King Richard II is a historical play by William Shakespeare about the life and downfall of King Richard II of England. After acting as a judge between Henry Bolingbroke and Thomas Mowbray, the two decide to duel instead. King Richard banishes both of them before they can fight. Years later, after King Richard has become unpopular because of his expanding wealth, Henry sneaks back, overthrowing Richard (who is eventually imprisoned and killed) and becoming King.
Richard III is a tragic historical play following the rule and death of the title character, Richard. Conniving his way to power in the wake of his brother's death, Richard imprisons his nephews, marries the wife of a butchered enemy, and proceeds to live villainously. He acts out fantasies of revenge and spite bred from a long life of being looked down on due to his minor deformities. At the play's conclusion he is betrayed and killed in battle.
