Cause of WWI

World War I was the the first big war. This war started with Imperialism, when countries were fighting over territory in Europe. This than cause the triple alliance and the triple Entente. The triple alliance included the Germany, Italy and Austria-Hungary. The triple entente included the France, Russia and England. They competed over territory. Militarism was the power each these nations had in military. Francis Ferdinand and his wife visited Sarajevo on June 28, 1914, it was their last visit to anywhere as they were shot by Serbians. Australia then made this assassination an excuse to start WWI. Nationalism then showed in the triple alliance and triple entente as they go on to war. Once Australia attack Serbia, Russia attacked Australia because Russia was in alliance with the Serbian. This then led other nations into this war causing it to be the 1st great war.
