Medieval Bologna
The medieval period in Bologna spans from the end of the Gothic War in 553 ce to 1401, when Giovanni I Bentivoglio proclaimed himself signore of Bologna. After the Gothic War, in the mid-6th century, at first Etruscan and later Roman settlement of Bologna came within the sphere of influence of the Exarchate of Ravenna and subsequently in the hands first of the Carolingians and then of the kings of Italy (9th–10th centuries). The city was governed by a count, like the other regions under Carolingian dominion, and then by a duke. From the 10th and particularly the 11th century, a period of economic recovery, Bologna expanded beyond the city walls, with modest dwellings housing artisans who were moving in from the countryside. At the end of the 11th century, Bologna reached a turning point in its history, with the emergence of the university—in particular, the law school. In the following centuries, students converged on Bologna from all over Europe, and the city managed to meet the needs of large numbers of students. In the 12th century the merchants, artisans, and professional classes established an autonomous form of government, the commune. Together with the other cities of northern Italy, Bologna was part of the Lombard League, and it fought against the emperor Frederick Barbarossa, who laid claim to the government of the city. The city emerged from that conflict in a state of full autonomy. In the 1150s, the second circle of defenses was constructed, the Torresotti walls, but it proved to be inadequate. In the late 1220s, a much more extensive circle of defenses was constructed, which to this day marks the limits of the historic city center. During the 13th century, various forms of city government were adopted. At the beginning of the century the government was controlled by aristocrats and entrepreneurs, giving way to a popular government (Comune di Popolo) from the middle of the century. The political tensions between the various social strata gave rise to a period of insecurity, resulting in a government intended to safeguard the economy. Various forms of government were set up in the 14th century by internal and external rulers: the local Pepoli family, and Milan’s Visconti. But the greatest threat to Bologna’s autonomy was the papacy, and the regimes of Cardinal du Pouget, Cardinal legate Guillaume de Noellet. In 1376 there was a reassertion of the Commune.
