Prince Ernst of Hohenberg ("Ernst Alfons Franz Ignaz Joseph Maria Anton von Hohenberg"; 27 May 1904 – 5 March 1954) was the second son of Archduke Franz Ferdinand of Austria and his morganatic wife Sophie, Duchess of Hohenberg, who were assassinated at Sarajevo in 1914.
Franz Ferdinand, Duke of Hohenberg (born 13 September 1927 at Artstetten Castle, Austria – died 16 August 1977 at Ried in der Riedmark, Austria), was the eldest son of Maximilian, Duke of Hohenberg and Countess Maria of Waldburg zu Wolfegg und Waldsee.

 As a result of that morganatic marriage, the Hohenbergs were excluded from the line of succession to the Austro-Hungarian throne.

Yugoslavism (Југославизам, Slovene: "Jugoslavizem" ) or Yugoslavdom (Југословенство, Slovene: "Jugoslovanstvo" ) refers to the nationalism or patriotism associated with South Slavs and Yugoslavia.
 Yugoslavism has historically advocated the union of all South Slav populated territories now composing Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, Serbia (and the disputed region of Kosovo, which now has a Slavic minority), Slovenia, and Macedonia.
 It became a potent political force during World War I with the assassination of Austrian Archduke Franz Ferdinand by the Yugoslavist militant Gavrilo Princip and the subsequent invasion of Serbia by Austria-Hungary.
 During the war the Yugoslav Committee composed of South Slav emigres from Austria-Hungary (including twelve Croats, three Serbs, and one Slovene), supported Serbia and vouched for the creation of a Yugoslav state.
 However the assassination of Franz Ferdinand triggered resentment amongst those Austro-Hungarian Croats and Slovenes who had favoured being within Austria-Hungary.
