This paper seeks to stress that Marlowe's Edward II is, at bottom, a tragic story or a personal history of its hero's agonies. Therefore, it starts by considering the dramatic genre of the chronicle play, and shows that studying Edward II as a traditional history play does not penetrate into its design and operation. Then the paper moves to emphasize that Mortimer's rebellion and punishment fit didactic history drama. This leads us to explore Edward's continual endeavors to write his agonies in the form of a tale or tragedy.
