Why does Italy have two flags?
The Kingdom of Italy was proclaimed on 17 March, 1861, and its flag continued to be the one that was customary prior to the war of independence. However, the lack of an ad hoc law on the national flag, which instead only concerned military banners, led to the development of several variants, which were often arbitrary. The national flag of Italy, often referred to as the Tricolour (il Tricolore, Italian: [il trikoˈloːre]), is a flag featuring three equally sized vertical pales of green, white and red, with the green at the hoist side, as defined by Article 12 of the Constitution of the Italian Republic.
