Heracleidæ

This term means, in its widest sense, all the descendants of Heracles (Hercules), of whatever time, and in whatever district of Greece; but is specially applied to those adventurers who, founding their claims on their supposed descent from the great hero (to whom Zeus had promised a portion of the land), joined the Dorians in the conquest of the Peloponnesus. There were five different expeditions, the last and greatest occurring eighty years after the Trojan war. The story of the return of the Heracleidæ touches on the historical period, and though there is much of fable and tradition, yet there seems to be also a large substratum of truth in the records of the Greek historians.
