born Sept. 16?, 1387, Monmouth, Monmouthshire, Wales

died Aug. 31, 1422, Bois de Vincennes, Fr.

King of England (1413–22) of the House of Lancaster .

The eldest son of Henry IV , he fought Welsh rebels (1403–08). As king he harshly suppressed a Lollard uprising (1414) and a Yorkist conspiracy (1415). He claimed extensive lands in France and launched an invasion (1415), and his stunning victory at the Battle of Agincourt made England one of the greatest powers in Europe. His continuing victories forced the French to sign the Treaty of Troyes (1420), in which Henry was named heir to the French throne and regent of France. He married Catherine, daughter of the French king, but died of camp fever before he could return home.
