==== Greece ====
* The [[Macedon]]ian regent, [[Antigonus III Doson|Antigonus III]], marries the former king [[Demetrius II of Macedon|Demetrius II's]] widow, Phthia, and assumes the crown thus deposing the young [[Philip V of Macedon|Philip V]].
* The [[Sparta]]n King [[Cleomenes III]] imposes reforms on his kingdom which include the cancelling of debts, providing land for 4,000 [[Citizenship|citizens]], and restoring the training of youth in the [[martial arts]]. The Ephorate, five elected magistrates who, with the King, form the main executive body of the state, is abolished (four of the five [[ephors]] being executed); the powers of the [[Gerousia]], the oligarchic council of elders, is curtailed; and the {{Transliteration|grc|patronomoi}} (the board of six elders) is introduced. Cleomenes' changes are designed to make the monarchy supreme and re-create a society of aristocrats, while neglecting Sparta's [[helots]] (serfs) and [[perioikoi]] (free but non-citizen inhabitants). Eighty opponents of the reforms are exiled, while his brother [[Eucleidas]] is installed as co-ruler in the place of the murdered [[Archidamus V]].
* Cleomenes III defeats the [[Achaean League|Achaeans]] under [[Aratus of Sicyon]] at Mount Lycaeum and at Ladoceia near [[Megalopolis, Greece|Megalopolis]].
