Byzantium

 Constans II, with Constantine IV (641-668)

AU Solidus, 19mm,  4.34 gr.  Struck 654-659. Obv: ..CONSTANTINVS . CON .., crowned and draped busts facing of Constans II, to left, and Constantine IV, to right; cross above. Rev": VICTORIX ....., Cross potent on three steps over CONOB. Mint is Constantinople. Seller ID: DOC II 25d; SB 959.

In the 4th C Constantine moved the capital of Rome to Constantinople (Istanbul today). When the Western Empire fell to the Ostrogoths in the 5th C, Byzantium held territory on the Italian peninsula and in 535 Sicily came under Byzantium control. Much of this mainland territory was initially lost in the Lombard invasion but Sicily remained in Byzantine hands. 

In 660 Constans moved the capital the the Byzantine empire back to the West and for 5 years Sicily (Syracuse) was capital of the empire, before this decision was reversed.  This coin is linked to more to Constans II than Italy, but earns a place here since since he moved the capital (and it's a neat coin).

Byzantium experienced a resurgence in the 9th C and  reacquired extensive territory in southern Italy, about the same time Sicily was succumbing to Arab pressure. Syracuse remained an important Byzantium outpost, but one increasingly vulnerable to the Arab threat. In 827, when the Byzantium admiral Euphemius revolted against the emperor, he called on Arab forces in north Africa to help him in his conflict. His goal was to become ruler of Sicily but he effectively opened the island to Islamic invasion. Sicily fell to the Arab invaders in 878, essentially establishing Arab dominance on the island. Fighting continued for almost 100 years and Messina fell in the 10th C. Fighting finally ended when the last mountain stronghold fell in 965.

Carolingian

Louis II of Italy (855-875)

AR denier, 17mm, 1.1gr. Obv: +LVDOVVICVS INP, central cross over lines. Rev: +ANGILBERGA NP, central cross with eight rays. Mint is Benevento (It). R2013; MG 1178; Dep 10-F1, 141M (8 examples); MEC 1116; not in Prou. Note the cross potent, similar to Constans II above.

Louis II is descended from Louis the Pious via his son first Lothar. Lother I's inheritance from his father was the central Carolingian territory, running from the Low Countries through Burgundy down into Italy. When he died, his first son, Lothar, inherited the northern part of his father's lands, to be called Lotharingia, while his other son inherited Italy and ruled as Louis II.

At the time this coin was minted mainland Italy was subject to Arab raids and invasion. Disunity among the Italian princes made effective resistance difficult and the trade relationships coastal cities had with the Arabs made them less than enthusiastic to fight their Arab trading partners. Coastal communities were glad to see the Lombard hold on southern Italy weakened. Even the intervention of Louis II was unable to generate a sustained effort against the Arabs. It was only in the early 10th C that the Arabs were finally driven out of the mainland, although they continued to hold Sicily. In addition to the Arab threat, the Byzantium resurgence in this century caused attention to focus as well on the east coast of Italy, Byzantium's stronghold. Benevento fell to Byzantine forces in 891, who succeeded in holding it only for four years.

Kingdoms of Sicily and Naples

Maps from Loud, The Age of Robert Guiscard 

At the start of the 11th century southern Italy was a cultural melange. Lombards controlled territory on the mainland, as did Byzantium. At the same time, Sicily was under Islamic control. Islamic forces were once against pressuring the mainland and raiding extensively, penetratring as far as Benevento in 1102. (Loud 29) In  addition to the native Sicilians and Italians in the region, there was a significant Jewish population in southern Italy and Sicily.  Most broadly, as Takayama (5) describes it, 'Thus, in the 11th century the Mediterranean world consisted of three major cultural zones: Latin-Christian Western Europe, Greek-Christian Byzantine East and Arab-Islamic north Africa and Spain. Southern Italy and Sicily formed their borders." However, Smith (32) notes "... in the passage of time, it became clear that these cultural traditions had mixed but never completely fused." This would set the stage for strife in the 12th C.

