The Commission of Inquiry into Certain alleged Murders was appointed by the then State FW de Klerk on 2 February 1990, in response to outcries by South African and international human rights groups over allegations by three former police officers in October and November 1989 that they had been members of an officially authorized and funded police death squad. In early 1990, another death squad, the Civil Cooperation Bureau (CCB), sponsored by the South African Defense Forces, was revealed. The allegations presented the de Klerk government with one of its first major domestic crises

However, the Harms Commission suffered from extremely restricted terms of reference that were very strictly applied by Harms and which prevented the investigations to go beyond the borders of the country. Therefore, the Harms Commission was seriously flawed in both design and practice. At the outset, Justice Harms announced that he would limit the inquiry to acts committed within the borders of South Africa, even though many anti-apartheid activists had been assassinated on foreign soil. Government witnesses, some of whom showed up to testify in wigs and other disguises, were not required to produce pertinent documents. The CCB was disbanded in August, but no prosecutions resulted. The Harms Commission report, which was released in September 1990, failed to name any special units of the army or police, let alone any individual officers, as participants in the death squads. The report was denounced by opposition groups as a whitewash.

The Medu Art Ensemble was formed by South Africa exiles in Gaborone, Botswana, in 1978. The organisation produced a wealth of creative work across all major art-forms; the roup further played a key role in shaping aesthetic and cultural theory and praxis within Africanist and liberation struggles. On June 14 1985, the South African Defence Force attacked the homes of Medu members and other activists in Gaborone, killing 12 people; Medu as an organisation ceased to exist.

The Anti-Apartheids Beweging Nederland (AABN) (Dutch Anti-Apartheid Movement) was formed in 1971. Among those involved in the founding was a South African, the Afrikaner Berend Schuitema. The organization focused on the liberation struggle in Rhodesia/Zimbabwe and South Africa. The AABN supported the African National Congress and various solidarity campaigns for divestment from companies doing business in South Africa and the release of political prisoners. AABN also campaigned in support of the arms, oil and cultural boycotts of South Africa. In 1997 it was one of three organizations which had been active as supporters of the anti-apartheid that merged to form the Netherlands Institute on Southern Africa (NiZA).

The Kairos Foundation (Stichting Kairos) was founded in 1970 as a support group for the Christian Institute in South Africa, whose general secretary was anti-apartheid activist Dr CF Beyers Naude. Kairos, a Greek word, means 'time is running out'.
