This book explores norm diffusion in non-Western contexts. It analyzes how norms transfer and what mechanisms or sources of leverage facilitate their diffusion. The individual chapters follow an interdisciplinary framework that analyzes social norms beyond the theoretical tradition of international relations, and focus on particular cases of diffusion-both successful and unsuccessful-across the non-Western world. In this way, the book challenges existing perspectives and advances critical norm research that diversifies the agency of norm entrepreneurs beyond processes of norm localization. It makes a twofold contribution-by deepening our theoretical understanding of norms and their dynamics and by broadening the geographical scope of norms research.
