Flag of Italy [SEP] Meaning of colours
During the Napoleonic period, the three colours acquired a more idealistic meaning for the population: the green represents hope, the white represents faith and the red represents love. Other less probable conjectures that explain the adoption of the green hypothesize a tribute that Napoleon wanted to give to Corsica, where he was born, or to a possible reference to the verdant Italian landscape. For the adoption of greenery there is also the so-called "Masonic hypothesis": even for Freemasonry, green was the colour of nature, a symbol of human rights, which are naturally inherent in the human being, as much as of the florid Italian landscape; this interpretation, however, is opposed by those who maintain that Freemasonry, as a secret society, did not have such an influence at the time that inspired Italian national colours.
