Democratically elected as Bolivia’s first indigenous president in 2005, Evo Morales eroded democracy and began a transition to competitive authoritarianism in the 2010s. By November 2020, however, both Morales and his successor, the right-wing president Jeanine Áñez, had fallen after failing to consolidate authoritarian rule. Why do some aspiring authoritarians succeed while many fail? A comparison of Bolivia to Brazil and Venezuela illuminates the challenges of both eroding democracy and institutionalizing new competitive authoritarian regimes. Aspiring autocrats must mobilize and control civil society in both stages of autocratization—a challenge that led to the fall of both Morales and Áñez.
