On May 2nd, 1915 German Submarine's sunk a British ocean liner the Lusitania. This made many Americans angry. This was a reason for America joining World War 1. World War 1 also started because of the assassination of the heir to the Austria- Hungarian throne. On June 28th, 1914 Archduke, Francis Ferdinand and his wife were assassinated while going to Serbia which Austria Hungary had just taken over. He was assasinated in Sarajevo, Bosnia.The killer was Gavrilo Princip. Germany's attack on Belgium didn't help. This directly provoked Britain to come to war. These are main sparks that started World War 1.
