The colonial presence in early modern Ireland is usually viewed as being thoroughly English, and in places Scottish, with the Welsh hardly featuring at all. This book, based on extensive original research, demonstrates that therewas in fact a significant Welsh involvement in Ireland between 1558 and 1641. It explores how the Welsh established themselves as soldiers, government officials and planters in Ireland. It also discusses how the Welsh, although participating in the 'English' colonisation of Ireland, nevertheless remained a distinct community, settling together and maintaining strong kinship and social and economic networks to fellow countrymen, including in Wales. It provides a detailed picture of the Welsh settler communities and their networks, and discusses the nature of Welsh settler identity. Overall, the book demonstrates how an understanding of the role of the Welsh in the shaping of early modern Ireland can offer valuable new perspectives on the histories of both countries and on the making of early modern Britain.
