A novelist, poet and essayist, Achebe was perhaps best known for his first novel Things Fall Apart, which was published in 1958. The story of the Igbo warrior Okonkwo and the colonial era, it has sold more than 10m copies around the world and has been published in 50 languages. Achebe depicts an Igbo village as the white men arrive at the end of the 19th century, taking its title from the WB Yeats poem, which continues: "Things fall apart; the centre cannot hold."
"The white man is very clever. He came quietly and peaceably with his religion. We were amused at his foolishness and allowed him to stay. Now he has won our brothers and our clan can no longer act like one," says Okonkwo's friend, Obierika, in the novel.
The poet Jackie Kay hailed Achebe as "the grandfather of African fiction" who "lit up a path for many others", adding that she had reread Things Fall Apart "countless times".
"It is a book that keeps changing with the times, as he did," she said.
