It is now over 100 years since Cunningham wrote Alien Immigrants to England, which focused heavily upon the impact of immigration in later 16th and early 17th century England: it has yet to be supplanted by a comprehensive, up-to-date survey. Although much research has been completed on the subject, particularly during the past three decades, relatively little of this has appeared in mainstream history journals, while more general surveys have tended to concentrate upon the second wave of migration that followed the Revocation of the Edict of Nantes in 1685.
