House of Luxembourg
The House of Luxembourg (Luxembourgish: D'Lëtzebuerger Haus; French: Maison de Luxembourg; German: Haus Luxemburg) or Luxembourg dynasty was a royal family of the Holy Roman Empire in the Late Middle Ages, whose members between 1308 and 1437 ruled as kings of Germany and Holy Roman emperors as well as kings of Bohemia, Hungary and Croatia. Their rule was twice interrupted by the rival House of Wittelsbach. The family takes its name from its ancestral county of Luxembourg which they continued to hold.
