In this first book devoted to Milton's engagement with Ireland, Lee Morrissey takes an archipelagic approach to his subject. The study focuses on the period before the Cromwellian Conquest, explaining Milton's emergence as a public figure because of Ireland and tracing the paradoxical resonances of Milton's republicanism in Ireland to this day. Informed by developments in Irish history but foregrounding a lucid discussion of Milton's governmental prose works, Morrissey explores the tension between Milton's long-established image as a proto-Enlightenment, democratic figure, and the historical reality of his association with a Protestant invading force. Milton's Ireland incisively negotiates this complex subject, addressing clear absences in Milton scholarship, in the history of Ireland, and in the fraught relationship between Ireland and England.
