Vatikiotis Konstantinos was the consul general of Greece in the Turkish-occupied Thessaloniki, who with remarkable courage and organizational ability began to incite the Greeks of Macedonia against the Turks. He distributed weapons to old, experienced warlords and fighters and created armed guerrilla corps, about 25 years before Lambros Koromilas, around 1878.
