Book excerpt: This book comprises the first full-length comparison of Scottish, Irish, English and Welsh migration within Europe in the early modern period. Divided into four sections - 'Immigrants and Civilian Life', 'Diplomats and Travellers', 'Protestants and Patrons' and 'Catholics at Home and Abroad' - it offers a new perspective on several themes. Contributors elucidate networks of traders, soldiers, as well as scholars and religious figures. Material regarding patterns of residence (sometimes of the nature of an enclave, sometimes not), places of worship, choice of marital partners, and cases of return migration, is presented, the results demonstrating clearly the fruitfulness of pursuing a comparative approach to seventeenth-century British and Irish history. Contributors are Waldemar Kowalski, Peter Davidson, Douglas Catterall, Steve Murdoch, Ciaran O’Scea, Éamon Ó Ciosáin, Igor Pérez Tostado, Kathrin Zickermann, Barry Robertson, Siobhan Talbott, Polona Vidmar, David J.B. Trim, Tom McInally, Thomas O’Connor and Caroline Bowden.
