[1] In the Dutch province of Limburg, the King's Commissioner is usually called Gouverneur (governor), as in Belgium.

Similarly, the Provinciehuis (Province Hall) in Maastricht is called Gouvernement (Governor's Residence).

As per the 1839 Treaty of London, The Netherlands recognised Belgium's independence, but special provisions were made for Limburg (and Luxembourg).

The province was divided into two, roughly taking river Meuse as the border, with most of the eastern half, although now an integral part of the Dutch territory, becoming a member of the German Confederacy as the "Duchy of Limburg" to appease Prussia, which had lost access to the Meuse after the Congress of Vienna.

The folklore custom to call the local King's Commissioner "Governor" dates from these times; nowadays it is used to underline the Limburgers' (self-)perceived otherness from "regular" Dutchmen.
