The last two decades have seen a total shift in the study of early modern Catholicism. These changes are underlined on a wider scale by the launch of the Catholicisms, c. 1450–c. 1800 series of which this collection is the first volume. Moreover, the archival riches of Church bodies, especially religious orders, have stimulated multiple research projects based on Catholic sources written in a non-confessional manner. These upheavals in the field are particularly evident in scholarly approaches to British and Irish Catholicism, as a growing number of researchers have recognised the importance of the subject both to national and global history. This burgeoning interest is indicated by the renaming of the journal Recusant History as British Catholic History, and the launch of the biennial Early Modern British and Irish Catholicism conference jointly organised by Durham University and the University of Notre Dame. A sign of the subject's coming of age is that, at the time of writing, work is ongoing on the five volumes that will result in The Oxford History of British and Irish Catholicism.

Rather than embark on an in-depth study of all the publications that have contributed to this surge, the editors wish to instead use this Introduction to make a historiographical intervention in how the field has rapidly developed. This collection seeks to reorientate the recent direction of scholarship on early modern Catholicism, and especially in relation to Britain and Ireland, by focusing on the activities of the conventual and monastic religious orders. Current research trajectories have resulted in a historiographical imbalance, which has led to an over-emphasis being placed on the role of the Society of Jesus in the development of British and Irish Catholicism following the Protestant Reformation. In reality, the stable communities of conventual religious in mainland Europe acted as important centres of religious and secular activity. This volume explores the ways in which these communities, both male and female, engaged with the seismic religious and philosophical developments of the early modern period, such as the Catholic Reformation and the Enlightenment in mainland Europe, as well as important political developments at ‘home’, exploring the connections between centres and peripheries. It seeks to recapture the roles played by conventuals and religious, and recover their place in a historiography that is in danger of overlooking them.
