Nelson Mandela is Arrested. The South African anti-apartheid activist and adherent of nonviolence was arrested by the government at Rivonia, a suburb of Johannesburg. After a year-long trial, Mandela was imprisoned at the infamous Robben Island prison where we spent the next 18 years. He was released from prison in 1990 after spending 28 years as a political prisoner. In the early 1990s, after intense international and domestic pressure, in part from the efforts of Mandela, the South African government started taking steps to end apartheid – a government policy of racial segregation and discrimination. As a result, Mandela was elected the country’s first black president in 1994.
