Mikhail Gorbachev was the final leader of the Soviet Union, serving from 1985 until its dissolution in 1991. His leadership marked a significant shift in Soviet politics and policies, particularly through his initiatives of glasnost (openness) and perestroika (restructuring), which aimed to reform the stagnant Soviet economy and increase transparency in government. These changes played a crucial role in the end of the Cold War, as they encouraged greater freedom and ultimately contributed to the collapse of the Soviet Union.
