Pope John X
In order to counter the influence of Pope John X (whom the hostile chronicler Liutprand of Cremona alleges was one of Marozia's lovers), Marozia subsequently married his opponent Guy of Tuscany, who loved his beautiful wife as much as he loved power. Together they attacked Rome, arrested Pope John X in the Lateran, and jailed him in the Castel Sant'Angelo. Either Guy had him smothered with a pillow in 928 or he simply died, perhaps from neglect or ill treatment. Marozia seized power in Rome in a "coup d'état". Guy died 3 February 929.
