, were enclaves who were becoming increasingly independent of 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 century. 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.

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

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.

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

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.

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. The countryside became swiftly depopulated after the Plague as well due to surviving young people moving en masse to the cities.
