Book excerpt: A must-read book for understanding this vibrant and influential modern Jewish movement Hasidism originated in southeastern Poland, in mystical circles centered on the figure of Israel Ba’al Shem Tov, but it was only after his death in 1760 that a movement began to spread. Today, Hasidism is witnessing a remarkable renaissance around the world. This book provides the first comprehensive history of the pietistic movement that shaped modern Judaism. Written by an international team of scholars, its unique blend of intellectual, religious, and social history demonstrates that, far from being a throwback to the Middle Ages, Hasidism is a product of modernity that forged its identity as a radical alternative to the secular world.
