The Byzantine Emperor Stripped of Power by His Mother
In the eighth century, theological debates about Christian doctrine often sparked violent reactions from ordinary Christians. One such debate was over the use of religious images, or icons. Some Christians believed that the worship of icons was a violation of the Second Commandment and therefore equivalent to idol worship. This belief, combined with the Muslim conquest of the Middle East and Africa, led to a backlash against icons known as Iconoclasm. Emperors Leo III and Constantine V enforced Iconoclasm, but it was eventually undone by Irene of Athens, who called a church council in 786 to denounce the policy.
When her son Constantine VI became an Iconoclast, Irene had him overthrown and mutilated, and she continued her mission to reintroduce religious imagery until she was exiled and died in 803. Irene then proclaimed herself empress. She continued her quest to undo Iconoclasm and reintroduce religious imagery, until she fell from power in 802 in the aftermath of a revolt. She was exiled to the Isle of Lesbos, and died there a year later. In conclusion, the Byzantine Empire in the eighth century was rife with religious turmoil, with debates over Christian doctrine leading to violence and political upheaval.
