Objective. Recent upheavals in the Middle East raise a number of questions regarding the consequences of mass uprisings. We examine the impact that earlier peaceful revolutions had on interpersonal and institutional trust in the postcommunist world. Methods. Data were collected from eight countries using two waves from the World Values Survey, three of which had experienced a colored revolt. The article uses mixed effects logit analysis and quasi-experimental techniques. Results. Levels of social trust are much less in countries where a colored revolution occurred than in countries that had not experienced such an uprising. However, confidence in political institutions increased in contrast to countries that had not experienced an uprising. Conclusion. The level of interpersonal trust is not necessarily connected to the level of institutional trust. The decline in interpersonal trust in post-colored-revolution societies does not bode well for the development of democracy after mass upheaval. TX 76203-5017 John.Ishiyama@unt.edu .

Further, although it could be argued that what occurred was not "revolutionary" in that no "progress" toward democracy was made afterward, in this article we conceptualize "revolutionary" as simply the collapse of the previous political administration and its replacement with the opposition as the result of mass protests over fraudulent election results.2 To be sure, we do not wish to make universal claims that stretch far beyond the countries included in this study, which are all in one region of the world, all of which were postcommunist, and all of which were semi-authoritarian regimes. Thus we do not claim that the findings apply to all popular uprisings (such as SOCIAL
