare, who,learn incidentally, has at some earlier period caused Einion, the capturer of Humfrey Castle, to be murdered by domestic treachery. In 1164 he assisted with the Constitutions of Clarendon. From his munificence to the Church and his numerous acts of piety, Roger was called the "Good Earl of Hertford". He was the founder of Little Marcis Nunnery prior to 1163. A second time all Cardigan was wrested from the Norman hands; and things now wore so threatening an aspect that Henry II led an army into Wales in 1165, although, according to one Welsh account, Rhys had made his peace with the king in 1164, and had even visited him in England.
