Question: What tragedy by William Shakespeare involves a norwegian crown prince and a character named "Horatio"?

full_context: Document 1: Kronborg: Kronborg is a castle and stronghold in the town of Helsingør, Denmark. Immortalized as Elsinore in William Shakespeare's play "Hamlet", Kronborg is one of the most important Renaissance castles in Northern Europe and has been added to UNESCO's World Heritage Sites list (2000).
Document 2: Fortinbras: 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.
Document 3: Literary influence of Hamlet: William Shakespeare's Hamlet is a tragedy, believed to have been written between 1599 and 1601. It tells the story of Hamlet, Prince of Denmark—who takes revenge on the current king (Hamlet's uncle) for killing the previous king (Hamlet's father) and for marrying his father's widow (Hamlet's mother)—and it charts the course of his real or feigned madness. "Hamlet" is the longest play—and Hamlet is the largest part—in the entire Shakespeare canon. Critics say that "Hamlet" "offers the greatest exhibition of Shakespeare's powers".
Document 4: Banquo: Lord Banquo , the Thane of Lochaber, is a character in William Shakespeare's 1606 play "Macbeth". In the play, he is at first an ally to Macbeth (both are generals in the King's army) and they are together when they meet the Three Witches. After prophesying that Macbeth will become king, the witches tell Banquo that he will not be king himself, but that his descendants will be. Later, Macbeth in his lust for power sees Banquo as a threat and has him murdered; Banquo's son, Fleance, escapes. Banquo's ghost returns in a later scene, causing Macbeth to react with alarm during a public feast.
Document 5: Gyldenstierne (noble family): Gyldenstjerne, also spelled "Gyldenstierne" and in Swedish "Gyllenstierna" (English: "Golden Star"), is a Danish, Norwegian, and Swedish noble family divided into various branches and ranks. It is one of the oldest noble families in Scandinavia. The family surname appears, in the form of "Guildenstern", in William Shakespeare's tragedy "The Tragedy of Hamlet, Prince of Denmark" (see Rosencrantz and Guildenstern).The surname should not be confused with Gyldensteen ("Golden Stone"), the name of another short-lived Danish noble family, first recorded in 1717 and which became extinct in 1749.
Document 6: King Claudius: King Claudius is a fictional character and the primary antagonist of William Shakespeare's tragedy "Hamlet". He is the brother to King Hamlet, second husband to Gertrude and uncle and later stepfather to Hamlet. He obtained the throne of Denmark by murdering his own 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 had never been an actual Danish King of that name.
Document 7: Characters in Romeo and Juliet: Prince Escalus, the Prince of Verona, is the desperate resolver of the feuding families. He is based on the actual Scaligeri family which ruled Verona, possibly on Bartolomeo I. Escalus is the voice of authority in Verona. He appears only three times within the text and only to administer justice following major events in the feud between the Capulet and Montague families. He first punishes Capulet and Montague for the quarrel between Tybalt, Benvolio, and a handful of servants. He returns too late to stop the fatal brawls between Tybalt and Mercutio and, subsequently, Tybalt and Romeo. Escalus is prepared to execute Romeo for his offence—Romeo's killing Tybalt—but lightens the sentence to lifetime banishment from Verona, when Benvolio insists that Tybalt started the quarrel by murdering Mercutio, a kinsman to the Prince. He yells at Lord Montague for engaging in the feud, which really is the root cause which led to Tybalt killing Mercutio. So, according to him, he lost his dear kinsman because of Lord Montague, so by exiling Romeo, Escalus gives him a 'taste of Montague's own medicine', to see how Montague feels when he loses a loved one. Prince Escalus returns in the final scene—V.iii—following the double suicide of Romeo and Juliet, and at last declares the Lords Montague and Capulet guilty of Romeo and Juliet's death, and angrily tells them that their totally useless feud resulted in the deaths of not only their own loved ones (Lady Montague, Romeo, Juliet, and Tybalt), but also in the deaths of Escalus' loved ones (Mercutio and Paris). He curses the feud that kills Romeo and Juliet whom he really feels sad for, just before the Lords come to peace with each other. In the end, Prince Escalus becomes very happy that the feud has finally ended, even if with a heavy price, since it ended late.
Document 8: King Duncan: King Duncan is a fictional character in Shakespeare's "Macbeth." He is the father of two youthful sons (Malcolm and Donalbain), and the victim of a well-plotted regicide in a power grab by his trusted captain Macbeth. The origin of the character lies in a narrative of the historical Donnchad mac Crinain, King of Scots, in Raphael Holinshed's 1587 "The Chronicles of England, Scotland, and Ireland," a history of Britain familiar to Shakespeare and his contemporaries. Unlike Holinshed's incompetent King Duncan (who is credited in the narrative with a "feeble and slothful administration"), Shakespeare's King Duncan is crafted as a sensitive, insightful, and generous father-figure whose murder grieves Scotland and is accounted the cause of turmoil in the natural world.
Document 9: Hamlet (1996 film): Hamlet is a 1996 film adaptation of William Shakespeare's play "Hamlet", adapted for the screen and directed by Kenneth Branagh, who also stars in the titular role as Prince Hamlet. The film also features Derek Jacobi as King Claudius, Julie Christie as Queen Gertrude, Kate Winslet as Ophelia, Michael Maloney as Laertes, Richard Briers as Polonius, and Nicholas Farrell as Horatio. Other notable appearances include Robin Williams, Gérard Depardieu, Jack Lemmon, Billy Crystal, Rufus Sewell, Charlton Heston, Richard Attenborough, Judi Dench, John Gielgud and Ken Dodd.
Document 10: Rosencrantz and Guildenstern: Rosencrantz and Guildenstern are characters in William Shakespeare's tragedy "Hamlet". They are childhood friends of Hamlet, summoned by King Claudius to distract the prince from his apparent madness and if possible to ascertain the cause of it. The characters were revived in W. S. Gilbert's satire, "Rosencrantz and Guildenstern", and as the alienated heroes of Tom Stoppard's absurdist play, "Rosencrantz and Guildenstern Are Dead", which was adapted into a film.
Document 11: To be, or not to be: To be, or not to be is the opening phrase of a soliloquy spoken by Prince Hamlet in the so-called "nunnery scene" of William Shakespeare's play "Hamlet". Act III, Scene I.
Document 12: Gertrude (Hamlet): 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.
Document 13: Falstaff: Sir John Falstaff is a fictional character who is mentioned in five plays by William Shakespeare and appears on stage in three of them. His significance as a fully developed character in Shakespeare is primarily formed in the plays "Henry IV, Part 1" and "Part 2", where he is a companion to Prince Hal, the future King Henry V. A notable eulogy for Falstaff is presented in Act II, Scene III of "Henry V", where Falstaff does not appear as a character on stage, as enacted by Mistress Quickly in terms that some scholars have ascribed to Plato's description of the death of Socrates after drinking hemlock. By comparison, in "The Merry Wives of Windsor", Falstaff is presented by Shakespeare as the buffoonish suitor of two married women.
Document 14: Laertes (Hamlet): Laertes is a character in William Shakespeare's play "Hamlet". His name is taken from the father of Odysseus in Homer's Odyssey. Laertes is the son of Polonius and the brother of Ophelia. In the final scene, he kills Hamlet with a poisoned sword to avenge the deaths of his father and sister, for which he blamed Hamlet. While dying of the same poison, he implicates King Claudius. The Laertes character is thought to be originated by Shakespeare, as there is no equivalent character in any of the known sources for the play.
Document 15: Horatio (Hamlet): 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."
