A synedrion or synhedrion (Greek: συνέδριον, "sitting together", hence "assembly" or "council"; , sanhedrin) is an assembly that holds formal sessions. The Latinized form is synedrium. Depending on the widely varied constitutions, it applied to diverse representative or judiciary organs of Greek and Hellenistic city-states and treaty organisations. Synedrions in Greek states Macedonia The supreme body of Alexander the Great's empire was also called "Synedrion". The Council was a small group formed among some of the most eminent Macedonians, chosen by the king to assist him in the government of the kingdom. As such it was not a representative assembly, but notwithstanding that, on certain occasions, it could be expanded with the admission of representatives of the cities and of the civic corps of the kingdom. The Council primarily exerted a probouleutic function with respect to the Assembly: it prepared and proposed the decisions which the Assembly would have discussed and voted, working in many fields such as the designation of kings and regents, as of that of the high administrators and the declarations of war. It was also the first and the last authority for all the cases which did not involve capital punishment. Inside the Council ruled the democratic principles of isegoria (equality of word) and of parrhesia (freedom of speech), to which the king subjects himself like the other members. After the removal of the Antigonid dynasty by the Romans in 167 BC, it is possible that the synedrion remained, unlike the Assembly, representing the sole federal authority in Macedonia after the kingdom's division into four merides . Synedrion at Corinth The League of Corinth was a federation of Greek states created by king Philip II of Macedon during the winter of 338/337 BC to facilitate his use of Greek military forces in his war against Achaemenid Persia. The league guaranteed, among other things, that member states' constitutions in force at the time of joining were guaranteed and that a Synedrion, or congress of representatives, was to meet at Corinth. Synedrion at Epirus In the 3rd century BC Epirus remained a substantial power, unified under the auspices of the Epirote League as a federal state with its own parliament (or synedrion). However, it was faced with the growing threat of the expansionist Roman Republic, which fought a series of wars with Macedonia. The League remained neutral in the first two Macedonian Wars but split in the Third
