This is a timeline of the presence of Eastern Orthodoxy in Greece from 1821 to 1924. 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.

Greek War of Independence (1821–1829)

1821 Greek War of Independence begins as Metr. Germanos of Patras declares Greek independence on Day of Annunciation (25 March), also Kyrio-Pascha,Hieromonk Cassian. A Scientific Examination of the Orthodox Church Calendar - Ch. 9: Liturgical Havoc Wreaked by the "New Julian" Calendar. Eds. Archbishop Chrysostomos and Hieromonk Gregory. Etna, CA: Center for Traditionalist Orthodox Studies, 1998. Retrieved: 12 July 2013.From antiquity the Orthodox Church has celebrated with special liturgical joy the occurrence when Pascha falls on 25 March (Old Style) - the Feast of the Annunciation, calling it "Kyriopascha," "the Lord's Pascha". It was precisely on the coincidence of the Feasts of the Annunciation and Pascha on 25 March 1821 (Old Style), that Greece challenged the Turkish Yoke. Kyriopascha has also manifested its miraculous Grace to our own generation by its most recent occurrence in 1991, the year of the demise of Communism in Russia, a demise which, furthermore, was finalized by a last, desperate gasp in the form of an abortive Communist coup thwarted on 6 August (Old Style)–the Feast of the Transfiguration. The last Kyriopascha on the Julian calendar was in 1991; the next will be in 2075, 2086 and 2159. The last Kyriopascha on the Gregorian Calendar was in 1951, and the next will be in 2035, 2046 and 2103. at the Monastery of Agia Lavra, Peloponnese; martyrdom of Patr.
