He called them “Pigs”, “Thieves”, and “Murderers”, just to name a few. This is significant because the place where he was going to, Bosnia-Herzegovina, was about 40% Serbian.
  • Assassination of Archduke Ferdinand (Cont.)

    When the Serbian’s heard that Archduke Ferdinand was visiting the territory, they made a plan to assassinate him, making him pay for what he said about their people.

The group was called the Black Hand and they were relatively close to the Serbian army.
  • Assassination of Archduke Ferdinand (Cont.)

    One of the Serbians threw a bomb at their car, but it bounced off of it and hit the car behind them, injuring the passengers and bystanders. Instead of leaving the area, Franz wanted to continue on his planned route to the City Hall. When that finished, he went to visit a hospital that the injured were staying in, coincidentally, Princip was right there. He then saw the Archduke, and took the opportunity to get revenge, pulling out a pistol, killing the Archduke and his wife (Greenspan, 2020).

The U-boat’s first use in WWI was on September 5, 1914. The attack was on the British off the coast of Scotland.
