Under Soviet rule there was a famine followed by progressive decline of the Tatar language, culture and religion both Christian and Muslim. The discovery of large petroleum deposits helped to promote further major growth in industry. Around the time of the fall of the USSR in 1991 there were again moves for independence, but in 1994 the region, under the name of Tatarstan, became a constituent republic of the Russian Federation. In 2008 a national assembly, the "Milli Mejlis", declared Tatarstan independent, but this status has not been recognised by the United Nations or the Russian government.
