9th Century AD – The Saracens Take Sicily
The 9th century AD belonged to the invaders. In 827 the Aghlabid Saracens of Tunisia landed at Mazara, and over the following decades they took Sicily piece by piece — Palermo in 831, Messina in 842, Enna in 859 after a thirty-year siege, and finally Syracuse in 878, its great cathedral converted into a mosque. On the mainland, a Saracen emirate held Bari for a quarter century, raiders sacked the basilicas of St. Peter and St. Paul outside Rome, and the monastery of Monte Cassino was destroyed. Meanwhile the Carolingian empire of Charlemagne’s heirs divided, reunited, and dissolved into civil war, and the Lombard south splintered — Benevento against Salerno, Capua against Naples, with Christian dukes hiring Saracen mercenaries against their Christian neighbors. Out of the wreckage came new powers: the Sergi dynasty of Naples, the seafaring republics of Amalfi and Gaeta, and a resurgent Byzantium that retook Bari and rebuilt its rule over Apulia and Calabria.

- Before this can be accomplished, Euphemius rises in revolt, kills the strategos, seizes Syracuse, and declares himself Emperor. A strong fleet dispatched from Constantinople soon defeats him.
- Eluding capture, Euphemius escapes to Tunisia and takes refuge with the Saracen Aghlabid Emir Ziyadat Allah. He convinces the Emir that Sicily can be conquered, promising a large annual tribute if Ziyadat Allah sets him up as Emperor there. The Emir agrees to mount a large expedition — with the secret intention of conquering the island for himself.
- Ziyadat Allah declares a holy war against the Byzantines and places his forces under the command of the 70-year-old lawyer and holy man Ased-ibn-Forat (Furat), who rallies an Islamic army of Arabs, Berbers, Moors, Spanish Saracens, and even Persians.

- Euphemius accompanies the Saracens believing the Sicilians will rally to him. Most reject him as a traitor and criminal.
- (July 15) Photinus, the Byzantine strategos, attacks the invaders near Platana but suffers a major defeat, losing most of his army. He escapes to Enna and eventually to Calabria, dying soon afterwards. The Saracen victory is attributed largely to the religious fervor Ased-ibn-Forat stirred in his followers — a story, probably apocryphal, claims Forat led the charge himself and slew so many enemies that his hand became glued to his lance by their dried blood.
- Saracens capture Agrigentum and rename it Kerkent (or 828), then continue east toward Syracuse.

Key Themes of the 9th Century
- The Saracen Conquest of Sicily
- From the landing at Mazara (827) through Palermo (831), Messina (842), Enna (859), Syracuse (878), and Taormina (879), the Aghlabids reduced Byzantine Sicily to a handful of holdouts.
- The conquest began with a Byzantine traitor — the rebel Euphemius — who invited the invaders in.
- Saracens on the Mainland
- A Berber emirate held Bari from 847 to 871. Raiders sacked the basilicas of St. Peter and St. Paul outside Rome (846), destroyed old Capua (841) and Monte Cassino (883), and razed Paestum (887).
- The Battle of Ostia (849) and the new Leonine walls around the Vatican (848) were the papacy’s answer.
- Christians Hiring Saracens
- Duke Andrew II of Naples became the first Italian prince to hire Saracen mercenaries (836). Naples, Benevento, and Gaeta all followed the practice against fellow Christians, drawing repeated papal excommunications.
- The Carolingian Collapse
- Charlemagne’s death (814) began a century of division: the Treaty of Verdun (843), Louis II’s lonely campaigns in the south, and after 875 a revolving door of emperors and kings of Italy ending in open civil war between Guy of Spoleto, Lambert, Berengar, and Arnulf.
- The Fragmenting South
- Benevento and Salerno split into rival principalities (840–849); Capua rose under its own counts; the Sergi dynasty took Naples (840); Amalfi and Gaeta emerged as independent maritime powers.
- The Byzantine Recovery
- Even as Sicily was lost, Byzantium retook Bari (876), created the thema of Langobardia (874), and installed a Catapan of Apulia (885) — rebuilding imperial rule over the southern mainland that would last into the 11th century.
By 900 AD, Sicily was an emirate, the Carolingian order was dead, and southern Italy had settled into the crowded chessboard — Lombard princes, Byzantine governors, maritime dukes, and Saracen raiders — that would define the next two centuries. The 10th century opens with Capua and Benevento united under Atenulf I and with new invaders, the Magyars, already probing Italy from the north.
