Works & Achievements
As a member of the Roman Curia, Vincenti-Mareri sat on various pontifical congregations responsible for managing the affairs of the universal Church — ecclesiastical discipline, relations with sovereign states, doctrinal matters, and canonical disputes.
His participation in this extraordinary conclave, held outside Rome on Habsburg territory following the captivity of Pius VI, contributed to the election of Pius VII and to preserving the institutional continuity of the papacy at the height of the revolutionary crisis.
Under Pius VII, he continued his administrative work within the Curia, taking part in the gradual implementation of the Concordat of 1801 and in defending the temporal rights of the Holy See against Napoleonic encroachments on the Papal States.
Anecdotes
In 1798, when French troops invaded Rome and proclaimed the Roman Republic, Cardinal Vincenti-Mareri had to make the difficult decision — as did many members of the Curia — whether to remain in the Eternal City or flee. This occupation profoundly disrupted the organization of the Catholic Church and forced its prelates to navigate between loyalty to the Holy See and political pragmatism in the face of the revolutionary occupiers.
The death of Pope Pius VI in captivity at Valence in 1799 plunged the Roman Curia into an unprecedented crisis. Vincenti-Mareri took part in the deliberations that led to the organization of the Conclave of Venice (1799–1800), an extraordinary event held outside Rome for the first time in centuries, under Habsburg protection, which ultimately elected Pius VII.
During the pontificate of Pius VII, Vincenti-Mareri witnessed the complex negotiations surrounding the Concordat of 1801 between Napoleon and the Holy See. This treaty, which reorganized the Church in France after the devastation of the Revolution, was hailed by some as a diplomatic victory and criticized by others as a capitulation to Bonapartist power.
In 1809, when Napoleon annexed the Papal States and had Pius VII arrested, the cardinals who refused to swear allegiance to the Empire were branded "black cardinals" as a mark of imperial disgrace. Vincenti-Mareri, then in the final years of his life, lived through the painful humiliation of a Church whose temporal head was a prisoner of an emperor.
