Gorbatschow

Mikhail Gorbachev was the last leader of the Soviet Union, known for his reforms of glasnost (openness) and perestroika (restructuring), which aimed to modernize the Soviet economy and society. His policies contributed to the end of the Cold War and the dissolution of the Soviet Union in 1991. Gorbachev's efforts to promote peace and international cooperation, particularly in reducing nuclear weapons, earned him the Nobel Peace Prize in 1990.
