Bund der Gerechten
The GWEA included among its members individuals hailing from several countries and attained a membership of approximately 500 by 1845. In its initial incarnation the GWEA acted as a public arm of the underground revolutionary organisation known as the League of the Just. After 1847 it closely cooperated with the Communist League of Karl Marx, Frederick Engels, and their associates and served in effect as a broader "front" organisation for that more narrow revolutionary group.
