One of the changes that ensued was the establishment in 1943 of an officially sanctioned Islamic hierarchy for Central Asia, the Muslim Board of Central Asia. Together with three similar organizations for other regions of the Soviet Union having large Muslim populations, this administration was controlled by the Kremlin, which required loyalty from religious officials. Although its administrative personnel and structure were inadequate to serve the needs of the Muslim population of the region, the administration made possible the legal existence of some Islamic institutions, as well as the activities of religious functionaries, a small number of mosques, and religious instruction at two seminaries in Uzbekistan.[citation needed]
