On June 28 1914 Archduke Franz Ferdinand, heir to the Austria-Hungarian throne was assassinated by Serbia nationalist Gavrilo Princip while on a formal trip to Sarajevo. Unbeknown at the time, this assassination would be the breaking point between the already tense and nationalistic European countries during this era.
Many countries inside Europe had strong nationilistic feelings, they believed that their country was greater than the next. Countries wanted to prove who was the best, they all wanted to go to war in someway or another. The assisnation of franz Ferdinand gave a reason to Autria-Hungary to go to war with a smaller country(Serbia). Serbia was nationalistic as well, they were upset because of a prior war in which land was lost. The assisnation was not the only cause of the war.
