Context paragraphs:
1990 in South Africa: 1990 in South Africa saw the official start of the process of ending Apartheid.  President of South Africa, F.W. de Klerk announced plans to end apartheid.  President De Klerk unbanned organisations that were banned by the government including the African National Congress, the South African Communist Party and the Pan Africanist Congress.  The African National Congress' armed wing, Umkhonto we Sizwe, suspends its armed activity within South Africa.  Political prisoners including Nelson Mandela were released.  Nelson Mandela met ANC leader Oliver Tambo for the first time in 28 years at a meeting in Sweden.  Mandela also traveled to England to thank the people for their support in the campaign to free him.  South Africa withdrew its troops from Namibia, which was granted independence.  1990 also saw marches in support and against the formation of a new post-Apartheid South Africa.

Siphiwe Mvuyane: Siphiwe Mvuyane was a South African police officer who died on 9 May 1993.  During the period of "low intensity warfare" in South Africa which largely pitted the African National Congress (ANC) and Inkatha Freedom Party (IFP), Siphiwe Mvuyane was on the side of the IFP.  During the period of the "low intensity warfare", the IFP was the sole ruling party of the Bantustan KwaZulu government, and worked in collaboration with the apartheid government, whereas the ANC was operating underground; as a result the IFP had an upper hand over the ANC when it came to the warfare.  But post apartheid, the African National Congress (ANC) became the governing party in South Africa whereas the Inkatha Freedom Party (IFP) became one of the opposition parties in the South African parliament, as a result the ANC gained the upper hand over the IFP in the remaining years of the warfare as the ANC was in control of the state apparatus by virtue of being the governing party.  The IFP leadership denied its involvement in sanctioning and orchestrating political violence in the furtherance of its political objectives during the period of the "low intensity warfare" in South Africa.
