Such misapplications of the linguistic equivalents to the term ''Russia'' and its derivatives were frequent in other languages as well.

in Lithuania, that country declared its independence restored on 11 March 1990. A referendum for the preservation of the USSR was held on 17 March 1991 in nine republics (the remainder having boycotted the vote), with the majority of the population in those republics voting for preservation of the Union. The referendum gave Gorbachev a minor boost. In the summer of 1991, the

—an attempted coup d'état by hardline members of the government and the KGB who sought to reverse Gorbachev's reforms and reassert the central government's control over the republics. After the coup collapsed, Yeltsin was seen as a hero for his decisive actions, while Gorbachev's power was effectively ended. The balance of power tipped significantly towards the republics. In August 1991, Latvia and Estonia immediately declared the restoration of their full independence (following Lithuania's 1990 example). Gorbachev resigned as general secretary in late August, and soon afterwards, the party's activities were indefinitely suspended—effectively ending its rule. By the fall, Gorbachev could no longer influence events outside Moscow, and he was being challenged even there by Yeltsin, who had been elected

Data shows Russia, Kazakhstan, Latvia, Lithuania and Estonia saw a tripling of unemployment and a 42% increase in male death rates between 1991 and 1994. In the following decades, only five or six of the post-communist states are on a path to joining the wealthy capitalist West while most are falling behind, some to such an extent that it will take over fifty years to catch up to where they were before the fall of the Soviet Bloc.
