Taking a random selection of documents from the Norfolk Record Office’s very extensive ‘Designated’ holdings of archives, this paper attempts to demonstrate the wealth of primary source material available in Norfolk for the study of the county’s relations with the Low Countries, over a period, which spans almost a millennium. It considers the ‘Strangers’ who came to Norfolk from the Low Countries during the sixteenth and seventeenth centuries, but it also seeks to set this group within a wider chronological canvas; the arrival of the ‘Strangers’ into the county was an important occurrence, but it was only one episode in a long history of links stretching across the North Sea, a fact which is sometimes overlooked. Close contacts between Norfolk and its nearest continental neighbours already existed in the Middle Ages and these have continued strongly up to the present time. Such links have undoubtedly had a significant impact on the county and its people, and have helped to shape Norfolk’s identity and character today. Many of the activities that stemmed from the relationships between Norfolk and the Low Countries generated records, which have survived in large numbers, and these help to tell a long and fascinating story.
