When Archduke Franz Ferdinand was killed in Sarajevo, the world did not immediately understand that it was standing on the edge of a war that would become a kind of pestilence. The assassination did not create World War I by itself. It exposed a system already loaded with alliance commitments, imperial insecurity, military timetables, elite arrogance, and leaders who believed escalation could be managed. That is the part of history worth remembering now.
