From Ottoman rule to the 1821 Greek revolt

The revolt followed roughly four centuries of Ottoman rule and several failed Greek uprisings. The Society of Friends supplied the organization, while educated middle-class supporters provided time, networks, and political coordination. Discovery forced the planned 1821 revolt to begin early, producing mixed results across the Danubian Principalities and the Peloponnese. The original ambition to seize Constantinople alarmed Britain and France because Russian protection of such a Greek state could have transformed control of the Dardanelles.
