John the Rhaiktor

John the Rhaiktor (Greek: Ἰωάννης ὁ ῥαίκτωρ; fl. 922–947) was a Byzantine official, who served as the chief minister (paradynasteuon) of the empire in the early reign of Romanos I Lekapenos. Facing accusations, he left his office and retired to a monastery, but remained a confidant of the emperor, for whom he undertook a delicate diplomatic mission to Bulgaria in 929. He is likely to be identified as one of the conspirators who in 947 intended to depose Constantine VII and restore Romanos I's son Stephen Lekapenos to the throne.
