Chapter 18: Sections 1

2. Main Idea
Rivalries among European nations led to the outbreak of war in 1914.

3. Sparks of World War I
The Black Hand plotted to assassinate Archduke Franz Ferdinand
most of Europe plunged into war within five weeks.

4. ArchDuke Francis Ferdinand
On July 23, 1914, Austria-Hungary presented Serbia with a lengthy list of demands, with a 48 hour period in which to comply. These demands included abolishing all Pan-Serb propaganda, expelling from office any persons thought to have nationalist sympathies, taking legal action against certain officials designated by Austria-Hungary, and allowing agents of the Dual Monarchy to control all investigations and proceedings concerning the Sarajevo murders. Minutes before the July 25th deadline, Serbia issued a conciliatory reply to Berchtold's demands, stating that Serbia wished the dispute to be submitted to the International Tribunal at the Hague. This conciliation was rejected. On July 28, 1914, Austria-Hungary declared war on Serbia. World War I had begun.
Austrian reaction to the assassination was swift, as the Sarajevo crisis was seen as the Empire's last chance to assert its supremacy in the Balkans. Austrian foreign minister Count Leopold von Berchtold was determined to make use of the assassinations to crush once and for all the Serbian nationalist movement. Berchtold sent an envoy to Berlin, who was assured by Emperor William II on July 5th that Germany would fully support any action which the Dual Monarchy might take against Serbia. On July 6th, German chancellor Theobald von Bethmann-Hollweg issued the blank check of unconditional German support.
As Francis Ferdinand and his party proceeded through Sarajevo, the first of the Black Hand operatives tossed a bomb at the Archduke's automobile. The chauffeur saw the explosive and accelerated to avoid the impact. Sophie ducked, and Francis Ferdinand deflected the bomb with his arm, causing it to bounce off the back of the car and explode behind them, demolishing the next car and seriously injuring several aides. To avoid capture and interrogation, the unsuccessful assassin, nineteen-year-old Nedjelko Cabrinovic, swallowed a cyanide pill and jumped into the river. However, he was hauled out of the river and detained.
As the Archduke's entourage resumed its tour of Sarajevo, the Archduke's chauffeur took a wrong turn and drove within ten feet of another Black Hand agent, Gavrilo Princip. Princip stepped up to the car and fired two pistol shots. One bullet hit Sophie, killing her instantly. The other hit Francis Ferdinand, who died within minutes. Like Carbinovic, Princip attempted suicide, but was captured before succeeding.
ArchDuke Francis Ferdinand
On the morning of June 28, 1914, while traveling in a motorcade through Sarajevo, the capital city of Bosnia and Herzegovina, Archduke Francis Ferdinand and his wife Sophie were assassinated by a Serbian nationalist.
The Archduke was chosen as a target because Serbians feared that after his ascension to the throne, he would continue and even heighten the persecution of Serbs living within the Austro-Hungarian empire.
The Serbian terrorist organization, the Black Hand, had trained a small group of teenage operatives to infiltrate Bosnia and carry out the assassination of the Archduke.
