(D) ** Assassination of Archduke Franz Ferdinand
EXPLANATIONS BELOW
Concept note-1: -Archduke Franz Ferdinand of Austria and his wife Sophie are shot to death by a Bosnian Serb nationalist during an official visit to the Bosnian capital of Sarajevo on June 28, 1914. The killings sparked a chain of events that led to the outbreak of World War I by early August.
Concept note-2: -The political objective of the assassination was to free Bosnia and Herzegovina of Austria-Hungarian rule and establish a common South Slav ("Yugoslav") state. The assassination precipitated the July Crisis which led to Austria-Hungary declaring war on Serbia and the start of World War I.
Concept note-3: -Just hours after narrowly escaping an assassin’s bomb, Archduke Franz Ferdinand, the heir to Austro-Hungarian throne and his wife, the Duchess of Hohenberg, are killed by Gavrilo Princip. A month later, Austria-Hungary declares war on Serbia and Europe rapidly descends into chaos.
Concept note-4: -The assassin – Gavrilo Princip – was a member of a Bosnian Serb nationalist group seeking to unite territories containing ethnic Serbs under Serbia’s control. Convinced that the Serbian government had assisted Princip’s group, Austria-Hungary issued a series of harsh demands, most of which the Serbs accepted.
