5 Contributing Factors to WW1. I believe that the factors that led the world to World War 1 were Imperialism, Nationalism, Militarism, Alliances and Assassination, as each played its own role in contributing to the beginning of the Great War.

One of the main factors that contributed to the start of World War I was the assassination of Franz Ferdinand in June 1914. Franz was the archduke Austria-Hungary. A Serbian-nationalist terrorist group called the Black Hand claimed responsibility for the assassination. Because of this Austria-Hungary and Serbia were at war which brought in Germany as an ally of Austria-Hungary and Russia as an ally of Serbia. As more and more countries went to war mostly because of alliances it became World War I as we know it today.
