Anthills and paralysis (1987–1999)

In 1987 Achebe released his fifth novel, Anthills of the Savannah, about a military coup in the fictional West African nation of Kangan. A finalist for the Booker Prize, the novel was hailed in the Financial Times: "in a powerful fusion of myth, legend and modern styles, Achebe has written a book which is wise, exciting and essential, a powerful antidote to the cynical commentators from 'overseas' who see nothing ever new out of Africa." An opinion piece in the magazine West Africa said the book deserved to win the Booker Prize, and that Achebe was "a writer who has long deserved the recognition that has already been accorded him by his sales figures." The prize went instead to Penelope Lively 's novel Moon Tiger.

On 22 March 1990, Achebe was riding in a car to Lagos when an axle collapsed and the car flipped. His son Ikechukwu and the driver suffered minor injuries, but the weight of the vehicle fell on Achebe and his spine was severely damaged. He was flown to the Paddocks Hospital in Buckinghamshire, England, and treated for his injuries. In July doctors announced that although he was recuperating well, he was paralyzed from the waist down and would require the use of a wheelchair for the rest of his life. Soon afterwards, Achebe became the Charles P. Stevenson Professor of Languages and Literature at Bard College in Annandale-on-Hudson, New York; he held the position for more than fifteen years. Throughout the 1990s, Achebe spent little time in Nigeria but remained actively involved in the country's politics, denouncing the usurpation of power by General Sani Abacha.
