Who was elected leader of XXX?
Austria
During the 1914 July Crisis that followed the assassination of Archduke Franz Ferdinand of Austria, Germany guided Austria in issuing the ultimatum to Serbia that led to the declaration of World War I. After the collapse of the Habsburg (Austro-Hungarian) Empire in 1918 at the end of World War I, Austria adopted and used the name the Republic of German-Austria (Deutschösterreich, later Österreich) in an attempt for union with Germany, but was forbidden due to the Treaty of Saint-Germain-en-Laye (1919).
