Prince Hamlet is the title character and protagonist of William Shakespeare's tragedy Hamlet (1599–1601). He is the Prince of Denmark, nephew to the usurping Claudius, and son of King Hamlet, the previous King of Denmark. At the beginning of the play, he is conflicted whether, and how, to avenge the murder of his father, and struggles with his own sanity along the way. By the end of the tragedy, Hamlet has caused the deaths of Polonius, Laertes, Claudius, and Rosencrantz and Guildenstern, two acquaintances of his from childhood. He is also indirectly involved in the deaths of his love Ophelia (drowning) and of his mother Gertrude.

William Shakespeare was an English playwright, poet, and actor. He is widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon". His extant works, including collaborations, consist of some 39 plays, 154 sonnets, three long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright. Shakespeare remains arguably the most influential writer in the English language, and his works continue to be studied and reinterpreted.
