Ghost (Hamlet) in the context of "Aurvandill"

The Tragedy of Hamlet, Prince of Denmark, often shortened to Hamlet (/ˈhæmlɪt/), is a tragedy written by William Shakespeare sometime between 1599 and 1601. It is Shakespeare's longest play. Set in Denmark, the play depicts Prince Hamlet and his attempts to exact revenge against his uncle, Claudius, who has murdered Hamlet's father in order to seize his throne and marry Hamlet's mother.

Hamlet is considered among the "most powerful and influential tragedies in the English language", with a story capable of "seemingly endless retelling and adaptation by others." It is widely considered one of the greatest plays of all time. Three different early versions of the play are extant: the First Quarto (Q1, 1603); the Second Quarto (Q2, 1604); and the First Folio (F1, 1623). Each version includes lines and passages missing from the others. Many works have been pointed to as possible sources for Shakespeare's play, from ancient Greek tragedies to Elizabethan dramas.

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.

In William Shakespeare's play Hamlet, Gertrude is Hamlet's mother and Queen of Denmark. Her relationship with Hamlet is somewhat turbulent, since he resents her marrying her husband's brother Claudius after he murdered the king (young Hamlet's father, King Hamlet). Gertrude reveals no guilt in her marriage with Claudius after the recent murder of her husband, and Hamlet begins to show signs of jealousy towards Claudius. According to Hamlet, she scarcely mourned her husband's death before marrying Claudius.

Her name may derive from Gertrude of Bavaria, who was Queen of Denmark in the late 12th century.
