League of the Just
In 1839, the League participated in an insurrection carried out by the 'Society of the Seasons', led by Armand Barbès and Auguste Blanqui. The insurrection was suppressed and Moll escaped to Britain. In 1840 he was one of the founders of the German Workers' Educational Association in London. In 1846 he became a member of the Central Committee of the League of the Just (which had been relocated to London). Under the influence of Karl Marx, who replaced Weitling as the ideological leader of the group, the League was re-organised as the 'Communist League'. Moll was again elected to its Central Committee.
