Flag of Aosta Valley

The flag was created in 1942 from an idea by canon Joseph Bréan, who proposed its use in an anti-fascist brochure from 1942 entitled "The Great Aosta Valley". Father Bréan drew the colours of the 16th-century coat of arms of the Duchy of Aosta, a silver lion on a black shield with a red tongue, and a two-colour flag. Shortly afterwards, the resistance movements in the Valle d'Aosta adopted these colours for themselves, creating a flag halved vertically ("per pale"). However after the liberation, this flag was never formally ratified, both because of widespread fear that it might fuel desires for independence and because of its similarity to some banners of the anarchist movement.[2]

The flag was in unofficial use from 1947 until it was officially adopted under the Regional Law of 2006.
