The peace sign, also known as the peace symbol, is a widely recognized emblem representing peace and anti-war movements. It was designed in 1958 for the British nuclear disarmament movement by Gerald Holtom. The symbol combines the semaphore signals for the letters "N" and "D," standing for "nuclear disarmament." Over the years, the peace sign has become a universal symbol of non-violence and harmony. It is often associated with the 1960s counterculture, including the hippie movement, and is frequently used in protests and demonstrations advocating for peace and social justice.
