Book excerpt: This book centres on the key concept of diversity and relates it to the identity formation of Muslims. Muslim identity differs specifically within certain theological, social, political and regional circumstances and discourses. Considering the diversity of societies and the numerous factors contributing to the shaping of Muslim identity, this book brings together examples from different parts of the world, including Western societies, and each chapter focuses on separate determinants of individual, communal, political, institutional, civic and national Muslim identities, offering a blueprint for identity studies. A particular strength of the book is its detailed investigation of the complexity of identity formation and the heterogeneity of the Muslim experience. In addition to including a variety of themes and cases from different parts of the world, diverse methodologies, including quantitative and qualitative research methods, further enrich the book. The contributors’ academic backgrounds and organic relationships with their communities enable them to develop their arguments with insight. Furthermore, by giving voice to academics from different nationalities, this book reflects neither a predominantly Western nor a distinctly Eastern approach, but instead gives a balanced view from critical academia globally.
