1. CND Campaign for Nuclear Disarmament Organization Logo

Originally the logo of the British Campaign for Nuclear Disarmament (CND), consisting of the naval flag signals "N" and "D" Composed, happens to be the first letters of the English word that stands for nuclear disarmament.

2. Anti-war peace symbol

First appeared in 1958, when the Soviet Union and the United States were engaged in a nuclear weapons race during the Cold War. At the same time, a private anti-arms race movement began to quietly gather strength in Britain. Early that year, a group called the Direct Action Campaign was formed and began planning a large-scale anti-war march. Subsequently, the Campaign for Nuclear Disarmament (CND), also based in the UK, also joined in. In their plan, the anti-war march route was 84 kilometers from London to a village called Aldermaston. Aldermaston was chosen because it was the location of the Atomic Weapons Institute, Britain's nuclear weapons research center at the time.

One member of this group was the commercial artist Gerald Halton, who became a staunch anti-war activist during World War II. Entrusted by the organization, he used the signals in the naval flag as design elements and designed the peace and anti-war symbol that later became popular all over the world. In the naval flag, the signalman holds two flags, which are pointed downward at a 45-degree angle to represent "N". One of the two flags is pointing upward and the other is pointing downward to represent "D". "N" and "D" are " "Nuclear disarmament" is the acronym for the English word "nuclear disarmament". Holton combined the two into simple lines and drew a circle outside.

From the beginning, it was just an abbreviation for "nuclear disarmament", and later became a symbol used by all peace movements. The hippies played a major role in the development and promotion of anti-war symbols. During the Vietnam War, anti-war symbols were widely used in various peaceful rallies and movements. Later, even some environmental organizations such as Greenpeace began to use this symbol in their actions to protect the environment.
