Full Name: Henry V of England; Profession: King of England, Lord of Ireland, Duke of Aquitaine, medieval warrior king and statesman renowned for his leadership in the Hundred Years’ War—especially his victory at the Battle of Agincourt—and for promoting the use of English in royal government and administration, which helped shape early English national identity; Nationality: English (a Lancastrian king of England, born in Wales but ruling as an English monarch); Born: 16 September 1386; Birthplace: Monmouth Castle, Monmouth, Monmouthshire, Wales (known in his youth as “Henry of Monmouth” because he was born in the tower above the gatehouse of Monmouth Castle); Generation: Late medieval 14th–15th-century Plantagenet–Lancastrian royal generation, coming of age during the reign of his cousin Richard II and rising to the throne in 1413 at the height of dynastic struggles and the Hundred Years’ War; Chinese Zodiac: Dragon (1386 corresponds to the Fire Dragon year, associated with power, leadership, and bold action); Zodiac Sign: Virgo (the Sun is in Virgo for birthdays on September 16, placing Henry V in late Virgo with its analytical, disciplined, and service-oriented qualities); Age in 2026: 640 (he would have turned 640 years old on 16 September 2026, counting from his birth in 1386); Marital Status: Married (spouse Catherine of Valois, French princess and queen consort of England, whom he wed at Troyes on 2 June 1420 as part of the Treaty of Troyes that bound the crowns of England and France); Children: One legitimate son, Henry VI of England, born in December 1421 at Windsor Castle and crowned as infant king of England (and, by treaty, king of France) after Henry V’s death, thus continuing the Lancastrian line and inheriting his father’s vast but fragile Anglo-French claims; Description: Henry V—often called Henry of Monmouth—was a pivotal Lancastrian monarch whose relatively short reign from 1413 to 1422 left an enduring mark on European history, as he consolidated royal authority at home by attempting to reconcile factions divided by his father Henry IV’s usurpation, made English the language of government instead of French, and projected English power abroad through audacious campaigns in France, culminating in his stunning victory over a larger French army at Agincourt in 1415, a feat that cemented his legend as one of England’s greatest warrior kings and enabled the Treaty of Troyes, which recognized him as heir to the French throne and husband of Catherine of Valois; his combination of personal piety, military ruthlessness, and political pragmatism has fascinated historians, and his life has been immortalized in Shakespeare’s plays and countless later adaptations that portray him as the archetype of the charismatic, conquering king whose triumphs on the battlefield temporarily transformed England into one of the strongest kingdoms in Europe before his early death changed the course of the Hundred Years’ War; Cause of Death: Died on 31 August 1422 at Château de Vincennes near Paris, France, from illness widely believed to be dysentery contracted during the protracted siege of Meaux in the Hundred Years’ War, a deadly infection that struck him down in his mid-thirties just months before he could fully secure his dual monarchy over England and France, leaving his infant son Henry VI to inherit a vast but unstable empire
