Amilcar Cabral: an African liberation legend

We remember Amilcar Cabral, who led the armed struggle against Portuguese colonial rule in West Africa in the 1970s and speak to Dr Nayanka Perdigao about his legacy. Plus the shocking fallout of the Indian rail strike in 1974 which was - at the time - the biggest industrial action on record and from a century ago, the Tulsa race massacre, when thousands of African Americans were left homeless and hundreds were killed. We'll also find out how Lotfia Elnadi became the first Arab woman pilot in 1933 and the story behind the first big charity fundraising rock concert in the Soviet Union when communism broke with its antipathy toward western pop music.Photo: Rebel soldiers on patrol in Guinea Bissau during the Portuguese Colonial War in West Africa, 1972.
