eastern part of Russia to Siberia. After the war, the remaining Russian Mennonites were branded as Nazi conspirators and exiled to Kazakhstan and Siberia, sometimes being imprisoned or forced to work in concentration camps. In the 1990s the Russian government gave the Mennonites in Kazakhstan and Siberia the opportunity to emigrate. Policy towards Islam Soviet policy toward Islam was affected, on the one hand by the large Muslim population, its close ties to national cultures, and its tendency to accept Soviet authority, and on the other hand by its susceptibility to foreign influence. Although actively encouraging atheism, Soviet authorities permitted some limited religious activity in all the Muslim republics, under the auspices of the regional branches of the Spiritual Administration of the Muslims of Central Asia and Kazakhstan. Mosques functioned in most large cities of the Central Asian republics, the Caucasus, Tatarstan, Bashkortostan, Crimea, the Azerbaijan Republic, and elsewhere, but their number decreased from 25,000 in 1917 to 500 in the 1970s. Under Stalinist rule, Soviet authorities cracked down on Muslim clergy, closing many mosques or turning them into warehouses. In 1989, as part of the general relaxation of restrictions on religions, some additional Muslim religious associations were registered, and some of the mosques that had been closed by the government were returned to Muslim communities. The government also announced plans to permit the training of limited numbers of Muslim religious leaders in two- and five-year courses in Ufa and Baku, respectively. Policy towards Judaism Lenin publicly condemned anti-Semitism, the government however was hostile toward Judaism from the beginning. In 1919 the Soviet authorities abolished Jewish community councils, which were traditionally responsible for maintaining synagogues. They created a special Jewish section of the party, whose tasks included propaganda against Jewish clergy and religion. To offset Jewish national and religious aspirations, and to reflect the Jewish national movement's role in the socialist movement of the Russian Empire (for example, Trotsky was first a member of the Jewish Bund, not the Social Democratic Labour Party), an alternative to the Land of Israel was established in 1934. The Jewish Autonomous Oblast, created in 1928 by Stalin, with Birobidzhan in the Russian Far East as its administrative center, was to become a "Soviet Zion". Yiddish, rather than "reactionary" Hebrew, would be the national language, and proletarian socialist literature and arts would replace Judaism as the quintessence of its culture.
