Year 1137 (MCXXXVII) was a common year starting on Friday of the Julian calendar.
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.
Philip I of Taranto, of the Angevin house, was titular Latin Emperor of Constantinople by right of his wife Catherine of Valois–Courtenay, Despot of Romania, King of Albania, Prince of Achaea and Taranto.
Liutprand was the king of the Lombards from 712 to 744 and is chiefly remembered for his multiple phases of law-giving, in fifteen separate sessions from 713 to 735 inclusive, and his long reign, which brought him into a series of conflicts, mostly successful, with most of Italy. He is often regarded as the most successful Lombard monarch, notable for the Donation of Sutri in 728, which was the first accolade of sovereign territory to the Papacy.
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."
The Duchy of Naples began as a Byzantine province that was constituted in the seventh century, in the reduced coastal lands that the Lombards had not conquered during their invasion of Italy in the sixth century. It was governed by a military commander (dux), and rapidly became a de facto independent state, lasting more than five centuries during the Early and High Middle Ages. Naples remains a significant metropolitan city in present-day Italy.
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.
Athanasius was the Bishop and Duke of Naples from 878 to his death. He was the son of Gregory III and brother of Sergius II, whom he blinded and deposed in order to seize the throne while he was already bishop.
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.
Sergius II was Duke of Naples from 870 to 877.
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.
Stephen II was the duke of Naples during an important transitional period in its history, from 755 to his death. He was styled as eminentissimus consul and was the leader of the local aristocracy when he was appointed by the patrician of Sicily. By the end of his reign, through a rupture with the Byzantine Empire, Naples was practically independent. After his abdication, Naples experienced a period of crisis until the election of Sergius I in 840.
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.
Centurione II Zaccaria, scion of a powerful Genoese merchant family established in the Morea, was installed as Prince of Achaea by Ladislaus of Naples in 1404 and was the last ruler of the Latin Empire not under Byzantine suzerainty.
The Sacred Military Constantinian Order of Saint George (SMOCG) (Italian: Sacro Militare Ordine Costantiniano di San Giorgio, Spanish: Sagrada Orden Militar Constantiniana de San Jorge), also historically referred to as the Imperial Constantinian Order of Saint George and the Order of the Constantinian Angelic Knights of Saint George, is a dynastic order of knighthood of the House of Bourbon-Two Sicilies. Currently, the grand magistry of the order is disputed among the two claimants to the headship of the former reigning House of Bourbon-Two Sicilies as heirs of the House of Farnese, namely Prince Pedro and Prince Carlo. The order was one of the rare orders confirmed as a religious-military order in the papal bull Militantis Ecclesiae in 1718 owing to a notable success in liberating Christians in the Peloponnese. Together with the Sovereign Military Order of Malta and the Order of Saints Maurice and Lazarus (confirmed by papal bull in 1572) it is one of the three international Catholic Orders that still has this status today. Although it is not an order of chivalry under patronage of the Holy See, membership is restricted to practising Catholics.
Theoctistus was the Duke of Naples during an ill-recorded period in its history. His reign began sometime around 818 and lasted until 821.
The Capetian House of Anjou, or House of Anjou-Sicily, was a royal house and cadet branch of the direct French House of Capet, part of the Capetian dynasty. It is one of three separate royal houses referred to as Angevin, meaning "from Anjou" in France. Founded by Charles I of Anjou, the youngest son of Louis VIII of France, the Capetian king first ruled the Kingdom of Sicily during the 13th century. The War of the Sicilian Vespers later forced him out of the island of Sicily, which left him with the southern half of the Italian Peninsula, the Kingdom of Naples. The house and its various branches would go on to influence much of the history of Southern and Central Europe during the Middle Ages until it became extinct in 1435.
The Norman conquest of southern Italy lasted from 999 to 1139, involving many battles and independent conquerors.
Theoctistus or Theoktistos is a Greek name derived from θεος theos, "god", and κτίσμα ktisma, "creation, edifice, foundation", the resulting combination being translated to "creation of God", "godly creation".
