World War I battered the Western imperial systems and destroyed one, that of Germany, but it did not sound the death knell of an empire. The "scramble" for overseas territory ha reached a virtual conclusion shortly before the war; afterwards, the main business of empire was to ensure a pax colonia: the often contradictory goals of a stable government and economic development. It is with the years between world wars—the brief age of administrative empire — that Raymond Betts is chiefly concerned in this book. An unsettled time, when individuals coped with empire of uncertain dimensions, the interwar years nonetheless left a material legacy—railroads, motor roads, public buildings — and an ideological one—the voices of protest that led to independence after World War II.

Preeminently a cultural history of the era rather than a political narrative, Uncertain Dimensions centers upon the regions we now call the Third World—Subsaharan Africa and Southeast Asia—and the major colonial powers, Great Britain and France. Betts has structured this book as a group of closely linked interpretive essays, each devoted to a specific aspect of the late colonial experience: World War I and the postwar mandates, colonial administration, the European economic imperative and "technology transfer," urbanization, anti-imperial protest, and decolonization. Throughout, he draws upon the work of novelists, poets, and theoreticians—Aime Cesaire, Claude McKay, Leopold Sedar Senghor, Frantz Fanon, and many others—and recognizes the deep irony at the heart of modern imperialism: that contact between Western and Third worlds was mostly confined to two minorities, the alien European and the socially uprooted African or Asian.
