Saving Nelson Mandela: The Rivonia Trial and the Fate of South Africa by 
Kenneth S. Broun has just been published by Oxford University Press in the series Pivotal Moments in World History.   With a taut 169 pages of text, and reasonably priced, this well-written account of an important moment in the struggle against apartheid in South Africa strikes me as valuable resource for course use, not only in legal history in Africa, but for courses on the role of law in social change.  Here's the book description:
 When South Africa's apartheid government charged Nelson Mandela with  planning its overthrow in 1963, most observers feared that he would be  sentenced to death. But the support he and his fellow activists in the  African National Congress received during his trial not only saved his  life, but also enabled him to save his country.
When South Africa's apartheid government charged Nelson Mandela with  planning its overthrow in 1963, most observers feared that he would be  sentenced to death. But the support he and his fellow activists in the  African National Congress received during his trial not only saved his  life, but also enabled him to save his country. 
In Saving Nelson Mandela,  South African law expert Kenneth S. Broun recreates the trial--called  the "Rivonia" Trial after the Johannesburg suburb where police seized  Mandela. Based upon interviews with many of the case's primary figures  and portions of the trial transcript, Broun situates readers inside the  courtroom at the imposing Palace of Justice in Pretoria. Here, the trial  unfolds through a dramatic narrative that captures the courage of the  accused and their defense team, as well as the personal prejudices that  colored the entire trial. The Rivonia trial had no jury and only a  superficial aura of due process, combined with heavy security that  symbolized the apartheid government's system of repression. Broun shows  how outstanding advocacy, combined with widespread public support, in  fact backfired on apartheid leaders, who sealed their own fate. 
Despite his 27-year incarceration, Mandela's ultimate release  helped move his country from the racial tyranny of apartheid toward  democracy. As documented in this inspirational book, the Rivonia trial  was a critical milestone that helped chart the end of Apartheid and the  future of a new South Africa.
