The ultimatum of July 23, 1914, was a diplomatic note delivered by the Austro-Hungarian ambassador in Belgrade to the . The issuance of the ultimatum is widely seen as an immediate precursor to the outbreak of World War I in August 1914. The note was Austria-Hungary's response to the assassination of Archduke Franz Ferdinand by Serbia-aligned perpetrators the previous month, following weeks of deliberation.
The text was meticulously constructed to be unacceptable to the Serbian government, thereby ensuring its rejection and thus adding to Austria-Hungary's casus belli. Serbia's response was dismissed by the Austro-Hungarian government.
An agreement between Austria-Hungary and its principal ally, the German Empire,The German Imperial Constitution of 1871 gave the new German state the name Deutsches Reich. had been reached as early as July 7 (see July Crisis). Historian Fritz Fischer describes the Reich's agreement as a "blank check."
General context
The Sarajevo assassination
On June 28, 1914, Archduke Franz Ferdinand, heir to the thrones of Austria and Hungary, was assassinated alongside his wife, Sophie Chotek, while attending Austro-Hungarian Army maneuvers in Bosnia-Herzegovina. The attack, carried out by Gavrilo Princip, a young Yugoslav nationalist, occurred during the couple's visit to Sarajevo, the provincial capital of annexed Bosnia and Herzegovina. Princip's actions were organized by Bosnian Serbs who had been Austro-Hungarian subjects since 1909. The murder was the culmination of a decade of attacks on high Austro-Hungarian officials in the southern Slavic territories of the Dual Monarchy.
The Austro-Hungarian police force investigated the assassination. Their preliminary findings blamed ethnic Serb nationals of the Kingdom of Serbia. The investigators lacked definitive proof in 1914 but, in 1919, after hostilities ended, the involvement of the Serbian secret society The Black Hand was unequivocally revealed .
Austro-Hungarian suspicions Austro-Hungarian authorities suspected the Kingdom of Serbia's role in the attack before their investigation began. Investigators uncovered a plot with conspirators in both Bosnia-Herzegovina and Serbia, and revealed the involvement of the Serbian Black Hand—an organization headed by chief of Serbian military intelligence Dragutin Dimitrijević.
Investigators believed that the perpetrators were aided by Kingdom of Serbia military personnel and border guards in both preparing for the attack and in the exfiltration of accomplices, many of whom were still presumed at large after the assassination. Austrian diplomats in Serbia also observed a discrepancy between official expressions of condolence and the public's reaction to the Archduke's murder. ordinary Serbian citizens were seen to celebrate.
The Dual Monarchy anticipated a major crisis in the Balkan Peninsula months before the assassination. By at least as early as the beginning of 1914, intelligence sources reported that Tsar Nicholas II favored a conflict with the Dual Monarchy, and were certain that the anticipated crisis would erupt before the year's end. Their assessment was corroborated by assets and agents in Bosnia-Herzegovina during the June investigation.
Russia had progressively marginalized Austria-Hungary in the region since the two Balkan Wars. Bulgaria, allied with the Dual Monarchy, suffered a decisive defeat in the Second War.
Serbia, the "Piedmont of the South Slavs" By the turn of the 19th century, Austria-Hungary's eastern and southern possessions were restive, and nationalism was on the rise everywhere.
The Kingdom of Serbia worried Vienna since it had unilaterally declared its independence in 1878. The Serbian Obrenović dynasty had been a client of Austria-Hungary until its violent dissolution in the 1903 May Coup. The new monarch Peter I, with the backing of the Serbian Radical Party, pivoted to a French alliance. Serbia's victory in the Balkan Wars of 1913 only heightened nationalist fervor in Belgrade. Serbia was transforming from a middling state to a rapidly growing power with close ties to Russia; Austria-Hungary and the German Empire were determined to force it back into lockstep with the Central Powers. Meanwhile, the Romanian government in Bucharest, a traditional ally of the Dual Monarchy, was now pivoting to Serbia's position against the Bulgarians, who made no secret of their territorial ambitions in Romania.
Nationalist, ethnic, and religious tensions within the Dual Monarchy also intensified. In 1905, South Slavic representatives in regional assemblies within the Austrian-Hungarian Empire began to form voting blocs in parliaments in Dalmatia and Croatia. In 1908, one such coalition attained a majority in the Sabor (Croatian Parliament) in Zagreb.
In the early months of 1914, Serbia, too, was beset by internal strife. Crown Prince Alexander—who had been made regent because of his father's weakened state—feuded with his military, while Prime Minister Nikola Pašić held de facto executive power. Pašić's participation in the parliamentary elections of August 14, 1914, only exacerbated tensions in Belgrade.
The position of the central powers in 1914 By 1914, the German Empire could no longer keep small Balkan states such as Romania, Bulgaria, and Greece within its orbit. The Balkan Wars had exacted a toll on these kingdoms, and their governments sought financial support from outside sources in rebuilding or in bids to reclaim territories lost to the victors. Neither Germany nor Austria-Hungary offered more than token commitments.The King of Greece only received the marshal's baton in Berlin; he secured credits for his country's much-needed development in London and Paris.
