Following the collapse of the Soviet Union in 1991, Gorbachev remained in domestic politics, as well as making regular appearances on Russian and global media. He also established a foundation for economic, political and social research.

One of the great statesmen of the twentieth century, Gorbachev is the last of the political triumvirate who, along with Thatcher and Reagan, presided over the dénouement of the Cold War.
