Koinon means "Common", it could be attributed with commonwealth, commune or collective but these terms have associated connotations because of already established usage.

The Zagorisians would not pay taxes to the Ottomans but an obligation was agreed upon to maintain a number of attendants to the Sultan's stables.

These included the replacement of the obligation to send attendants to the Sultan's stables with a tax, the free exercise of the Christian faith and significantly a prohibition of entry of Turks into Zagori.

From 1750, the Vekylis of Zagori took up residence in Ioannina, in a House of the Koinon of the Zagorisians or in private.

During the Ottoman period Zagori was one of three Greek regions that enjoyed autonomy under a treaty, the other two were Mani in the Peloponnese and Mademochoria in Macedonia.
