Beginning in the 14th century, Berndorf – then still known as “Berendorf” – belonged to the Electorate of Trier, and more locally to the "Amt" of Hillesheim. According to a “patronage under oath” undertaken by two "Amtmänner" ("Amt" officials) in 1379, the Margraves of Jülich also exercised their rights in “Berendorf”.
