"The movement that mobilized to oppose Alyaksandr Lukashenka in August 2020 was notable for its ability to bridge divisions of social class, geography, age, and identity. Almost uniquely among post-Soviet revolutionary movements, the Belarusians who rose up were not divided from those who did not along clearly discernible sociodemographic, ethnic, linguistic, or regional lines. They were, however, separated by one very stark barrier: the one separating the country’s two distinct media systems, one controlled by the state, and one independent. Drawing on an original survey conducted in September 2020, just as the protest movement was reaching its peak, this article finds that respondents’ choice of news media was the strongest and most consistent predictor of their political opinions. Media, then, appear to have served not merely as aggregators of and conduits for social processes generated elsewhere, but as the producers of social and political force in their own right."
