Herzogtum Luxemburg

The Duchy of Luxembourg (French: Luxembourg; German: Luxemburg; Luxembourgish: Lëtzebuerg) was a state of the Holy Roman Empire, the ancestral homeland of the noble House of Luxembourg. The House of Luxembourg became one of the most important political forces in the 14th century, competing against the Houses of Habsburg and Wittelsbach for supremacy in the Holy Roman Empire. They would be the heirs to the Přemyslid dynasty in the Kingdom of Bohemia, succeeding to the Kingdom of Hungary and contributing four Holy Roman Emperors until their own line of male heirs came to an end and the House of Habsburg received the territories that the two Houses had originally agreed upon in the Treaty of Brünn in 1364.
