How ambition drives Macbeth
Ambition is the fatal flaw at the centre of the play, the hamartia that brings the tragic hero down. What makes Shakespeare's treatment of it so clever is that Macbeth is no fool: he knows his ambitions are wrong, knows of the devastating consequences that are sure to occur, yet he acts upon it anyway. This is central to the idea of tragedy: seeing an easy preventative, yet watching it fall from your grasp.
Ambition is something that never rests. Getting the crown does not satisfy Macbeth, but rather it leads him down a path of paranoia, ignorance, and thoughtless violence. We see his ambitions as the catalyst for feelings of guilt and nihilism, as he realises that they were always impossible to achieve. Ambition, like the Witches, is proven to be duplicitous and untrustworthy: an appearance which obscures the stark realities of usurping the natural order.
Key ambition quotes in Macbeth
“Stars, hide your fires; / Let not light see my black and deep desires”
Where: Act 1 Scene 4The first sign of dangerous ambition. Macbeth wants to hide his 'black and deep desires' from the light; from God. Argue that his ambition is conscious and guilty from the start, and that he already senses it is something to conceal. A great opening quote for the theme.
“Thou wouldst be great; / Art not without ambition, but without / The illness should attend it”
Where: Act 1 Scene 5Lady Macbeth's diagnosis of her husband. He has ambition but not the ruthlessness ('illness') to act on it. Use it to show that ambition alone is not initially enough. It needs a spur, one that Lady Macbeth, through threatening his masculine power, provides.
“The Prince of Cumberland! that is a step / On which I must fall down, or else o'erleap”
Where: Act 1 Scene 4Where ambition meets an obstacle. This is another great example of Macbeth being conscious of his ambition, and its consequences, from the start. The verb 'o'erleap' foreshadows his own overreaching later.
“I have no spur / To prick the sides of my intent, but only / Vaulting ambition, which o'erleaps itself”
Where: Act 1 Scene 7The single most important quote for the theme. Macbeth admits he has no reason to kill Duncan except pure ambition, pictured as a rider leaping too high and falling. This is his self-diagnosis and the play's warning: ambition that overreaches destroys itself.
“To be thus is nothing, / But to be safely thus”
Where: Act 3 Scene 1Ambition after the crown is won. Being king ('thus') is worthless to Macbeth unless he is 'safely' king, which he never can be. Your key quote for the idea that ambition is something that never rests. It brings with it only a new fear, and drives him to murder Banquo next.
How ambition develops across the play
Track ambition across the five acts and you have the shape of the whole play. In Act 1 it is born: the witches plant the idea, and Macbeth's mind leaps to murder while he tries to hide his 'black and deep desires'. Lady Macbeth then supplies the ruthlessness he lacks. By Act 2, ambition has become action, and Duncan is dead.
In Act 3, safe on the throne, Macbeth finds that ambition has only made him afraid, and he has Banquo killed to protect a crown he cannot enjoy. By Acts 4 and 5, ambition has hardened into pure tyranny: he slaughters Macduff's family and clings to the witches' promises. The final irony is that he ends with nothing, delivering the bleak 'Tomorrow, and tomorrow, and tomorrow' speech over the ruins of everything his ambition built. The message is complete: 'vaulting ambition' really does 'o'erleap itself'.
Using ambition in the exam
Ambition was the question that I was assessed on in 2025!
I think the strongest ambition answers do two things: they trace how the ambition changes, and they show how it interacts with the play's other themes. In my response, I compared his soliloquy in Act 1 Scene 7 with his final soliloquy in Act 5 Scene 5 to demonstrate how ambition leads to corruption, both in the natural world and within the mind.
Show the arc of Macbeth's ambition: from a hidden 'black and deep desire' to a never-ending hunger ('To be thus is nothing, / But to be safely thus').
Connecting ambition to context is key: Macbeth's ambition is his hamartia, and his overreaching would remind a Jacobean audience of the danger of disturbing the God-given order.

Revise ambition alongside the play's other big ideas: guilt, which is the price of overreaching ambition, and the supernatural, which first plants it. See how they connect on the Macbeth themes page and secure your lines with the key quotes page.
