This article uses a comparison with Ukraine to investigate why protests against Lukashenka in 2020 failed to oust the Belarusian dictator. First, in contrast to his counterparts in Ukraine, Lukashenka successfully built new authoritarian economic and coercive institutions in the 1990s that raised the costs of opposition activity and reduced challengers’ access to business support. Second, Belarus has lacked a strong national identity that was critical to opposition success in Ukraine. In Ukraine, relatively powerful anti-Russian nationalism repeatedly motivated a core group of anti-incumbent activists and facilitated the opposition’s control over local power structures that supported protest activities at critical moments. In Belarus, weak national identity and consequent dearth of committed activists in national government institutions in the 1990s hampered efforts to challenge Lukashenka’s consolidation of authoritarian power. In addition, weaker national identity undermined the capacity of opposition forces to control local power structures that might have aided opposition protest.
