We speak with the acclaimed academic and writer Mahmood Mamdani, who has just released a new book, Slow Poison: Idi Amin, Yoweri Museveni, and the Making of the Ugandan State. Mamdani, who has taught at Columbia for decades, was raised in Uganda and first came to the United States in the 1960s to study. He and his family were later expelled from Uganda during Idi Amin’s dictatorship. The book “is about the reversal of the anti-colonial movement” in Uganda, says Mamdani. “The anti-colonial movement fought to create a nation out of a fragmented country … and I speak of slow poison as a gradual, piecemeal, step-by-step cutting up of the country so that you no longer have a single citizenship.”
