MAR 21 - Friday was a holy 50 years ago when was born in London, when a march against nuclear war, the symbol of peace. The emblem of the protest that would become one of the most 'recognizable to the world. Since then, and was adapted, distorted, marketed and demonized, but keeps intact all his affidavit' and symbolic power. The new symbol through the Atlantic, becoming the symbol of pacifist protest against the war in Vietnam.

The symbol of peace was born as a symbol of English Campaign for Nuclear Disarmament (Campaign for Nuclear Disarmament (CND)) and was designed by Gerald Holtom in 1958 starting with the letters N and D as represented by the code of signals with flags:

The frequent failure to assign paternity Bertrand Russell probably derives from the fact that Russell was the chairman of CND at that time.

The first public use of the symbol dates from the Aldermaston march in England during 1958, as described in an article on the event by the Manchester Guardian.

Nearly 10 years after the symbol begins to be used as a general reference to the Peace student movement against the war, becoming probably the best known symbol of youth culture of the sixties.

A slightly different interpretation is as follows. The vertical line is the signal flags with the letter D stands for "disarmament", the two lines are inclined to the letter N, which stands for "nuclear" while the circle represents the word "global". So what is Global Nuclear Disarmament.

According to some symbol derives from two historic Christian symbols: the outer circle indicates the earth (desolate and empty, Gen 1:2) while the interior design "witch foot / paw of crow", "GOD down" (with the gift salvation, John 3:16).

According to the other two arms with flags, without the circle, to resemble a stylized figure with open arms - "the act of a desperate human being", the circle represents the uterus or not born generations, as well as the world; black represents eternity.

Another explanation, presumably "unofficial", is that it represents the cross of Christ with arms lowered as a sign of desperation. In fact, it is also the symbol of Death v Runa Runic Futhark.

With ownership of the symbol by the pacifist movements in the'60s, Christians not traditionalists and fundamentalists (who apparently did not know anything symbols Christians) have added a satanic significance, calling the Witch foot, or Zampa of Corvus ( Zampa times of Chicken) or tail broken

During the'80s, the symbol is used, at least in the United States, to represent the environment, particularly in the form of imitation of the American flag as blue and green with the peace symbol instead of stars.

Currently, the color and size vary widely, most often is the white symbol in black, but other combinations are white on blue, green and pink and white on black, and the proportions are more common 3:5.
