Southern Africa the Imprisoned Society (SATIS) was a coalition that worked for the release of political prisoners in Southern Africa. Its founding conference, attended by 200 people on 8 December 1973, split into workshops like the one in the photograph addressed by former political prisoner Hugh Lewin. The conference set up a campaign that brought together the AAM, International Defence and Aid Fund (IDAF), National Union of Students, and the Ruskin and AUEW (TASS) Kitson Committees. For the next 20 years SATIS worked on behalf of Southern African political prisoners and for the release of all those detained without trial. In the 1980s it led campaigns to save the lives of political activists sentenced to death by the apartheid government.
