During the persecution and prohibition of Freemasonry by the Nazi regime of Hitler, the freemasons continued to meet and celebrate their rituals in secret.
The square and the compass was not a good symbol to use at that time. So, to be able to recognize each other, the little blue flower "Do not Forget Me" was chosen as a Masonic emblem.
The Grossloge Zur Sonne (The Grand Lodge of the Sun) needed a more discreet symbol than the Square and the Compass to identify its Members. Throughout the Nazi era, a small blue flower on the lapel identified a Mason In the Concentration camps and in cities, that little blue flower do not forget me identified those who refused to let the Light of Freemasonry go extinct. Thus it was that a small and insignificant little blue flower became a significant emblem of the Order, becoming perhaps the emblem most used by the German Freemasons.
By an extraordinary coincidence, the pin used by the Nazis for the collection of the winter of 1938, was the same Do not Forget Me chosen by the Masons in 1926 that after the Collection could not be used by Masons to use a brand or emblem that does not had been distributed by the Party constituted a criminal offense during the Nazi regime.
In 1948 the United Grand Lodge of Germany of AL. and AM. at its 1st Annual Convention. Adopted that the flower called Do not forget me (Blue forget me not) constituted a Masonic symbol, in memory of those who have suffered in the name of universal Freemasonry.
