The rule of the Popes was interrupted by the short-lived Roman Republic (1798–1800), which was established under the influence of the French Revolution. The Papal States were restored in June 1800, but during Napoleon's reign Rome was annexed as a ''Département'' of the French Empire: first as ''Département du Tibre'' (1808–1810) and then as ''Département Rome'' (1810–1814). After the fall of Napoleon, the Papal States were reconstituted by a decision of the Congress of Vienna of 1814.
