Shakespearian Henriad refers to a group of four William Shakespeare's history plays: Richard II, Henry IV, Part 1, Henry IV, Part 2, and Henry V. These four plays constitute the Shakespearian epic with Prince Harry, who later becomes Henry V, as a central figure. Thanks to Shakespeare, King Henry V today stands side by side with the classical epic heroes such are Achilles and Aeneas, as one of the greatest warrior kings of medieval England,.
