Adhemar [1] was the Duke of Spoleto from 998 and Prince of Capua from 1000. Before his death, he lost both domains. He is not mentioned as duke of Spoleto after December 999.
He was the son of Balsamo, a Capuan cleric. He was educated at the court of Otto II, alongside the future emperor Otto III.
In order to break the power of Hugh the Great, margrave of Tuscany, who had become duke of Spoleto, Otto III appointed one Conrad as duke in May 996. In December 998, Otto appointed his childhood companion Adhemar as duke. Otto then took him south and they marched on Capua, where Laidulf, the reigning prince, was removed from his position for the assassination of his brother. They then marched on Naples and took Duke John IV captive to Capua. Laidulf, along with his wife Maria and Gaideris and Lando of Caiazzo, were exiled from the city and Adhemar was left in charge. John of Naples was taken back by Otto to Germany. In 1000, Adhemar was named prince and entered Capua on 11 March. By July he was removed by the Capuans, who elected Landulf of Sant'Agata instead. As prince, however, he did create Atenulf as count of Aquino, thus inaugurating that dynasty.
The Duchy of Spoleto was a Lombard territory founded about 570 in central Italy by the Lombard dux Faroald. Its capital was the city of Spoleto.
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.
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. From 1041 to 1052 the Duke of Napoli was his vassal. 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."
Pandulf I Ironhead was the Prince of Benevento and Capua from 943 until his death. He was made Duke of Spoleto and Camerino in 967 and succeeded as Prince of Salerno in 977 or 978. He was an important nobleman in the fight with the Byzantines and Saracens for control of the Mezzogiorno in the centuries after the collapse of Lombard and Carolingian authority on the Italian Peninsula. He established himself over almost the whole of the southern half of Italia before his death in March 981.
The Duke of Spoleto was the ruler of Spoleto and most of central Italy outside the Papal States during the Early and High Middle Ages. The first dukes were appointed by the Lombard king, but they were independent in practice. The Carolingian conquerors of the Lombards continued to appoint dukes, as did their successors the Holy Roman Emperors. In the 12th century, the dukes of Spoleto were the most important imperial vassals in Italy.
Jordan I, count of Aversa and prince of Capua from 1078 to his death, was the eldest son and successor of Prince Richard I of Capua and Fressenda, a daughter of Tancred of Hauteville and his second wife, also named Fressenda, and the nephew of Robert Guiscard, duke of Apulia, Calabria, and Sicily. He, according to William of Apulia, "equalled in his virtues both the duke and his father."
Gisulf II was the last Lombard prince of Salerno (1052–1077).
Alfonso, also called Anfuso or Anfusus (c. 1120 – 10 October 1144), was the Prince of Capua from 1135 and Duke of Naples from 1139. He was an Italian-born Norman of the noble Hauteville family. After 1130, when his father Roger became King of Sicily, he was the third in line to the throne; second in line after the death of an older brother in 1138. He was the first Hauteville prince of Capua after his father conquered the principality from the rival Norman Drengot family. He was also the first Norman duke of Naples after the duchy fell vacant on the death of the last Greek duke. He also expanded his family's power northwards, claiming lands also claimed by the Papacy, although he was technically a vassal of the Pope for his principality of Capua.
Pandulf II the Old was the prince of Benevento from 981 and prince of Capua from 1008 or 1009 to his death, and was the son of Landulf III who was co-prince between 959 and 968. Pandulf was first associated as co-prince in 977.
Laidulf was a son, probably the youngest or second youngest, of Pandulf Ironhead. He probably never expected to inherit much, especially with his many cousins vying for their rightful inheritances. He was the Count of Teano, and was implicated in the assassination of his brother, Landenulf, and the archbishop of Benevento in 993.
Lando I was the count of Capua from 843. He was the eldest son and successor of Landulf the Old. Like his father, he supported Siconulf against Radelchis in the civil war dividing the Principality of Benevento in the 840s.
Lando III was the count of Capua for two years and ten months from 882 to his death. He was a son of Landenulf, gastald of Teano, and grandson of Landulf I of Capua.
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.
Hugh, called the Great, was the Margrave of Tuscany from 969 until his death in 1001, and the Duke of Spoleto and Margrave of Camerino from 989 to 996. He was known for his restoration of the state apparatus in Tuscany after decades of neglect from various Margraves, whose main interests lay elsewhere. Hugh was also noted for his support of the new Ottonian dynasty, and has been praised for his justice by the contemporary theologian Peter Damian in his De principis officio. Hugh's rule has also been remembered for its close cooperation with the Papal States in the resolution of territorial disputes and his generosity in gifting marchesal (public) lands for the foundation of monasteries of the Catholic Church.
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.
Pandenulf was the Count of Capua, claiming that title from 862 and holding it successfully during the tumultuous civil war of 879 – 882. He was the son and successor of Pando, but was removed on his father's death by his uncle the bishop, Landulf II.
