This thesis aims at offering a deeper understanding of the phenomenon of settler violence in the West Bank. The purpose is to understand why part of the settler population was radicalized around 2006, and why violence has increased every year since. Three theories explaining civil violence and radicalism are combined in order to produce a thorough analysis of the causes of radicalization and continued increase and diffusion of violence. The study argues that the increase is due to a change in tactics on behalf of some settlers, and concludes that a tightening of the official attitude towards the settlement enterprise in 2005, which included targeting the unauthorized outposts, concluded a long process of delegitimation of the State in the eyes of the settlers. The change of government to a far more settlement friendly one in 2009 was not sufficient to appease the radical settlers, as anti-statism has grown to become a main element of their radicalized religious ideology. The existence of a large settlement supportive network in the political and bureaucratic systems has prevented the government from holding a clear stance towards the illegal actions of these radicals, and has led to very inconsistent state policies, and this has facilitated the observed increase in settler violence.
