John Montagu, 3rd Earl of Salisbury

Bolingbroke was to entrust his young son and heir, later Henry V, to the care of the Montagu family, following the death of his wife Mary de Bohun.

After his mother's death, the earl's wife, Maud, cared for the young boy at Courtfield, the Montagus' manor house in Welsh Bicknor, near Monmouth.

He continued as one of the major aristocratic allies of King Richard II, helping to secure the fall of the Duke of Gloucester and the Earl of Warwick.

Early in 1399, he went to France on a successful mission to prevent the proposed marriage of Henry Bolingbroke and a daughter of the Duke of Berry.

Not long after his release, Montagu joined with the Earl of Huntingdon and a group of other barons in the Epiphany Rising, a plot to kill King Henry IV and restore Richard II.
