What Is Hamlet About? Shakespeare's Tragedy of Revenge and Doubt Explained

Hamlet is a tragedy by William Shakespeare, written around 1599–1601, about Prince Hamlet of Denmark, who is told by his father's ghost that his uncle Claudius murdered the old king to take the throne and marry the queen. Hamlet is ordered to take revenge, but instead of acting quickly he thinks, doubts, pretends to be mad and questions what life and death really mean. It is Shakespeare's longest play and is often called one of the most powerful and influential works in world literature.

The plot in brief

The play opens at night on the walls of Elsinore Castle, where guards have seen a ghost that looks like the dead King Hamlet. Prince Hamlet speaks with the ghost and learns that his uncle Claudius poisoned the king by pouring poison into his ear while he slept. Claudius is now king and has married Hamlet's mother, Gertrude.

Hamlet decides to act strangely, so that people will think he is mad while he looks for proof. He arranges for travelling actors to perform a play that copies the murder, and watches Claudius's reaction. When the king rushes out, Hamlet becomes sure of his guilt.

Things then go badly wrong. Hamlet accidentally kills Polonius, the king's adviser, who is hiding behind a curtain. Polonius's daughter Ophelia, whom Hamlet once loved, loses her mind and drowns. Her brother Laertes returns, wanting revenge on Hamlet. Claudius sets up a fencing match in which Laertes uses a poisoned sword, with a poisoned drink as a back-up plan. In the final scene Gertrude, Laertes, Claudius and Hamlet all die, and the Norwegian prince Fortinbras arrives to take over Denmark.

Why does Hamlet wait?

The central question of the play is why Hamlet delays. He has a clear duty, but he keeps asking whether the ghost is honest, whether revenge is right and whether any action has meaning. Readers have argued about this for centuries. Some see a man who thinks too much to act; others see a careful mind in a corrupt world where every choice is dangerous. This uncertainty is a big part of why the play feels so modern.

"To be, or not to be"

The most famous lines in English drama come from Hamlet's speech in Act 3, which begins "To be, or not to be, that is the question." In it, Hamlet weighs whether it is better to endure life's suffering or to end it, and wonders what might come after death. The speech is quoted, parodied and borrowed everywhere, from cartoons to advertisements, often by people who have never read the play.

Words and phrases from Hamlet

Hamlet has given English a surprising number of everyday expressions. Phrases often traced to the play include "something is rotten in the state of Denmark", "brevity is the soul of wit", "the lady doth protest too much" and "to thine own self be true". Many English speakers use them without knowing where they came from.

Why it still matters

The play has been performed, filmed and adapted countless times, and it has inspired stories in many cultures. Its questions about grief, duty, doubt and honesty still speak to people today. For language learners, reading even a few famous scenes in a modern-English edition is a rewarding way to meet the roots of everyday English.
