In 1967, Nigerian writer Wole Soyinka tried to stop the country’s Biafra war, in which Nigeria’s Igbo people responded to violence by seceding from the rest of the country. They proclaimed a new Republic of Biafra.

When the fighting began, Soyinka was building a reputation as a poet and playwright abroad. However, in a last-ditch attempt to avert civil war, he set off on a secret mission behind the front line to meet the Biafran leader, Emeka Odumegwu Ojukwu. When he left Biafra, he was imprisoned by the federal government without trial for more than two years.

Soyinka drew on his prison experience in his writing over the following years, for which he was awarded the Nobel Prize in Literature in 1986 - the first African to win the award. He looks back on those events with Ben Henderson.
