Mittleres Reich
The Middle Helladic period corresponds in time to the Middle Kingdom of Egypt. Settlements draw more closely together and tend to be sited on hilltops. Middle Helladic sites are located throughout the Peloponnese and central Greece (including sites in the interior of Aetolia such as Thermon) as far north as the Spercheios River valley. Malthi in Messenia and Lerna V are the only Middle Helladic sites to have been thoroughly excavated.
