that such data should not, as a principle, be used. Another such anecdote can be found in the 1929 Moscow religion survey, in which 12,000 industrial workers were surveyed anonymously and only 3,000 returned the survey, of which 88.8% claimed to be atheists, and it was then declared that 90% of Moscow industrial workers were atheists. The non-serial LMG literature grew from 12 million printed pages in 1927 to 800 million in 1930 (making up at least 100 million pieces of printed antireligious literature). In 1941 sixty-seven books and brochures of antireligious propaganda were printed with a total circulation of 3.5 million copies. Up to 1940 there were about 2000 titles published every year. A textbook produced by the LMG in 1934 admitted the existence of sincere believers among the intellectuals; however, Yaroslavsky in 1937 claimed that all scholars and scientists who believe in God were insincere deceivers and swindlers. The League trained a massive number of antireligious propagandists and other workers. This work included lecture cycles. The League of Militant Atheists attempted to "control and exploit the Proletarian Freethinkers," a group founded by socialists in 1925, in order to diminish the influence of religion, particularly Catholic Christianity, in Central and Eastern Europe. The League of Militant Atheists aided the Soviet government in killing clergy and committed believers. The League also made it a priority to remove religious icons from the homes of believers. Under the slogan, "the Storming of Heaven," the League of Militant Atheists pressed for "resolute action against religious peasants" leading to the mass arrest and exile of many believers, especially village priests. By 1940, "over 100 bishops, tens of thousands of Orthodox clergy, and thousands of monks and lay believers had been killed or had died in Soviet prisons and the Gulag." The LMG had reduced the number of religious communities of all faiths from 50,000 in 1930 to 30,000 by 1938 and 8,000 by 1941. The last figure includes, however, 7,000 communities in the annexed western territories (so that only 1,000 actually remained in the rest of the country). Disbandment The climate of the campaign against religion was changing in the late 1930s and early 1940s. The regime slowly became more moderate in its approach to religion. Yaroslavsky, in 1941 warned against condemning all religious believers, but said that there were many loyal Soviet citizens still possessing religious beliefs. He called for patient and tactful
