You’re St. Theodora!
Theodora was the wife of the ninth-century emperor Theophilus and mother of the future emperor Michael III. Theodora ruled the lands after her iconoclastic husband died. She labored to overturn his heretical policies, chiefly by summoning a council that upheld the veneration of images of Christ and the saints. For this, she is herself honored as a saint by the Orthodox Church. Her feast day is February 11.
