Transition from Late Antiquity (6th to 8th centuries)

Italy was invaded by the

Theodoric, who had lived long in Constantinople, is now generally considered a Romanized German, and he in fact ruled over Italy largely through Roman personnel. The Goth minority, of Arian confession, constituted an aristocracy of landowners and militaries, but its influence over the country remained minimal; the Latin population was still subject to Roman laws, and maintained the freedom of creed received by Odoacer. The reign of Theodoric is generally considered a period of recovery for the country. Infrastructures were repaired, frontiers were expanded, and the economy well cared for. The Latin culture flourished for the last time with figures like

(although in the east the Greek authors were much better preserved). After the Lombard invasion, the popes were nominally subject to the eastern emperor, but often received little help from Constantinople, and had to fill the lack of stately power, providing essential services (ex. food for the needy) and protecting Rome from Lombard incursions; in this way, the popes started building an independent state.


Early Middle Ages (8th to 9th centuries)


Collapse of the Exarchate

At the end of the 8th century the popes definitely aspired to independence, and found a way to achieve it by allying with the

, were enclaves who were becoming increasingly independent from Byzantium. A conquest of Benevento, otherwise, would have meant the total encompassment of the Papal territories, and probably Charlemagne thought it was good for his relationships with the Pope to avoid such a move. The age of Charlemagne was one of stability for Italy, though it was generally dominated by non-Italian interests. The separation with the Eastern world continued to increase. Leo III was the first Pope to date his Bulls from the year of Charlemagne's reign (795) instead of those of Byzantine emperors. This process of isolation from the Eastern Empire and connection with the Western world of France and Germany, which had started three centuries before, was completed at the beginning of the 9th centuries. Sicily, Calabria, Puglia and Venice were the main exceptions to this rule. After the death of Charlemagne (814) the new empire soon disintegrated under his weak successors. The equilibrium created through the great emperor's charisma fell apart. This crisis was due also to the emergence of external forces, including the

Southern Italy

With Charlemagne's conquest of 774, the north of Italy was politically separated from the south completely. Though the Byzantines had continued to hold most of Apulia and Calabria and the Lombard duchies of the south had been aloof of Pavian policies for a century, the situation was exacerbated by the loss of a centralising Lombard authority in the north.


Creation of independent moieties (774–849)

Under Arechis II of Benevento and his successors, it was the Beneventan policy to pay homage to the Carolingian emperors but ignore their rulings. As a result, ''De facto'' independence was achieved from Frankish as well as Byzantine authority. The Duchy of Benevento reached its territorial peak under Sicard in the 830s. At his time, the Mezzogiorno was suffering the ravages of the

, invaded the peninsula and imposed peace between the Lombard factions. He divided the principality into two: one at Benevento, one at Salerno. Thenceforward, the history of the Lombard south is one of declining, competing powers. In the Tyrrhenian Greek cities, the violence raging inland, between them and their fellow Greeks on toe and heel, fostered the circumstances of ''de facto'' independence. Naples, in particular, had a history of differences with Byzantium and had in the past sought to make herself dependent on other authorities, often papal. In 801, the Byzantine patrician of Sicily succeeded in creating Anthimus duke. However, Anthimus was unable to control the cities under his rule, Gaeta and Amalfi. Subsequent to Anthimus, the patrician tried to appoint his own candidate without imperial approval. The people rebelled and accepted Stephen III in 821. During Stephen's decade of rule, Naples severed all legal ties to Constantinople and even began minting her own coins. In 840, after a brief flirtation with Frankish servitude, to Lothair I, and a Frankish duke, in the person of Duke Contard, the Neapolitan citizenry elected Sergius I their ''

''. Sergius established a dynasty, the Sergi, that was to rule the duchy for the next three hundred years. In Gaeta, as in Naples, the violent situation inland required new power structures to maintain Byzantine authority. The Gaetans received their first imperial Byzantine '' hypati'' around the time of the Beneventan civil war. While the first ''hypati'' remained Byzantine loyals, in 866, the sudden appearance of a new dynasty under Docibilis I represented Gaeta's move from Byzantium towards independence. The first elected ruler of Amalfi was a ''

Period of confusion (849–915)

The period following the Beneventan civil war was one of confusion, brought on by the independence movements in the various cities and provinces and by the Saracen onslaught. In Salerno, a palace coup removed Siconulf's successor Sico II in 853 and destabilised that principality until a new dynasty, the Dauferidi, came to power in 861. In 852, the Saracens took Bari and founded an emirate there. Greek power being significantly threatened, as well as Adriatic commerce, the Byzantine emperor requested an alliance from Louis II of Italy. Similarly, the new prince of Benevento, Adelchis, an independent-minded ruler, also sought his aid. Louis came down and retook Bari in 871 after a great siege. Louis then tried to set up greater control over all the south by garrisoning his troops in Beneventan fortresses. The response of Adelchis to this action was to imprison and rob the emperor while he was staying the princely palace at Benevento. A month later, the Saracens had landed with a new invasive force and Adelchis released Louis to lead the armies against it. Adelchis forced Louis to vow never to re-enter Benevento with an army or to take revenge for his detention. Louis went to Rome in 872 and was released from his oath by Pope Adrian II on 28 May. His attempts to punish Adelchis were not very successful. Adelchis vacillated between nominal fealty to the Carolingian and Byzantine emperors, but, in fact, by his alterations to the
Edictum Rothari The ''Edictum Rothari'' (lit. ''Edict of Rothari''; also ''Edictus Rothari'' or ''Edictum Rotharis'') was the first written compilation of Lombard law, codified and promulgated on 22 November 643 by King Rothari in Pavia by a gairethinx, an ass ...
, he acknowledged himself as the legitimate Lombard "king." The successors of Adelchis were weak and the principality of Benevento declined just as Salernitan power was beginning to make itself felt. Guaifer of Salerno was on friendly terms with the Saracens, a habit which annoyed the popes and often put a ruler at odds with his neighbours. The south Italian lords continually rotating in their allegiances. Guaifer's successor, Guaimar I, made war on the Saracens. Guaifer had originally associated Guaimar with him as co-ruler, a practice which became endemic to the south and was especially evident in Capua.

Southern Italy

Under the Macedonian dynasty, Byzantine power experienced a recovery; and the impact of this was felt in southern Italy. During the late 9th century the amount of territory under direct Byzantine rule (which in the early 9th century was limited to the toe and heel of the peninsula) expanded dramatically. The Catepanate of Italy was set up to administer the newly acquired territory. The rest of Southern Italy remained divided among the Lombard kings and the Italian cities. Both sets of principalities were de facto independent but paid nominal allegiance to Byzantium. The Southern Italy growth and change stagnated for a number of reasons. In 878 the Arabs captured the crucial city of Syracuse, and by 965 the entire island was under Arab rule.The reminisce of the

Particularly detrimental was the fact that most of the victims were young adults in their prime working years, which left behind an "hourglass" population structure comprised heavily of children and older people with fewer in-between. The widespread belief of medieval Europe having a "pyramid" population where most people were under 45 was not completely true and in fact varied widely from region to region. France traditionally had high birth rates, but Italy's fertility was lower to begin with and especially after the Plague had ravaged the region, many cities such as

, Verona, and Arezzo had populations where more than 15% of people were over the age of 60. Since overall life expectancy in Europe did not increase by any significant margin during this period, the aging cohort in some areas can be almost completely blamed on the effects of the Plague. Wealthy households had larger numbers of children than the poor. For example, in the early 15th century, the average age of Florence's population among the lower classes was 25 while the upper classes had an average age of just 17.
