Antigonus I Monophthalmus
In 307/306 – 224/223 BC the system was reorganized with the creation of two Macedonian Phylai (XI. Antigonis and XII. Demetrias), named after Demetrius I of Macedon and Antigonus I Monophthalmus, and an increase in the membership of the Boule to 600. Each of the ten tribes, except Aiantis, provided three demes (not necessarily one for trittyes); the missing contribution of Aiantis was covered by two demes of Leontis and one from Aigeis.
