Kerkrade is a town and a municipality in the southeastern Netherlands. It is the western half of a divided city which includes the German town of Herzogenrath. The original name in German of the undivided municipality under the Holy Roman Empire was Herzogenrath.
The two towns, including outlying suburban settlements, have a population approaching 100,000.
The history of Kerkrade is closely linked with that of the adjacent town of Herzogenrath, just across the German border. Herzogenrath began as a settlement, called Rode, near the river Worm (or Wurm in German) in the 11th century. In 1104 Augustinian monks founded an abbey, called Kloosterrade, to the west of this settlement.
It was called 's-Hertogenrode or 's-Hertogenrade (Dutch: the Duke's Rode) after the duchy of Brabant took control over the region; in French it was called Rolduc (Rode-le-duc). As is the case for many parts of the Southern Netherlands, the place changed hands several times in the last few centuries. It was under Spanish control from 1661, Austrian between 1713 and 1785 and French between 1795 and 1813. In 1815, when the kingdom of the Netherlands was formed (see Vienna Congress), the border was drawn through Herzogenrath, the western part being Kerkrade.
