This work examines how the Welsh became absorbed into London's population yet retained aspects of Welsh culture from language to Eisteddfod, through societies. The study begins with the earliest contacts with the Welsh in Tudor London, through the Anglicization of the gentry to conformity and renaissance of Welsh literature in the 18th century. The book concludes with a series of essays noting the contributions of the London-Welsh to various aspects of Welsh life, and aspects of assimilation and acculturation, with a view from Wales of the nature of the London-Welsh migrant. The main concern of the study is with the lives of migrants as a whole, however the final chapter of the book deals more systematically with contributions to Welsh life through the achievements of individuals.
