Young Italy (Italian: La Giovine Italia) was a political movement for Italian youth (under age 40) founded in 1831 by Giuseppe Mazzini. After a few months of leaving Italy, in June 1831, Mazzini wrote a letter to King Charles Albert of Sardinia, in which he asked him to unite Italy and lead the nation. A month later, convinced that his demands did not reach the king, he founded the movement in Marseille. It would then spread out to other nations across Europe.[1] The movement's goal was to create a united Italian republic through promoting a general insurrection in the Italian reactionary states and in the lands occupied by the Austrian Empire. Mazzini's belief was that a popular uprising would create a unified Italy.[2] The slogan that defined the movement's aim was "Union, Strength, and Liberty". The phrase could be found in the tricolor Italian flag, which represented the country's unity.[3]
