March 25 is both a national (revolution against the Turks) and religious holiday (Annunciation).
March 25 is the nameday for Vangelis or Evangelos and Vangelio or Evangelia or Eva.
The Byzantine Empire fell to the Turks in 1453 and the Greeks remained under the Ottoman rule for nearly 400 years. During this time their language, their religion and their sense of identity remained strong.
On March 25, 1821 the bishop Germanos of Patras raised the Greek flag at the Monastery of Agia Lavra in Peloponnese and one more revolution started against the Turks.
The people of Greece shouted “Freedom or Death” and they fought the War of Independence for 9 years (1821-1829) until a small part of modern Greece was finally liberated and it was declared an independent nation.
The struggle for the liberation of all the lands inhabited by Greeks continued. In 1864, the Ionian islands were added to Greece; in 1881 parts of Epirus and Thessaly. Crete, the islands of the Eastern Aegean and Macedonia were added in 1913 and Western Thrace in 1919. After World War II the Dodecanese islands were also returned to Greece.
