Factors that caused the first world war included imperialism, nationalism and secret diplomacy. It also had a lot of tension and rivalry between European nations.
Arming for War: It was a time when European nations spent a lot of money on their navies and military forces. This gave them a big advantage over other countries.
The assassination of the Austrian Archduke Franz Ferdinand was one of the main causes for the world war. He was assassinated by the Black Hand organization.
