Pope Stephen III
Toto (died 29 July 768) was the self-styled duke of Nepi, the leading magnate of Etruria, who staged a "coup d'état" in Rome in 767. He became Duke of Rome for a year until his death. The principal sources documenting his takeover are the "vita" of Pope Stephen III in the "Liber Pontificalis" and a surviving deposition of the "primicerius" Christopher from 769, preserved in a ninth-century manuscript of Verona, the "Depositio Christophori".
