The Campaign to Stop Control Unit Prisons was a coalition of individuals and groups inside of prison walls whose goal was to shut down all control units. The coalition was founded at a gathering hosted by the American Friends Service Committee in Philadelphia, PA in December 1994. Towards this end, campaign members were engaged in data collection, education, fostering public awareness and action to put an end to the human rights abuses occurring daily in control units.

In addition to mailing containing action items, news and updates around advocacy to end control units, the coalition also held regional hearings in opposition to control units and created an emergency response network to respond to emergencies related to control units and those held inside.
