This is Boris Nicolaevsky's amazing booklet The Revolution is not a Masonic Affair - Secret Societies in the First International (1997) which traces the role of under-cover government-persecuted masons in the forming of the First International. In the time of revolutions that have shaken Europe for decades there existed many secret groups that planned to use it for their own purposes. The Lodge of Philadelphians was principally involved, with its heady mixture of pseudo-Egyptian mysticism and leftist politics. However by 1865, tensions arose between these "revolutionary masons" and the emerging force of industrial workers. The principal enemy of the Philadelphians, the man who did most to prevent the First International from becoming a front for their activities, was none other than Karl Marx, the future prophet of communism. The author joined the revolutionary movement of Mensheviks in Russia whilst still at school but was later persecuted by the Bolsheviks and forced to emigrate. This short but fascinating booklet explains how the various groups operated and what were their chief differences providing an unique look into the overall scheme of the revolution itself. 35 pages. A must read for everyone.
