Roger de Montgomerie, 1st Earl of Shrewsbury

Roger de Montgomerie (died 1094), also known as Roger the Great de Montgomery, was the first Earl of Shrewsbury, and Earl of Arundel, Sussex. His father was Roger de Montgomery, seigneur of Montgomery, and was a relative, probably a grandnephew, of the Duchess Gunnor, wife of Duke Richard I of Normandy. The elder Roger had large holdings in central Normandy, chiefly in the valley of the Dives, which the younger Roger inherited.

Roger was one of William the Conqueror's principal counsellors, playing a major role in the Council of Lillebonne. He may not have fought in the initial invasion of England in 1066, instead staying behind to help govern Normandy. According to Wace’s Roman de Rou, however, he commanded the Norman right flank at Hastings, returning to Normandy with King William in 1067. Afterwards he was entrusted with land in two places critical for the defence of England, receiving the Rape of Arundel at the end of 1067 (or in early 1068), and in November 1071 he was created Earl of Shrewsbury; a few historians believe that while he received the Shropshire territories in 1071 he was not created Earl until a few years later.

Roger was thus one of the half dozen greatest magnates in England during William the Conqueror's reign. William gave Earl Roger nearly all of what is now the county of West Sussex, which at the time of the Domesday Survey was the Rape of Arundel. The Rape of Arundel was eventually split into two rapes, one continuing with the name Rape of Arundel and the other became the Rape of Chichester. Besides the 83 manors in Sussex, his possessions also included seven-eighths of Shropshire which was associated with the earldom of Shrewsbury, he had estates in Surrey (4 manors), Hampshire (9 manors), Wiltshire (3 manors), Middlesex (8 manors), Gloucestershire (1 manor), Worcestershire (2 manors), Cambridgeshire (8 manors), Warwickshire (11 manors) and Staffordshire (30 manors). The income from Roger’s estates would amount to about £2000 per year, in 1086 the landed wealth for England was around £72,000, so it would have represented almost 3% of the nation’s GDP.
