The Earl of Northumberland is an English nobleman with little love for Richard. When the King leaves for Ireland, Northumberland draws most of the rest of the nobility into a conspiracy against him to help Bullingbrook return.
He quickly becomes Bullingbrook’s second-in-command and hatchet-man, and is the first to begin to regard Richard as deposed. He is a prosaic man, though he manages to entice Richard to leave the security of Flint Castle, and insists that Richard’s deposing be carried through to the letter as the Commons insist, including forcing Richard to agree that he has done wrong and is therefore justly overthrown. He is quite unsentimental, quick to cease speaking respectfully to the deposed King and to force him and his Queen to part, not to mention arrest the Bishop of Carlisle. He is generally in charge of executions for Henry IV. His further adventures can be found in Henry IV Part One.
