King Claudius is a fictional character and the main antagonist of William Shakespeare's tragedy Hamlet. He is the brother to King Hamlet, second husband to Gertrude and uncle and later stepfather to Prince Hamlet. He obtained the throne of Denmark by murdering his brother with poison and then marrying the late king's widow. He is loosely based on the Jutish chieftain Feng who appears in Chronicon Lethrense and in Saxo Grammaticus' Gesta Danorum. There has never been an actual Danish King of that name. Overview Claudius is seen at the beginning of the play to be a capable monarch as he deals diplomatically with such issues as the military threat from Norway and Hamlet's depression. It is not until the appearance of King Hamlet's Ghost in the courtyard that the audience questions his motives. During the play's progression he takes a turn for the worse by first resorting to spying, and, when that fails, murder.

If he were to truly repent, he would have to confess his sin and give up all he achieved through it, which he chooses not to do. Despite his remorse, the king still seeks Hamlet's death in an effort to save both his throne and his life, as he believes the prince is now aware of his part in King Hamlet's death. Hamlet is ready to kill him, only to back down, feeling that to kill the king in such a way would contradict the revenge conditions given to him by his father, who commanded him specifically: "Taint not thy mind." When Laertes seeks revenge for his father Polonius' death at Hamlet's hands, Claudius finally concocts a 'surefire' plan to deal with Hamlet once and for all. He arranges a fencing match between Hamlet and Laertes, but plots with Laertes to poison his foil and give Hamlet a poisoned drink. The king's plan fails; Queen Gertrude drinks from the poisoned chalice instead of
