The Peloponnese, with its long tradition of resistance to the Ottomans, was to become the heartland of the revolt. In the early months of 1821, with the absence of the Ottoman governor of the Morea (Mora valesi) Hursid Pasha and many of his troops, the situation was favourable for the Greeks to rise against Ottoman occupation.

The crucial meeting was held at Vostitsa (modern Aigion), where chieftains and prelates from all over the Peloponnese assembled on 26 January. There, Papaflessas, a pro-revolution priest who presented himself as representative of Filiki Eteria, clashed with most of the civil leaders and members of the senior clergy, such as Metropolitan Germanos of Patras, who were sceptical and demanded guarantees about a Russian intervention.
