Roger II or Roger the Great was King of Sicily and Africa, son of Roger I of Sicily and successor to his brother Simon. He began his rule as Count of Sicily in 1105, became Duke of Apulia and Calabria in 1127, then King of Sicily in 1130 and King of Africa in 1148.
Gaeta is a city in the province of Latina, in Lazio, 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 history of Naples is long and varied, dating to Greek settlements established in the Naples area in the 2nd millennium BC. During the end of the Greek Dark Ages a larger mainland colony – initially known as Parthenope – developed on the Pizzofalcone hill in the 8th century BC, and was refounded as Neapolis in the 6th century BC: it held an important role in Magna Graecia. The Greek culture of Naples was important to later Roman society. When the city became part of the Roman Republic in the central province of the Empire, it was a major cultural centre.
Guaimar IV was Prince of Salerno (1027–1052), Duke of Amalfi (1039–1052), Duke of Gaeta (1040–1041), and Prince of Capua (1038–1047) in Southern Italy over the period from 1027 to 1052. He was an important figure in the final phase of Byzantine authority in the Mezzogiorno and the commencement of Norman power. He was, according to Amatus of Montecassino, "more courageous than his father, more generous and more courteous; indeed he possessed all the qualities a layman should have—except that he took an excessive delight in women."
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.
Sergius IV was Duke of Naples from 1002 to 1036. He was one of the prime catalysts in the growth of Norman power in the Mezzogiorno in the first half of the eleventh century. He was nominally a Byzantine vassal, like his father, John IV, before him.
The dukes of Naples were the military commanders of the ducatus Neapolitanus, a Byzantine outpost in Italy, one of the few remaining after the conquest of the Lombards. In 661, Emperor Constans II, highly interested in south Italian affairs, appointed a Neapolitan named Basil dux or magister militum. Thereafter a line of dukes, often largely independent and dynastic from the mid-ninth century, ruled until the coming of the Normans, a new menace they could not weather. The thirty-ninth and last duke, Sergius VII, surrendered his city to King Roger II of Sicily in 1137.
John IV was the mostly absentee duke of Naples from 997 to after 1002. He was the son and successor of Sergius III. John IV originally recognised the suzerainty of the Byzantine Emperor.
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.
John II was the duke of Amalfi from 1029 to 1069 with multiple interruptions. He was the son of Sergius II and Maria, sister of Pandulf IV of Capua. He was the last significant duke of Amalfi before the Norman conquest of 1073.
The Drengots were a Norman family of mercenaries, one of the first to head to Southern Italy to fight in the service of the Lombards. They became the most prominent family after the Hautevilles.
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 Principality of Capua was a Lombard state centred on Capua in Southern Italy. Towards the end of the 10th century the Principality reached its apogee, occupying most of the Terra di Lavoro area. It was originally a gastaldate, then a county, within the principality of Salerno.
Caesar the Brave was the admiral of the fleet of the Duchy of Naples during the reigns of his father, Sergius I, and brother, Gregory III.
Sergius VI was the magister militum and duke of Naples from 1077 to his death. He was the son of the Neapolitan senator John, and succeeded his uncle, John's elder brother, Sergius V. His sister Inmilgia married Duke Landulf of Gaeta. His reign is very obscure because of the slight documentary evidence.
The Norman conquest of southern Italy lasted from 999 to 1194, involving many battles and independent conquerors.
