...admirable...the work is undoubtedly an impressive achievement. European History Quarterly
Bireley's study represents a major achievement. By providing a comprehensive, collective treatment to those supranational agents, the Jesuits, he has taken a hitherto neglected dimension for the study of the Thirty Years War and given it sustained, meaningful analysis and significant clarification for the period of Europe'sgestation and crisis. John M. Headley, University of North Carolina at Chapel Hill
In a tour de force of scholarship, Professor Bireley dispels the hoary myth of the Jesuits as a monolithic power behind the thrones of Europe's Catholic monarchs. His painstaking reconstruction of their activities in Madrid, Paris, Rome, Munich and Vienna demonstrates the considerable variations in both political intent and influence, not only between these great power centers, but also withing them. It also provides scholars with an invaluable trove of information about the great power diplomacy of the Thirty Years War. Charles Ingrao, Purdue University
Bireley brings a fresh perspective to the study of the Thirty Years' War. H-FRANCE
Jesuit confessors at the major courts of Catholic Europe during the Thirty Years War regularly corresponding with the Father General in Rome? This looks like a conspiracy. But instead the fascinating story that this magisterial book from the leading expert in the field reconstructs, after years of research in the archives of Europe, turns out to be one of conflicting personalities and loyalties-some promoting holy war, others intriguing for peace, and a Father General continuously arguing for more political restraint. Wolfgang Reinhard, Albert-Ludwigs- Universitat Freiburg
Birely's research is wide-ranging and meticulous, his narrative satisfying in its detail and his unique study will be of great value to research collections in history. Catholic Library World
