"The Limburg-Luxemburg dynasty, one of several families from different periods known as the Luxembourg dynasty (French: Maison de Luxembourg; German: Haus Luxemburg) was a royal family of the Holy Roman Empire in the Late Middle Ages, whose members between 1308 and 1437 ruled as King of the Romans and Holy Roman Emperors as well as Kings of Bohemia (Čeští králové, König von Böhmen) and Hungary. Their rule was twice interrupted by the rival House of Wittelsbach." - (en.wikipedia.org 29.09.2019)
