Marinus Sebastus (Italian : Marino Sebaste) was a scion of the dynasty of the Sergi (Dukes of Naples) and the Amalfitan family of the Capuano. He was a sebastos who was elected Duke of the Republic of Amalfi in 1096 in opposition to Norman suzerainty.
Bohemond of Taranto and Roger I of Sicily attacked Amalfi but were repulsed. It was at this siege that Bohemond met travelling warriors on the First Crusade and left to join them with an army. After his victory, Marinus strengthened the defences of the city and added 20,000 Saracen troops to the navy. He also created the ordo curialium, a court of justice, and recognised the autonomy and democracy of the citizenry.
Marinus was finally deposed by the Normans in alliance with certain Amalfitan noblemen sometime between 1100 and 1110.
Year 1098 (MXCVIII) was a common year starting on Friday of the Julian calendar.
Amalfi is a town and comune in the province of Salerno, in the region of Campania, Italy, on the Gulf of Salerno. It lies at the mouth of a deep ravine, at the foot of Monte Cerreto, surrounded by dramatic cliffs and coastal scenery. The town of Amalfi was the capital of the maritime republic known as the Duchy of Amalfi, an important trading power in the Mediterranean between 839 and around 1200.
Bohemond I was the Prince of Taranto from 1089 to 1111 and the Prince of Antioch from 1098 to 1111. He was a leader of the First Crusade, which was governed by a committee of nobles. The Norman monarchy he founded in Antioch arguably outlasted those of England and of Sicily.
The Treaty of Devol was an agreement made in 1108 between Bohemond I of Antioch and Byzantine Emperor Alexios I Komnenos, in the wake of the First Crusade. It is named after the Byzantine fortress of Devol. Although the treaty was not immediately enforced, it was intended to make the Principality of Antioch a vassal state of the Byzantine Empire.
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. During the 10th and 11th centuries Amalfi was estimated to have a population of 50,000–70,000 people. It rose to become an economic powerhouse, a commercial center whose merchants dominated Mediterranean and Italian trade in IX and X century, before being surpassed and superseded by the other maritime republics of the North, like Pisa, Venice, and Genoa. In 1073, Amalfi lost its independence, falling to Norman invasion and subsequently to Pisa in 1137.
Gisulf II was the last Lombard prince of Salerno (1052–1077).
Manso I was the duke of Amalfi (966–1004) and prince of Salerno (981–983). He was the son of Duke Sergius I and the greatest independent ruler of Amalfi, which he controlled for nearly half a century. He is sometimes numbered Manso III.
Sebastos was an honorific used by the ancient Greeks to render the Roman imperial title of Augustus. The female form of the title was sebastē (σεβαστή). From the late 11th century on, during the Komnenian period, it and variants derived from it, like sebastokrator, protosebastos, panhypersebastos, and sebastohypertatos, formed the basis of a new system of court titles for the Byzantine Empire.
Guy of Hauteville was an Italo-Norman soldier and diplomat who for a time served the Byzantine Empire.
Medieval Amalfi was ruled, in the tenth and eleventh centuries, by a series of dukes, sometimes called dogi, corresponding with the republic of Venice, a maritime rival throughout the Middle Ages. Before the title of Duke of Amalfi was formally established in 957, various patricians governed the territory. Amalfi established itself as one of the earliest maritime trading powers renowned throughout the Mediterranean, considered for two centuries, the most powerful of the maritime republics.
The Hauteville was a Norman family originally of seigneurial rank from the Cotentin. The Hautevilles rose to prominence through their part in the Norman conquest of southern Italy. By 1130, one of their members, Roger II, was made the first King of Sicily. His male-line descendants ruled Sicily until 1194. Some Italian Hautevilles took part in the First Crusade and the founding of the Principality of Antioch (1098).
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.
Maria was ruling Duchess of Amalfi in co-regency with her sons twice: in 1028–29 and in 1034–39. During the reigns of her sons, she appears to have held the actual power.
The Lombard Principality of Salerno was a South 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.
John III or John IV was the duke of Amalfi briefly in 1073 by right of succession following the death of his father, Sergius III, in November. John was only an infant when his father died, The Amalfitans, who required a ruler who could defend them, quickly deposed and exiled him. Consequently, given the lack of an adult ruler, Amalfi surrendered to the Normans led by Robert Guiscard.
The Norman conquest of southern Italy, also known as The Kingdom In The Sun, lasted from 999 to 1139, involving many battles and independent conquerors.
Manso was a Lombard viceduke (vicedux) who ruled the Duchy of Amalfi during the reign of Roger Borsa, the Norman Duke of Apulia. He is known only from his coins: large, copper follari bearing the inscription MANSO VICEDUX on the reverse. Irregular and poor in quality, mostly overstrikes of Salernitan coins, they were originally attributed to Manso of Salerno (981–83).
Roger, the son of Dagobert, was a Norman magnate who deserted to the Byzantine Empire where he entered the service of Emperor Alexios I Komnenos. He is the founder of the noble Byzantine family of Rogerios.
Alexios Komnenos was a Byzantine aristocrat and nephew of Emperor Alexios I Komnenos. Promoted to the rank of sebastos, he served as doux of Dyrrhachium from 1106 until after 1108. During this time, he led the successful resistance to a siege of Dyrrhachium by Bohemond I of Antioch, leading to the Treaty of Devol.
