In William Shakespeare's play, Henry VI Part III, York has taken the crown of England after the wake of the victory at St. Albans.
Henry arranges to meet with York, where he presents an offer York can't refuse. He offers that Henry continues to rule England until his death, with the crown passing to the house of York. Queen Margaret is angry and hates the idea that her son, the Prince of Wales will never be king.
Queen Margaret herself leads an army that defeats the Yorkists, and kills the Duke of York and his youngest son Rutland at Sandal Castle. After a regrouping though, the Yorkists chase Margaret and Henry who flee to France and Scotland and Edward, the eldest son of the dead York assumes the title of King of England.
Upon a secret return to England, Henry is captured by Edward and is imprisoned in the Tower of London, and Margaret is begging the King of France to come to her husband's rescue.
As a last ditch attempt, Warwick tries to set up a marriage between Edward and Henry's sister-in-law, Bona. Henry agrees with this and announces his allegiance to Edward until he hears soon afterward that Edward has married the woman he loves, Lady Grey.
Warwick, who feels betrayed by this, joins forces with Margaret.
Meanwhile, the York brothers are growing apart. Richard wants the throne for himself and the Duke of Clarence ends up also taking Margaret's side along with the French and Warwick.
Edward is soon captured by Warwick and Henry is temporarily restored to the throne until Richard rescues his brother and gathers an army which includes his brother the Duke of Clarence to fight Warwick.
Warwick is defeated and killed by Edward. The French troops attempt to come to the rescue but Margaret and her son the Prince of Wales are captured and the Prince is murdered by the York's. Edward does grant mercy to Margaret though.
Richard also believes that his brother will be lenient on Henry so he pays Henry a visit in the Tower of London. Henry foretells Richard's awful future and Richard out of anger kills him and plans to take the throne of England for himself.
