World history of the 20th century, as well as the history of modern Russia, cannot be fully understood without knowledge of the political views and practical activities of Mikhail Sergeevich Gorbachev. Having initiated Perestroika in the Soviet Union, making a huge contribution to the end of the Cold War, he became one of the most prominent political leaders of the 20th century.
