Restoration poetry marked a shift from Puritan austerity to a more liberal society. John Dryden emerged as the leading figure, developing the heroic couplet and shaping literary criticism. His works often served as political commentary and propaganda for the Stuart monarchy. Dryden's influence extended beyond his lifetime, impacting 18th-century poets and the Neoclassical aesthetic. His mastery of satire, wit, and formal techniques established him as a key figure in English literature, despite changing critical reception over time.
