who were very hostile to the idea of a return and had been subject to lots of Tatarophobic propaganda, but for economic reasons: high productivity from Crimean Tatar workers in Central Asia meant that letting the diaspora return would take a toll on Soviet industrialization goals in Central Asia. Historians have long suspected that violent resistance to confinement in exile from Chechens led to further willingness to let them return, while the non-violent Crimean Tatar movement did not lead to any desire for Crimean Tatars to leave Central Asia. In effect, the government was punishing Crimean Tatars for being Stakhanovites while rewarding the deported nations that contributed less to the building of socialism, creating further resentment. A 1967 Soviet decree removed the charges against Crimean Tatars on paper while simultaneously referring to them not by their proper ethnonym but by the euphemism that eventually became standard of "citizens of Tatar nationality who formerly lived in Crimea", angering many Crimean Tatars who realized it meant they were not even seen as Crimean Tatars by the government. In addition, the Soviet government did nothing to facilitate their resettlement in Crimea and to make reparations for lost lives and confiscated property. Before the mass return in the perestroika era, Crimean Tatars made up only 1.5% of Crimea's population, since government entities at all levels took a variety of measures beyond the already-debilitating residence permit system to keep them in Central Asia. Methods The abolition of the special settlement regime made it possible for Crimean Tatar rights activists to mobilize. The primary method of raising grievances with the government was petitioning. Many for the right of return gained over 100,000 signatures; although other methods of protest were occasionally used, the movement remained completely non-violent. When only a small percentage of Crimean Tatars were allowed to return to Crimea, those who were not granted residence permits would return to Crimea and try to live under the radar. However, the lack of a residence permit resulted in a second deportation for them. A last-resort method to avoid a second deportation was self-immolation, famously used by Crimean Tatar national hero Musa Mamut, one of those who moved to Crimea without a residence permit. He doused himself with gasoline and committed self-immolation in front of police trying to deport him on 23 June 1978. Mamut died of severe burns several days later, but expressed no regret for having
