Question: What tragedy by William Shakespeare involves a norwegian crown prince and a character named "Horatio"?
Related documents: [0]  [DOC] Horatio is a character in William Shakespeare's tragedy "Hamlet". Horatio's origins are unknown, although he was present on the battlefield when Hamlet's father defeated 'the ambitious Norway', Fortinbras (the king), and attended Wittenberg University with Prince Hamlet. Horatio is evidently not directly involved in the intrigue at the Danish court; thus, he makes a good foil or sounding board for Prince Hamlet. He is often not identified as any specific court position, but simply as "friend to Hamlet." [END] 
[1]  [DOC] Fortinbras is either of two minor fictional characters from William Shakespeare's tragedy "Hamlet". The more notable is a Norwegian crown prince with a few brief scenes in the play, who delivers the final lines that represent a hopeful future for the monarchy of Denmark and its subjects. Fortinbras is also the name of the former king of Norway and father of the crown prince Fortinbras. King Fortinbras was slain in the play's antecedent action in battle with King Hamlet. The battle between the two is described by Horatio in Act One, Scene One (I,i) of the play. [END]
