Henry V (16 September 1386 - 31 August 1422) was one of the most significant English warrior kings of the 15th century. He was born at Monmouth, Wales, in the tower above the gatehouse of Monmouth Castle, and reigned as King of England from 1413 to 1422. Henry was the son of Henry of Bolingbroke, later Henry IV, and sixteen-year-old Mary de Bohun, who was to die in childbirth at 26, before Bolingbroke became king. At the time of his birth during the reign of Richard II, Henry was fairly far removed from the throne, preceded by the king and another collateral line of heirs. The precise date and even year of his birth are therefore not definitely recorded; sources offer as the most likely either 9 August or 16 September, in 1386 or 1387. By the time Henry died, he had not only consolidated power as the King of England but had also effectively accomplished what generations of his ancestors had failed to achieve through decades of war: unification of the crowns of England and France in a single person. In 2002, he was ranked 72nd in the 100 Greatest Britons
