With the possible exception of Sir Geoffrey Elton and Lawrence Stone, no present historian of Tudor and Stuart England has been more prolific or controversial than Christopher Hill, the former master of Balliol College, Oxford. The twenty-nine articles, lectures, and book reviews included in the first two volumes of his Collected Essays deal with many of the themes developed in his more recent books, beginning with The World Turned Upside Down: Radical Ideas During the English Revolution (London, 1972). Although two of the pieces appeared as early as the 1950s, Hill has revised the essays for this collection, so that the total corpus reflects his mature judgment.
