These are lists of rulers in the Low Countries. The Low Countries, historically also called the Netherlands, possessed clearly delineated boundaries only after 1500. Still in many respects they demonstrated common traits and underwent similar development that differentiated them from surrounding countries. The social, economic and political similarities evident throughout most of the region stem from the High Middle Ages, when the Scheldt, Maas and Rhine delta area became an important center of trade. Next to Northern Italy, the Low Countries became the most urbanised and prosperous region in Europe. Its political system exhibited, from relatively early on, a degree of representative government that differed from the more feudal arrangements then existent in much of Europe. Internationally, the region served both as a mediator for and a buffer to the surrounding great powers, France, England, and Germany.
