House of Luxembourg
During these 130 years, the House of Luxembourg was contending with the House of Habsburg for supremacy within the Holy Roman Empire and Central Europe. It all came to end in 1443, when the House of Luxembourg suffered a succession crisis, precipitated by the lack of a male heir to assume the throne. Since Sigismund and Elizabeth of Görlitz were both heirless, all possessions of the Luxembourg Dynasty were redistributed among the European aristocracy. The Duchy of Luxembourg become a possession of Philip the Good, Duke of Burgundy.
