This textbook specifically focuses on sociological theories of development for upper undergraduate students of sociology, international development studies, South Asian studies, and related courses. From social evolution to neoliberal modernity, the authors systematically apply globally recognized theories to the unique realities of South Asia, providing readers with a nuanced and in-depth understanding of the region's developmental challenges and opportunities. Covering theorists from Auguste Comte to Amartya Sen, this textbook not only critiques prevailing theories but also offers an indispensable case study of South Asia to bridge the gap between theoretical discourse and practical application. Based on the authors' own course, the content and structure of the book, including Learning Objectives, Multiple Choice Questions, and Review Questions with answers, has proved effective in teaching the sociology of development, specifically in the context of low- and middle-income countries.
