Abstract What role can international engagement play for the relationship between post-conflict democratization and conflict recurrence? Empirical evidence indicates that democratization risks triggering violence. Consequently, some scholars criticize the liberal peacebuilding approach, which centers on the promotion of democracy and competitive elections with the aim of fostering peace after civil wars. This article (1) illustrates the risks and potential of post-conflict democratization and (2) traces the effect of international support in this context. It builds on the existing literature yet goes beyond the concentration on peacekeeping forces and places particular attention on democracy promotion. The analysis draws on rich empirical data from Liberia, which is an ideal case to explore this relationship. Twice, democratic elections followed in the wake of a devastating civil war in Liberia. The first post-war elections in 1997 are often cited as an example of how externally induced democratization triggers renewed violence. The democratization process following the end of the second civil war in 2003, in contrast, is regarded as having strengthened peace. The analysis shows that international (democracy) support constitutes a key explanatory factor in the Liberian case by reducing and even substituting for the weakness and lack of credibility of local democratic institutions and procedures.
