Its rulers, called counts, had a special and privileged standing in the Empire. The County of Cleves was first mentioned in the 11th century. In 1417, the county became a duchy (German: Herzogtum Kleve; Dutch: Hertogdom Kleef) and its rulers were raised to the status of Dukes." - (en.wikipedia.org 23.05.2021)
