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 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.
Lynne Brown (born 26 September 1961) is the Minister of Public Enterprises and former Premier of the Western Cape province in South Africa.
 She was born in Cape Town and grew up in Mitchell's Plain.
 She was appointed Premier of the Western Cape following the resignation of Ebrahim Rasool in July 2008.
 Previously, she was Minister for Economic Development and Tourism.
 She is a member of the African National Congress and elected member of its National Executive Committee in 2007 and 2012.
 Like her predecessor Ebrahim Rasool she is also from a coloured background.
 She is the fourth coloured premier of the Western Cape, and the second from the African National Congress, and is believed the first openly gay person to be appointed to a cabinet post in any African government.
John Nyathi "Poks" Pokela (1922 or 1923 – 30 June 1985) was a South African political activist and Chairman of the Pan Africanist Congress (PAC).
 Born in Herschel in the Transkei region, he was educated at Healdtown Comprehensive School and the University of Fort Hare.
 Originally a member of the African National Congress Youth League, he left the African National Congress and helped found the PAC in the late 1950s.
Anton Lembede (21 January 1914 – 30 July 1947) was a South African activist and founding president of the African National Congress Youth League (ANCYL).
 He has been described as "the principal architect of South Africa's first full-fledged ideology of African nationalism."
 Lembede had a strong influence on Nelson Mandela, Walter Sisulu and Oliver Tambo and worked with them to reform the ANC, which the Youth League described as "a body of gentlemen with clean hands".
 He never saw the success of Black activism that enabled Black South Africans to be treated equally; he died in 1947, aged 33.
 Lembede was regarded as the progenitor of the "Programme of Action" that was adopted as a guiding document by the 1949 meeting of the African National Congress.
The Raid on Gaborone (called Operation Plecksy by the South African Defence Force) occurred on 14 June 1985 when South African Defence Force troops, under the order of General Constand Viljoen, crossed into Botswana and attacked the offices of Umkhonto we Sizwe (MK), the military wing of the African National Congress, in Gaborone.
 The raid, the fifth South African attack on a neighbouring country since 1981, killed 12 people including women and children; only 5 of the victims were members of the African National Congress.
The African National Congress Women's League is the women's wing of the African National Congress (ANC).
 It was founded in 1931 as the Bantu Women's League, with Charlotte Maxeke as its first president.
 It was integrated into the ANC during the period from 1943, when women were first admitted as members of the ANC, to 1948, when the ANCWL was officially founded.
 It participated with the Federation of South African Women in protests against the apartheid-era government, such as the 1952 Defiance Campaign and the Women's March of 9 August 1956.
 In 1956, Lilian Ngoyi became the first elected female member of the ANC National Executive Committee.
 In 1960 the organization was banned along with the ANC forcing its central leaders underground; it was unbanned in 1990 when the ANC was likewise unbanned.
Julius Sello Malema (born 3 March 1981) is the leader of the Economic Freedom Fighters, a South African political party, which he founded in July 2013.
 He previously served as President of the African National Congress Youth League from 2008 to 2012.
 Malema was a member of the ANC until his expulsion from the party in April 2012.
 He occupies a notably controversial position in South African public and political life, having risen to prominence with his support for African National Congress president, and later President of South Africa, Jacob Zuma.
 He has been described by both Zuma and the Premier of Limpopo Province as the "future leader" of South Africa.
 Less favourable portraits paint him as a "reckless populist" with the potential to destabilise South Africa and to spark racial conflict.
