Rather than listing the republics in alphabetical order, the republics were listed in constitutional order, which, particularly by the last decades of the Soviet Union, did not correspond to order either by population or economic power. The Turkestan Soviet Federative Republic was proclaimed in 1918 but did not survive to the founding of the USSR, becoming the short-lived Turkestan Autonomous Soviet Socialist Republic of the RSFSR. The Crimean Soviet Socialist Republic (Soviet Socialist Republic of Taurida) was also proclaimed in 1918, but did not became a union republic and was made into an autonomous republic of the RSFSR, although the Crimean Tatars had a relative majority until the 1930s or 1940s according to censuses. When the Tuvan People's Republic joined the Soviet Union in 1944, it did not become a union republic, and was instead established as an autonomous republic of the RSFSR. The leader of the People's Republic of Bulgaria, Todor Zhivkov, suggested in the early 1960s that the country should become a union republic, but the offer was rejected. During the Soviet–Afghan War, the Soviet Union proposed to annex Northern Afghanistan as its 16th union republic in what was to become the Afghan Soviet Socialist Republic. Several of the Union Republics themselves, most notably Russia, were further subdivided into Autonomous Soviet Socialist Republics (ASSRs). Though administratively part of their respective Union Republics, ASSRs were also established based on ethnic/cultural lines. Under Mikhail Gorbachev, "glasnost" ("openness") and "perestroika" ("restructuring") were intended to liberalise and open up the Soviet Union. However, they had a number of effects which caused the power of the republics to increase. First, political liberalization allowed the governments within the republics to gain legitimacy by invoking democracy, nationalism, or a combination of both. In addition, liberalization led to fractures within the Communist Party which resulted in reduced ability to govern the Union effectively. The rise of nationalist and right-wing movements, notably led in Russia by Boris Yeltsin, in the previously homogeneously Communist political system led to the crumbling of the Union's foundations. With the central role of the Communist Party removed from the constitution, the Communist Party lost its control over the political system and was banned from operating after an attempted coup d'état. Throughout the unravelling of the restructuring, the Soviet government attempted to find a new structure which would reflect the increased power of the republics.
