The Prince of Denmark, the title character, and the protagonist. About thirty years old at the start of the play, Hamlet is the son of Queen Gertrude and the late King Hamlet, and the nephew of the present king, Claudius. Hamlet is melancholy, bitter, and cynical, full of hatred for his uncle’s scheming and disgust for his mother’s sexuality. A reflective and thoughtful young man who has studied at the University of Wittenberg, Hamlet is often indecisive and hesitant, but at other times prone to rash and impulsive acts.
The King of Denmark, Hamlet’s uncle and the play’s antagonist. The villain of the play, Claudius is a calculating, ambitious politician, driven by his sexual appetites and his lust for power, but he occasionally shows signs of guilt and human feeling—his love for Gertrude, for instance, seems sincere.
The Queen of Denmark, Hamlet’s mother, recently married to Claudius. Gertrude loves Hamlet deeply, but she is a shallow, weak woman who seeks affection and status more urgently than moral rectitude or truth.
The Lord Chamberlain of Claudius’s court, a pompous, conniving old man. Polonius is the father of Laertes and Ophelia.
Polonius’s daughter, a beautiful young woman with whom Hamlet has been in love. Ophelia is a sweet and innocent young girl, who obeys her father and her brother, Laertes. Dependent on men to tell her how to behave, she gives in to Polonius’s schemes to spy on Hamlet. Even in her lapse into madness and death, she remains maidenly, singing songs about flowers and finally drowning in the river amid the flower garlands she had gathered.
Polonius’s son and Ophelia’s brother, a young man who spends much of the play in France. Passionate and quick to action, Laertes is clearly a foil for the reflective Hamlet.
The specter of Hamlet’s recently deceased father. The Ghost, who claims to have been murdered by Claudius, calls upon Hamlet to avenge him. However, it is not entirely certain whether the Ghost is what it appears to be, or whether it is something else. Hamlet speculates that the Ghost might be a devil sent to deceive him and tempt him into murder, and the question of what the Ghost is or where it comes from is never definitively resolved.
Horatio
Hamlet’s close friend, who studied with the prince at the university in Wittenberg. Horatio is loyal and helpful to Hamlet throughout the play. After Hamlet’s death, Horatio remains alive to tell Hamlet’s story.
Fortinbras
The young Prince of Norway, whose father the king (also named Fortinbras) was killed by Hamlet’s father (also named Hamlet). Now Fortinbras wishes to attack Denmark to avenge his father’s honor, making him another foil for Prince Hamlet.
Rosencrantz and Guildenstern
Two slightly bumbling courtiers, former friends of Hamlet from Wittenberg, who are summoned by Claudius and Gertrude to discover the cause of Hamlet’s strange behavior.
Osric
The foolish courtier who summons Hamlet to his duel with Laertes.
Courtiers whom Claudius sends to Norway to persuade the king to prevent Fortinbras from attacking.
The officers who first see the ghost walking the ramparts of Elsinore and who summon Horatio to witness it. Marcellus is present when Hamlet first encounters the ghost.
Francisco
A soldier and guardsman at Elsinore.
Reynaldo
Polonius’s servant, who is sent to France by Polonius to check up on and spy on Laertes.
Many people have seen Hamlet as a play about indecisiveness, and thus about Hamlet’s failure to act appropriately. It might be more interesting to consider that the play shows us how many uncertainties our lives are built upon, and how many unknown quantities are taken for granted when people act or when they evaluate one another’s actions.
In Hamlet, the question of how to act is affected not only by rational considerations, such as the need for certainty, but also by emotional, ethical, and psychological factors. Hamlet himself appears to distrust the idea that it’s even possible to act in a controlled, purposeful way. When he does act, he prefers to do it blindly, recklessly, and violently.
One of the central questions of Hamlet is whether the main character has lost his mind or is only pretending to be mad. Hamlet’s erratic behavior and nonsensical speech can be interpreted as a ruse to get the other characters to believe he’s gone mad. On the other hand, his behavior may be a logical response to the “mad” situation he finds himself in – his father has been murdered by his uncle, who is now his stepfather.
Elsinore Castle in Denmark.
The ghost of the King of Denmark tells his son Hamlet to avenge his murder by killing the new king, Hamlet's uncle. Hamlet feigns madness, contemplates life and death, and seeks revenge. His uncle, fearing for his life, also devises plots to kill Hamlet.
