Richard III is dominated by Richard the hunchback Duke of Gloucester, who becomes Richard III through a series of horrible acts, killing off his enemies, his kinsmen, his wife and most of his supporters before reaching the Battle of Bosworth and crying out "My kingdom for a horse." Julius Caesar is a dramatization of actual events, Shakespeare drawing upon the ancient Roman historian Plutarch's Lives of Caesar, Brutus, and Mark Antony. It establishes the dramatic problem of alarm at Julius Caesar's ambition to become "king" (or dictator) in the very first scene and introduces signs that Caesar must "beware the Ides of March" from the outset. Before its midpoint, Caesar is assassinated, and shortly after Mark Antony's famous funeral oration ("Friends, Romans, and countrymen … "), the setting shifts permanently from Rome to the battlefields on which Brutus and Cassius meet their inevitable defeat. The Tempest combines elements of tragedy (Prospero's revenge) with those of romantic comedy (the young lovers Miranda and Ferdinand), and poses deeper questions that are not completely resolved at the end regarding little things like the nature of existence and the enigma of the human condition.
