King of Sicily in the context of "Frederick II, Holy Roman Emperor"

Charles V (24 February 1500 – 21 September 1558) was Holy Roman Emperor and Archduke of Austria from 1519 to 1556, King of Spain (as Charles I) from 1516 to 1556, King of Sicily and Naples from 1516 to 1554, and also Lord of the Netherlands and titular Duke of Burgundy (as Charles II) from 1506 to 1555. He was heir to and then head of the rising House of Habsburg. His dominions in Europe included the Holy Roman Empire, extending from Germany to northern Italy with rule over the Austrian hereditary lands and Burgundian Low Countries, and Spain with its possessions of the southern Italian kingdoms of Sicily, Naples, and Sardinia. In the Americas, he oversaw the continuation of Spanish colonization and a short-lived German colonization. The personal union of the European and American territories he ruled was the first collection of realms labelled "the empire on which the sun never sets".

Charles was born in Flanders to Habsburg Archduke Philip the Handsome, son of Maximilian I, Holy Roman Emperor and Mary of Burgundy, and Joanna of Castile, younger child of Isabella I of Castile and Ferdinand II of Aragon, the Catholic Monarchs of Spain. Heir of his grandparents, Charles inherited his family dominions at a young age. After his father's death in 1506, he inherited the Habsburg Netherlands in the Low Countries. In 1516 he became King of Spain as co-monarch of Castile and Aragon with his mother. Spain's possessions included the Castilian colonies of the West Indies and the Spanish Main, as well as Naples, Sicily, and Sardinia. At the death of his grandfather Maximilian in 1519, he inherited the Austrian hereditary lands and was elected as Holy Roman Emperor. He adopted the Imperial name of Charles V as his main title, and styled himself as a new Charlemagne.

Charles I (Italian: Carlo; early 1226/1227 – 7 January 1285), commonly called Charles of Anjou or Charles d'Anjou, was King of Sicily from 1266 to 1285. He was a member of the Capetian dynasty and the founder of the House of Anjou-Sicily. Between 1246 and 1285, he was Count of Provence and Forcalquier in the Holy Roman Empire and Count of Anjou and Maine in France. In 1272 he was proclaimed King of Albania, in 1277 he purchased a claim to the Kingdom of Jerusalem, and in 1278 he became Prince of Achaea after the previous ruler, William of Villehardouin, died without heirs.

The youngest son of Louis VIII of France and Blanche of Castile, Charles was destined for a church career until the early 1240s. He acquired Provence and Forcalquier through his marriage to Beatrice. His attempts to restore central authority brought him into conflict with his mother-in-law, Beatrice of Savoy, and the nobility. He relinquished control of Forcalquier to his mother-in-law in 1248, although she returned it to him in 1256. Charles received Anjou and Maine from his brother, Louis IX of France, in appanage. He accompanied Louis during the Seventh Crusade to Egypt. Shortly after he returned to Provence in 1250, Charles forced three wealthy autonomous cities—Marseille, Arles and Avignon—to acknowledge his suzerainty.

The history of Islam in Sicily and southern Italy began with Arab colonization 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 965. Though Sicily was the primary Muslim stronghold in Italy, some temporary footholds, the most substantial of which was the port city of Bari (occupied from 847 until 871), were established on the mainland peninsula, especially in mainland southern Italy, though Arab 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 indigenous Italian forces also competing for control. Arabs were sometimes allied with various Christian factions against other factions.

In 965 the Kalbids established the independence of their emirate from the Fatimid Caliphate. In 1061 the Normans took Messina, and by 1072 Palermo and its citadel were captured. In 1091 Noto also fell to the Normans, and the conquest was complete. Malta fell later that year, though the Arab administration was kept in place, marking the final chapter of this period. The conquests of the Normans established Roman Catholicism firmly in the region, where Eastern Christianity had been prominent during the time of Byzantine rule and even remained significant during Islamic period. In 1245, Muslims were deported to the settlement of Lucera, by order of Frederick II, king of Sicily. In 1300, Giovanni Pipino da Barletta, count of Altamura, seized Lucera and exiled its population, bringing an end to the medieval Muslim presence in Italy.

Roger II or Roger the Great (Italian: Ruggero II, Sicilian: Ruggeru II, Greek: Ρογέριος; 22 December 1095 – 26 February 1154) 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.

The Viceroys of Sicily (Italian: Viceré di Sicilia) were the regents of the government of the Kingdom of Sicily in place of the Spanish Kings who acquired the title of King of Sicily from 1412 to 1759. In 1806 Ferdinand I of the Two Sicilies, having established himself on the island, abolished the office and established in its place those of lieutenant and captain general.

This is a list of the oldest existing universities in continuous operation in the world.

Inclusion in this list is determined by the date at which the educational institute first met the traditional definition of a university used by academic historians although it may have existed as a different kind of institution before that time. This definition limits the term "university" to institutions with distinctive structural and legal features that developed in Europe, and which make the university form different from other institutions of higher learning in the pre-modern world, even though these may sometimes now be referred to popularly as universities.

The Hauteville family (Italian: Altavilla, Sicilian: Autaviḍḍa) was a Norman family, originally of petty lords, from the Cotentin Peninsula in Normandy. The Hautevilles rose to prominence through their part in the Norman conquest of southern Italy. In 1130, Roger II of Hauteville, was made the first King of Sicily. His male-line descendants ruled the kingdom until 1194. The Hauteville also took part in the First Crusade and ruled the independent Principality of Antioch (1098).
