Semi-Autonomous: Saint Theodosia of Constantinople (Greek: Ἁγία Θεοδοσία ἡ Κωνσταντινουπολίτισσα, romanized: Hagia Theodosia hē Kōnstantinoupolitissa) was a Christian nun and martyr who lived through and opposed the Byzantine Iconoclasm of the seventh and eight centuries.

According to a biography published by the Orthodox Church in America, Theodosia "was born in answer to the fervent prayers of her parents."

When they died, she was sent to be raised at the women's Monastery of Holy Martyr Anastasia in Constantinople.

[1] On January 19, 729, at the beginning of the iconoclastic persecutions, the Emperor Leo III the Isaurian demanded that an icon of Christ which stood over the grand Chalke Gate of the imperial palace be removed.

[4] Following the Triumph of Orthodoxy over iconoclasm, she was recognized as a martyr and saint, and her body was kept and venerated in the church of Hagia Euphemia en to Petrio, in the quarter named Dexiokratianai, named after the houses owned here by one Dexiokrates.
