Henriad is a common title used by scholars for Shakespeare's second historical tetralogy, comprising Richard II; Henry IV, Part 1; Henry IV, Part 2; and Henry V. The plays depict the destabilising effects of the violation of political continuity with the overthrow of Richard II of England followed by the growth of Henry V of England from a wild youth to a great war leader in Henry V. Although it was the second tetralogy to be written and performed, the subject matter comes chronologically before the first tetralogy comprising the three Henry VI plays and Richard III. The term "Henriad" derives from the Classical epics the Iliad and Aeneid.
