Pepin the Short: From Real Power to the Crown (741–768) · EARLY MIDDLE AGES
The alliance between Pepin the Short and the papacy is not limited to a ceremony: it durably changes the political map of the West. Between 753 and 756, the Frankish kingdom becomes the main military protector of Rome.
In the 8th century, the papacy is caught between two realities:
Faced with this deadlock, Pope Stephen II crosses the Alps in 753. It is an exceptional move: he comes to seek direct support from a western ruler.
The strength of this alliance is simple: the pope brings sacred legitimacy, Pepin brings military protection.
The promise becomes action. Pepin intervenes in Italy against Aistulf, then returns when agreements prove insufficient. The campaigns of 755 and 756 constrain the Lombard king and lead to territorial restitutions in favour of the pope.
The “Donation of Pepin” refers to the set of commitments and restitutions that give the pope a territorial base in Italy. The core concerns former Byzantine territories taken by the Lombards, around the Exarchate of Ravenna and the Pentapolis.
The change is major:
Detailed lists of promised territories vary by texts and reconstructions; it is better to retain the idea of an Italian core (Ravenna and surroundings) than a fixed inventory.
Confirmation and expansion continue, notably with Charlemagne (confirmation in 774).
