If it was a Serbian who shot an Austrian, why did Germany, Russia, France and Britain become embroiled in a war? The European countries became involved in the war because of the alliances they had formed with each other - they had promised to support each other in the event of war and war was upon them.
This list of dates shows how Europe slid into war after the murder of Franz Ferdinand.
