After Sharpeville, ANC leader Oliver Tambo was exiled and Albert Luthuli agreed to continued non-violence - by contrast Mandela set up the MK (Umkhonto we Sizwe)
MK aimed to liberate black South Africans and those treated as unequal via more violent protest; they opted for violence against property rather than openly against the white community
Mandela, still “banned” had to work underground (”Black Pimpernel”), MK HQ was in Rivonia, Johannesburg and the bombings started in 1961
In 1962, Mandela left South Africa and arrested upon return, no proof of connection to MK, he was charged with minor offences
The 1962 Sabotage Act: effectively added the death penalty, to anyone guilty of damaging property for political reasons; targeted at MK
1963-4: Mandela and 7 others were prosecuted under the Sabotage Act (charged with high treason), the Rivonia trial; evidence from a July police raid on underground communist base, trial in Rivonia because the base was in Rivonia
Mandela was found guilty but spoke for 4 hours (reported internationally, banned in South Africa), he led out his ideas of a fair democracy (equal political/domestic rights and treatment); against “separate but equal”
12th June 1964 - all accused sentenced to lie imprisonment and held at pretoria central prison before being flown to Robben Island
