Prince Harry’s troubled relationship with his father, King Henry IV, drives the plot of one of Shakespeare’s most engrossing political plays. Harry doesn’t want to comport himself as royalty; he would prefer to cavort in low-class taverns with the likes of Falstaff, his hard-drinking, nap-loving substitute father. Meanwhile, the disgruntled noblemen in the Percy family are staging a rebellion against the kingdom.
