The first act opens on the battlements of Elsinore Castle, where guards have spotted a ghost resembling the recently deceased King Hamlet for two consecutive nights. They bring Hamlet’s trusted friend Horatio to see the ghost, and when it appears a third time, they decide to tell Hamlet, who has been openly grieving his father’s death and resenting his mother Gertrude’s hasty marriage to Claudius, his father’s brother and the new king. Use this before class to make sure you can follow the act’s chronological flow when your teacher references specific scenes.
Claudius presents as a confident, capable king in his first public speech, addressing the threat of invasion from Norway and framing his marriage to Gertrude as a practical choice for the country’s stability. Hamlet is established as a thoughtful, grief-stricken outsider, openly rejecting the court’s expectation that he move on from his father’s death quickly. Write down one adjective to describe each core character based on their first act dialogue to build your character note bank.
When Hamlet meets the ghost on the battlements, the spirit claims he was murdered by Claudius, who poured poison in his ear while he slept in the garden. The ghost commands Hamlet to avenge his murder, but tells him not to harm Gertrude, leaving her to be judged by heaven. Highlight the ghost’s specific instructions to Hamlet so you can track how closely Hamlet follows them in later acts.
After speaking with the ghost, Hamlet tells Horatio and the guards he plans to feign madness, or put on an “antic disposition,” to investigate Claudius’s guilt without raising suspicion. He makes them swear not to tell anyone about the ghost or his plan, even if he acts strangely in the coming weeks. Jot down one reason why feigning madness might be a better choice than confronting Claudius directly to reference in discussion.
The first act introduces all core themes that run through the rest of the play: the tension between public duty and private grief, the danger of deception, the ambiguity of supernatural evidence, and the moral weight of revenge. Every conflict that unfolds in later acts traces back to choices made in these opening scenes. Note one theme that stands out to you most so you can track its development as you read the rest of the play.
Elizabethan audiences believed ghosts could be either spirits of the dead returning to ask for justice, or devils in disguise sent to tempt people to sin. Hamlet’s doubt about the ghost’s true identity, and his choice to verify its claims before acting, would have made sense to contemporary viewers as a cautious, moral choice. Look up one more detail about Elizabethan beliefs about ghosts to add context to your next essay draft.
The first act establishes that Gertrude marries Claudius within a month of King Hamlet’s funeral, a timeline that is the source of much of Hamlet’s anger and resentment.
The guards know Hamlet is still grieving his father deeply, and they believe he will take the ghost’s appearance seriously, while Claudius has already dismissed formal mourning for King Hamlet and may not believe their report.
Hamlet says he will pretend to be mad to investigate Claudius’s guilt, which shows he does not take the ghost’s claim at face value and wants proof before he takes any violent action.
Fortinbras, the prince of Norway, is raising an army to invade Denmark and reclaim land his father lost to King Hamlet years earlier, establishing an external threat to Elsinore that runs parallel to the internal court conflict.
