Coups and Democracy


This study uses new data on coups d’état and elections to document a striking development: whereas the vast majority of successful coups before 1991 installed durable rules, the majority of coups after that have been followed by competitive elections. The article argues that after the Cold War, international pressure influenced the consequences of coups. In the post-Cold War era, countries that were most dependent on Western aid were the first to embrace competitive elections after their coups. This theory also helps explain the pronounced decline in the number of coups since 1991. While the coup d’état has been (and still is) the single most important factor leading to the downfall of democratic governments, these findings indicate that the new generation of coups has been far less harmful for democracy than their historical predecessors.
