This volume seeks to explore whether the current violence, its origins and dynamics can best be understood as a manifestation of civil war. In so doing, it considers how the use of violence by all parties has been conditioned and/or constrained by the domestic factors pertaining to their societies, how external actors have dealt with the violence internally, and how this has impacted on their relations with Israel and the Palestinians, and what does the conduct and scope of the al-Aqsa Intifada suggest about the broader issue of state boundaries and state legitimacy in the contemporary Middle East? This volume was previously published as a special issue of the journal Civil Wars.
