Robert de Beaumont, 3rd Earl of Leicester

Robert de Beaumont, 3rd Earl of Leicester (died 1190) was an English nobleman, one of the principal followers of Henry the Young King in the Revolt of 1173–1174 against his father Henry II. He is also called Robert Blanchemains (meaning "White Hands" in French).

He was the son of Robert de Beaumont, 2nd Earl of Leicester, a staunch supporter of Henry II, and he inherited from his father large estates in England and Normandy.

When the revolt of the younger Henry broke out in April 1173, Robert went to his castle at Breteuil in Normandy. The rebels' aim was to take control of the duchy, but Henry II himself led an army to besiege the castle; Robert fled, and the Breteuil was taken on September 25 or 26.

Robert apparently went to Flanders, where he raised a large force of mercenaries, and landed at Walton, Suffolk, on 29 September 1173. He joined forces with Hugh Bigod, 1st Earl of Norfolk, and the two marched west, aiming to cut England in two across the Midlands and to relieve the king's siege of Robert's castle at Leicester. However, they were intercepted by the king's supporters and defeated at the Battle of Fornham near Fornham, near Bury St Edmunds, on 17 October. Robert, along with his wife and many others, was taken prisoner. Henry II took away the earl's lands and titles as well.

He remained in captivity until January 1177, well after most of the other prisoners had been released. The king was in a strong position and could afford to be merciful; not long after his release Robert's lands and titles were restored, but not his castles. All but two of his castles had been destroyed, and those two (Montsorrel in Leicestershire and Pacy in Normandy) remained in the king's hands.