The Normans arrived in the south, on the mainland, in the second decade of the 11th C. They were drawn by pilgrimage and opportunity. Their military skills were utilized by both Greeks and Lombards and as time went on, their numbers increased and they began to carve out their own territory. They were both allies and enemies of the 11th C papacy. Out of this fluid political environment Robert Guiscard emerged as the dominant figure who was recognized as count of Apulia. As the Normans strengthened their hold on the southern mainland, their attention turned to Sicily. It is at this point that Roger I enters the picture.

Roger I: count of Sicily (d 1101)

AU Tari d'oro, 13x14mm, .97gr. Obv: SE NON/MAOMETTO EL'INVIATO DI DIO/NON VE DIVINITA. Central Arabic script. Rev: grand T with globes. Mint is Messina. B1211.

Roger was Robert Guiscard's brother and is responsible for the Norman conquest of Sicily. By the middle of the 11th C Arab rule weakened due to infighting throughout the Arab world and particularly among the competing Islamic rulers in Sicily. The Normans saw an opportunity to take advantage of this weakness and expand their southern Italian lands. In 1061 Roger led a small force into Sicily, to reconnoiter, to plunder and to test the level of resistance. The Norman invasion, with some complicity on the part of conflicting Islamic rulers, commenced in 1060. Shortly thereafter Roger captured Messina, just across the straits from Italy, and continued to expand his control in the NE of the island.  In 1071 Palermo fell to Robert Guiscard and by 1091 Sicily was largely captured.

While the Saracens were in control of the island, they were largely tolerant of other religions (Greek Orthodox, Jews, Latin Christians) and Roger continued this tradition, including toleration of Islam. The Normans represented a conquest by a relatively small number of invaders and not a population migration. They therefore needed the current population to farm the land and provide the craftsmanship necessary to support Sicilian commerce. Roger relied on Orthodox Greeks to staff his government administrative offices and was tolerant of the Muslim population. His reliance on the Greeks gave his government a decidedly Byzantine flavor, very unusual for a Latin ruler.

While Sicily was not a source of gold, Roger was able to mint gold coins, many of which have survived, due to the gold Sicily earned in exchange for grain sold in north ASfrican markets.

Given the complex population he conquered and the relatively good relations he had with the Arabs, in Sicily and in Africa, he was not a supporter of the First Crusade. He came to be recognized as count of Sicily and died in 1101 and was buried in Calabria, the mainland province that fell under his rule.

Roger II: king of Sicily (1130 - 1154)

Roger succeeded his father as ruler of Sicily. During his minority Roger I's wife, Adelaide, acted as regent. Adelaide married king Baldwin of Jerusalem in 1113 and left for the Middle East. By this time Roger II had assumed control of his government. Roger ultimately inherited Apulia and came to control all of southern Italy. In 1130 he proclaimed himself  king of the Kingdom of Sicily, with the consent of his major vassals. Following an old tradition, he was crowned in Palermo on Christmas day, choosing the same date Charlemagne was crowned in 800.

Roger shared his father's lack of enthusiasm for the crusades but profitably provisioned travelers going the the Middle East. He took advantage of the passage of the Second Crusade and seized Corfu for his kingdom in 1147. He also extended his reach into north Africa and his forces seized Tripoli in 1146 and other coast areas into 1148. This map shows the extent of his kingdom, based in Sicily and southern Italy but extending into the Adriatic and across the Mediterranean by 1150.

Roger had a mixed relationship with the Roman church. He was ocassionally excommunicated and fought with popes but was crowned by a pope, without recognizing the pope's temporal authority. He was generous in his support of the church, both Roman and Byzantine, but favored Romans for the better ecclesiastical positions. He claimed the right to appoint bishops, something the popes had generally been successful in keeping to themselves in other parts of Europe.

