how did the policies introduced by Mikhail Gorbachev, including perestroika and glasnost lead to the collapse of the Soviet Union

Gorbachev came to power at a time when the Soviet Union was experiencing a deep slump. The country was engaged in a hopeless struggle in Afghanistan, military expenditure was very high, domestic troubles threatened because of the bad economic situation. Everything citizens needed for everyday life was lacking, there was a huge government deficit. The industry was very outdated and the party's moral authority had fallen to zero. In addition, under the leadership of Ronald Reagan, the US had surpassed the USSR militarily and built on its lead.

Gorbachev realized that it could no longer continue and that the country was about to collapse. To keep the Soviet Union and communism alive, reforms were inevitable. His predecessor Yuri Andropov, who had brought him to Moscow, already wanted to make changes, but was too often ill to start. Konstantin Chernenko, who succeeded Andropov, was also too ill to do much. Gorbachev decided to change the course. He expected that by giving people more initiative, they would generate more economic prosperity so that the state as a whole would benefit.

Gorbachev ruled with the slogan "uskorenie" (economic intensification), "glasnost" (openness) and "perestroika" (reform) and introduced "new thinking" in foreign policy. More and more far-reaching treaties to relax world politics were concluded with the West. But a less desirable outcome, at least for the Communist Party, was that latent nationalism emerged in the federated states of the union.

Later it turned out that Gorbachev had released forces that he soon could no longer control. The party bosses in the states, who began to put their cards on the advancing nationalism, soon began to become increasingly independent of the central authority in Moscow. Despite his (late) attempts to crack down on the independence movements in the various republics (especially the Baltic) with great force, a process had started that could no longer be stopped; except perhaps with massive and ruthless military intervention.

In August 1991, Old Guard communists attempted to reverse the increasingly out of control consequences of Gorbachev's policy with a coup attempt, but it failed and paved the way for the rise of Boris Yeltsin, the newly elected President of the Russian Federation, who performed prominently during these events. Gorbachev was restored as leader of the Soviet Union, but he was now completely outflanked by Boris Yeltsin. Soon, practically all the republics of the Union declared their independence, and behind Gorbachev's back, the CIS was established, replacing the old Soviet Union. The Soviet Union was officially dissolved in December 1991, ending Gorbachev's rule.

The changing dynamics created by the Mikhail Gorbachev, including perestroika and glasnost unsettled the forces which led to weakening the Soviet Union and its demolishment in 1989.

Explanation:

In 1985, even many of the most conservative hardliners realized that much needed to change. The Soviet economy was faltering and dissidents and internal and external critics were calling for an end to political repression and government secrecy.

Shortly after taking power, Gorbachev tried to tackle these challenges. Under a new policy of glasnost, or transparency and openness, new press freedoms shone a light on many of the most negative aspects of the Soviet Union, both past and present. And with perestroika, the Soviet Union would undergo a rapid political and economic restructuring that aimed to transform much of society.

While the reforms of glasnost and perestroika were not the sole causes of the dissolution of the U. S. S. R., the forces they unleashed destabilized an already weakening system and hastened its end.
