Netherlands

English has a whole set of phrases that use Dutch as a slight.

The split door is a genuine feature of Dutch building. Other Dutch phrases in English come from 17th-century rivalry rather than description.

It joins Dutch courage and Dutch uncle in English's long grudge against the Dutch.

English built up a family of insulting "Dutch" compounds during the naval and trade rivalries of the 1600s, and later slang kept adding to it. American use muddies the question further, since "Dutch" there often stands instead for Deutsch, meaning German.

A thoroughly French sauce called Dutch, for reasons nobody has ever pinned down.

Hollandaise means in the Dutch manner, and the competing guesses are Dutch butter, Dutch eggs, or a wartime renaming of a Normandy sauce from Isigny when French butter ran short. None of them is documented, and the recipe appears in French kitchens under several names before this one stuck.

The brindle coat exists to stop anyone confusing it with the German shepherd.

The Hollandse herdershond was a working farm dog of the Dutch countryside, and its breed standard was written in 1898. Brindle was fixed as the required color to keep the breed distinct from the German and Belgian shepherds. Dutch sheep farming collapsed and nearly took the breed with it; it survives mostly as a police and military dog.
