This paper seeks to address the constitutional paths that followed the Arab awakening in both Tunisia and Egypt. The Tunisian constitutional process, despite some tensions, was largely peaceful and consensual. On the other hand, the process in Egypt of establishing a new constitutional arrangement had been tumultuous with repercussions that are likely to linger on for a protracted period of time. Therefore, despite apparent resemblance in socio-political actors in both countries, (political Islam, army intervention, strong institutional tradition, young population, etc.) the paper aims at identifying the factors have impacted both the constitutional drafting process and the popular perception of the produced constitutions in each of Tunisia and Egypt.
