Peace Sign

The Nuclear Disarmament Symbol more commonly known as the Peace Sign was derived from the navy semafore letters N and D, for Nuclear Disarmament. Created by Gerald Holtom in 1958, the symbol was adopted by the Campaign for Nuclear Disarmament (CND), and spread quickly to the USA and around the world during the vietnam war protest period. Various groups have their own interpretations of the symbol, ranging from a death sign, to a droopy Cross of Christ, to eternal disarmament. Some see the center of the symbol as a stick figure with arms drooping in dispair. This stick figure resembles the symbol for "he" in Blissymbolics.

A number of peace symbols have been used in various cultures and contexts, one of the most ancient being the olive branch. The symbol of the dove and olive branch was used by early Christians and was later adopted as a secular symbol. It was popularised by Pablo Picasso in 1949 and became widely used in the post-war peace movement. In the 20th century the peace sign was adopted by the Campaign for Nuclear Disarmament.
