Count Heinrich Karl Clam-Martinic (1 January 1863, Vienna – 7 March 1932, Klam) was an Austrian statesman. 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 December 13, 1916, soon after the death of Emperor Franz Joseph on November 21, 1916.[1] As Prime Minister, he replaced Ernest von Koerber and was succeeded by Ernst Seidler von Feuchtenegg (1917-1918), Baron Max Hussarek von Heinlein (1918), and Heinrich Lammasch (1918).
His short-lived cabinet included famous Austrian figures such as Karl Urban and Joseph Baernreither.
