The Rivonia Trial was a trial that took place in apartheid-era South Africa between 9 October 1963 and 12 June 1964, after a group of anti-apartheid activists were arrested on Liliesleaf Farm in Rivonia. The farm had been the secret location for meetings of uMkhonto we Sizwe (MK), the newly-formed armed wing of the African National Congress. The trial took place in Pretoria at the Palace of Justice and the Old Synagogue and led to the imprisonment of Nelson Mandela, Walter Sisulu, Govan Mbeki, Ahmed Kathrada, Denis Goldberg, Raymond Mhlaba, Elias Motsoaledi, Andrew Mlangeni. Many were convicted of sabotage and sentenced to life.

Ahmed Mohamed Kathrada OMSG, sometimes known by the nickname "Kathy", was a South African politician and anti-apartheid activist.
