How does civil society affect support for the political system during times of political crises? Some argue that civil society strengthens support for political systems by increasing trust and participation. Yet recent scholarship demonstrates that civil society can also facilitate mobilization and dissent, which may undermine support for the political system, especially in times of crisis. We test these competing claims using individual-level data from a country in the midst of a major political crisis: Bolivia in 2004. We find that membership in civil society organizations leads to higher levels of diffuse support for the political system even during a crisis—and even among those who have recently participated in protest. Civil society, however, is not associated with higher support for government during the crisis. Despite extremely high levels of mobilization, extreme dissatisfaction with government, and evidence that membership in associations actively facilitates political protest, civil society continues to be positively associated with support for the political system.
