Byzantine Iconoclasm
Leo V the Armenian (, "Leōn ho ex Armenias"; 755 – 25 December 820) was Emperor of the Byzantine Empire from 813 to 820. A senior general, he forced his predecessor, Michael I Rangabe, to abdicate and assumed the throne. He ended the decade-long war with the Bulgars, and initiated the second period of Byzantine Iconoclasm. He was assassinated by supporters of Michael the Amorian, one of his most trusted generals, who succeeded him on the throne.
