The United provinces of Italy lasted for 2 months and the United provinces of Central Italy - as you can see lasted for about a year. The Official Flag Of The Kingdom Of Italy - Regno d’Italia is the green,white,red with the Savoy shield. All these flags you posted here are republics that existed before the unification in 1861 under the crown of Victor Emanuel II. As for the voices and representation there is a more in-depth topic and i didnt want to repeat the guy’s words. Just mentioned it as an issue and offered a fix.
