The Nelson Mandela 70th Birthday Tribute took place on 11 June 1988 at Wembley Stadium, London, and was broadcast across 67 countries to a worldwide audience of 600 million people. Mandela was still an imprisoned anti-apartheid revolutionary at the time of the concert, but the event is considered a pivotal step leading to the eventual release of Mandela, in February 1990, following 27 years of incarceration. Unlike the Live Aid concert a few years earlier, the 1988 concert was not primarily a fundraiser (even though it made £5million) but an event intended to raise the awareness worldwide of the injustice occurring under the apartheid regime in South Africa at the time.
