Michael V Kalaphates

Michael V Kalaphates (c. 1015–1042), nicknamed for his father's trade as a caulker, was the nephew of Michael IV, adopted as son and heir by Empress Zoë and made caesar in 1035. He succeeded Michael IV in 1041 but soon banished his uncle John.

In 1042 he exiled Zoë to Principo. Constantinople rose in revolt; Zoë's sister Theodora was proclaimed empress and Michael fled to the Stoudion monastery. Dragged from sanctuary, he was blinded and confined to a monastery, where he died the same year after a four-month reign.
