The Arab Spring has become a prominent example of the spread of cross-national regime contention. It is widely
accepted that successful regime contention (in Tunisia and Egypt) triggered protests in other countries. Both scholars
and other observers have suggested that protesters learned from successful regime contention. Thus far, available
evidence has been either anecdotal or qualitative. This article provides a quantitative analysis of the diffusion of regime
contention in 20 countries in the Middle East and North Africa (MENA) region between December 2010 and April 2011.
Results show that protests that led to a regime change were much more likely to be imitated elsewhere, but especially
in the first couple of weeks and without taking the specificity of the context into account. Our analysis thus suggests that
regime contention diffused through bounded learning during the Arab Spring.
