My Brothers Swore Revenge (1970)

Greece in the years of Turkish occupation. The Ottomans make frequent raids and seize Greek children, whom they lead to training camps and turn them into Janissaries. In such a mass kidnapping of children they seize a distinguished Greek boy and raise him according to the rules of this militantly anti-Christian group. Many years later, the Greek boy, now a man and an Ottoman conqueror, returns to his village and clashes with his own kin.
