officially the sebirians,black hand gang..this was the 'spark' that set it off they wanted the war,they worked their way up to it and causing the assasination of archbishop fanz Ferdinand and his wife..when the austrians then gave seberia an ultamatium, an ultamatium that was bound to be refused,the austrians also had a role in the causing it ww1 also as the austruans knew the ultamatium was so daft and were hoping it would be refused so they could declare the war which is what happened.
