This book is concerned with one – albeit central – component of this story that awaits to be told, that of Scholem’s study of the Sabbatian movement. By presenting for the first time the narrative arc of what is arguably Scholem’s greatest scholarly achievement as informed by his own archive, Gershom Scholem and the Research of Sabbatianism offers a complete picture of the development of the scholarship of the critical chapter in the history of Jewish mysticism.
