[Kneeling] By earth, the common mother of us all,
By heaven, and all the moving orbs thereof,
By this right hand, and by my father's sword,
And all the honours 'longing to my crown,
I will have heads and lives for him as many
As I have manors, castles, towns and towers!

From that oath is born the catastrophe that immediately ensues. A temporary victory, followed up by revengeful executions, is succeeded by defeat, captivity, loss of the crown, and a fearful death.

King Edward is not portrayed as weak mentally or morally. Gaveston, in the first scene, speaks of his master's effeminacy, and on more than one occasion there are hints from the royal favourites that the king should assert his majesty more vigorously. But over and over again Edward breaks out into anger at the insolence of his subjects and only fails to crush them through the impossibility of exacting obedience from those about him. In Act I, Scene 4, it is Mortimer's order for the seizure of Gaveston that is obeyed, not the king's command for Mortimer's arrest. When the warrant for his minion's exile is submitted to him, the king refuses point blank, in the face of threatening insistence. 'I will not yield', he cries; 'curse me, depose me, do the worst you can.' He only gives way at last before a threat of papal excommunication, the crushing power of which had been made abundantly clear by its effect on King John just a century before. Indeed we need not go further than the first scene to find that Marlowe is resolved to put the right spirit of wilfulness and angry determination in his fated monarch. There we find this speech by him:

Well, Mortimer, I'll make thee rue these words;
Beseems it thee to contradict thy king?
Frownest thou thereat, aspiring Lancaster?
This sword shall plane the furrows of thy brows,
And hew these knees that now are grown so stiff.
I will have Gaveston; and you shall know
What danger 'tis to stand against your king.

And again, when the barons have withdrawn, he bursts out—

I cannot brook these haughty menaces;
Am I a king, and must be over-ruled!—
Brother, display my ensigns in the field:
I'll bandy with the barons and the earls,
And either die or live with Gaveston.

Nor is this pride of sovereignty lost even in defeat. We see it still as strong, though forced by circumstances and coaxed to give way, in the pathetic scene where he is compelled to surrender his crown to Mortimer's delegate. Nevertheless the weakness that brings and justifies his downfall is placed prominently before us from the first. King Edward prefers his own pleasure before the unity of his kingdom and the strength of his rule. There is even something a little ignoble in his love for Gaveston, something unmanly and contemptible, if the reports of such prejudiced persons as the queen and Mortimer are to be believed. But the fault is not a criminal or unnatural one. One can sympathize with a heart that yearns for the presence of a single friend in a world of cold-blooded critics or harsh counsellors. The not unattractive character of Gaveston, too, affectionate, gay, proud, quick-tempered, brave—with faults also, of deceit, vanity and vindictiveness—preserves the royal friendship from the sink of blind dotage upon an unworthy creature. The tragedy follows, then, from the king's preferment of private above public good, or, we may say, from the conflict between the king's wishes as a man and his duty as a monarch. It is to Marlowe's perception of this vital struggle underlying the hostility between King Edward and his nobles that the play owes its greatness. We pity the king, we can hate those who beat him down to the mire, because his fault appeals to us in its personal aspect as almost a virtue; he is willing to sacrifice so much to keep his friends. At the same time we perceive the justice of his dethronement, for we recognize that the duty of a king must take precedence over everything else. He has brought his punishment upon himself. Yet, inasmuch as Mortimer, serviceable to the state as an instrument, offends our sense of what is due from a subject to his sovereign, we applaud the justice of his downfall; we, perhaps, secretly rejoice that this bullying young baron is humbled beneath a king's displeasure at last. As a final touch Marlowe rescues the sovereignty of the throne from the taint of weakness by the little prince's vigorous assertion of his authority at the end.

Queen Isabella presents certain difficulties. The king's treatment of her reflects little credit upon him, although one can hardly demand the same affection in a political as in a voluntary union. Apparently she really loves the king until his continued coldness chills her feelings and drives them to seek return in the more responsive heart of Mortimer. After that she even sinks so low as to wish the king dead. Yet to the end she cherishes a warm love for her son. Probably the author intended that her degeneracy should be attributed to the baneful influence of Mortimer and so strengthen the need for his death.

Mortimer, as the great antagonist, has a very strong character. Imperious, fiery, he is the real leader of the barons. From the first it is apparent that he is actuated by personal malice as much as by righteous indignation on behalf of his misgoverned country. He confides to his uncle that it is Gaveston's and the king's mocking jests at the plainness of his train and attire which make him impatient. But the unwisdom of the king serves him for a stalking-horse while secretly he pursues the goal of his private ambition. In adversity he is uncrushed. When he returns victorious he ruthlessly sweeps aside all likely obstacles to his supremacy, the Spensers, Kent, and even the king being hurried to their death. Then, just as he thinks to stand at the summit, he falls—and falls grandly.

Base Fortune, now I see that in thy wheel
There is a point, to which when men aspire,
They tumble headlong down: that point I touched;
And seeing there was no place to mount up higher,
Why should I grieve at my declining fall?—
Farewell, fair queen: weep not for Mortimer,
That scorns the world, and, as a traveller,
Goes to discover countries yet unknown.
