Editing Duchy of Guelders (section)

==Geography==
The duchy was named after the town of [[Geldern]] (''Gelder'') in present-day [[Germany]]. Though the present province of [[Gelderland]] (English also ''Guelders'') in the [[Netherlands]] occupies most of the area, the former duchy also comprised parts of the present Dutch province of [[Limburg (Netherlands)|Limburg]] as well as those territories in the present-day German [[States of Germany|state]] of [[North Rhine-Westphalia]] that were acquired by [[Kingdom of Prussia|Prussia]] in 1713, which included the duchy's capital [[Geldern]].

Four parts of the duchy had their own centres, as rivers separated them:
* the quarter of [[Roermond]], also called Upper Quarter or [[Upper Guelders]] – upstream on both sides of the [[Meuse (river)|Maas]], comprising the town of [[Geldern]] as well as [[Erkelenz]], [[Goch]], [[Nieuwstadt]], [[Venlo]] and [[Straelen]];
spatially separated from the Lower Quarters (Gelderland):
* the quarter of the county [[County of Zutphen|Zutphen]], also called the [[Achterhoek]] – east of the [[IJssel]] and north of the [[Rhine]], including [[Doesburg]], [[Doetinchem]], [[Groenlo]] and [[Lochem]];
* the [[Veluwe Quarter]] with Arnhem as its capital – west of the IJssel and north of the Rhine, with [[Elburg]], [[Harderwijk]], [[Hattem]] and [[Wageningen]];
* [[Nijmegen Quarter]], including [[Betuwe]] – south of the Rhine and north of the Maas (in between the rivers), including [[Gendt]], [[Maasbommel]], [[Tiel]] and [[Zaltbommel]]
