was the Soviet leader that was installed as chairman of the Soviet Communist Party in March 1985. He was amicable, energetic, and most of all committed to reforming the Soviet Union. He championed two policies: glasnost and perestroika. These measures would promote "openness" and "restructuring" of the economy. These measures, however, required that the Cold War be put to an end. His cooperation with Ronald Reagan has earned the two leaders great praises.
