The territory of the commune is located on the western slope of the Savena valley, on the northern ridge of Monte Venere and on the left side of the Setta and Sambro streams.
In the 12th century Monzuno was under the rule of the Marquises of Tuscany. After the Lombard overlords, it passed over to the possession of the Ubaldinis and afterwards was handed over to Matilde di Canossa. It was finally divided among the noble families of the Da Monzuno, Da Montorio and Da Panico.
Under the rule of Matilde of Canossa the Castle was part of the court of Scanello and then ceded to the Church of Pisa. Later it acquired independence under the local lordship that had branched out perhaps from the Ubaldinis. The Da Monzunos won the Da Montorios and sought for help from the church circles, taking sides with the Geremeis (who were Guelphs) against the Lambertazzi (Ghibellines). Anyway during the crisis they showed the real nature of their political tendencies, lining up with nobles to the detriment of the middle class. The Bolognese on the other hand perfectly knew the political shadiness of the noble house and hence tried to appoint them with offices and posts ensuring to contain their power. Bologna obtained then in 1371 the subjugation of Monzuno and of the Castle of Aligrano. However, as the Ghibellines of Bologna plotted to open the city's door to the Marquis Niccolò II d'Este, Guiduccio da Monzuno took sides in favour of the insurgents and decided to support the Lambertazzis. Bologna replied with resolution and sent infantry and cavalry to occupy the castle. Monzuno became a commissariat at the end of the 15th century, under the rule of Giovanni II Bentivoglio. The district was afterwards handed over in 1514 to the Manzoli family and then to the Dukes of Acquasparta.
In 1810 the commune of Monzuno was established, to which also the hamlets of Trasasso, Brigola, Gugliara, Vado, Monterumici, Brigadello, brento, Valle di Sambro, Gabbiano, Montorio and Rioveggio were incorporated. The most recent history marks a large insurgent movement after the fall of fascism, during World War II with Mario Musolesi, better known as Il lupo ("The wolf"), leader of the partisan fraction of Stella Rossa (Red Star).
Brento was a possession of the king and, as such, it was donated by the Lombard king Astulf to the Duke Orso and from the latter to the Abbey of Nonantola. Afterwards it was reintegrated into the possessions of the Bishop of Bologna. After the 11th century the decline of the place commenced. In 1293 the Bishop of Bologna donated the Church of Brento to the fathers of Bologna. In the fourteenth century in Monzuno the Vicariate of the Mountain was active in Monzuno. The community of monks that settled there scattered after 1632. The old Parish Church was destroyed by the events of the war.
The hamlet of Montorio was the centre of a wide Church district long before Monzuno acquired its own administrative right. It was an institution of 42 parishes that were afterwards dismembered. In 1582 Cardinal Gabriele Paleotti established the new Parish of Monzuno. Montorio belonged at first to the local Feudal Lords, then to the Counts Castelli of Bologna. The latter ones donated to the Military Order of S. Stefano di Toscana, in order to take part in it, the Palace of Montorio. The Grand Duke of Tuscany accepted and established the Priorate of Bologna, entrusting its administration to the Castellis. Afterwards the possessions were handed down to the Count Francesco di Thurn di Valsassina, to the Marullis of Bologna and in the end to the Bertis.
