Franz Ferdinand: How a Sandwich Changed History and Started World War One

The Heir to an Empire

Archduke Franz Ferdinand was not supposed to be heir to the Austro-Hungarian throne. He became the presumptive heir only after the suicide of Crown Prince Rudolf in 1889 and the death of his own father in 1896. He was a complicated man — conservative, deeply religious, prone to rages, but also genuinely progressive in his political thinking. He favoured a restructured empire that would give greater autonomy to its Slavic peoples, a position that made him simultaneously feared by Serbian nationalists and suspicious to hardliners within his own government.

On 28 June 1914, Franz Ferdinand and his wife Sophie were visiting Sarajevo, the capital of Bosnia — a province Austria-Hungary had annexed in 1908, to the fury of Serbian nationalists who believed Bosnia should be part of a greater Serbian state. The date was significant: the anniversary of the Battle of Kosovo, a date of profound importance to Serbian national identity. It was, in retrospect, an extraordinarily provocative choice of timing for a royal visit.

The Plot That Almost Didn't Happen

The Black Hand — a Serbian secret society with connections to Serbian military intelligence — had organised the assassination plot. Seven conspirators were positioned along the Archduke's planned route through Sarajevo, armed with grenades and pistols. The plan seemed straightforward. In practice it was a comedy of errors that came within inches of failing completely.

The first conspirator lost his nerve as the royal motorcade passed and did nothing. The second, Nedeljko Čabrinović, threw a grenade at the Archduke's open-topped car. The grenade bounced off the folded-back convertible hood and exploded under the following vehicle, injuring several people but leaving Franz Ferdinand unharmed. Čabrinović then swallowed his cyanide capsule — which was old and ineffective — and jumped into the nearby River Miljacka to drown himself. The river was four inches deep. He was pulled out, arrested, and beaten by the crowd.

The remaining conspirators, hearing the explosion and seeing the chaos, assumed the assassination had either succeeded or hopelessly failed. They dispersed. The plot appeared to be over.

The Wrong Turn That Changed the World

Franz Ferdinand, shaken but unhurt, continued with his official programme and then insisted on visiting the injured from Čabrinović's grenade attack at the hospital. His motorcade set off through Sarajevo's streets.

His driver, Franz Urban, did not know the route had been changed. He turned into Franz Josef Street — the original planned route — rather than the new route along the Appel Quay. When the error was pointed out, he stopped the car to reverse. He stopped directly outside Schiller's Delicatessen.

Gavrilo Princip — nineteen years old, a member of Young Bosnia, connected to the Black Hand — had given up on the assassination attempt and gone to buy a sandwich from Schiller's. He walked out of the shop and found the Archduke's car stationary five feet in front of him. He later described being unable to believe what he was seeing.

Princip stepped forward and fired twice. Franz Ferdinand was struck in the jugular vein. Sophie was struck in the abdomen. Both died within the hour.

The Chain Reaction

What followed demonstrated how completely the major European powers had constructed a system designed to turn any significant crisis into a continent-wide catastrophe.

Austria-Hungary, suspecting Serbian government involvement, issued an ultimatum with deliberately unacceptable terms. Serbia accepted most but not all conditions. Austria-Hungary declared war on Serbia on 28 July 1914 — exactly one month after the assassination. Russia, as Serbia's protector and fellow Slavic nation, began mobilising its forces. Germany, bound by treaty to Austria-Hungary, declared war on Russia on 1 August. France, bound by treaty to Russia, was drawn in. Germany invaded Belgium to attack France from the west — bringing Britain into the war under its treaty obligation to protect Belgian neutrality.

Within six weeks of two shots in Sarajevo, all of Europe's major powers were at war.

Was the Assassination the Real Cause of World War One?

Historians have debated for a century whether the assassination caused World War One or merely triggered a war that was already inevitable. The alliance system, the arms race, the imperial rivalries and the military planning that had been accumulating for decades — all of these created the conditions in which a single incident could detonate a continental war.

In this reading, if Princip had failed entirely, another incident would eventually have served the same purpose. The powder keg was already built. The assassination was simply the spark.

