We begin our Exarchate of Ravenna polity in 568 CE, the date of the last praetorian prefect in Italy, although the first ’exarch’ (essentially a governor with political and military authority) known by name dates to the last decades of the 6th century.
[1]
This year saw Lombard and Germanic tribes invade northern Italy, expelling the Byzantine influence in the area which the Byzantine Emperor Justinian I (r. 527-565 CE) had established only about a decade earlier. The Exarchate of Ravenna together with most of central Italy and parts of the south were the only parts of the former Ostrogothic Kingdom to remain under Byzantine authority after this time. Shortly afterwards, perhaps around 575 CE or slightly later, the first exarch of Ravenna was created under the aegis of the Byzantine emperor.
[2]
The Exarchate period ended when the last exarch, Eutychius, was killed during the Lombard conquest of the territory in 751 CE. However, recognition of the nominal Byzantine authority in the region persisted until 781 CE, when the years of the emperor’s reign were no longer used for dating papal documents or on the coins minted in Rome.
[3]
Population and political organization
The Exarchate of Ravenna was essentially a special province of the East Roman Empire and the exarch owed nominal allegiance to the emperor in Constantinople. The Roman Senate was last known operating in 580 CE
[4]
and many of the senators moved to Constantinople ’to maintain access to court appointments’.
[4]
In Italy, Ravenna was the undisputed home and capital for the army and civil administration.
[5]
The exarch was a ruler who combined civil and military powers,
[6]
commanding over 50,000 square kilometres of land in Italy after a period of protracted warfare had destroyed the Roman-friendly Ostrogothic governmental system.
[4]
His duties included leading the army in Italy, publishing and enforcing laws and canons of church councils, and appointing most subordinate officials.
[1]
Exarchs were appointed by the East Roman Emperor from among the personnel of his palace administration in Constantinople ’and rarely had served in any capacity in Italy before being named exarch’.
[1]
The criteria for choosing exarchs is not entirely clear, nor is it certain how long they might have expected their official tenure to last.
[6]
What is clear is that the exarch retained a great deal of authority and autonomy in the region.
Under the exarch, dukes of provinces ruled from cities (e.g. Rome, Naples, Rimini, Venice) and tribunes governed in towns. Like the exarch himself, the role of dukes and tribunes combined both military and civic duties. However, these men, ’along with the lower-level officers and troops, administrators, clerks, and tax collectors were drawn primarily from the local population, including educated laymen, although on occasion an official might be sent from Constantinople’.
[7]
Ravenna was governed both directly by the exarchal administration
[7]
and, until the mid-7th century, a city council (curia) responsible for tax collection and certifying and storing legal documents.
[8]
Decentralization from 600 to 750 CE weakened the authority of the exarch,
[9]
and as government collapsed, the dukes in the provinces gained power.
[10]
The 7th century CE saw the development of an ’increasingly closed and hereditary land and officeholding aristocracy’.
[11]
Another important rival of the exarch’s authority was the archbishop of Ravenna. The exarch worked with the archbishop of Ravenna ’in legal cases, foreign affairs, papal relations, and other similar sorts of situations’,
[12]
but sometimes they clashed on ’doctrinal matters’.
[13]
The Church also financed public works projects, such as building churches and public baths.
[14]
Italy experienced a slight population expansion during this period, and had perhaps over one million inhabitants.

Decentralization trend throughout period, as well as a power struggle between the Papacy in Rome and the Exarch of Ravenna, the nominal representative of the East Roman Emperor in Constantinople. The Byzantines appeared to abandon Liguria, the Lazial and Tuscan Maremma in the 640s CE.

568 CE start date+ the reforms of the East Roman Empire which ended the Praetorian Prefect of Italy and created the Exarchate of Ravenna.
However, "The earliest document that remains to us in which we find definite mention of the exarch is the famous letter, dated October 4, 584, of Pope Pelagius II. to the deacon Gregory, his nuncio in Constantinople."
[1]
+Or 575 CE, "The new order was created at the end of the reign of Justin II. (565-578)",
[1]
when Baduarius commanded the imperial armies in Italy against the Lombards "he was supreme governor of the province. And it seems certain that it was to mark the amalgamation in him of the two offices, military and civil, that the new title of exarch was created."
[1]
Ended when the Exarchate was conquered by the Lombards 751 CE who killed Eutychius, the last Exarch. However, formal recognition of nominal Byzantine authority persisted until 781 CE when the years of the Byzantine Emperor’s reign were no longer used for dating Papal documents or on the minting of imperial coins in the mint of Rome.

