German Workers Educational Association
The German Workers Educational Association (GWEA or DABV; German: Deutscher Arbeiterbildungsverein) was a London-based organisation of radical German political émigrés established in 1840 by Karl Schapper and his associates. The organisation served during its initial years as the "above-ground" arm of the underground League of the Just and later as a mass organisation of the Communist League.
