'... Royalists at War is a significant work of scholarship ...' Journal of British Studies 'This is an important and impressive book. It makes a significant contribution to our understanding of the civil wars of the mid-seventeenth century in Scotland and Ireland, and, in doing so, throws much new light on subjects - royalism, allegiance and identity - of central importance to our understanding of English history at the time.' Jason McElligott, The Keeper, Marsh's Library, Dublin, Ireland '... written in a clear, witty style. ... It will prove valuable, both as a model and a source, for future studies of 1640s Britain and Ireland.' Renaissance Quarterly 'This volume ... will be of use to anyone wishing for a well written overview of royalism within Scotland and Ireland during the Wars of the Three Kingdoms.' Sixteenth Century Journal 'As a study of noble, royalist, identity in Ireland and Scotland, this book will stand as an important resource for researchers and their students. By connecting with issues of definition discussed by historians of English royalism, Robertson provides a timely update to the seminal work David Stevenson while adding to the findings of Robert Armstrong and Keith Brown more recently. Moreover, this work is part of a wider dynamic that elevates studies of Ireland and, particularly, Scotland to a point where historians of other regions cannot help but take note ... Robertson's book is an important milestone in our appreciation of the differences of British and Irish experience.' Reviews in History
