Toto of Nepi.

About Toto of Nepi

Toto 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.
