The Crisis of the Seventeenth Century collects nine essays by Trevor-Roper on the themes of religion, the Reformation, and social change. As Trevor-Roper explains in his preface, “the crisis in government, society, and ideas which occurred, both in Europe and in England, between the Reformation and the middle of the seventeenth century” constituted the crucible for what “went down in the general social and intellectual revolution of the mid-seventeenth century.” The Civil War, the Restoration, and the Glorious Revolution in England laid the institutional and intellectual foundations of the modern understanding of liberty, of which we are heirs and beneficiaries.
