The Manderscheid family was the most powerful family in the Eifel region of Germany for a considerable period of time in the 15th century. In 1457, Dietrich III von Manderscheid was made a Reichsgraf (Imperial count) by the Emperor (probably Frederick III). When Dietrich died on 20 February 1498, he had appointed his sons Johann, Konrad and Wilhelm as new rulers — the family property had been distributed in 1488.
