Hello!
Mikhail Gorbachev was the last soviet leader. He had the control of the Soviet Union between 1985 and 1991 and started two great reforms:
The perestroika: economics measures to recover the Soviet Union. For example: reduced the investments in military and opened the market gradually.
The glasnost: the "freedom of speech" and government transparency to the people.
