Henry VI is an infant in the opening scene of the trilogy named for him; in its closing scene he dies. From his first appearance on the stage he is bookish and pious. "Marriage, Uncle! Alas, my years are young! / And fitter is my study and my books / Than wanton dalliance with a paramour." His nobles choke and splutter at the news of England's shrinking authority in France; Henry shrugs and says they must accept God's will.
These are not, as you might imagine, traits they find very kingly. "Be patient," Henry counsels Lord Clifford. "Patience is for poltroons," Clifford retorts. When the sparks of discontent ignite a civil war, Henry is even more ill-suited to lead.
