In this important and timely collection of essays, historians reflect on the middle class: what it is, why its struggles figure so prominently in discussions of the current economic crisis, and how it has shaped, and been shaped by, modernity. They focus on specific middle-class formations around the world—in Africa, Asia, Europe, the Middle East, and the Americas—since the mid-nineteenth century. The contributors scrutinize these formations in relation to the practices of modernity, to professionalization, to revolutionary politics, and to the making of a public sphere. Taken together, their essays demonstrate that the historical formation of the middle class has been constituted trans-nationally through changing, unequal relationships and shifting racial and gender hierarchies, colonial practices, and religious divisions. That history raises questions about taking the robustness of the middle class as the measure of a society’s stability and democratic promise. Those questions are among the many stimulated by The Making of the Middle Class, which invites critical conversation about capitalism, imperialism, post-colonialism, modernity, and our neo-liberal present.
