He was one of the last Prime Ministers in the Austrian half of the Austro-Hungarian empire, he was called during World War I to head a new cabinet by Emperor Charles on 13 December 1916, soon after the death of Emperor Franz Joseph on 21 November 1916.John W.

He was succeeded by Ernst Seidler von Feuchtenegg (1917-1918), Baron Max Hussarek von Heinlein (1918), and Heinrich Lammasch (1918).
