This book assimilates new scholarship and deploys a wealth of original archival research to present a fresh picture of Wales under the Tudor and Stuart monarchs. It adopts novel perspectives on Welsh identity and allegiance to examine epochal events, such as the union of England and Wales under Henry VIII; the Reformation and the break with Rome; and the British Civil Wars and Glorious Revolution. It argues that Welsh experiences during this period can best be captured through widespread attachments to a shared history and language and to ideas of Britishness and monarchy. The volume looks beyond high politics to examine the rich tapestry of early modern Welsh life, considering concepts of gender and women's experiences; the role of language and cultural change; and expressions of Welsh identity beyond the principality's borders.
