Description

Constantine V (Greek: Κωνσταντῖνος Ε΄; denigrated by his enemies as Kopronymos or Copronymus, meaning the dung-named) was Byzantine Emperor from 741 to 775.

Constantine V ruled as sole Emperor until he crowned his son Leo IV ("the Khazar") as co-emperor in 751, when Leo was still an infant. In 775 Constantine V died, leaving Leo as sole emperor.
