When war broke out in South East Asia in 1941, one hill tribe - the Christian, English-speaking Karen - distinguished itself in the fight against Japan. Karen helped halt the Japanese, taught British Army regulars to fight in the jungle, and worked with Force 136 - the British sabotage unit immortalised in the fiction film 'The Bridge on the River Kwai'. Fifty years later they are fighting for their independence. Using newly unearthed archive material and documents, Timewatch tells why the Karen feel abandoned by the British and how they remain in a brutal civil war with the Burmese.

Transatlantic slavery was responsible for the largest long-distance forced migration in history. Europeans did not venture into the interior of Africa until after abolition, so how did approximately 12 million Africans fall into their clutches? Timewatch delves into history and finds that, contrary to popular belief, most of the business was conducted by black slave merchants trading on the coast with Europeans. And slavery was a fact of life long before the transatlantic trade began. For centuries, Africa supplied eunuchs and wives to the Arab world, sacrificial victims to tyrants, and domestic labour.
