Henry Bolingbroke-now King Henry IV-is having an unquiet reign. His personal disquiet at the usurpation of his predecessor Richard II would be solved by a crusade to the Holy Land, but broils on his borders with Scotland and Wales prevent that. Moreover, he is increasingly at odds with the Percy family, who helped him to his throne, and Edmund Mortimer, the Earl of March, Richard II's chosen heir. Adding to King Henry's troubles is the behaviour of his son and heir, the Prince of Wales. Hal (the future Henry V) has forsaken the Royal Court to waste his time in taverns with low companions. This makes him an object of scorn to the nobles and calls into question his royal worthiness. Hal's chief friend and foil in living the low life is Sir John Falstaff. Fat, old, drunk, and corrupt as he is, he has a charisma and a zest for life that captivates the Prince. The play features three groups of characters that interact slightly at first, and then come together in the Battle of Shrewsbury, where the success of the rebellion will be decided. First there is King Henry himself and his immediate council. He is the engine of the play, but usually in the background. Next there is the group of rebels, energetically embodied in Henry Percy ("Hotspur") and including his father, the Earl of Northumberland and led by his uncle Thomas Percy, Earl of Worcester. The Scottish Earl of Douglas, Edmund Mortimer and the Welshman Owen Glendower also join. Finally, at the centre of the play are the young Prince Hal and his companions Falstaff, Poins, Bardolph, and Peto. Streetwise and pound-foolish, these rogues manage to paint over this grim history in the colours of comedy.
