Bantu Stephen Biko was a South African anti-apartheid activist strongly opposed to the apartheid system of racial segregation and white-minority rule in South Africa.
The government came to see Biko as a subversive threat and placed him under a banning order in 1973, severely restricting his activities.
Following his arrest in August 1977, Biko was severely beaten by state security officers, resulting in his death. Over 20,000 people attended his funeral.
And Peter Gabriel wrote a song about it.
