Macbett and Lady Duncan's Power Alliance

Macbett and Lady Duncan's Power Alliance begins as a performance of love and national service, then reveals itself as a bargain joining desire to the pursuit of sovereignty. Disguised among the witches, Lady Duncan offers Macbett the means and encouragement to act against Duncan; he answers first with scruples, then with submission. The alliance's force lies in that conversion: ambition is not merely promised a reward, but recast as a shared project for the country's supposed benefit.

A Political Partnership in Disguise

At first, Macbett addresses the First Witch as one of the old women and tests whether she truly has his interests at heart. Her answer is intimate—she says they love him—while the Second Witch enlarges the claim, linking that love to the country, justice, and the commonwealth. The First Witch adds a public justification: the plan is presented as aid to the poor and a means of bringing peace to a suffering country. These declarations give the proposed partnership the language of service rather than private advancement.

The scene then makes the disguise literal. As the First Witch receives a scepter and crown, she appears haloed in the stage lighting; the Second Witch removes her mask and old clothes. The First Witch is revealed as Lady Duncan, and the Second becomes her young lady in waiting. The revelation changes the meaning of the witches' appeals: Macbett has not been courted by an impersonal supernatural force alone, but by Duncan's wife, whose claim to love and political purpose now has a visible human identity. Macbett recognizes the voice and, once she is revealed, falls to his knees.

Ambition Offered as an Intimate Bargain

Lady Duncan makes the terms of the alliance explicit by holding out a dagger and telling Macbett, “Here is the instrument of your ambition and our rise to power.” She offers herself alongside political advancement: he may take the weapon if he wants her, and he is to take Duncan's place at her side, becoming her sovereign while she becomes his mistress. The promised relationship is therefore also a division of power. Desire supplies the personal inducement; the crown and the proposed change of ruler supply its political stakes.

Macbett does not accept at once. He says that he has scruples and asks whether they cannot simply do otherwise, leaving open his reluctance to take the decisive step himself. Lady Duncan counters by distinguishing his courage in carrying out orders from the guilt that may stop him when the action is his own. She reminds him that he has killed when another person gave the command, then offers to reassure him with the witches' assurances: no man born of a woman will conquer him, and no army will defeat his army until the forest arms itself to march against him. The alliance thus answers a specific hesitation with both personal persuasion and predictions of political security.

Submission and the Promise of Rule

The lady in waiting supports Lady Duncan's appeal by describing the projected partnership as a way to save the country and build a better society. That public promise sits beside the scene's overtly personal seduction: Lady Duncan holds out the dagger, urges Macbett to act boldly, and makes his desire part of her argument. The contrast does not resolve the tension between public good and private ambition; it lets the two claims reinforce one another, so that taking power can be represented as both fulfillment and service.

Macbett's response marks the alliance's immediate change in balance. He asks Lady Duncan to let him be her slave; she raises him from his kneeling position, while he rolls at her feet. The stage darkens until only Lady Duncan's glistening body can be seen, and the lady in waiting invokes the triumph of love before the blackout. The scene ends not with a report that the promised political outcome has been achieved, but with Macbett physically and verbally yielded to the partnership's terms. His former scruple has given way to submission, while Lady Duncan has made the ambition that was hidden in him into an openly shared undertaking.

The Alliance at Court

Elsewhere, the partnership also appears in the handling of Banco's disappointed expectations. After Duncan fails to provide the reward Banco believes was promised, Macbett tells him that Lady Duncan is concerned and upset by the king's treatment of him. Macbett says he suggested that she intervene and that they have both pleaded Banco's case. This account presents the alliance as active beyond the scene of seduction: Macbett and Lady Duncan can coordinate their approaches to Duncan and position themselves as advocates for a third party.

When Banco asks why they should continue after their efforts have failed, Macbett proposes stronger arguments and says they will try again if necessary. The exchange does not specify what those arguments will be, so it does not establish that Lady Duncan participates in a particular later action. It does, however, place their cooperation within a political environment where Duncan's refusal of a reward generates pressure and where Macbett contemplates escalating persuasion. Set beside Lady Duncan's earlier offer of a dagger and shared rise to power, this episode shows the alliance operating in two registers: public intervention at court and a more radical private compact founded on ambition, intimacy, and the promise of sovereignty.
