Hate & Extremism

We monitor hate and antigovernment extremist groups throughout the United States and expose their activities to the public, the media and policy makers.

The Intelligence Project at the SPLC works to expose, prevent, counter and remedy hate and extremism in the U.S. today. The SPLC is the premier U.S. organization monitoring the activities of domestic hate groups and antigovernment hard right extremists – including the Ku Klux Klan, white nationalists, the neo-Nazi movement, antigovernment militias, anti-LGBTQ groups, antisemitic movement, anti-Muslim groups and others.

We track more than 1,500 hard right extremist groups operating across the country. We publish investigative reports and offer expert analysis to lawmakers, the media and public. To push white supremacy out of the mainstream and remedy harms in communities, we spot warning signs and intervene proactively by supporting grassroots partners and building community resilience to extremism.

Our work fighting hate and extremism began in the early 1980s, amid a resurgence of Klan violence that began several years after the end of the civil rights movement. Each year since 1990, we have released an annual report and census of U.S. hate and antigovernment groups. In the mid-1990s, we also began documenting the number of radical, antigovernment militias movement organizations.

Over the years, we’ve crippled or destroyed some of the country’s most notorious hate groups – including the United Klans of America, the Aryan Nations and the White Aryan Resistance – by suing them for murders and other violent acts committed by their members or by exposing their activities. We continue to hold hate groups and extremist individuals accountable using a varied set of tools and enhanced technological capacity for data analysis, including a DataLab to apply measurement techniques for studying networks of toxicity, hate speech, racism and extremism in online social spaces.
