Sarajevo and the July Crisis
Serbia accepted almost every term of the ultimatum and was invaded anyway — what does that establish?
Option A1 · The origins and course of the First World War, 1905–18 › Key topic 2 · The growth of tension in Europe, 1905–14 — one of 3 lessons in this key topic. Paper 2 Section A — historical investigation: The origins and course of the First World War, 1905–18, key topic 2 (30 marks: 6 · 8 · 16).
Learn Sarajevo and the July Crisis, teach it to an AI pupil, then defend it in a marked debate — this lesson carries all three.
What the specification asks for
“The assassination at Sarajevo and its consequences.

1 · Understand it
28 June 1914
Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, visited Sarajevo on the anniversary of the Battle of Kosovo, a date of enormous significance in Serbian national memory. Six or seven members of Young Bosnia, armed and trained by elements of the Serbian military intelligence organisation known as the Black Hand under Colonel Dimitrijević, were positioned along the route.
The first attempt failed: a bomb bounced off the car and injured officers behind. After a reception the Archduke chose to visit the wounded in hospital; the driver was not told of the change and took a wrong turning, and Gavrilo Princip, aged nineteen, was standing on the corner. He shot Franz Ferdinand and his wife Sophie at close range. Both died within minutes.
The Serbian government's involvement is disputed and was probably indirect: elements of its military intelligence supplied and trained the assassins; the civilian government appears to have had some warning and to have sent an ambiguous and ineffective message to Vienna. Serbia was neither innocent nor proven guilty as a state, and that ambiguity is exactly what Vienna needed.
Five weeks
5 July: Austria-Hungary asks Berlin for support and receives the blank cheque — unconditional backing whatever it decides, with encouragement to act quickly. This is the decision that converts a Balkan crisis into a European one.
23 July: the ultimatum is delivered with a 48-hour limit, drafted to be rejected. Its terms included the suppression of anti-Austrian organisations and publications, the dismissal of named officials, and — the decisive clause — the participation of Austro-Hungarian officials in the judicial investigation on Serbian soil.
25 July: Serbia accepts almost every term, qualifying only the clause on Austrian participation in the investigation, and offers to submit that point to the Hague. Vienna breaks relations within the hour. The Kaiser, reading the reply on 28 July, wrote that every reason for war had disappeared and proposed a halt in Belgrade — after Austria-Hungary had already declared war that morning.
28 July – 4 August: Austria-Hungary declares war on Serbia and shells Belgrade. Russia orders partial and then, on 30 July, general mobilisation, its military advisers insisting that a partial one was technically impossible. Germany's Schlieffen deployment left no room to wait, and it demanded Russian demobilisation, then declared war on Russia on 1 August and on France on 3 August. On 4 August German troops entered Belgium, and Britain, which had guaranteed Belgian neutrality by the Treaty of London of 1839 and had a Cabinet that would not otherwise have united, declared war that evening.
What the Serbian reply establishes
The ultimatum was designed to be rejected — the Austrian foreign minister Berchtold said so — and Serbia accepted nearly all of it. Austria-Hungary went to war anyway, within an hour, and Germany's own emperor thought the pretext had evaporated.
That sequence is the strongest single piece of evidence that Austria-Hungary wanted a war rather than a settlement, and it can be produced in one sentence. It is also evidence about Germany, since the blank cheque of 5 July was given before anybody knew what Serbia would say, and Bethmann-Hollweg pressed Vienna to act before mediation could begin.
It does not establish everything. Russia's general mobilisation was a decision that made German mobilisation near-automatic; Germany's plan required an attack on France through Belgium regardless of French conduct; and the timetables removed days that might have been used. Responsibility is distributed and it is not distributed equally, and saying which parts of that the evidence supports is the AO4 skill this option assesses.
2 · Learn it — the notes
The dates that earn marks
- 28 June 1914
- Franz Ferdinand assassinated by Gavrilo Princip. Why this date: The occasion. Five weeks separate it from the outbreak, and those weeks contain the decisions.
- 5 July 1914
- The German blank cheque to Austria-Hungary. Why this date: Unconditional backing given before the demands were drafted or the reply known.
- 23–25 July 1914
- The ultimatum with a 48-hour limit; Serbia accepts all but one clause; relations are broken within the hour. Why this date: The single most quotable sequence in the option.
- 30 July 1914
- Russian general mobilisation. Why this date: The decision that made German mobilisation, and therefore the invasion of Belgium, near-automatic.
- 4 August 1914
- Germany invades Belgium; Britain declares war. Why this date: The 1839 treaty gave a divided Cabinet the one ground on which it could unite.
The figures, and how far to trust them
- 48 hours — The ultimatum's time limit, chosen so that Serbia could not consult Russia properly.
- All but one clause — Of the ultimatum accepted by Serbia on 25 July.
- 5 weeks — From the assassination to the British declaration of war.
- 19 — Gavrilo Princip's age; too young for the death penalty, he died of tuberculosis in prison in 1918.
