The seven main themes in Hamlet are revenge and justice, madness and folly, appearance vs reality, death and mortality, action vs inaction, disease and corruption, and gender and power. Each is analysed in depth in this study guide, with close reading, key quotes, and modern English verse translation.

Revenge is the play's driving theme, but Shakespeare uses it as a frame for deeper questions about mortality, moral action, and the limits of certainty. Hamlet's hesitation is what makes the play distinctive: a revenge tragedy whose hero refuses, for almost five acts, to behave like one.

Revenge is examined through three young men avenging fathers — Hamlet, Laertes, and Fortinbras — each responding differently. Where Laertes acts on impulse and Fortinbras with calculated military purpose, Hamlet hesitates, weighing the moral, theological, and philosophical cost of killing Claudius. The play tests whether revenge is justice, sin, duty, or merely another form of corruption.

Madness in Hamlet is both feigned and real. Hamlet adopts an "antic disposition" to investigate Claudius safely, but his grief, isolation, and encounters with the Ghost push him toward genuine psychological fracture. Ophelia's madness, by contrast, is wholly real — a collapse triggered by her father's murder and Hamlet's rejection — and offers a tragic mirror to Hamlet's performed instability.

Mortality runs through the play from the opening Ghost to the closing pile of bodies. The "To be, or not to be" soliloquy meditates on suicide and the unknown after death; the graveyard scene confronts Hamlet with the physical reality of decay through Yorick's skull. Shakespeare presents death as the great leveller — kings, jesters, and lovers all reduced to dust.

Almost no one in Hamlet is what they appear to be. Claudius is a smiling king and a murderer; Hamlet performs madness while concealing intelligence; Polonius preaches honesty while spying; Ophelia is used as bait. The theme drives the play's preoccupation with surveillance, performance, and the difficulty of knowing the truth — including the truth about oneself.

Gender is a central battlefield in the play. Hamlet's misogyny — triggered by Gertrude's hasty remarriage and turned cruelly on Ophelia — reflects a court that equates female sexuality with corruption. Both women are denied full voice: Gertrude's inner life is glimpsed only briefly, and Ophelia is silenced into madness after being weaponised by her father and the king. The play raises sharp questions about female agency in a world that treats women as instruments.
