The Northern Ireland conflict, known as “The Troubles,” mixed religion and politics and caused many civilian casualties. In 1976, after three children were killed in a car incident linked to violence, Williams and Corrigan founded the grassroots group “The Peace People.” They organized cross-community rallies, urging society to “break the chain of violence,” and drew tens of thousands within months. Their non-violent campaign highlighted that peace building need not rely solely on security forces or armed groups. Their work fostered dialogue among opponents and laid social groundwork that later supported formal peace agreements.

The Peace People made civic power visible through petitions, door-to-door outreach, and support for victims, reducing social legitimacy for violence. Williams and Corrigan used media skillfully, mobilizing international opinion to pressure the British government and the Northern Ireland administration. Their strategy drew on Gandhian and Kingian non-violence while adding a female-led ethics of care. They also ran inter-faith schools and children’s exchange camps, supporting long-term reconciliation. These initiatives are widely cited in conflict-transformation literature as a successful case of bottom-up peacebuilding.

The Peace People employed a “moral jiu-jitsu” non-violent strategy that reframed the conflict and slowed resource mobilization by violent actors. Early mass mobilization interacted reciprocally with shifting political opportunity structures after the 1975 cease-fire collapse, establishing the “voice of mothers” as a dominant frame in the framing contest. They created meso-level peace constituencies, expanding inter-communal social capital and presaging elements later embedded in the multilayered Good Friday Agreement. Impact studies show a short-term decline in fatality datasets and rising public support, although critiques highlight organizational institutionalization failures and civil-society fatigue. The case remains widely cited as a composite example of non-state norm entrepreneurship and gendered peacebuilding.
