The 'Donation of Constantine' (
Latin, ''Constitutum Donatio Constantini'' or ''Constitutum domini Constantini imperatoris'') is a forged Roman imperial edict devised probably between
750 and
850. The precise purpose of the forgery is not entirely certain, but it was clearly a defense of papal interests, perhaps against the claims of either the
Byzantine Empire, or the Frankish king
Charlemagne, who had assumed the former imperial dignity in the West and with it the title "Emperor of the Romans". The earliest date is the most probable, and it is often said that the document could have been written during the papacy of
Stephen II, around
752. The ''Donation'' is included among the texts of the ''
False Decretals of Isidore''.
Origin and content
Purportedly issued by the fourth century
Roman Emperor Constantine I, the Donation grants
Pope Sylvester I and his successors, as inheritors of
St. Peter, the dominion over the city of
Rome,
Italy, and the entire
Western Roman Empire, while Constantine would retain imperial authority in the
Eastern Roman Empire from his new imperial
capital of
Constantinople. The text claims that the Donation was Constantine's reward to Sylvester for instructing him in the Christian faith, baptizing him and miraculously curing him of
leprosy.
It has been suggested that an early draft was made shortly after the middle of the eighth century in order to assist
Pope Stephen II in his negotiations with
Pepin the Short, the Frankish Mayor of the Palace. In 754, Pope Stephen II crossed the Alps to anoint Pepin king, thereby enabling the Carolingian family to supplant the old Merovingian royal line. In return for Stephen's support, Pepin apparently gave the Pope the lands in Italy which the Lombards had taken from the Byzantine Empire. These lands would become the
Papal States and would be the basis of the Papacy's secular power for the next eleven centuries.
Medieval use
Inserted among the twelfth-century compilation known as the
Decretum Gratiani, this document continued to be used by medieval popes to bolster their claims for territorial and secular power in Italy. It was widely accepted as authentic, although the Emperor
Otto III denounced the document as a forgery. The poet
Dante Alighieri lamented it as the root of papal worldliness in his
Divine Comedy. However, by the mid 15th-century, with the revival of Classical scholarship and textual critique, the Church had begun to realize that the document could not possibly be genuine.
Investigation
The Italian
humanist Lorenzo Valla proved in
1440, in his treatise ''De falso credita et ementita Constantini donatione'', that the Donation must be a fake by analyzing its
language, and showing that while certain imperial-era formulas are used in the text, some of the Latin in the document could not have been written in the fourth century; anachronistic terms such as "
fief" were used. Also, the purported date of the document is inconsistent with the content of the document itself as it refers both to the fourth consulate of Constantine (315) as well as the consulate of Gallicanus (317).
More recently, scholars have further demonstrated that other elements, such as Sylvester's curing of Constantine, are legends which originated at a later time. Its recent editor
[1] has affirmed that at the time of the composition of Valla's work, Constantine's alleged "donation" was no longer a matter of contemporary relevance in
political theory and that, rather, it furnished the theme for a brilliant exercise in legal rhetoric.
Contemporary opponents of papal powers in the Peninsula emphasized the primacy of civil law and civil jurisdiction, now firmly embodied once again in the Justinian ''
Corpus Juris Civilis''. The Florentine chronicler
Giovanni Cavalcanti reported that, in the very year of Valla's treatise,
Filippo Maria Visconti, duke of Milan, made diplomatic overtures toward
Cosimo de' Medici in Florence proposing an alliance in common defence against the Pope, as sovereign lord of the
Marche, where
Francesco Sforza was currently protected by papal sovereignty, in which Visconti used the words, "It so happens that even if Constantine consigned to Sylvester so many and such rich gifts— which is doubtful, because such a privilege can nowhere be found— he could only have granted them for his lifetime: the Empire takes precedence over any lordship."
Civil law was the Emperor's prerogative, according to the Imperial vassal Visconti: "and for this reason you see why the Church is without civil law."
[2] Valla's refutation was taken up vehemently by scholars of the
Protestant Reformation, such as
Ulrich von Hutten and
Martin Luther.
