How did glasnost and perestroika encourage Latvia’s national renaissance in the late 1980s?

In the late 1980s, the Soviet policies of glasnost ("openness") and perestroika (economic and political restructuring) initiated by Mikhail Gorbachev fundamentally altered the political landscape in the Baltic states. By weakening the central power structure in Moscow, these reforms provided the necessary space for Latvia to assert its autonomy and pursue a national renaissance.12

This environment allowed for the emergence of the first nonofficial political organizations and mass movements, such as the Helsinki-86 group, which advocated for human rights, and the Environmental Protection Club. In 1987, mass demonstrations regarding ecological issues marked the first unofficial political gatherings in postwar Latvia. By 1988, the Popular Front of Latvia had emerged, channeling this growing national sentiment into a formal movement that eventually led to the reestablishment of Latvian independence.1324