German economic influence in the Ottoman Empire had also been undermined. By the autumn of 1913, the Sublime Porte could no longer secure funding from struggling German banks despite its pro-German stance. Like the Greek king, the Porte turned instead to markets in London and Paris for loans. On May 29, 1914, Karl Helfferich, a representative of Deutsche Bank, sent an alarming memorandum to Chancellor Theobald von Bethmann Hollweg highlighting the Reich's waning status in the Porte. Germany arranged short-term assistance for its dependent allies in June 1914, but its bankers deemed this insufficient to offset future demands on the Reich's treasury.
By the spring of 1914 the Dual Monarchy remained Germany's sole reliable ally; the small Balkan states were increasingly estranged from their erstwhile partners. Vienna's foreign minister, Leopold Berchtold, commissioned a report on developments in the Balkans since the 1913 wars. A draft delivered on June 23, 1914, advised against any alliance with Romania, advocated for a more aggressive stance against Serbia, and supported an alliance with Bulgaria and the Porte against Belgrade. Five days later, Serbian nationalists assassinated the Archduke in Sarajevo.
July 7 – 23, 1914: Intense preparations In the wake of the assassination of Archduke Franz Ferdinand, Austria-Hungary's devised a meticulously orchestrated response in collaboration with the German Reich, aimed at Serbia.In 1914, the Dual Monarchy could not risk a European war alone without the Reich's support.
The German "blank check"
Despite differing perspectives among Austrians and Hungarians, the leaders of the Austro-Hungarian Empire agreed on the importance of seeking counsel from Germany.
On July 2, Austro-Hungarian diplomats were promptly informed of Kaiser Wilhelm II's stance. The German ambassador in Vienna urged Berchtold to act with prudence and cautioned him against hastily assigning blame on the Serbian government.
On July 4, German diplomats briefed their counterparts in Vienna on the Kaiser's position. Wilhelm II conveyed his personal support for his ally in a statement that reiterated positions he had taken the previous autumn.in October 1913, an forced Serbia to withdraw its troops from occupied territories in Albania. He expressed his willingness to back the Dual Monarchy should it take decisive action against Serbia. Support was formally confirmed to the Austro-Hungarian envoy on July 6, 1914.
On July 5, Count Hoyos arrived in Berlin, seeking German support for Austro-Hungarian measures against Belgrade. He carried a handwritten letter from Franz Joseph to Wilhelm II and a memorandum that was highly critical of Serbia.
In the days following the assassination, Wilhelm II had held extensive consultations with his ministers and advisors; their response was to be positive. Reassured by the Kaiser, Hoyos returned to Vienna on July 7. Austro-Hungarian leaders began preparing their measures against Serbia. German officials now urged swift action to capitalize on the outrage sparked by the attack. To limit the oncoming Austro-Serbian conflict, Germany also courted Serbia's potential allies in a bid to steer them away from aiding Belgrade.
Wilhelm II assured the Romanians that the Central Powers would respect their sovereign neutrality in the event of any Austro-Serbian conflict. Bulgaria, the Central Powers' newest member, had recently threatened to invade Romania's southern flank, further guaranteeing Romanian neutrality.
In a statement made on July 21 and 22—one day before the issuance of the ultimatum—Reich Chancellor Theobald von Bethmann Hollweg expressed his view that the Austro-Hungarian note to Serbia was "fair and moderate." On July 24, a circular from the German Foreign Ministry instructed Reich ambassadors to underscore the bilateral nature of the Austro-Serbian dispute.
Moreover, Germany's ambassador in Vienna, Heinrich Leonard von Tschirschky und Bögendorff, exerted considerable influence over the Austro-Hungarian monarchy through his daily interactions and frequent meetings with key policymakers. He advocated for a robust response as a means of restoring the monarchy's waning prestige. It was assumed by officials from both the Reich and Austria-Hungary that a rapid offensive, limited to the capture of Belgrade and its surroundings, would present the Triple Entente with a fait accompli. In the event, however, the Triple Entente was not willing to accept any such outcome.
The different centers of power in Austria-Hungary (July 7–23)
Throughout the crisis, various institutions within the Dual Monarchy exerted contradictory pressures on Austro-Hungarian foreign policy. The common War Minister Alexander von Krobatin, Foreign Minister Berchtold, and Chief of the General Staff Franz Conrad von Hötzendorf all advocated for prompt military action. However, they encountered resistance from Hungarian Prime Minister István Tisza, who did not want the Dual Monarchy to be seen abroad as the aggressor.
Emperor Franz Joseph endorsed a resolute policy towards Serbia. Despite his disinclination towards his slain nephew and successor, the Emperor was determined to safeguard his dynasty and his dominions from any external encroachment. The emperor had the support of powerful friends including Alexander Hoyos, Janos Forgach, Alexander von Musulin, and Franz von Matscheko, as well as the Chief of Staff Conrad von Hötzendorf and Foreign Minister Berchtold. Collectively, these figures exerted considerable influence which enabled the emperor in his confrontation with Serbia. The emperor insisted on establishing the involvement of Serbian intelligence in the assassination to secure Berlin's support before any Austro-Hungarian initiative, and to persuade Tisza to approve military action against the Kingdom of Belgrade.