William I: king of Sicily (1154 - 66)

William I is son of Roger II. His reign was more troubled than that of his father. His nobles were becoming more assertive and he faced a number of rebellions. The Arabs in north Africa were recapturing the lands Roger II had taken and by 1160 they had returned to Islamic hands. The relative cultural and religious tolerance of the previous reign gave rise to Christian-Islam tensions. William was seized by rebels at one point and his son was proclaimed king. This conflict weakened commerce and impaired prosperity and encouraged Islamic out migration. When William regained his independence, his retribution on the rebels was harsh.

William II is son of William I, grandson of Roger II. His mother was Margaret of Navarre and she was his regent during his minority. His reign was characterized by conflict between competing Christian factions and William's power was limited. William sponsored the Benedictine abbey at Monreale, with the hope it would become a religious counterweight to power concentrated by the bishop of Palermo. William's mother encouraged the in-migration of Spanish and Norman knights and the kingdom became increasingly Latinized. William himself was comfortable with Greek and Arab culture, although Sicily as a whole was moving towards the generalized Latin intolerance of Islam, a product of the crusades. The fact that Jerusalem fell to Saladin in 1187 acerbated Christian-Islam tensions in his lands.

William had aspirations of becoming emperor of the East and to pursue this goal he sought out a German alliance. This led to his aunt marrying Henry of the house of Hofenstuafen, who subsequently became HRE. This marraige set the seeds for the Norman loss of control of Sicily. This became much more likely since William had no direct heir.

Tancred of Sicily (1189 - 94)

For a larger image click here

Follara, 6mm, 2.44gr. Obv in Arabic: KING TANCRED. Rev: +ROVERIVS, central REX. Mint is Messina. Spahr 139v (description by Berman).

Tancred is a first cousin of William II, nephew (illegitimate) of William I. He is an illegitimate son of Roger (died 1149) who in turn is a son of Roger II. Tancred had two sons who briefly claimed kingship of Sicily (Roger III, 1192 - 93 and William III, 1194) but neither appear to have had coinage. Tancred came to the throne during a conflict over succession, since William II died without an heir. Tancred was supported by a number of barons who recognized that any conflict over the throne would weaken the monarchy and thereby effectively shift power to them. Tancred had allies beyond Sicily in pursuing his claim. The alternate claimant was Henry of Swabia, husband of his aunt Constance. The pope was not enthusiastic about having a German presence both north and south of Rome, given his conflicts with the HRE, and therefore favored Tancred. It is possible the Byzantium also favored Tancred, who was culturally sympathetic to Greek ideas. Tancred died when he was only 39 and the throne passed via his aunt to German control.

Tancred had a hard reign. He found himself the unfortunate host of Richard the Lion Hearted and Philip August who stopped (and looted) in Sicily on their way to the Holy Land during the Third Crusade. This visit was complicated by the fact that Richard's sister, Joanna, was the widow of William II, and Richard claimed that her dowry should be returned since William died. This six month visit contributed to the erosion of Tancred's authority, as did the constant opportunistic pirate raids on the Sicilian coast during his reign. He also lost authority to the Church, which was able to assert ecclesiastical control it has not been able to exercise under earlier rulers.

Constance was a daughter of Roger II and sister of William I and aunt of William II. She became queen of Sicily in 1195, after the death of Tancred and his sons. She married Henry of Swabia, which took the line out of direct Norman control and passed it to the Germans. Henry was son of Barbarosa, who died on the Third Crusade. Whereas as the Normans had Sicily as their central focus, Henry saw it as an incidental part of of his German territories. He essentially looted Sicily and carried its treasures back to Germany. Henry and Constance died within a year of each other aqfter a short reign and left a very young Frederick II as their heir. He had to rely on the papacy protection, which turned out to be fairly ineffective, given the limited resources of the papacy and the rapaciousness of the German nobles who had settled in Sicily. Henry's greatest legacy was the intorduction of Germanic influence and Germanic nobility into Sicily. Neithyer seemed to serve Sicily well.

