This rainbow flag in Italy was first used in a peace march in 1961, inspired by similar multi-coloured flags used in demonstrations against nuclear weapons. It became popular with the Pace da tutti i balconi ("peace from every balcony") campaign in 2002, started as a protest against the impending war in Iraq. The most common variety has seven colours, purple, blue, azure, green, yellow, orange and red, and is emblazoned in bold with the Italian word PACE, meaning "peace".
Common variations include moving the purple stripe down below the azure one, and adding a white stripe on top (the original flag from the 60s had a white stripe on top). This flag has been adopted internationally as a symbol of the peace movement.
