Year 849 (DCCCXLIX) was a common year starting on Tuesday of the Julian calendar.
Pope Leo IV was the bishop of Rome and ruler of the Papal States from 10 April 847 to his death. He is remembered for repairing Roman churches that had been damaged during the Arab raid against Rome, and for building the Leonine Wall around Vatican Hill to protect the city. Pope Leo organized a league of Italian cities who fought and won the sea Battle of Ostia against the Saracens.
Saracen was a term used both in Greek and Latin writings between the 5th and 15th centuries to refer to the people who lived in and near what was designated by the Romans as Arabia Petraea and Arabia Deserta. The term's meaning evolved during its history of usage. During the Early Middle Ages, the term came to be associated with the tribes of Arabia.
Sorrento is a town overlooking the Bay of Naples in Southern Italy. A popular tourist destination, Sorrento is located on the Sorrentine Peninsula at the south-eastern terminus of the Circumvesuviana rail line, within easy access from Naples and Pompei. The town is widely known for its small ceramics, lacework and marquetry (woodwork) shops.
The Italian city-states were numerous political and independent territorial entities that existed in the Italian Peninsula from antiquity to the formation of the Kingdom of Italy in the late 19th century.
Gaeta is a city in the province of Latina, in Lazio, Southern Italy. Set on a promontory stretching towards the Gulf of Gaeta, it is 120 kilometres from Rome and 80 km (50 mi) from Naples.
The history of Italy in the Middle Ages can be roughly defined as the time between the collapse of the Western Roman Empire and the Italian Renaissance. Late Antiquity in Italy lingered on into the 7th century under the Ostrogothic Kingdom and the Byzantine Empire under the Justinian dynasty, the Byzantine Papacy until the mid 8th century. The "Middle Ages" proper begin as the Byzantine Empire was weakening under the pressure of the Muslim conquests, and most of the Exarchate of Ravenna finally fell under Lombard rule in 751. From this period, former states that were part of the Exarchate and were not conquered by the Lombard Kingdom, such as the Duchy of Naples, became de facto independent states, having less and less interference from the Eastern Roman Empire.
The Duchy of Benevento was the southernmost Lombard duchy in the Italian Peninsula that was centred on Benevento, a city in Southern Italy. Lombard dukes ruled Benevento from 571 to 1077, when it was conquered by the Normans for four years before it was given to the Pope. Being cut off from the rest of the Lombard possessions by the papal Duchy of Rome, Benevento was practically independent from the start. Only during the reigns of Grimoald and the kings from Liutprand on was the duchy closely tied to the Kingdom of the Lombards. After the fall of the kingdom in 774, the duchy became the sole Lombard territory which continued to exist as a rump state, maintaining its de facto independence for nearly 300 years, although it was divided after 849. Benevento dwindled in size in the early 11th century, and was completely captured by the Norman Robert Guiscard in 1053.
The naval Battle of Ostia took place in 849 in the Tyrrhenian Sea between a Muslim fleet and an Italian league of Papal, Neapolitan, Amalfitan, and Gaetan ships. The battle ended in favor of the Italian league, as they defeated the Muslims. It is one of the few events to occur in southern Italy during the ninth century that is still commemorated today, largely through the walls named after Leo and for the Renaissance painting Battaglia di Ostia by Raphael.
The Duchy of Gaeta was an early medieval state centered on the coastal South Italian city of Gaeta. It began in the early ninth century as the local community began to grow autonomous as Byzantine power lagged in the Mediterranean and the peninsula due to Lombard and Saracen incursions.
The Duchy of Amalfi or the Republic of Amalfi was a de facto independent state centered on the Southern Italian city of Amalfi during the 10th and 11th centuries. The city and its territory were originally part of the larger ducatus Neapolitanus, governed by a patrician, but it extracted itself from Byzantine vassalage and first elected a duke in 958.
The Duchy of Naples began as a Byzantine province that was constituted in the seventh century, in the reduced coastal lands that the Lombards had not conquered during their invasion of Italy in the sixth century. It was governed by a military commander (dux), and rapidly became a de facto independent state, lasting more than five centuries during the Early and High Middle Ages. Naples remains a significant metropolitan city in present-day Italy.
The Donation of Sutri was an agreement reached at Sutri by Liutprand, King of the Lombards and Pope Gregory II in 728. At Sutri, the two reached an agreement by which the city and some hill towns in Latium were given to the Papacy, "as a gift to the blessed Apostles Peter and Paul" according to the Liber Pontificalis. The pact formed the first extension of papal territory beyond the confines of the Duchy of Rome and was the first of two land transfers from Liutprand to the Church of Rome.
The Arab raid against Rome took place in 846. Muslim raiders plundered the outskirts of the city of Rome, sacking the basilicas of Old St Peter's and St Paul's-Outside-the-Walls, but were prevented from entering the city itself by the Aurelian Walls.
Sergius I was the first duke of Naples of his dynasty, often dubbed the "Sergi," which ruled over Naples for almost three centuries from his accession in 840 until the death of his namesake Sergius VII in 1137.
The Principality of Salerno was a medieval Southern Italian state, formed in 851 out of the Principality of Benevento after a decade-long civil war. It was centred on the port city of Salerno. Although it owed allegiance at its foundation to the Carolingian emperor, it was de facto independent throughout its history and alternated its allegiance between the Carolingians and their successors in the West and the Byzantine emperors in the east.
The maritime republics, also called merchant republics, were Italian thalassocratic port cities which, starting from the Middle Ages, enjoyed political autonomy and economic prosperity brought about by their maritime activities. The term, coined during the 19th century, generally refers to four Italian cities, whose coats of arms have been shown since 1947 on the flags of the Italian Navy and the Italian Merchant Navy: Amalfi, Genoa, Pisa, and Venice. In addition to the four best known cities, Ancona, Gaeta, Noli, and, in Dalmatia, Ragusa, are also considered maritime republics; in certain historical periods, they had no secondary importance compared to some of the better known cities.
The history of Islam in Sicily and southern Italy began with the first Arab settlement in Sicily, at Mazara, which was captured in 827. The subsequent rule of Sicily and Malta started in the 10th century. The Emirate of Sicily lasted from 831 until 1061, and controlled the whole island by 902. Though Sicily was the primary Muslim stronghold in Italy, some temporary footholds, the most substantial of which was the port city of Bari, were established on the mainland peninsula, especially in mainland southern Italy, though Muslim raids, mainly those of Muhammad I ibn al-Aghlab, reached as far north as Naples, Rome and the northern region of Piedmont. The Arab raids were part of a larger struggle for power in Italy and Europe, with Christian Byzantine, Frankish, Norman and local Italian forces also competing for control. Arabs were sometimes sought as allies by various Christian factions against other factions.
The Norman conquest of southern Italy lasted from 999 to 1194, involving many battles and independent conquerors.
Byzantine Italy was those parts of the Italian peninsula under the control of the Byzantine empire after the fall of the Western Roman Empire (476). The last Byzantine outpost in Italy, Bari was lost in 1071. Chronologically, it refers to:
