The Tri-coloured standard
The Italian flag was created in Reggio Emilia on 7 January 1797 when, on the proposal of Deputy Giuseppe Compagnoni, the Parliament of the Cispadana Republic decreed universal use of the tri-coloured Cisalpina flag (white, green and red, the revolutionary and Napoleonic colours, also associated over the centuries with many local northern governments). Shortly afterward Napoleon completed his conquest of the peninsula and the many Jacobean republics that he left behind, although eliminated by the short-lived Austrian Restoration, gave decisive impetus to the flag being understood no longer as a dynastic or military standard but as a symbol of the people, of liberty achieved and, therefore, of the nation itself. And so, having been suppressed by the Vienna Congress, the Tricolour came back to wave over the movements of 1831 and after 1848, became the unequivocal symbol for the nation's redemption, accomplished before the first war of independence by Charles Albert of the House of Savoy (although alongside the Savoy family crest), and remaining in use up to the proclamation of the Kingdom of Italy on 14 March 1861.
