This article analyses coalition survival in eleven post-Communist, Central and Eastern European democracies. Survival analysis demonstrates that Communist Successor Parties (CSPs) are central to understanding government dissolution processes in post-communism. Coalitions spanning the ‘regime divide’ between CSPs and parties not affiliated with the ancien regime last longer than governments that do not. Regime divide governments also are more likely to fall during periods of positive economic performance, while other governments fall during periods of negative economic performance. The reason lies in parties’ incentives to prolong their regime divide coalition with the CSP, especially in the face of adverse conditions.
