In the early hours of July 29, 1914, Czar Nicholas II of Russia and his first cousin, Kaiser Wilhelm II of Germany, begin a frantic exchange of telegrams regarding the newly erupted war in the Balkan region and the possibility of its escalation into a general European war.
One day prior, Austria-Hungary had declared war on Serbia, one month after the assassination in Sarajevo of Austrian Archduke Franz Ferdinand and his wife by a Serbian nationalist. In the wake of the killings, Germany had promised Austria-Hungary its unconditional support in whatever punitive action it chose to take towards Serbia, regardless of whether or not Serbia's powerful ally, Russia, stepped into the conflict. By the time an ultimatum from Vienna to Serbia was rejected on July 25, Russia, defying Austro-German expectations, had already ordered preliminary mobilization to begin, believing that Berlin was using the assassination crisis as a pretext to launch a war to shore up its power in the Balkans.
The relationship between Nicholas and Wilhelm, two grandsons of Britain's Queen Victoria, had long been a rocky one. Though Wilhelm described himself as Victoria's favorite grandson, the great queen in turn warned Nicholas to be careful of Wilhelm's "mischievous and unstraight-forward proceedings." Victoria did not invite the kaiser, who she described to her prime minister as "a hot-headed, conceited, and wrong-headed young man," to her Diamond Jubilee celebration in 1897, nor her 80th birthday two years later. Czar Nicholas himself commented in 1902 after a meeting with Wilhelm: "He's raving mad!" Now, however, the two cousins stood at the center of the crisis that would soon escalate into the First World War.
"In this serious moment, I appeal to you to help me," Czar Nicholas wrote to the kaiser in a telegram sent at one o'clock on the morning of July 29. "An ignoble war has been declared to a weak country. The indignation in Russia shared fully by me is enormous. I foresee that very soon I shall be overwhelmed by the pressure forced upon me and be forced to take extreme measures which will lead to war." This message crossed with one from Wilhelm to Nicholas expressing concern about the effect of Austria's declaration in Russia and urging calm and consideration as a response.
After receiving the czar's telegram, Wilhelm cabled back: "I...share your wish that peace should be maintained. But...I cannot consider Austria's action against Serbia an 'ignoble' war. Austria knows by experience that Serbian promises on paper are wholly unreliable. I understand its action must be judged as trending to get full guarantee that the Serbian promises shall become real facts...I therefore suggest that it would be quite possible for Russia to remain a spectator of the Austro-Serbian conflict without involving Europe in the most horrible war she ever witnessed." Though Wilhelm assured the czar that the German government was working to broker an agreement between Russia and Austria-Hungary, he warned that if Russia were to take military measures against Austria, war would be the result.
The telegram exchange continued over the next few days, as the two men spoke of their desire to preserve peace, even as their respective countries continued mobilizing for war. On July 30, the kaiser wrote to Nicholas: "I have gone to the utmost limits of the possible in my efforts to save peace....Even now, you can still save the peace of Europe by stopping your military measures." The following day, Nicholas replied: "It is technically impossible to stop our military preparations which were obligatory owing to Austria's mobilization. We are far from wishing for war. As long as the negotiations with Austria on Serbia's account are taking place my troops shall not make any provocative action. I give you my solemn word for this." But by that time things had gone too far: Emperor Franz Josef had rejected the kaiser's mediation offer, saying it came too late, as Russia had already mobilized and Austrian troops were already marching on Serbia.
The German ambassador to Russia delivered an ultimatum that night—halt the mobilization within 12 hours, or Germany would begin its own mobilization, a step that would logically proceed to war. By four o'clock in the afternoon of August 1, in Berlin, no reply had come from Russia. At a meeting with Germany's civilian and military leaders—Chancellor Theobald Bethmann von Hollweg and General Erich von Falkenhayn—Kaiser Wilhelm agreed to sign the mobilization orders.
That same day, in his last contribution to what were dubbed the "Willy-Nicky" telegrams, Czar Nicholas pressed the kaiser for assurance that his mobilization did not definitely mean war. Wilhelm's response was dismissive. "I yesterday pointed out to your government the way by which alone war may be avoided....I have...been obliged to mobilize my army. Immediate affirmative clear and unmistakable answer from your government is the only way to avoid endless misery. Until I have received this answer alas, I am unable to discuss the subject of your telegram. As a matter of fact I must request you to immediatly [sic] order your troops on no account to commit the slightest act of trespassing over our frontiers." Germany declared war on Russia that same day.