Frederick was a most interesting person and ruler. His life started with a very public birth - his mother was 40 and hadn't had any children so when her time came she set up a tent and invited people to witness the birth, so there was no question she was actually the mother and Frederick her son. He was named Frederic Roger, reflecting both his German and Norman ancestry. He was only three when his parents died. His mother Constance paid the pope to act as his protector but the pope joined the German nobles introduced by Henry VI in trying to turn Sicily into a private fief. Frederick had several wives, serially, and a harem, coincidentally. He apparently lived a sensuous and sexually focused life, leaving behind a string of illegitimate offspring by several women. His first marriage was arranged by the pope (Innocent III) to Constance of Aragon. Her primary attraction to the pope was that she wasn't German. Popes feared having their territorial interests pressed from both north and south by Germanic controlled lands.

When he came of age he asserted his control over Sicily and put down repeated rebellions against his authority. Several writers speak of his cruelty in dealing with organized dissent. Italy was his primary interest and even though he was crowned HRE and ruler of substantial German territory, he farmed out the ruling of those lands to his son and other German nobles. He spend most of his time in Italy, where he introduced governmental reforms that actually did not long survive his death in 1250. He was the founder of a university in Naples that functioned as a secular, in contrast to religious, university. It was the first secular university in Europe, earlier ones having been founded on strong religious grounds. His goal was to produce an educated cadre of people with law and administrative backgrounds who could help run his lands. He provided financial incentives for teachers and students to come to Naples, as well as closing competing schools in his territory. His focus in Naples contributed to its rise as a major city in successive centuries.

As HRE, the Church and secular leaders looked to Frederick for leadership in asserting Christian goals in the middle east. Jerusalem, which was captured by the First Crusade, fell to Saladin in 1187. The Church was keen to recapture it and Frederick was under constant pressure to go crusading. He resisted so long and often he was excommunicated, one of several times this happened over his life. He finally went the the middle east in 1228, as much to protect the interests of a son born to a subsequent wife which allowed that child to claim the crown of Jerusalem. The legend 'king of Jerusalem' enters his coinage. His crusade was unusual in that he accomplished the goal of bringing Jerusalem back into Christian control but he did it by negotiation with the caliph of Cairo rather than by force of arms. He also did this while excommunicated, so couldn't get a celebratory mass said for himself on entering Jerusalem so he ended up crowning himself. This reacquisition of Jerusalem was a temporary phenomena and it fell again about a dozen years later. The lines of communication were too long for European interests to hold in the 13th century.

Frederick was intellectually curious and had scholars in his court. Among his interests, he was a coin collector. He was culturally interested in Islamic thought but was forceful in dealing with any kind of resistance from Islamic (or other) subjects. At one point he forcibly relocated 15,000 rebellious Muslims to the mainland as a way of asserting control in Sicily. He required Muslims and Jews and prostitutes to wear distinctive clothing as a way of setting them apart in Sicily. This was all happening as Europe was becoming even less tolerant of non-orthodox non-Christian thinking. He directed this hostility towards his subjects, and was himself the target of a 'crusade' for his unorthodox ideas and anti-papal actions. It was not successful. This was just after the time the Church supported another intra-European crusade, against the Albigensian heresy in southern France.

Frederick died in 1250 after a decently long reign. Finlet et al (p69) characterize the Hohenstaufen legacy as such: "While it belonged to the world of North Afrtica and the Levant, the island had been rich; but when forcibly attached to western Europe it lost many of the advantages of its geographical position. After 1194, Sicily was one small peripheral region in a succession of larger empires, and her wealth expended on projects in which Sicilian concerns were minimal."

