For nearly 400 years, the Greeks were under the rule of the Ottoman Empire. March 25, 1821, is considered the official start of the revolution. On that day, Bishop Germanos of Patras raised the flag of revolution at Agia Lavra in the Peloponnese. This symbolic act marked the beginning of an armed uprising, although the war itself would last until 1829.

The day also has religious significance, as the church celebrates the Day of the Annunciation, when the Archangel Gabriel appeared to the Virgin Mary in Nazareth and announced that she would conceive the Son of God, Jesus Christ, through the Holy Spirit. The moment represents God's intervention in human history, signaling the beginning of the Incarnation of Christ.

For many Greeks, the day symbolizes both the historical struggle for freedom and the spiritual promise of hope.
