This book is a reconstruction of the way Hugo Grotius (1583–1645) was read and used by English political and religious writers in the seventeenth and early eighteenth centuries. The book is broad in approach, covering the reception of all of Grotius’ key works and a wide range of topics. It has much to say also about the search for peace in an age of religious conflict and about the cultural roots of the Enlightenment. Most of all, this book aims to deepen our understanding of the connections that made English political thought part of the history of European thought. To this end, it brings together a succinct account of Grotius’ own thinking on key topics; maps these accounts onto English debates, to show why his ideas were seen to be relevant at key moments; shows awareness of the possibilities for misappropriation inherent in reception; and adds something new to our understanding of why seventeenth-century Englishmen argued in the ways that they did. The subject the book covers is potentially of wide interest to historians of political thought, religion, and culture; to British and European historians; and to historians with an interest in international history, specifically the cultural and intellectual links between England and the Dutch Republic.
