Domestic Extremism

Over the last several years, the threat posed by white supremacists, accelerationists, the militia movement, and other extremists has surged. Today, the landscape of domestic extremism in America has metastasized. From attacks on synagogues and black churches to the siege against America's democracy on January 6th, these threats continue to expand and evolve. Our researchers have examined domestic extremist groups and movements from a number of angles. Check out featured news and publications, major projects, and a full archive of related content below.

Projects

 

Capitol Hill Siege

In keeping with our tradition of providing primary source documents to the research community and the public at large, The Program on Extremism launched a project to create a central database of court records related to the events of January 6, 2021. The project database is updated daily as additional individuals are charged with criminal activities and new records are introduced into the criminal justice system. You can view today's numbers, check out our interactive visualizations, browse the cases, read our related reports, and download our database by visiting the Capitol Hill Siege page. 


 

Domestic Terrorism Tracker

The Program on Extremism regularly releases our Domestic Terrorism Tracker as part of our GW Extremism Tracker series. From the Boogaloo movement to Neo-fascist Skullmask groups like Atomwaffen Division, Feuerkrieg Division, and The Base, our Domestic Terorrism Tracker provides up-to-date information on legal proceedings and the demographics of these extremist movements. 


 

Racially and Ethnically- Motivated Attacks

In March 2021, the Office for the Director of National Intelligence released an assessment that the “most lethal domestic violent extremist threat[s]” to the United States were racially and ethnically motivated violent extremists (RMVE). Responding to RMVE-inspired terrorists will require a close, data-driven assessment of the nature and scope of the threat. To this end, The Program on Extremism analyzed 40 cases of individuals charged in United States federal courts between 2014 and 2019, who are alleged to have planned or conducted violent attacks in the United States in furtherance of RMVE causes or ideologies. By evaluating the demographic, ideological, and organizational backgrounds of the perpetrators, as well as their attack-planning methods and processes, this we evaluate the successes and failures of federal law enforcement in investigating and prosecuting RMVE attack planners.


 

Addressing White Supremacism

The United States has struggled to adapt to a changing domestic terrorism landscape. To meet today's demands, The Program on Extremism and the Anti-Defamation League analyzed the arrests of dozens of domestic extremists, as well as current efforts by law enforcement to disrupt and counter the growing influence of white supmreacy. We focus on the current state of enforcement actions against two domestic white supremacist networks: The Base and Atomwaffen Division. We also outline a number of administrative actions, legislative and policy changes, and other possible federal and state legal and prosecutorial powers that could allow for a more comprehensive and effective approach to countering these threats.


 

Countering Antisemitism

Antisemitism is pervasive throughout several categories of American extremist movements, both violent and non-violent. American extremists incorporate antisemitic tropes and narratives in every level of their worldviews, using them to help construct “us/them” dichotomies and wide-sweeping conspiracies that are essential to their movements. We assess that antisemitism is foundational to multiple violent extremist movements in the United States, and counter-extremism practitioners and scholars may consider incorporating antisemitism as a diagnostic factor for extremist radicalization.


 

Anarchist/Left-Wing Violent Extremism in America

Anarchist/left wing violent extremism, often referred to in United States government parlance with the catch-all term “anarchist violent extremism” (AVE), has a long-standing history in the U.S. Over the last several years, violence committed by AVEs was largely locally organized, eventdriven, and/or opportunistic. However, we found that ongoing changes in the political, social, and economic climate in the U.S., as well as changes in the makeup, strength, and doctrines of other American domestic extremist groups, have the potential to escalate the frequency and lethality of violence committed by AVEs in the immediate future.
