The convention sanctioned by Alexander was probably the same as that settled by and with his father Philip. Its grand and significant feature was, that it recognized Hellas as a confederacy under the Macedonian prince as imperator, president, or executive head and arm. It crowned him with a legal sanction as keeper of the peace within Greece, and conqueror abroad in the name of Greece. Of its other conditions, some are made known to us by subsequent complaints; such conditions as, being equitable and tutelary towards the members generally, the Macedonian chief found it inconvenient to observe, and speedily began to violate. Each Hellenic city was pronounced, by the first article of the convention, to be free and autonomous. In each, the existing political constitution was recognized as it stood; all other cities were forbidden to interfere with it, or to second any attack by its hostile exiles.[32] No new despot was to be established; no dispossessed despot was to be restored.[33] Each city became bound to discourage in every other, as far as possible, all illegal violence—such as political executions, confiscation, spoliation, redivision of land or abolition of debts, factious manumission of slaves, etc.[34] To each was guaranteed freedom of navigation; maritime capture was prohibited, on pain of enmity from all.[35] Each was forbidden to send armed vessels into the harbor of any other, or to build vessels or engage seamen there.[36] By each, an oath was taken to observe these conditions, to declare war against all who violated them, and to keep them inscribed on a commemorative column. Provision seems to have been made for admitting any additional city[37] on its subsequent application, though it might not have been a party to the original contract. Moreover, it appears that a standing military force, under Macedonian orders, was provided to enforce observance of the convention; and that the synod of deputies was contemplated as likely to meet periodically.[38] [32] Demosthenes (or Pseudo-Demosthenes), Orat. xvii.
