The so-called Tiberina Republic was a revolutionary municipality proclaimed on 4 February 1798, when republicans took power in the city of Perugia. It was an occupation zone that took its name from the river Tiber. A month later, the government of all the Papal States was changed into a republic: the Roman Republic, which Perugia belonged to. Its head was a consul and it used a tricolor similar to the French flag.
