I am living in what is today as well as in 1836 the province of Noord-Brabant. Overall I think that the way the CLIO project has depicted the Netherlands is not too bad, but I have found some oddities on the map. After seeing the map from Samuel Augustus Mitchell I know where the mistakes come from.
I agree with Niptium that Samuel Augustus Mitchell's map of the Netherlands is one of the worst around and I also think that the 17th century maps from Willem Blaeu are better.
One thing I found odd is the fact that CLIO's Zeeland comprises half of West-Brabant. In reality Zeeland only contained the southwestern islands (excluding Goeree and Overflakkee, which belong to South Holland) and Zeeuwsch-Vlaanderen (the part south of the Westerschelde, north of Gent).
What I also find odd is the fact that CLIO's Eindhoven also contains the Land of Maas en Waal and the Rijk van Nijmegen, regions that back in 1836 as well as now belong to Gelderland.
Niptium's statement that 19th century Zeeland largely consisted of disconnected islands is true, but the distances between the islands are small enough to be bridged by armies with an engineer corps. It does not take a full fledged fleet to take the province. Gamewise Zeeland should not be treated like an island province. IMHO the province should be treated like an ordinary coastal province, to be freely entered from the north, east and south. Only coastal landings from the sea should be difficult.
I want to close my post with some statements about maps.
Better maps of 19th century Netherlands can be found below:
United Kingdom of the Netherlands (Netherlands, Belgium and Luxembourg) in 1830
The red line indicates the border between the Netherlands and Belgium from 1830 onwards.
United Kingdom of the Netherlands in 1816
After 1830, Limburg and Luxembourg would be split, with Limburg west of the Meuse river becoming Belgian and the rest remaining Dutch. Luxembourg was split into the present-day Grand Duchy of Luxembourg (an independent state, in personal union with the Netherlands until 1890) and the province of Luxembourg (nowadays a province of Belgium with Arlon as its capital).
The
Bosatlas van Nederland, Wolters-Noordhoff, 2007 also contains some good maps about the historical evolution of Dutch provinces over the centuries, including a map of Dutch provinces from 1850.
Map of Dutch provinces as of 2009 Accurate depiction of 19th century Netherlands (if you remove Flevoland), at least more accurate than the map from Samuel Augustus Mitchell. I know it is a bit silly to use a contemporary map for describing 19th century borders, but apart from the creation of Flevoland, Dutch provincial borders have hardly changed since Belgium became independent.
