Enrique Vi by William Shakespeare

A sweeping chronicle of a weak young king whose inability to control ambitious nobles plunges the realm into factional violence: competing Lancastrian and Yorkist factions, opportunistic magnates, shifting loyalties, military disasters, and the rise and fall of bold commanders drive a country toward chaos, betrayals, and civil war, with dramatic episodes—including the capture and martyrdom of a charismatic foreign warrior—that reveal how personal ambition and political failure destroy order and seed dynastic conflict.
