Richard II

The play spans only the last two years of Richard's life, from 1398 to 1400. It begins with King Richard sitting majestically on his throne in full state, having been requested to arbitrate a dispute between the nobles Thomas Mowbray and Richard's cousin, Henry Bolingbroke, who has accused Mowbray of high treason for stealing money that had been raised for the English army and of murdering Bolingbroke's uncle, the Duke of Gloucester. Bolingbroke's father, John of Gaunt, 1st Duke of Lancaster, meanwhile, believes Richard himself was responsible for his brother's murder. After several attempts to calm both men, Richard acquiesces and it is determined that the matter be resolved in the established method of trial by battle between Bolingbroke and Mowbray, despite Gaunt's objections.
The tournament scene is very formal, with a long, ceremonial introduction, but as the combatants are about to fight, Richard interrupts and sentences both men to banishment from England. Bolingbroke is originally sentenced to ten years' banishment, but Richard reduces this to six years upon seeing John of Gaunt's grieving face. Mowbray is banished permanently. The king's decision can be seen as the first mistake in a series leading eventually to his overthrow and death, since the error highlights many of his character flaws, including indecisiveness (in terms of whether to allow the duel to go ahead), abruptness (Richard waits until the last possible moment to cancel the duel), and arbitrariness (there is no apparent reason Bolingbroke should be allowed to return and Mowbray not). In addition, the decision fails to dispel the suspicions surrounding Richard's involvement in the death of the Duke of Gloucester—in fact, by handling the situation in such a cavalier and arbitrary manner, Richard only appears more guilty. Mowbray correctly predicts that the king will sooner or later fall at the hands of Bolingbroke.

After an impassioned invective against the visiting king from his sick-bed, John of Gaunt dies and Richard seizes all his land and money. This angers the nobility, who accuse Richard of wasting England's money, of illegally depriving John's heir Bolingbroke of his rightful inheritance to fund war in Ireland, of imposing unjust taxes on the commoners, and of enriching himself by fining the nobles for crimes their ancestors committed. The conspirators help Bolingbroke return secretly to England, with a plan to overthrow Richard. There remain, however, subjects loyal to the king. Among them are the courtiers Bushy, Bagot, and Green, as well as the Duke of Aumerle (son of the Duke of York), cousin of both Richard and Bolingbroke. When Richard leaves England to attend to the war in Ireland, Bolingbroke seizes the opportunity to assemble an army and invades the north coast of England. Executing both Bushy and Green, Bolingbroke wins over the Duke of York, whom Richard has left in charge of his government in his absence.
Upon Richard's return, Bolingbroke reclaims his lands and lays claim to the English throne; Richard's Welsh allies desert him and he is taken captive. After a dramatic public ceremony where Bolingbroke has the captive king publicly renounce his crown, he crowns himself King Henry IV, and has Richard imprisoned in the castle of Pomfret. Aumerle orchestrates an uprising against the new king, only to be thwarted by his father, York. The King executes every conspirator except Aumerle, who is spared after the Duchess of York intervenes on his behalf. The ambitious Sir Piers Exton takes King Henry's words "Have I no friend will rid me of this living fear?" as a request to kill the still-living Richard. Exton murders Richard in his cell to gain Henry's favour. While admitting that he "did wish [Richard] dead", King Henry is appalled by the murder, dismisses Exton from his court, and vows a pilgrimage to Jerusalem to cleanse himself of his part in Richard's death. In his final lines, Henry completes the tragic structure of the play by mourning over Richard's coffin.
