In 1834 he joined the secret society 'Young Germany' in Switzerland. Modelled on Mazzini's 'Young Italy', it advocated a similar mixture of democratic democracy, nationalism and social reform. His friendship with the labour organiser and revolutionary Karl Schapper dated from that period. In 1836, Moll was expelled from Switzerland and went to Paris, where he joined the 'League of the Just', then under the influence of the utopian communist Wilhelm Weitling. Schapper was also a member.
