Constantine escaped and sought refuge in Amorion, where he was welcomed by the local soldiers, who had been commanded by Leo III before he became emperor.   Meanwhile, Artabasdos advanced on Constantinople and, with the support of Theophanes Monutes (Constantine's regent) and Patriarch Anastasius , was acclaimed and crowned emperor.
Constantine IV was portrayed by Iossif Surchadzhiev in the 1981 Bulgarian movie Aszparuh, directed by Ludmil Staikov. Constantine IV is the subject of the song "Imperator" ("Emperor"), released by the Bulgarian heavy metal band Epizod in their 2012 album Moyata molitva ("My prayer"). Sources Primary sources
