The origins and course of the First World War, 1905–18 · Option A1 · Paper 2 Section A — historical investigation

Key topic 2 · The growth of tension in Europe, 1905–14

What a Grade 9 answer knows here. The July Crisis lasted five weeks and every participant had exits available. Treating 1914 as an inevitable explosion removes the decisions — and the decisions are where the marks are, because Level 4 wants criteria applied, not a chain of dominoes described.

Every lesson here ends the same way: learn it, teach it to an AI pupil who asks the awkward question, then defend it against the thinker with the strongest claim on it — free · no account needed.

3 lessons, each answering one essential question with the story, the dates that earn marks, the people to place, how historians disagree and the cap in the mark scheme that bites. Completely free.

The 3 lessons

Balkan nationalism, the Bosnian Crisis and the Balkan Wars

Why did Russia's climbdown in 1908 make its refusal to climb down in 1914 more likely? The Ottoman Empire had been retreating from the Balkans for a century and its remaining European territory was the prize.

Examined through causation and change. Learn Balkan nationalism, the Bosnian Crisis and the Balkan Wars →

Why did two German attempts to break the Entente both make it stronger? France had been given a free hand in Morocco under the Entente Cordiale of 1904.

Examined through causation and consequence. Learn the naval race and the Moroccan Crises →

Sarajevo and the July Crisis

Serbia accepted almost every term of the ultimatum and was invaded anyway — what does that establish? 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.

The dates that earn marks in this key topic

Two from each lesson, in the order the topic is taught — each with the reason it is worth a mark, and the lesson that places it.

1903 — The coup in Belgrade brings an anti-Austrian dynasty to power.
Serbia's orientation changes, and Austro-Serbian rivalry becomes the central Balkan problem. (Balkan nationalism, the Bosnian Crisis and the Balkan Wars)
1908–09 — Austria-Hungary annexes Bosnia; Germany forces Russia to accept it.
Russia's humiliation, and the reason a second climbdown in 1914 was politically impossible. (Balkan nationalism, the Bosnian Crisis and the Balkan Wars)

Isolation and a British commitment produced by an attempt to prevent both. (The naval race and the Moroccan Crises)

The occasion. Five weeks separate it from the outbreak, and those weeks contain the decisions. (Sarajevo and the July Crisis)
5 July 1914 — The German blank cheque to Austria-Hungary.
Unconditional backing given before the demands were drafted or the reply known. (Sarajevo and the July Crisis)