Nominal allegiance to the East Roman Emperor in Constantinople.
"By the year 600, the leader of Byzantine administration was a figure called the exarch."
[1]
"The exarchs were always sent from Constantinople, but we do not know the criteria by which such officials were chosen, or how long they might have expected their official tenure to last."
[1]
"The exarch was the emperor’s direct representative in Italy, and in theory he had a very narrow scope for personal inititive. Only on rare occasions did his term of office exceed six or seven years. His duty was to lead the exercitus Italicus, administer the province during the pleasure of his imperial master, publish laws and canons of church councils, and appoint most subordinate officials."
[2]
Under the Byzantines, Ravenna had status of provincial capital.

This needs a bracket, to reflect the extraordinarily tentative hold the Byzantines had on Rome from the early eighth century on; by the beginning of the polity period, the papacy was effectively independent, or at least left to its own devices for defence, due to the Byzantine focus on defending Constantinople from Arab attacks, especially before the last Arab siege of Constantinople, in 717-718 CE. [1]

Decentralization trend throughout period. In 727 CE there was a general rebellion against Byzantine officials, with the Exarchate joined by Venice. In Ravenna, the exarch was killed and cities elected their own Dukes. [1]

Exarchate of Ravenna refers to a region around the capital of this polity/sub-polity.
[1]
"Geographically the exarchate of Ravenna was bounded on the north by the Adige, the Tartaro, and the principal branch of the Po as far as its confluence with the Panaro. Hadria and Gabellum were its most northern towns in the hands of the imperialists. The western frontier is more difficult to determine with exactitude; it may be said to have run between Modena and Bologna. On the south the Marecchia divided the exarchate from the Dutchy of the Pentapolis whose capital was Rimini.

"once the court moved to Ravenna, its bishops likewise rose in the hierarchy of the Italian church, eventually holding the rank of archbishop, ranking second after the pope and making periodic bids for autocephaly, or independence from the papal see."

1. Bishop of a patriarchate
"The churches organized themselves along the lines laid down by the geography and political order of the empire. A city (civitas), along with its surrounding rural perimeter, the foundation of imperial organization, also formed the basic unit of ecclesiastical structure. Virtually every Roman city, many of them quite small, had its own bishop. He exercised his authority over a "diocese" that ordinarily coincided with the boundaries of the civitas. These dioceses were then grouped into provinces, over which a metropolitan, the bishop of a province’s principal city, held sway. Eventually, provinces themselves were organized into large "patriarchates," each lead by one of the five preeminent bishops of the church: those in Rome, Constantinople (called "New Rome," second in prestige to the Old), Antioch, Alexandria, and Jerusalem."
[4]
2. Metropolitan, with authority over a province
3. Bishop in civitas, with authority over a diocese
4. Presbyters or priests (elders)"Evidence from the second century suggests that a wide variety of models for local clergy existed throughout the Roman Empire. Yet the one to prevail was a three-tiered, hierarchical. In this model, the bishop served as leader of the local community and was assisted by presbyters or priests (elders) and deacons. Again, this model was established in the Antioch of Ignatius, as he underscores emphatically the necessity of gathering for learning, ritual, and teaching around a single bishop. By the end of the century this three-tiered form of ministry had spread to most early Catholic communities throughout the empire, and it would soon become the sole authoritative manner of organizing local ecclesial communities."

Baths and water supply system still operational at time of Agnellus writing early 9th CE. [1] Water channels used for fresh water in Early Medieval Italy. However, not necessarily built by state. "From the fourth century onward, in fact, water evergetism in the peninsular survived by assuming new forms. Much as was the case in ninth-century Le Mans, in late antique Italy bishops replaced secular builders of aqueducts. Indeed, by Aldric’s day, Italy had developed a distinguished tradition of episcopal involvement in urban water supply. [2] At least until the barbarian invasions Ravenna had a "dense urban fabric that included public amenities such as theaters and baths, acqueducts and sewers, elaborate Roman-style houses for the elite, and evidence of long-distance trade." [3] "Ravenna was not, as far as we know, sacked in any of the invasions or wars that beset the Italian peninsular, perhaps testimony to its perceived invulnerability provided by the swamps of the Adriatic coast."

This may have been a stake and ditch palisade, a type of fortification known elsewhere in Italy at the time, and is assumed to have been made in response to Lombard aggression." [2]
