In which John Green teaches you about Chinua Achebe's 1958 novel, Things Fall Apart. You'll learn about Igboland, a region in modern-day Nigeria, prior to the arrival of the British Empire. Achebe tells the story of Okonkwo, an Igbo villager who has worked his way up from life as a sharecropped and become a respected leader in his community. Okonkwo has a tragic fall and is exiled. And then the trouble starts. British missionaries arrive and change everything. Things Fall Apart has a lot to say about colonization and even something to say about decolonization.Consider supporting local bookstores by purchasing your books through our Bookshop affiliate link https://bookshop.org/shop/complexly​ or at your local bookseller.Crash Course is on Patreon!
