At just 15, Marozia had a wicked affair with Pope Sergius III, producing a son. Later, Marozia became mistress of another pope, John X, but she turned against him and married his enemy, Guy of Tuscany. In 928, they successfully carried out a coup d'etat in the Lateran Palace, the papal residence. Marozia had John X arrested, imprisoned and then strangled in the Castel Sant'Angelo, leaving her as de facto ruler of the city. The papacy and Rome sank to ever-greater depths of moral depravity. Marozia even raised her own bastard son to the throne of St Peter. But things began to fall apart for Marozia. Her other son, Alberic, invaded Rome, arrested John XI and imprisoned his mother in the Castel Sant'Angelo​. Marozia died in there, probably murdered by her own son. As for Alberic, he ruled Rome for 20 years with the majestic title Prince and Senator of all the Romans.
