Among other analyses addressing the collapse of Mubarak regime in Egypt, the present study attempts to explain the Egyptian 2011 revolution on the basis of the state’s structure in the country. Indeed, the focal point of the study is to reveal “why” Mubarak’s regime was so vulnerable towards the social turbulency. It seems that a three-pillar approach can lead to a proper answer, whose pillars consist of: 1. The patrimonial structure of the state; 2. The nature of the political economy in authoritarian states (which leads to vulnerability towards the changes in socio-political behavior); and 3. The economic and political dependency of the authoritarian regimes on the super-powers (which makes them more vulnerable). On the basis of the historical data on the Mubarak regime (1981- 2011), the present study attempts to credit this three-pillar approach towards the regime change in Egypt.
