This article analyzes the dynamics of turnout and the political impact of five cycles of protest, consisting of forty-two mass demonstrations that occurred on Mondays in Leipzig over the period 1989–91. These demonstrations are interpreted as an informational cascade that publicly revealed some of the previously hidden information about the malign nature of the East German communist regime. Once this information became publicly available, the viability of the regime was undermined. The Monday demonstrations subsequently died a slow death as their informational role declined.
Susanne Lohmann is Assistant Professor of Political Science at the University of California, Los Angeles. She has published a number of articles on the informational underpinnings of political action. She is currently working on a book analyzing the informational dynamics of political action and emigration in preunification East Germany and of public opinion polls and elections in postunification East Germany.