Others argue that contingency matters — that different decisions at each stage of the July Crisis could have prevented the war, and that the assassination was not inevitable but genuinely accidental in its ultimate form. A different route. A different driver. A sandwich not purchased. Twenty million people might have lived.

Gavrilo Princip

Princip was nineteen at the time of the assassination — too young under Austro-Hungarian law to be sentenced to death. He received the maximum sentence of twenty years imprisonment and was taken to the Theresienstadt fortress in Bohemia. He developed tuberculosis in prison, and his arm was amputated as the disease spread to his bones. He died on 28 April 1918, aged twenty-three, having lost so much weight that his guards described him as barely recognisable. He did not live to see the end of the war his action had started.

Who Was Franz Ferdinand?

Archduke Franz Ferdinand was a complex and somewhat contradictory figure. As heir presumptive to the Austro-Hungarian throne, he was expected to succeed the elderly Emperor Franz Joseph I, who had been on the throne since 1848. Franz Ferdinand's political views were in some respects more progressive than those of the conservative court around him — he had genuine sympathy for the empire's various nationalities and was an advocate of federal reorganisation that might have given South Slavic peoples greater autonomy within the empire.

He was also deeply conservative in other respects: a devout Catholic, a determined opponent of Hungarian political influence, and a man of considerable personal stubbornness. His marriage to Sophie Chotek, a Czech noblewoman considered insufficiently aristocratic by court standards, had produced lasting personal grievances — he was required to sign away the succession rights of their children, and Sophie was subjected to regular humiliations at court ceremonies. His love for his wife was genuine and well-documented; she died beside him in Sarajevo.

Sarajevo on 28 June 1914

The choice of 28 June 1914 for the Archduke's visit to Sarajevo was itself a provocation that Serbian nationalists noted: it was Vidovdan, St Vitus's Day, the anniversary of the Battle of Kosovo in 1389, when Serbian forces had been defeated by the Ottoman Empire — a date of intense symbolic significance for Serbian nationalism.

The assassination attempt had already failed once that morning. As the Archduke's motorcade drove through Sarajevo, one of the conspirators, Nedeljko Čabrinović, threw a grenade at the car. The grenade bounced off the folded-back convertible hood and exploded under the following car, wounding several people. The motorcade continued to the town hall for the scheduled reception.

After the official reception, Franz Ferdinand insisted on visiting the hospital where those injured by the grenade were being treated. The decision required changing the motorcade route. The lead driver, apparently not informed of the route change, turned onto Franz Josef Street as originally planned. When told of the error, he stopped the car to reverse — directly in front of Gavrilo Princip, who had abandoned his original position and was standing in front of a delicatessen shop.

Princip stepped forward and fired two shots from a distance of about 1.5 metres. The first struck Franz Ferdinand in the jugular vein; the second struck Sophie in the abdomen. Both died within the hour. The incident had a quality of black farce — the conspiracy nearly failed, the driver took a wrong turn, the car stopped in the exact wrong place — that makes the catastrophic consequences seem even more contingent.

The Immediate Aftermath

Franz Ferdinand's death produced an immediate political crisis, but it was not immediately clear that the crisis would lead to war. The initial reaction in Vienna was relatively calm: the Archduke had not been popular with the court or the military establishment, and his death removed a figure who had been an obstacle to Hungarian political influence. Some in Vienna saw the assassination as an opportunity rather than a catastrophe.

What turned a political crisis into a world war was the decision by Austria-Hungary, backed by Germany, to use the assassination as a pretext for a confrontation with Serbia. The July Crisis — the five weeks between the assassination and the outbreak of general war — involved a series of decisions by multiple European governments, each of which contributed to escalation in ways that, individually, might have been reversed but collectively proved irreversible.

The speed with which the assassination of one man produced a global war involving tens of millions of soldiers reflected the extraordinary instability of the European political system in 1914 — an instability produced by the alliance systems, arms races, imperial rivalries, and domestic political pressures that had been building for decades. Franz Ferdinand's assassination was the spark; the conditions for conflagration had been assembled over a generation.
