"In this volume I have attempted to explain the psychology of that great movement of impassioned discontent and violent revolution which, because of its rapid development in Russia, and because of the impetus it has received from its terrible pre-eminence in that unfortunate country, we call Bolshevism." John Spargo (1876-1966) was a leading socialist writer of the period.. Spargo, trained as a stonecutter, but became a lay Methodist minister, became identified with the socialists in England in early life, became a leader in the English labor movement; and served on the Executive Council of the Social Democratic Federation. He immigrated to America in 1901 and was thereafter a longtime member of the National Executive Committee of the American Socialist Party. He regarded Bolshevism as an "inverted form of Czarism." He edited the socialist periodical, The Comrade, became involved in child labor issues; helped promote laws on child and woman labor, and moved to Vermont in 1909. He remained active in socialist circles, but moved to the right over World War I, and with Samuel Gompers and George Creel, founded the American Alliance for Labor and Democracy, in favor of American involvement in the war. He gradually became outspoken advocate of free-market capitalism. His major publications include The Bitter Cry of Children (1906) and Karl Marx: His Life and Work (1909).