The people to place
- Franz Ferdinand — Heir to the throne; had opposed war with Serbia, which is why his death removed a restraint as well as supplying a pretext.
- Gavrilo Princip — Nineteen-year-old member of Young Bosnia who fired the shots.
- Theobald von Bethmann-Hollweg — German Chancellor; conveyed the blank cheque and pressed Vienna to act quickly.
- Leopold Berchtold — Austro-Hungarian foreign minister who drafted the ultimatum to be rejected.
- Edward Grey — British foreign secretary; proposed mediation, was refused, and used Belgium to unite the Cabinet.
How historians disagree
Attributed interpretations, never voiced — the AO4 seam.
- Fritz Fischer: Germany's leaders deliberately used the July Crisis to bring about a continental war they had decided was necessary, and the blank cheque and the pressure on Vienna are the evidence. Contested by Christopher Clark and others, who read the crisis as a collective failure in which several governments took risks they did not understand, and who give more weight to Russian mobilisation and to Serbian conduct..
What students say — and what is actually the case
Not this: The assassination caused the war.
This: Five weeks and a series of decisions separate them, and Franz Ferdinand had opposed war with Serbia. The assassination supplied an occasion for a policy Vienna already held and removed a person who had restrained it.
Not this: The alliances then dragged everyone in automatically.
This: Italy did not join its allies; Britain had no obligation to France; and Austria-Hungary was not obliged to invade. Every entry was a decision taken by identifiable people, which is why the July Crisis rewards close study.
Two things students merge
Blurred: Occasion and cause.
The distinction: The assassination is the occasion; the causes are the Balkan situation, the alliance incentives, the mobilisation timetables and the decisions of the five weeks. Naming that distinction is often the opening move of a Level 4 answer.
Blurred: Mobilisation and war.
The distinction: Mobilisation is the calling up and transport of reserves; it is not fighting. For Germany, whose plan required a rapid strike west before Russia was ready, mobilisation and war had become effectively the same act — which is why Russia's general mobilisation on 30 July was so consequential.
What a Grade 9 answer holds here
A Grade 9 answer treats the ultimatum as a document with a purpose and reads Serbia's reply as evidence about that purpose. A demand designed to be rejected, accepted almost in full and answered with war inside an hour, tells you what Vienna wanted — and the blank cheque, given eighteen days earlier and before anyone knew what Serbia would say, tells you what Berlin was willing to underwrite.
3 · How it is examined
This strand is genuinely set through: Paper 2 Section A (a) (6 marks — “Describe TWO features of EITHER … OR ….”); Paper 2 Section A (b) (8 marks — “How far does Source A support the evidence of Source B about …? Explain your answer.”); Paper 2 Section A (c) (16 marks — “Extract C suggests that …. How far do you agree with this interpretation? Use Extract C, Sources A and B and your own knowledge to explain your answer.”).
What earns marks: The Serbian reply. One sentence — accepted all but one clause and was invaded within the hour — is worth more on the 16-mark interpretation question than a page of narrative, because it is evidence about intention rather than about sequence.
4 · Prove it — the questions
Answered inside Incandio, where a marker checks what a correct answer must contain and tells you which half was missing. The marking stays in the app; the questions are here.
- Describe TWO features of the Austrian ultimatum to Serbia in July 1914. [6 marks · Paper 2 Section A (a)]
- How far does Source A support the evidence of Source B about responsibility for the outbreak of war in 1914? Explain your answer. [8 marks · Paper 2 Section A (b)]
- Describe TWO features of the July Crisis of 1914. [6 marks · Paper 2 Section A (a)]
- Extract C suggests that Germany was mainly responsible for the outbreak of war in 1914. How far do you agree with this interpretation? Use Extract C, Sources A and B and your own knowledge to explain your answer. [16 marks · Paper 2 Section A (c)]
- How far does Source A support the evidence of Source B about the reasons for Britain's entry into the war? Explain your answer. [8 marks · Paper 2 Section A (b)]
Decide it
This lesson feeds a Decide History judgement — a position you commit to, an objection you answer, a criterion you name: Was there a moment in July 1914 when the war could still have been stopped?.
Think you understand it?
Reading is the start. On Incandio a topic counts as mastered only once you have taught it and defended it — the two things a revision guide cannot ask of you.
Incandio this topic → Prove it. Teach it. Defend it. What does “Incandio it” mean?
- Prove it — five questions on Sarajevo and the July Crisis, marked on the spot, that tell you what was missing rather than just what was wrong.
- Teach it — Explain Sarajevo and the July Crisis — what happened, why, and what it made possible — to Ember, an AI pupil who asks the awkward question. Understanding is credited; wording is not required.
- Defend it — Argue Sarajevo and the July Crisis against the historical mind with the strongest claim on it — three rounds, marked against descriptors you can read before you begin.
- Then the exam — 16 authored exam-style questions on this option, marked on Incandio with the mistake you actually made named.
