The Roman Republic is proclaimed after Louis-Alexandre Berthier, a general of Napoleon, had invaded the city of Rome five days earlier.

The Roman Republic was a sister republic of the First French Republic that existed from 1798 to 1799. It was proclaimed on 15 February 1798 after Louis-Alexandre Berthier, a general of the French Revolutionary Army, had occupied the city of Rome on 11 February. It was led by a Directory of five men and comprised territory conquered from the Papal States. The Roman Republic immediately incorporated two other former-papal revolutionary administrations, the Tiberina Republic and the Anconine Republic. It proved short-lived, as Neapolitan troops restored the Papal States in October 1799.