Conrad was son of Frederick II, HRE. In Sicily he was Conrad I, but via other German titles he was known as Conrad IV. His reign was short and ineffective and he never really established control over Sicily. This was a time of turmoil for the island, as it came into political play more dramatically than during Frederick's life. Frederick had been excommunicated and the pope was looking for someone other than a direct Hohenstaufen to take the throne. It was offered to Alponse of Spain (who declined) and Richard, Earl of Cornwall, who also declined. He responded along the lines, says Benjamin (206) "it was like being offered the moon, provided he could take it from the sky." Charles of Anjou also initially declined and final it was accepted by Edmund, a son of English king Henry. However the English never paid the pope nor tried to exercise the claim and the offer was subsequently rescinded. While Conrad's reign was short, he had quite a varied coinage. Here are several more examples.

Conradin was the son of Conrad I and an infant when his father died. His father placed him  in the care of Pope Innocent, which presented Innocent a dilemma since he was trying to end the Hohenstaufen reign in Sicily. Innocent's death save him from figuring out how to balance his political interests in finding a king for Sicily and the unwanted obligation to Conradin. Conradin grew up in Bavaria and never made it to Sicily, even though he was its titular king. He never effectively reigned, since he died when he was 12 while trying to claim his throne. His death came after his small army was decisively defeated by the larger force of Charles of Anjou. Conradin was captured and beheaded in Naples.

Manfred is an illegitimate son of Frederick II, HRE and brother of Conrad I (died 1254). He was crowned in Palermo in 1258 and was the de facto ruler of Sicily, regardless of the claim of his nephew Conradin. He functioned both as a regent and king. I'm not aware of how succession was planned. Manfred had support in Sicily and hostility from the pope. The Sicilians saw him as a proponent of Sicilian nationalism and someone familiar with their culture and traditions. He was successful in exerting control over Sicily and extending it to the southern Italian peninsula. By this time the papacy was help by Urban IV, a Frenchman. After the previous failed efforts to get an Englishman on the Sicilian throne, Urban turned again to Charles of Anjou, brother of the king of France. This time around, Charles was more interested in the prospect of his own kingdom and accepted the Urban's offer of the crown. Charles entered Italy with papal support and a large army to pursue his claim. He and Manfred met near Benevento in 1266 and defeated him in combat. Manfred was killed in this battle.

While king, in about 1259, Manfred married his daughter (Constance) to Peter of Aragon, heir to that throne. This marriage opened the door to Sicily for the Aragonese after the revolt of the Sicilian Vespers.

Charles had territorial interests in both Italy and Provence. He received a papal offer of the crown of Sicily from Urban IV. 

Popes propose but others contest. In Italy Charles ran into problems. He manipulated the execution of Conradin, successor to Barbarossa and Frederick II and heir of king Manfred. His death angered the Italians, who held no love for the French. The French imposed strict controls over Italian territories, rankling the local populace. In response to an instance of French abuse, particularly the supposed abuse of a Frenchman (soldier?) of a Sicilian woman on March 30, 1282, the citizens of Palermo rose against the French, slaughtering thousands. This episode is referred to as the night of the Sicilian Vespers. This revolt in Palermo quickly spread throughout Sicily and ultimately led to a complete French withdrawal from the island. Charles had to defend his nearby territories on the mainland. Charles made his headquarters in Naples and the island and mainland began to have significantly different experiences. Sicily soon fell under Aragon's control and turned to Spain while the peninsula remained focused on the papacy and north. Sicily lost access to the university in Naples, which weakened the educational base of the island. 

This conflict in Sicily was further complicated by the fact that the next pope (Nicholas III) sought greater control over Italy than his predecessor had exerted. Nicholas wanted to rule Italy himself. In a negotiation with the Hapsburgs (who were papal allies at the time) and Charles, Charles was to relinquish Sicily in return for the kingdom of Arles and Vienne. (The crown would actually go to his heir - Charles the Lame.)  After the episode if the Sicilian vespers Charles no longer had Sicily to relinquish. However, he was prepared to fight to regain it. 

After Charles' death Sicily goes to Aragon.

 

Charles, being of royal blood, was entombed in St. Denis outside of Paris, burial place for the French kings. This is the effigy from his tomb.
