who was Claudius?

Claudius

Old Hamlet's brother, Hamlet's uncle, and Gertrude's newlywed husband. He murdered his brother in order to seize the throne and subsequently married Gertrude, his erstwhile sister-in-law. Claudius appears to be a rather dull man who is fond of the pleasures of the flesh, sex and drinking. Only as the play goes on do we become certain that he is indeed guilty of murder and usurpation. Claudius is the only character aside from Hamlet to have a soliloquy in the play. When he is convinced that Hamlet has found him out, Claudius eventually schemes to have his nephew-cum-son murdered.
