This book presents a detailed discussion of Indonesian future teachers' experience of religious diversity, tolerance and intolerance, their level of intellectual humility, and intentions to foster religious tolerance. Drawing from large-scale mixed methods research conducted in Indonesian universities involving over one thousand three hundred future teachers from diverse religious backgrounds, this book demonstrates that religion and religious beliefs can, and do, shape the way future teachers view their teaching practices and pedagogies.  The book sheds light into the under-researched yet prominent issue of integrating tolerance into teacher education preparation. It is set in the largest Muslim-majority country in the world which, in recent years, has seen a gradual degradation of secularity while religion becomes more dominant across all levels and sectors of society. This novel and timely book is of interest to researchers, scholars, and students in religious studies, education, social sciences, and Asian studies, as well as anyone interested in the interplay between religion and education in the 21st century.
