Robert Of Mortain

Robert was the half-brother of William the Conqueror (c. 1028-1087) and landowner with estates in Normandy and throughout England.

He was created Count of Mortain in south-west Normandy around 1055. In William’s conquest of England in 1066 and its subsequent pacification until 1069, he proved himself to be an effective military leader. For his role in William’s wars Robert was rewarded with 800 manors all over Britain from Sussex to Yorkshire in the north and out to Cornwall in the west. On the Bayeux Tapestry he is depicted left of William.

Robert’s total wealth was estimated around £8,000, or over 5.3% of net national income. In 2010 that would correspond to £59.1bn.
