The start of World War 1
World War 1 is one of the most talked-about events in history. It was the first time the whole world had been engaged in war, resulting in high casualty rates. It all started with some assassination.
Anyone who has read about the WW1 knows that the assassination of Archduke Ferdinand by Gavrila Princip is what triggered the war. This was the last picture of Archduke when he was still alive. He was killed an hour later after this photo was taken.
