Officially we can blame Austria Hungary for causing Great War, because they declared war on Serbia, Russia honored her promise to defend Serbia, which in turn made Germany honor her promise to defend Austria, which in turn activated the Triple Entante between France, Britain, and Russia. When Austrians delivered an ultimatum to Serbia an ultimatum that was almost guarantied to be turned down by Serbia, because it was not possible to accomplish it. Then the Austrians used this case as an excuse to declare war on Serbia after Serbia turned down the ultimatum. However, if there would not be alliance systems then the Great World war would not start just because of this conflict between Austria Hungary and Serbia.

I believe that Germany was most to blame for causing Great War. There were many reasons why we can blame Germany. Germany had many conflicts with greatest European countries. After Franco Prussian war Germany had taken Alsance and Lorraine form France and France wanted to revenge. Germans was nationalistic and wanted their country to become the greatest power in Europe and to reach the aim Germany needed colonies and strong navy to challenge and overtook Great Britain. That is why German relations with France and Britain become so uptight, because Great Britain and France had the most useful colonies while Germany had useless territories in Africa and Pacific.
