Why did the counties enter World War 1?

Answer 1

Initially the war started when a Duke was murdered by a Serbian. Many countries were furious with Germany/Hungary and Austria for their Monarchical rule and unfairness to the other countries. The war escalated as Germany angered many countries over sinking their ships and the Lusitania. The basic problem was the aristocracy and monarch did not care about the general populous or their rights. In the end the imperialistic Monarchs had to give up their countries and adapt differing governing methods and give up land to various people groups.
