"Dietrich VI (also known as Dietrich of Meissen), was Count of Cleves from 1260 through 1275. He was born in 1226 as the son of Dietrich V, Count of Cleves and Hedwig of Meissen.
The County of Cleves (German: Grafschaft Kleve; Dutch: Graafschap Kleef) was a comital polity of the Holy Roman Empire in present Germany (part of North Rhine-Westphalia) and the Netherlands (parts of Limburg, North Brabant and Gelderland). 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)
