The spreading of this pagan custom in South- east, North- west and west Bulgaria is a result of late migrations (XVIII- XIX c. AC). Nowadays the “Koukers’ games are equally distributed in: Greece (North from Olymp and Thesalia), Macedonian, Turkey (the  suburbs of Istanbul), Bulgaria (Black Sea coastline, Thracia, Sredna gora, the upper part of the river Struma, South Dobrudza), Romania (North Dobrudza), Besarabia. According to the scientists all these people are temporarily inhabiting the Balkan Peninsula and the Danube- Carpatian district. They all have custom coinciding in origin and content with the “Koukers’ games”. The Bulgarian have “Koukeri”, “Dzamali”, “Startsi”; the Greeks- “Kalogeri” and “Kudunades”; the Romanians- “Tuka”, “Brezaia” and “Plugushorul”; the Serbs- “Mashkare”, “Klotsalitsa”, “Turitsa” and “Dedove”. All these rituals have one and same old Greek  origin.
