The Anastenaria (Greek: Αναστενάρια, Bulgarian: Нестинарство, romanized: Nestinarstvo), is a traditional barefoot fire-walking ritual with ecstatic dance performed in some villages in Northern Greece and Southern Bulgaria. The communities which celebrate this ritual are descended from refugees who entered Greece from Eastern Thrace following the Balkan Wars of 1911–12 and the Population exchange between Greece and Turkey in 1923.
