This is not a definitive list and can be improved. Please contact us if we are missing a group (include a reference).

Criteria for listing was extremist Anarchist/Communist organizing (direct action, militia training, generation or distribution of extremist material, direct riot support). Groups like PSL/DSA were ignored as they are largely irrelevant for those purposes.

Some of these groups are inactive, the criteria was active within last 5-10 years

Locations are general and mean to show general city/state location and not to indicate any sort of group 'HQ', which only exist in rare cases such as The Base (now defunct) or other anarchist book stores that have acted as organizing spaces for violent extremists to plan attacks

We pulled this information from Social Media pages (Instagram, Twitter, Kolektiva, AntiCap.party, Telegram, and Bluesky), blogs (Blackblogs/Noblogs), Riseup Mailing lists, and shared reportbacks/statements that list groups

Logos are pulled directly from groups, with default Antifaschistische Aktion red/black flag provided for those without one. The exception to this was for groups operating as 'chapters' like YLF, JBGC, SRA, those icons defaulted to the general group icons if one wasn't found.

We started tracking international groups in October 2025 to better cover the transnational structure of left wing terror, as such they may not be as comprehensive as the American listing, please contact us if you can point to specific groups not listed here as language barriers for some countries introduce challenges.

Group size and frequency of activity is not documented here
