Throughout Henry IV, Part 2, the rebel leaders have been plotting their next move: In a narrative sense, the play has therefore been building toward a confrontation similar to the Battle of Shrewsbury in Henry IV, Part 1, in which the dramatic defeat of Hotspur was the climax of the play’s action and thus set the scene for the sequel. In Part 2, however, no such battle takes place. Instead, the rebel lords agree to meet with a representative of the king. Prince John is not even the king’s firstborn son, nor is he the heir to the throne, hinting at the contempt in which the rebel lords are held. Whereas the king once sent his heir into battle to defeat a legitimate foe, he now sends his second-born son to treat with whatever remnants of the rebellion remain. Symbolically, the king is asserting his authority and humbling his challengers, but the narrative effect is to reinforce a sense of diminished scale and prestige.

Moreover, this meeting culminates in a betrayal that underscores the sense of decline. The morality of Prince John’s actions is somewhat ambiguous. To the rebel lords, he has acted in a dishonorable fashion and defeated them through deceit. From the perspective of the king and his supporters, however, the rebel leaders have abandoned any claim to the moral high ground by rebelling against the king. They have rejected the moral expectations of the social order through their rebellion, Prince John implies, and thus cannot expect to be treated honorably. The characterization of the rebels throughout the play nudges the audience toward this interpretation, as Shakespeare shows them moving forward with the rebellion largely because they feel it is their only hope of avoiding charges of treason. That they rebel out of self-preservation and self-interest rather than any patriotic cause frames their ultimate fate as both ironic and deserved. 

Still, Prince John proves far more willing to undermine expectations of honor and civility than any other character in the play, and his actions become an interrogation of the moral rights of the monarchy and whether the state is required to treat even rebels in an honorable manner. According to the victorious side, the answer is no, but the scene contributes to the atmosphere of moral decay, not least because it recalls Falstaff’s trickery. This complicates the theme of Shaping identity Through Moral Choice in its suggestion that what makes an action “right” or “wrong” is the power that underpins it. In other words, it implies that a figure like Falstaff is morally suspect not because of what he does; rather, his actions are morally suspect because of who he is, inverting the relationship between ethics and identity.

Act IV juxtaposes the resolution of the rebellion with the climax of the more personal conflict between the king and his heir, implying parallels between the two; Prince Hal’s behavior becomes a form of rebellion against the man to whom he owes allegiance as both a sovereign and father. The irony of King Henry’s despondency as Scene 3 begins serves as tacit commentary on which form of civil unrest—the rebellion or the prince’s behavior—is more dangerous to both the king’s well-being and the security of the realm. The messages of summons, of news, or of tragedy have been poorly received throughout the play, and the play itself opened with a warning against the false reports that are often spread by rumors. King Henry’s victory is so complete, however, that he need not worry about such matters: His enemies are defeated, apparently without significant bloodshed. King Henry IV is thus at the pinnacle of his power, yet he is unable to derive any pleasure from the news. Not only is his health failing, but he is beset by fear that his legacy will not be his military victories but the waywardness of his son and heir. This fear is made worse when he notices the crown missing from his pillow, an act that he describes as “nature fall[ing] into revolt” in that it apparently merges the prince’s personal betrayal of his father with the political act of usurpation (IV.3.196). 

The emotional reconciliation between father and son that follows largely dispels this idea. The prince’s confession both acknowledges his poor judgment in the past and declares his love for his father, signaling to the king that his fears were misplaced: His son is already showing the levels of introspection and self-awareness that characterize King Henry’s speeches throughout the play. Now, his victories take on a different meaning: Rather than clearing the agenda for his own ambitions, his victories are his gift to his son, offering the soon-to-be King Henry V a blank slate on which to establish his own legacy. The dying king sees his own rule in a new context, recognizing himself as a transitional figure whose vision will be better realized by his son. Prince Henry’s stark confession of his sins and his acceptance of his true self are thus mirrored in King Henry’s realization of his place in history as the head of a newly founded dynasty. Finally at peace, he accepts his death with grace, resolving the play’s exploration of Confronting Aging and Mortality.

Nevertheless, a hint of ambiguity lingers regarding Hal’s actions. His framing of the crown as his father’s enemy corresponds to the soliloquy that he delivers when he believes that King Henry is dead, but his request that God prevent him from being king if he proved unworthy is at odds with his earlier commitment to retaining the crown: 

Lo where it sits— 

Which God shall guard; and put the world’s whole strength 

Into one giant arm, it shall not force 

This lineal honour from me (IV.3.174-77). 

This suggests a measure of truth to the king’s initial accusation that the prince believed him to be dead because doing so suited his own desires (a claim that also recalls the Induction’s warnings).
