The crime of the ages who did it

It was the assassination of Archduke Francis Ferdinand and his wife by Gavrilo Princip who is part of a group called the "Black Hand" that occurred on June 28, 194. The assassination was provoked when Austria demanded that the Serbs withdraw from Albania after defeating the Turks. This assassination triggered a chain of events that led to the outbreak of World War One. Alliances were formed and new types of weapons were invented that led to the deaths of soldiers on both sides and civilians.
