Byzantine Iconoclasm
The Byzantine Iconoclasm (Ancient Greek: Εἰκονομαχία, romanized: Eikonomachía, lit. 'image struggle', 'war on icons') are two periods in the history of the Byzantine Empire when the use of religious images or icons was opposed by religious and imperial authorities within the Ecumenical Patriarchate (at the time still comprising the Roman-Latin and the Eastern-Orthodox traditions) and the temporal imperial hierarchy. The First Iconoclasm, as it is sometimes called, occurred between about 726 and 787, while the Second Iconoclasm occurred between 814 and 842.
