The Anarchist Black Cross (ABC), formerly the Anarchist Red Cross, is an anarchist support organization. The group is notable for its efforts at providing prisoners with political literature, but it also organizes material and legal support for class struggle prisoners worldwide. It commonly contrasts itself with Amnesty International, which is concerned mainly with prisoners of conscience and refuses to defend those accused of encouraging violence. The ABC openly supports those who have committed illegal activity in furtherance of revolutionary aims that anarchists accept as legitimate.

Stuart Christie was a Scottish anarchist writer and publisher. When aged 18, Christie was arrested while carrying explosives to assassinate the Spanish caudillo, General Francisco Franco. He was later alleged to be a member of the Angry Brigade, but was acquitted of related charges. He went on to found the Cienfuegos Press publishing house, as well as radical publications The Free-Winged Eagle and The Hastings Trawler, and in 2006 the online Anarchist Film Channel, which hosts films and documentaries with anarchist and libertarian socialist themes. His memoir Granny Made Me an Anarchist was published in 2004.
