Counter Reformation, Catholic Reformation, the Baroque Age, the Tridentine Age, the Confessional Age: why does Catholicism in the early modern era go by so many names? And what political situations, what religious and cultural prejudices in the nineteenth and twentieth centuries gave rise to this confusion? Taking up these questions, John W. O’Malley works out a remarkable guide to the intellectual and historical developments behind the concepts of Catholic reform, the Counter Reformation, and, in his felicitous term, Early Modern Catholicism. The result is the single best overview of scholarship on Catholicism in early modern Europe, delivered in a pithy, lucid, and entertaining style. Although its subject is fundamental to virtually all other issues relating to sixteenth- and seventeenth-century Europe, there is no other book like this in any language.

More than a historiographical review, Trent and All That makes a compelling case for subsuming the present confusion of terminology under the concept of Early Modern Catholicism. The term indicates clearly what this book so eloquently demonstrates: that Early Modern Catholicism was an aspect of early modern history, which it strongly influenced and by which it was itself in large measure determined. As a reviewer commented, O’Malley’s discussion of terminology ‘opens up a different way of conceiving of the whole history of Catholicism between the Reformation and the French Revolution.”

The Council of Trent (1545–1563), the Catholic Church’s attempt to put its house in order in response to the Protestant Reformation, has long been praised and blamed for things it never did. Now, in this first full one-volume history in modern times, John W. O’Malley brings to life the volatile issues that pushed several Holy Roman emperors, kings and queens of France, and five popes—and all of Europe with them—repeatedly to the brink of disaster.

During the council’s eighteen years, war and threat of war among the key players, as well as the Ottoman Turks’ onslaught against Christendom, turned the council into a perilous enterprise. Its leaders declined to make a pronouncement on war against infidels, but Trent’s most glaring and ironic silence was on the authority of the papacy itself. The popes, who reigned as Italian monarchs while serving as pastors, did everything in their power to keep papal reform out of the council’s hands—and their power was considerable. O’Malley shows how the council pursued its contentious parallel agenda of reforming the Church while simultaneously asserting Catholic doctrine.

Like What Happened at Vatican II, O’Malley’s Trent: What Happened at the Council strips mythology from historical truth while providing a clear, concise, and fascinating account of a pivotal episode in Church history. In celebration of the 450th anniversary of the council’s closing, it sets the record straight about the much misunderstood failures and achievements of this critical moment in European history.
