Richard II by William Shakespeare The Life and Death of King Richard the Second, commonly called Richard II, is a history play by William Shakespeare believed to have been written around 1595.

It is based on the life of King Richard II of England (ruled 1377–1399) and chronicles his downfall and the machinations of his nobles. It is the first part of a tetralogy, referred to by some scholars as the Henriad, followed by three plays about Richard's successors: Henry IV, Part 1; Henry IV, Part 2; and Henry V.

Although the First Folio (1623) includes the play among the histories, the earlier Quarto edition of 1597 calls it The tragedie of King Richard the second.

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 Thomas Mowbray and Richard's cousin, Henry Bolingbroke, later Henry IV, who has accused Mowbray of squandering money given to him by Richard for the king's soldiers and of murdering Bolingbroke's uncle, the Duke of Gloucester.

Bolingbroke's father, John of Gaunt, 1st Duke of Lancaster, meanwhile, believes it was Richard himself who 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 the objections of Gaunt.
