Dorian invasion

The Dorian invasion is a concept devised by historians of Ancient Greece to explain the replacement of pre-classical dialects and traditions in southern Greece by the ones that prevailed in Classical Greece. The latter were named Dorian by the ancient Greek writers after the historical population that owned them, the Dorians.

Greek legend asserts that the Dorians took possession of the Peloponnesus in an event called the Return of the Heracleidae (Ancient Greek: Ἐπιστροφὴ τῶν Ἡρακλειδῶν). Classical scholars saw in the legend a possibly real event they termed the Dorian invasion. The meaning of the concept has changed several times, as historians, philologists and archaeologists used it in attempts to explain the cultural discontinuities expressed in the data of their fields. The pattern of arrival of Dorian culture on certain islands in the Mediterranean, such as Crete, is also not well understood. The Dorians colonised a number of sites on Crete such as Lato.

Despite nearly 200 years of investigation, the actuality of the Dorian invasion has never been established. The meaning of the concept has become to some degree amorphous. The work done on it has mainly served to rule out various speculations. The possibility of a real Dorian invasion remains open. Likewise, there have been attempts to link them or their victims with the emergence of the equally mysterious Sea Peoples.
