The Tragedy of Hamlet, Prince of Denmark, often shortened to Hamlet, is a tragedy written by William Shakespeare at an uncertain date between 1599 and 1602. Set in the Kingdom of Denmark, the play dramatises the revenge Prince Hamlet is called to wreak upon his uncle, Claudius, by the ghost of Hamlet's father, King Hamlet. Claudius had murdered his own brother and seized the throne, also marrying his deceased brother's widow. Hamlet is Shakespeare's longest play, and is ranked among the most powerful and influential tragedies in English literature, with a story capable of "seemingly endless retelling and adaptation by others". The play likely was one of Shakespeare's most popular works during his lifetime, and still ranks among his most performed, topping the performance list of the Royal Shakespeare Company and its predecessors in Stratford-upon-Avon since 1879. It has inspired many other writers - from Johann Wolfgang von Goethe and Charles Dickens to James Joyce and Iris Murdoch - and has been described as "the world's most filmed story after Cinderella".
