The recent assassination of Prime Minister Karl von Stürgkh shocked the Austrian elite. Now Franz Josef has filled that vacancy by appointing Ernest von Koerber as premier. Koerber had previously spent some time as Austrian prime minister in the early years of the century. More recently he was serving as finance minister for the whole empire.
Koerber is an old man, born in 1850 (just two years after the accession of Franz Josef). As the Austrian parliament has effectively been suppressed, Koerber holds his post at the pleasure of the emperor. This makes him a far less significant figure than Tisza, the Hungarian prime minister, who is responsible to the Hungarian parliament.
