The drama focuses on Henry IV's difficult relationship with his son Prince Hal, and the latter's gradual emergence as a charismatic sovereign. In the process he sheds his image as a prodigal wastrel dramatised in the first half of Part One, assuming the title of King Henry V in the closing scenes of Part Two. Perhaps the most poignant moment of the whole play remains Henry's cold-blooded rejection of Falstaff, his surrogate father for much of Part One. "I know thee not, old man" he tells the crushed Falstaff as he assumes the royal crown, preparing the audience for the type of monarch they will see in Shakeseare's subsequent dramatisation of English history, Henry V. --Jerry Brotton
