Correspondence and papers of the Secretary of State concerning the southern part of the Netherlands, known as the Spanish Netherlands (until 1713) or Austrian Netherlands (1713 onwards). The territory was also known colloquially as Flanders although Flanders was only one of the component provinces.
The records are mainly in-letters, mostly to the Secretary of State or his assistants from the English (later British) Envoy Extraordinary, Resident, Minister Plenipotentiary or Agent at Brussels, and the Consul, or Vice-Consul, at Ostend. Many draft replies are included in the series, though they are less frequently found in the earlier volumes. Some petitions, royal warrants and royal letters are also in the series. Most of the later volumes contain some printed papers. Affairs at Dunkirk are sometimes the subject of correspondence, and plans of Dunkirk and the 'new' canal and sluices are included.
Many of the earlier papers are dated at Antwerp, Bruges, and (occasionally) Dunkirk.
