The discipline of International Relations (IR) has been subjected to various questions, challenges, and reformulations in the recent past. Certain paradigmatic challenges emanate from various theoretical orientations that question the foundations of mainstream IR. A different set of criticisms flow from questioning the European-American bias of the discipline. There have been recent strides in terms of changing IR’s focus from the major powers of the West to the so-called peripheral countries. However, such a change and supposed inclusiveness does not apply to the theorization of IR. The book under review contributes toward such a shift; it seeks to bring out what the margins or the periphery has to offer for theorizing IR. The subtitle Homegrown Theorizing refers to the task of bringing out the “original theorizing in the periphery about the periphery” (p. 4). The book is an outcome of a workshop convened in 2016 at the Center for Foreign Policy and Peace Research, which included participants who sought to go beyond conventional ways of theorizing. Building upon homegrown perspectives, the selection of essays in the book present new insights toward theorizing IR.
