One clear change
On 28 June 1914, Franz Ferdinand and his wife Sophie were killed in Sarajevo. The subsequent crisis escalated into war. Imperial War Museums’ chronology traces the escalation to Britain’s entry on 4 August.
Our counterfactual changes one fact: the couple survive the attack. It does not substitute a successful bombing for a successful shooting; that would leave the central premise unchanged.
What survival might change
The immediate political crisis would differ. Governments could investigate, threaten, negotiate or still choose confrontation. Survival does not by itself remove military planning, rival ambitions or distrust.
Choose one government decision in the following weeks and explain why it changes. Give the decision-maker a reason based on their position, rather than knowledge of the world wars that followed in our timeline.
Two possible paths
One imagined path could involve a contained diplomatic crisis. Another could involve further escalation despite the failed attack. Present both as possibilities and identify the additional choices needed for each.
Avoid predicting that a surviving archduke guarantees peace for generations. Equally, do not claim that a general war on the same date was unavoidable.
Use the exercise to test causation
Build a short timeline containing real events up to the attack and clearly marked invented events afterwards. Finish with the strongest objection to your preferred outcome. This makes the scenario an argument about contingency rather than a confident description of a future that never happened.
