Marozia

Marozia was born about 890. She was the daughter of the Roman consul Theophylact, Count of Tusculum, and of Theodora, the real power in Rome, whom Liutprand of Cremona characterized as a "shameless whore... [who] exercised power on the Roman citizenry like a man."

At the age of fifteen, Marozia became the mistress of Theophylact's cousin Pope Sergius III, whom she knew when he was bishop of Portus. The two had a son, John (the later Pope John XI). That, at least, is the story found in two contemporary sources, the Liber Pontificalis and the Antapodosis sive Res per Europam gestae (958–62), by Liutprand of Cremona (c. 920–72). But a third contemporary source, the annalist Flodoard (c. 894–966), says John XI was brother of Alberic II, the latter being the offspring of Marozia and her husband Alberic I. Hence John too may have been the son of Marozia and Alberic I.

Marozia married Alberic I, duke of Spoleto, in 909, and their son Alberic II was born in 911 or 912. By the time Alberic I was killed at Orte in 924, the Roman landowners had won complete victory over the traditional bureaucracy represented by the papal curia. Rome was virtually under secular control, the historic nadir of the papacy.

In order to counter the influence of Pope John X (whom the hostile chronicler Liutprand of Cremona alleges was another of her 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. The following popes, Leo VI and Stephen VII, were both her puppets. In 931 she even managed to impose her son as pontiff, under the name of John XI. John was only twenty-one at the time.

When her husband died in 929, Marozia negotiated a marriage with his half-brother Hugh of Arles, who had been elected King of Italy. Hugh was already married, but had that marriage annulled so that Hugh and Marozia could be wed. Alberic II, Marozia's son, led the opposition to the rule of Marozia and Hugh. After deposing them in 932, at the very wedding ceremonies, Alberic II imprisoned his mother until her death. Hugh escaped the city.

Marozia would remain in prison for some 5 years before she died. Alberic II was in his turn father of Octavian, who became Pope John XII in 955. Popes Benedict VIII, John XIX, Benedict IX, and antipope Benedict X of the House of Tusculani were also Marozia's descendants. By Guy of Tuscany she had a daughter named Berta Theodora, who never married.
