Causes of WWI

World War 1 had three different causes, Nationalism, Militarism, and the assassination of Franz Ferdinand. Nationalism is an extreme loyalty to one`s nation and concern for it`s welfare. It was one of the causes of WWI because European nations were looking to regain their lost territories. Militarism is a nation`s policy to maintain strong army forces. This was also another cause to WWI because France, Russia, and Germany were competed to build powerful armies. The assassination of Franz Ferdinand was probably the first cause of WWI. Franz Ferdinand was the heir to the throne of archduke of Austria. He was assassinated by a Serbian nationalist. This led to the Austrian-Hungarian empire to declare war on Serbia. After that Serbia had it`s friends to help them out, but so did Austria-Hungary.
