1957 Alexandra bus boycott
The 1957 Alexandra bus boycott was a protest undertaken against the Public Utility Transport Corporation (PUTCO) by the people of Alexandra in Johannesburg, South Africa. It is generally recognised as being one of the few successful political campaigns of the Apartheid era, by writers and activists such as Anthony Sampson and Chief Albert Luthuli.
