100 Women

In this special edition of Witness, and as part of the BBC's 100 Women season, Tanya Beckett introduces us to five extraordinary women and their stories that changed the course of history. We hear from the woman who led a protest against the contraceptive ban in Ireland, one of the South African schoolgirls who rioted in response to the Apartheid government's brutal regime and the female chess prodigy who defeated the world champion.
