On Saturday, 27 April, South Africa will celebrate Freedom Day, the on which South Africa held its first democratic elections. But the events that unfolded before that monumental day were grim.
Black-and-white pictures were projected onto the wall of a South African classroom and gospel music played evocatively in the background.
The pictures told a chilling tale: Angry protesters. Policemen beating crowds. Corpses lying scattered on the road. Coffins piled up.
The date of these events – 21 March 1960 – is etched in the annals of history.
