Restoration literature is the English literature written during the historical period commonly referred to as the English Restoration (1660–1689), which corresponds to the last years of the direct Stuart reign in England, Scotland, Wales, and Ireland. In general, the term is used to denote roughly homogeneous styles of literature that center on a celebration of or reaction to the restored court of Charles II. It is a literature that includes extremes, for it encompasses both Paradise Lost and the Earl of Rochester's Sodom, the high-spirited sexual comedy of The Country Wife and the moral wisdom of The Pilgrim's Progress. It saw Locke's Treatises of Government, the founding of the Royal Society, the experiments and holy meditations of Robert Boyle, the hysterical attacks on theaters from Jeremy Collier, and the pioneering of literary criticism from John Dryden and John Dennis. The period witnessed news become a commodity, the essay developed into a periodical art form, and the beginnings of textual criticism.
