The name of Henry V is associated with the most significant events in English and French history of the 15th century: the usurpation of the royal throne by England by the Lancaster dynasty, the suppression of political conspiracies and social unrest, victorious campaigns in France, but most importantly, the triumph over the French army at the Battle of Agincourt and the establishment of a dual monarchy in France (1420). This list alone was enough to turn Henry V into a national English hero, a political and military genius of the era.
