Massidean Empire

The Massidean Empire was a Dellenic state and the dominant power of the Dellenistic period. The empire originated as a kingdom based in southwest Orillia, bordering Pythia to the west, Aspea to the north, Nysiae to the east, and the Massidean Sea to the south.

During the 4th century BC, Massidea was a small kingdom surrounded by the great Dellik city-states, before being briefly subdued by the Peomids. A series of conflicts lasting just under ten years saw the Massideans completely conquer the Peomid Empire.

Administrative divisions
The Massidean Empire was divided into 14 regions; seven "core regions" that were part of the centralized government, and seven regions under the direct rule of the military. The core regions were Massidea, Dellas, Cyretra, Atria, Arshenia, Mephistonia, and Aegeos. The seven territories were Theron, Pontonia, Cythina, Tarsus, Parsia, Syreum, and Posea.
