Austria-Hungary's 1914 Ultimatum to Serbia: Three Demands That Started WWI

Delivered July 23, 1914 (48-hour deadline), the Austro-Hungarian ultimatum to Serbia contained 10 points — but three core demands made acceptance politically impossible for Serbia, ensuring war.

1. Judicial Investigation (Point 4–5)

Demand: Serbia must allow Austro-Hungarian officials to *participate* in the judicial inquiry into Archduke Franz Ferdinand's assassination (June 28, Sarajevo) — effectively granting foreign police power on Serbian soil.
Why unacceptable: Violated Serbian sovereignty, constitution, and judicial independence. Serbia offered full cooperation *through* its own courts — rejected.

2. Punishment of Conspirators (Point 6–7)

Demand: Serbia must suppress all anti-Austrian organizations (Narodna Odbrana, Black Hand), arrest named individuals, and dismiss officers implicated — including Dragutin Dimitrijević (Apis), head of military intelligence.
Why unacceptable: Required Serbia to purge its own military/intelligence leadership at foreign dictation. Apis was a national hero (1903 coup).

3. Prevention of Future Agitation (Point 8–10)

Demand: Censor textbooks/press, remove "subversive" teachers/officers, accept Austro-Hungarian oversight of border control and propaganda suppression.
Why unacceptable: Turned Serbia into a de facto protectorate — ending independent foreign/domestic policy.

Serbia's Response

Accepted 8 of 10 points (including arrest of Princip, condemnation of propaganda). Rejected Points 5–6 (foreign participation in investigation, dismissal of specific officers). Offered Hague Tribunal arbitration.

Austria-Hungary's Calculation

Vienna *wanted* rejection. German "blank check" (July 5) assured support. Declaration of war July 28. Russia mobilized → Germany declared on Russia/France → Britain entered → World War I.

The ultimatum wasn't a negotiation — it was a trap. Three demands made sovereignty the price of peace. Serbia chose sovereignty.
