During the Napoleonic era, in 1797, the first official adoption of the Italian tricolour as a national flag by a sovereign Italian state, the Cispadane Republic, a Napoleonic sister republic of Revolutionary France, took place, on the basis of the events following the French Revolution (1789–1799) which, among its ideals, advocated the national self-determination. This event is celebrated by the Tricolour Day. The Italian national colours appeared for the first time on a tricolour cockade in 1789, anticipating by seven years the first green, white and red Italian military war flag, which was adopted by the Lombard Legion in 1796.
