This is a timeline of the presence of Orthodoxy in Greece. The history of Greece traditionally encompasses the study of the Greek people, the areas they ruled historically, as well as the territory now composing the modern state of Greece. The Greek War of Independence of 1821–28 created an independent southern Greece, but created anomalies in ecclesiastical relations since the Ecumenical Patriarch remained under Ottoman tutelage, and in 1850 the Endemousa Synod in Constantinople declared the Church of Greece autocephalous.
