Byzantine Empire /
(770-797) Byzantine emperor 780-797.
Constantine was considered a weak ruler, brought up by his mother, Irene, very much as an instrument for her own political ambitions. He showed little bravery in battles, stood his supporters up and enraged the popular opinion when he divorced his wife and married his mistress.
It was during his reign that icon veneration was reestablished, mainly from the pressure of his mother. Judging from his actions, it appears that he himself had iconoclast sympathies.
