Abstract

This dissertation uses data from the United States Extremist Crime Database (ECDB) to assess the nature of extremist violence between left-wing, far-right and al-Qaeda and associated movements (AQAM) inspired ideological fatal violence. It extends the empirical literature on extremist violence in three significant ways by: (1) expanding an existing database to provide a comparative component that is both timely and policy-relevant and conveys a more complete picture of the nature of domestic extremism in the U.S.; (2) systematically comparing extremist violence across the left-wing, far-right and AQAM ideologies to better assess the nuances of extremist violence; and (3) applying empirical analysis to better understand these issues.
