Polonius is the chief counselor to the king, and also the father of Ophelia and Laertes.
Hamlets Father
Hamlet's father was also named Hamlet. Throughout the play they may refer to them as "Old Hamlet" and "Young Hamlet," or, in the father's case "Denmark" as a reference to his royalty and the country he ruled.
Ophelia's father is Polonius, who is Claudius' advisor. Polonius is killed by Hamlet when he is hiding behind a tapestry, spying on Hamlet as he talks to his mother, Gertrude. After Polonius' death, Ophelia goes mad and eventually dies after she falls from a tree into a brook and drowns.
Hamlet's uncle Claudius.
When Gertrude inadvertently drinks the poison and dies, Hamlet is at last able to bring himself to kill Claudius, and the king is felled by his own cowardly machination. Addition: Act 5, Scene II: "HAMLET The point!--envenom'd too! Then, venom, to thy work. Stabs KING CLAUDIUS All Treason! treason! KING CLAUDIUS O, yet defend me, friends; I am but hurt. HAMLET Here, thou incestuous, murderous, damned Dane, Drink off this potion. Is thy union here? Follow my mother. KING CLAUDIUS dies"
when hamlet saw his father's ghost, the ghost said that hamlet's uncle (which he was king during that time) put poison in hamlet's father's ear while he was sleeping so he could become king. so it was hamlet's uncle
Hamlet's goal is to avenge his father's murder, by proving his uncle, his new king, and step father as a killer.
King Claudius. He's now also his father, sort of. He's a villain.
Claudius-who is Hamlets uncle, gets married to getrude and then becomes the new king
Prior to Hamlet's entry into Gertrude's (Hamlet's mother) chamber, Polonius is having a discussion with the queen. As Hamlet enters his mother's room rather abruptly, Polonius chooses to hide behind a tapestry on the wall. When Hamlet begins to threaten his mother, Polonius believes Hamlet is trying to kill her, and so Polonius cries for help. Hamlet "thinking it was King Claudius" (it is unclear as to whether he actually believes its the King or not), stabs Polonius through the tapestry, killing him. As he dies he lets out his iconically obvious line "Oh, I am slain".
