Candidate passages:
Glasnost (, , lit.
"publicity") was a policy that called for increased openness and transparency in government institutions and activities in the Soviet Union.
Introduced by Mikhail Gorbachev in the second half of the 1980s, Glasnost is often paired with Perestroika (literally: Restructuring), another reform instituted by Gorbachev at the same time.
The word "glasnost" has been used in Russian at least since the end of the 18th century.
The word was frequently used by Gorbachev to specify the policies he believed might help reduce the corruption at the top of the Communist Party and the Soviet government and moderate the abuse of administrative power in the Central Committee.
Russian human rights activist and dissident Lyudmila Alexeyeva explained "glasnost" as a word that "had been in the Russian language for centuries.
It was in the dictionaries and lawbooks as long as there had been dictionaries and lawbooks.
It was an ordinary, hardworking, nondescript word that was used to refer to a process, any process of justice of governance, being conducted in the open.
"Glasnost can also refer to the specific period in the history of the USSR during the 1980s when there was less censorship and greater freedom of information. 
Final years (1985–91).
Gorbachev reforms.
By the time the comparatively youthful Mikhail Gorbachev became General Secretary in 1985, the Soviet economy was stagnant and faced a sharp fall in foreign currency earnings as a result of the downward slide in oil prices in the 1980s.
These issues prompted Gorbachev to investigate measures to revive the ailing state.
An ineffectual start led to the conclusion that deeper structural changes were necessary and in June 1987 Gorbachev announced an agenda of economic reform called "perestroika", or restructuring.
Perestroika relaxed the production quota system, allowed private ownership of businesses and paved the way for foreign investment.
These measures were intended to redirect the country's resources from costly Cold War military commitments to more productive areas in the civilian sector.
Despite initial skepticism in the West, the new Soviet leader proved to be committed to reversing the Soviet Union's deteriorating economic condition instead of continuing the arms race with the West.
Partly as a way to fight off internal opposition from party cliques to his reforms, Gorbachev simultaneously introduced "glasnost", or openness, which increased freedom of the press and the transparency of state institutions.
"Glasnost" was intended to reduce the corruption at the top of the Communist Party and moderate the abuse of power in the Central Committee.
Glasnost also enabled increased contact between Soviet citizens and the western world, particularly with the United States, contributing to the accelerating détente between the two nations.
In the USSR itself, "glasnost" weakened the bonds that held the Soviet Union together and by February 1990, with the dissolution of the USSR looming, the Communist Party was forced to surrender its 73-year-old monopoly on state power.
At the same time freedom of press and dissent allowed by "glasnost" and the festering "nationalities question" increasingly led the Union's component republics to declare their autonomy from Moscow, with the Baltic states withdrawing from the Union entirely. 
Mikhail Gorbachev was the Party's first leader to have been born after the Revolution.
As de facto ruler of the USSR, he tried to reform the stagnating Party and the state economy by introducing "glasnost" ("openness"), "perestroika" ("restructuring"), "demokratizatsiya" ("democratization"), and "uskoreniye" ("acceleration" of economic development), which were launched at the 27th Congress of the CPSU in February 1986. 
Gorbachev's policy interpretation of "glasnost" can best be summarized, translated, and explained in English with one word: "openness."
While "glasnost" is associated with freedom of speech, the main goal of this policy was to make the country's management transparent and open to debate, thus circumventing the narrow circle of apparatchiks who previously exercised complete control of the economy.
Through reviewing the past or by opening up the censored literature in the libraries and a greater freedom of speech: a radical change, as control of speech and suppression of government criticism had previously been a central part of the Soviet system.
There was also a greater degree of freedom within the media.
In the late 1980s, the Soviet government came under increased criticism, as did Leninist ideology (which Gorbachev had attempted to preserve as the foundation for reform), and members of the Soviet population were more outspoken in their view that the Soviet government had become a failure.
Glasnost did indeed provide freedom of expression, far beyond what Gorbachev had intended, and changed citizens' views towards the government, which played a key role in the demise of the Soviet Union.
