The Habsburg-Lorraine dynasty formed the ideological basis for the Habsburg Monarchy, since the existence of the multi-ethnic state was primarily a product of the dynastic history of this ruling house.
In the latter days of the Habsburg Monarchy, Emperor Franz Joseph personified the imperial idea, although towards the end of his sixty-eight-year reign he was reduced more and more to an abstract symbol, a kind of father figure. His death in November 1916 left a vacuum at the head of the dynasty, which his successor Karl could no longer fill.
