But, Emperor Frederick II preferred that Luxembourg was held by a lord Germanic rather than French and attributed the county to Henry of Limburg-Arlon (see below), son of Conrad's aunt Ermesinde and Count Godfrey I of Namur.The election was necessary after the Habsburg king Albert I of Germany had been murdered, and Henry, backed and orchestrated by his brother Archbishop-Elector Baldwin of Trier, prevailed against Charles, Count of Valois.The prince-electors, perturbed by the rise of the Luxembourgs, disregarded the claims raised by Henry's heir King John, and the rule over the Empire was assumed by the Wittelsbach duke Louis of Bavaria.The family's decline began under Charles' son King Wenceslaus, deposed by the prince-electors in 1400 who chose the Wittelsbach Elector Palatine Rupert.The Habsburgs finally prevailed as Luxembourg heirs, ruling the Empire until the extinction of their senior branch upon the death of Maria Theresa in 1780.
