Henry V (1387-1422), the eldest son of Henry IV, was crowned in 1413. Henry V followed his father's policy toward the Lollards. Many of them were put to death.
Henry renewed the Hundred Years' War with France, which had begun during the reign of Edward III. He was determined to make good Edward's old claim to the French throne. In 1415, Henry won one of the most famous victories in English history. His small army crushed a host of French lords and knights at Agincourt. Five years later, Henry married the daughter of Charles VI, King of France. By the Treaty of Troyes, Henry forced Charles to declare him heir to the French crown. When Henry died two years later, he had won the entire northern half of France. He appears as Prince Hal in Shakespeare's Henry IV, Part I and Part II.
