But there remains the fifth condition: whatever his defects, Richard II is the legitimate King of England. Since all men are mortal, and many men are ambitious, unless there is some impersonal principle by which, when the present ruler dies, the choice of his successor can be decided, there will be a risk of civil war in every generation. It is better to endure the injustice of the legitimate ruler, who will die anyway sooner or later, than allow a usurper to take his place by force.
As a potential ruler, Bolingbroke possesses many of the right qualities. He is a strong man, he knows how to make himself popular, and he would like to be just. We never hear, even from the rebels, of any specific actions of Henry IV which are unjust, only of suspicions which may be just or unjust. But in yielding to the temptation, when the opportunity unexpectedly offers itself, of deposing his lawful sovereign, he commits an act of injustice for which he and his kingdom have to pay a heavy price. Because of it, though he is strong enough to crush rebellion, he is not strong or popular enough to prevent rebellion breaking out.
Once Richard has been murdered, however, the rule of Henry IV is better than any alternative. Though, legally, Mortimer may have a good or better right to the throne, the scene at Bangor between Hotspur, Worcester, Mortimer, and Glendower, convinces us that Henry's victory is a victory for justice since we learn that the rebels have no concern for the interests of the Kingdom, only for their own. Their plan, if they succeed, is to carve up England into three petty states. Henry may wish that Hotspur, not Hal, were his heir, because Hotspur is a brave warrior ready to risk his life in batde against England's foes, while Hal appears to be dissipated and frivolous, but we know better. Hotspur is indeed brave, but that is all. A man who can say
I'll give thrice so much land To any well-deserving friend; But in the way of bargain, mark ye me, I'll cavil on the ninth part of a hair
is clearly unfitted to be a ruler because his actions are based, not on justice, but on personal whim. Moreover, he is not interested in political power; all he desires is military glory.
Thirdly, there is Prince Hal, Henry V-to-be. To everyone except himself, he seems at first to be another Richard, unjust, lacking in self-control but, unfortunately, the legitimate heir. By the time the curtain falls on
One of FalstafFs dramatic functions is to be the means by which Hal is revealed to be the Just Ruler, not the dissolute and frivolous young man everybody has thought him; but, so far as the audience is concerned, Falstaff has fulfilled his function by Act III, Scene
I'll so offend to make offense a skill,
Redeeming time when men least think I will.
But then we watch the rebellion being prepared while he does nothing but amuse himself with Falstaff, so that we are left wondering whether he meant what he said or was only play acting. But from the moment he engages in the political action of the play, we have no doubts whatsoever as to his ambition, capacity, and ultimate triumph for, however often henceforward we may see him with Falstaff, it is never at a time when his advice and arms are needed by the State; he visits the Boar's Head in leisure hours when there is nothing serious for him to do.
