Leo III the Isaurian

685 CE741 CE · Constantinople

Leo III, often called the Isaurian, was Byzantine emperor from 717 to 741 and founder of the Isaurian dynasty. Soon after taking the throne he directed the successful defense of Constantinople against a massive Arab siege in 717–718, a victory that checked the westward advance of the caliphate. He reorganized the empire's finances and law, issuing the legal handbook known as the Ecloga. He is best known for initiating the policy of iconoclasm around 726, ordering the removal of religious images, a decision that opened a long and divisive controversy within the church.
