What happens in Henry IV, Part 1

King Henry IV opens the play tired and guilt-stricken, hoping to march a crusade to the Holy Land. He took his crown from Richard II, and his conscience never lets him forget it. Before he can plan the journey, two messengers arrive with bad news. Welsh rebels under Glendower have killed a thousand English soldiers. In the north, young Harry Percy — everyone calls him Hotspur — has crushed the Scots at Holmedon. Henry envies Hotspur’s valor and wishes such a son were his own. Then he learns that Hotspur is keeping his Scottish prisoners and refusing to hand them over.

Henry’s actual son, Prince Hal, spends his days drinking in the Boar’s Head Tavern with the fat, witty knight Sir John Falstaff. They joke about robbery and Hal’s wild future. Yet Hal is not as lost as he seems. Alone, he tells us his plan: he is playing the wastrel on purpose, and one day he will throw off the act and shine. When Falstaff and his friends rob some travelers at Gads Hill, Hal and Poins rob the robbers, then enjoy watching Falstaff invent ever taller lies about the fight.

At court, Hotspur’s anger hardens into rebellion. His uncle Worcester and his father Northumberland persuade him to join Glendower and Mortimer against the king they once helped to power. The rebels meet at Bangor to carve up England in advance, though Hotspur nearly wrecks the alliance with his rudeness. Meanwhile Henry summons Hal and accuses him of shaming the crown. Stung, Hal swears to redeem himself by killing Hotspur in battle, and his father, moved, gives him command of troops.

The two armies converge on Shrewsbury, and the rebels’ luck turns. Northumberland falls sick and cannot bring his men. Glendower is delayed for two weeks. Their forces are tired and outnumbered, yet Hotspur insists on fighting at once. The night before the battle, Henry sends Worcester an offer of pardon if the rebels disband. Worcester, certain the king would never truly forgive them, hides the offer from Hotspur and tells him instead that battle is unavoidable. Hotspur, eager for glory, accepts.

The fighting at Shrewsbury is bloody and confused. The Scottish lord Douglas hunts the king across the field, killing Sir Walter Blunt, who is dressed as a decoy, and several other men disguised as Henry. Falstaff, supposed to be leading soldiers, has pocketed bribes and filled his ranks with ragged castoffs; on the field he plays dead to stay alive, musing that honor is just a word and survival is wiser. Hal, now every inch the warrior, saves his father from Douglas, then meets Hotspur at last. They fight, and Hal kills him, speaking a generous farewell over the body of the rival he once envied.

Then Falstaff rises from his fake death, stabs the dead Hotspur in the thigh, and claims the kill for himself. Hal, amused rather than angry, lets the old man have his lie. The battle ends in victory for King Henry. Worcester and Vernon, captured, are sentenced to death for hiding the king’s offer of peace and prolonging the bloodshed. Douglas is taken too, but Hal asks that he be freed without ransom, a gesture of mercy the king praises.

The war, however, is not over. Northumberland and the Archbishop of York are still in arms, and Glendower holds Wales. Henry splits his forces to chase them down, vowing to fight on until every rebel is crushed. Hal has proved himself a son worthy of the crown, but England remains divided, and the next round of rebellion is already waiting.
