Define and Rule focuses on the turn in late nineteenth-century colonial statecraft when Britain abandoned the attempt to eradicate difference between conqueror and conquered and introduced a new idea of governance, as the definition and management of difference. Mahmood Mamdani explores how lines were drawn between settler and native as distinct political identities, and between natives according to tribe. Out of that colonial experience issued a modern language of pluralism and difference.

A mid-nineteenth-century crisis of empire attracted the attention of British intellectuals and led to a reconception of the colonial mission, and to reforms in India, British Malaya, and the Dutch East Indies. The new politics, inspired by Sir Henry Maine, established that natives were bound by geography and custom, rather than history and law, and made this the basis of administrative practice.

Maine’s theories were later translated into “native administration” in the African colonies. Mamdani takes the case of Sudan to demonstrate how colonial law established tribal identity as the basis for determining access to land and political power, and follows this law’s legacy to contemporary Darfur. He considers the intellectual and political dimensions of African movements toward decolonization by focusing on two key figures: the Nigerian historian Yusuf Bala Usman, who argued for an alternative to colonial historiography, and Tanzania’s first president, Mwalimu Julius Nyerere, who realized that colonialism’s political logic was legal and administrative, not military, and could be dismantled through nonviolent reforms.

“Provocative, elegantly written.”
—Fara Dabhoiwala, New York Review of Books

“Demonstrates how a broad rethinking of political issues becomes possible when Western ideals and practices are examined from the vantage point of Asia and Africa.”
—Pankaj Mishra, New York Review of Books

In case after case around the globe—from Israel to Sudan—the colonial state and the nation-state have been constructed through the politicization of a religious or ethnic majority at the expense of an equally manufactured minority. The model emerged in America, where genocide and internment on reservations created a permanent native minority. In Europe, this template would be used both by the Nazis and the Allies.

Neither Settler nor Native offers a vision for arresting this process. Mahmood Mamdani points to inherent limitations in the legal solution attempted at Nuremberg. Political violence demands political solutions: not criminal justice but a rethinking of the political community to include victims and perpetrators, bystanders and beneficiaries. Making the radical argument that the nation-state was born of colonialism, he calls on us to delink the nation from the state so as to ensure equal political rights for all who live within its boundaries.

“A deeply learned account of the origins of our modern world…Mamdani rejects the current focus on human rights as the means to bring justice to the victims of this colonial and postcolonial bloodshed. Instead, he calls for a new kind of political imagination…Joining the ranks of Hannah Arendt’s Imperialism, Frantz Fanon’s The Wretched of the Earth, and Edward Said’s Orientalism, this book is destined to become a classic text of postcolonial studies and political theory.”
—Moustafa Bayoumi, author of How Does It Feel to Be a Problem?

“A masterwork of historical comparison and razor-sharp political analysis, with grave lessons about the pitfalls of forgetting, moralizing, or criminalizing this violence. Mamdani also offers a hopeful rejoinder in a revived politics of decolonization.”
—Karuna Mantena, Columbia University

“A powerfully original argument, one that supplements political analysis with a map for our political future.”
—Faisal Devji, University of Oxford
