Glasnost () was a policy that called for increased openness in government institutions and activities in the Soviet Union. It was introduced by Mikhail Gorbachev in the second half of the 1980s. Glasnost is often paired with Perestroika (restructuring), another reform instituted by Gorbachev at the same time. The word "glasnost" has been used in Russian at least since the end of the 18th century.
