The new series Disruptions of Orthodoxy offers a platform for books on religious groups outside or on the margins of the established communities and churches in early modern western culture. Such groups, often labelled dissenters, non-conformists or radicals by contemporaries, challenged established religious truths and practices, claiming spaces in churches and society. These outsiders, sometimes with a Jewish background, sometimes with an Islamic background, and sometimes with a Christian background, disrupted orthodoxies.  In doing so, they provided a stimulus to intellectual and social change as well as religious renewal.

Contributions to this series center on the ways in which these dissenters gave rise to new religious cultures, how religious 'substreams' interacted with the mainstream, and on how these substreams eventually became mainstream. The series seeks to invite interdisciplinary approaches to the field that comprise a range of perspectives and methodologies, including religious studies, intellectual history, book history, gender and women's studies, as well as cultural and literary history.
