What makes a man—or the public memory of a man—into a a legend? The Western world has always had legendary heroes, men who in life waged vigorous campaigns against terrifying odds, and who, in death, bear reputations burnished and embellished and gloriously expanded by the stories their admirers tell. Dietrich of Berne, Frederick Barbarossa, Alexander of Macedon, Charlemagne, the Cid, Russia’s Prince Igor, Cordoba’s Great Captain, and others, live on in legend centuries after their physical lives ended. The stories of these heroes are told in sagas, epics, and lays, in ballads and folksongs, romances and myths. There are also heroes more newly-made. Their stories are broadcast through the media of twentieth-century communication: popular biographies, historical fiction, diplomatic telegrams, reports of senatorial committees, newspaper accounts, magazine articles, motion pictures. Mexico provided the pre-eminent legendary hero of modern times: Pancho Villa.
