Константин IV
Constantine IV was determined to solve the problem of the monotheletism/chalcedon controversy once and for all. Calling forth representatives from all corners of Christendom to discuss the matter at hand, they debated until in 681 when Constantine IV, who had presided over much of the meetings, endorsed the virtually unanimous findings. Four years later in 685, Constantine IV died. His death at thirty three years robbed Byzantium of a good Emperor who had defeated her enemies from within as well as without.
