Cage is a London-based advocacy organisation which aims to empower communities impacted by the War on Terror. Cage highlights and campaigns against state policies, developed as part of the War on Terror. The organisation was formed to raise awareness of the plight of detainees held at Guantánamo Bay and elsewhere and has worked closely with former detainees held by the United States and campaigns on behalf of current detainees held without trial. Cage was formerly known as Cageprisoners, and is ordinarily styled as "CAGE".
