After heated years 1905-1907 thousands of anarchists and socialists were sent to labour camps and exile, first groups of Anarchist Black Cross (until 1919 called Anarchist Red Cross) were founded 1906 to support them. Organisation became international the next year already, when a group was set up in London. Although contact with anarchist political prisoners of the Soviet Union was lost in 1930's, international organisation has continued its activity in various forms ever since.
Russian anarchist movement newborn in 1980's was immediately targeted with repressions, and during the following 15 years several succesfull and unsuccesfull campaigns against repression were organised. But during first years of the 21st century these initiatives disappeared completely from Moscow, and in summer of 2003 it was decided to refound Moscow group of ABC, since still no-one is protecting anarchists against repressions except anarchists themselves.
