Robert Mangaliso Sobukwe was a prominent South African political dissident and teacher, who founded the Pan Africanist Congress in opposition to the South African apartheid system.
During his lifetime, Sobukwe was considered to be so dangerous by the National Party government that its parliament enacted the "Sobukwe clause", a statute which on its face seemed to grant broadly applicable powers, but was specifically intended to authorise the arbitrary extension of Sobukwe's imprisonment.
