Pope John XII, born Octavian, was the bishop of Rome and ruler of the Papal States from 16 December 955 to his death in 964. He was related to the counts of Tusculum, a powerful Roman family which had dominated papal politics for over half a century. He became pope in his late teenage years or early twenties. In 960, he clashed with the Lombards to the south. Unable to control Rome easily, he sought help from King Otto I of Germany and crowned him emperor. John XII's pontificate became infamous for the alleged depravity and worldliness with which he conducted his office. He soon fell out with Otto, but died before Otto succeeded in his attempt to depose him.
Pope John X was the bishop of Rome and nominal ruler of the Papal States from March 914 to his death. A candidate of the counts of Tusculum, he attempted to unify Italy under the leadership of Berengar of Friuli, and was instrumental in the defeat of the Saracens at the Battle of Garigliano. He eventually fell out with Marozia, who had him deposed, imprisoned, and finally murdered. John’s pontificate occurred during the period known as the Saeculum obscurum.
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 to continue to exist as a rump state, maintaining its de facto independence for nearly 300 years, although it was divided after 849.
Theophylact I was a medieval count of Tusculum who was the effective ruler of Rome from around 905 through to his death in 924. His descendants controlled the papacy for the next 100 years.
Guy III of Spoleto was the margrave of Camerino from 880 and then duke of Spoleto and Camerino from 883. He was crowned king of Italy in 889 and emperor in 891. He died in 894 while fighting for control of the Italian Peninsula.
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.
Guaimar II was the Lombard prince of Salerno from 901, when his father retired to a monastery, to his death. His father was Guaimar I and his mother was Itta. He was associated with his father in the principality from 893. He was responsible for the rise of the principality: he restored the princely palace, built the palace church of San Pietro a campanile, and restored gold coinage.
Docibilis II was the ruler of Gaeta, in one capacity or another, from 906 until his death. He was the son of the hypatus John I, who made him co-ruler in 906 or thereabouts.
Nicholas Epigingles, better known by his Latinized surname Picingli, was a Byzantine general active in southern Italy and the Balkans. As strategos of the thema of Longobardia, he led the Byzantine contingent of the Christian league in the Battle of Garigliano in 915. He was killed fighting against the Bulgarians, probably in the Battle of Acheloos on 20 August 917.
Docibilis I was the Hypatus of Gaeta from 867 until his death.
Landulf I, sometimes called Antipater, was a Lombard nobleman and the Prince of Benevento and of Capua from 12 January 901, when his father, Atenulf I, prince of Capua and conqueror of Benevento, associated his with him in power.
Alberic I was the Lombard Duke of Spoleto from between 896 and 900 until 920, 922, or thereabouts. He was also Margrave of Camerino, and the son-in-law of Theophylact I, Count of Tusculum, the most powerful man in Rome.
Gregory IV was the firstborn son of Duke Sergius II of Naples and successor of his paternal uncle, Bishop Athanasius, in 898, when he was elected dux, or magister militum, unanimously by the aristocracy. His other paternal uncle, Stephen, succeeded Athanasius as bishop. According to the Chronicon ducum et principum Beneventi, Salerni, et Capuae et ducum Neapolis, he reigned for sixteen years and eight months.
The Principality of Capua was a Lombard state centred on Capua in Southern Italy, usually de facto independent, but under the varying suzerainty of Holy Roman and Eastern Roman Empires. It was originally a gastaldate, then a county, within the principality of Salerno.
The Duchy of Rome was a state within the Byzantine Exarchate of Ravenna. Like other Byzantine states in Italy, it was ruled by an imperial functionary with the title dux. The duchy often came into conflict with the Papacy over supremacy within Rome. After the founding of the Papal States in 756, the Duchy of Rome ceased being an administrative unit and 'dukes of Rome', appointed by the popes rather than emperors, are only rarely attested.
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.
