Affinity Groups

Summary

A small (5–15 person), trusted group that organises and acts together — the basic unit of anarchist and movement-organising practice, especially for direct action — now extended by climate-movement adaptations including the explicit care role and the stress-inoculation rehearsal as prerequisites for safe action.

Body

An affinity group is a small, self-organising cluster of people who know each other well enough to make fast collective decisions in a high-pressure action. WRI’s Handbook for Nonviolent Campaigns treats affinity groups as the basic building block of action safety and decision-making, with the same structure used whether the action is a sit-in, a banner-drop, or a coordinated block of rapid-response phone calls [source: wri-handbook]. Seeds for Change publishes facilitation guides for affinity-group meetings and consensus, plus the discipline of the spokes-council — when multiple affinity groups need to coordinate, each sends a single mandated spokesperson who can speak for and report back to the group [source: seeds-for-change]. The same pattern (small trusted teams + spokes-council coordination) underpins the distributed-organising models that the Commons Library describe for large digital campaigns [source: commons-library].

The contemporary climate-movement adaptations add layers the original anarchist and civil-rights affinity groups did not have. XR-DE’s Bezugsgruppen-Handbuch makes the care role explicit — a member of the group whose job is to monitor the others’ emotional state and create space for a participant to withdraw consent on the morning of the action without losing face [source: xr-de-bezugsgruppen-handbuch]. The action-prep literature treats rehearsals that simulate the action’s cognitive and emotional load as a precondition for affinity-group cohesion under stress; the German Blockadefibel adds a structured morning-of-action checklist that operationalises the consent-withdrawal discipline. Beautiful Trouble’s jail-solidarity card lays out the pre-planned arrestee-support handoff at the level of the affinity group [source: beautiful-trouble].

FAQ

What is an affinity group?

An affinity group is a small, self-organising cluster of people who know each other well enough to make fast collective decisions in a high-pressure action. Typically five to fifteen people, it is the basic unit of anarchist and movement-organising practice, especially for direct action, now extended by climate-movement adaptations including the explicit care role and the stress-inoculation rehearsal as prerequisites for safe action.

How do affinity groups coordinate at mass actions?

When multiple affinity groups need to coordinate, each sends a single mandated spokesperson to a spokes-council who can speak for and report back to the group. The same pattern of small trusted teams plus spokes-council coordination underpins the distributed-organising models the Commons Library describes for large digital campaigns.

What does the care role add to climate-movement affinity groups?

XR-DE’s Bezugsgruppen-Handbuch makes the care role explicit — a member of the group whose job is to monitor the others’ emotional state and create space for a participant to withdraw consent on the morning of the action without losing face. The German Blockadefibel adds a structured morning-of-action checklist that operationalises the consent-withdrawal discipline. [source: xr-de-bezugsgruppen-handbuch]

What role does the jail-solidarity card play?

Beautiful Trouble’s jail-solidarity card lays out the pre-planned arrestee-support handoff at the level of the affinity group. WRI’s Handbook for Nonviolent Campaigns treats affinity groups as the basic building block of action safety and decision-making, used whether the action is a sit-in, a banner-drop, or a coordinated block of rapid-response phone calls.
