The modern Middle East was forged in the crucible of the First World War, but few know the full story of how war actually came to the region. As Sean McMeekin reveals in this startling reinterpretation of the war, it was neither the British nor the French but rather a small clique of Germans and Turks who thrust the Islamic world into the conflict for their own political, economic, and military ends.

The Berlin-Baghdad Express tells the fascinating story of how Germany exploited Ottoman pan-Islamism in order to destroy the British Empire, then the largest Islamic power in the world. Meanwhile the Young Turks harnessed themselves to German military might to avenge Turkey’s hereditary enemy, Russia. Told from the perspective of the key decision-makers on the Turco-German side, many of the most consequential events of World War I—Turkey’s entry into the war, Gallipoli, the Armenian massacres, the Arab revolt, and the Russian Revolution—are illuminated as never before.

Drawing on a wealth of new sources, McMeekin forces us to re-examine Western interference in the Middle East and its lamentable results. It is an epic tragicomedy of unintended consequences, as Turkish nationalists give Russia the war it desperately wants, jihad begets an Islamic insurrection in Mecca, German sabotage plots upend the Tsar delivering Turkey from Russia’s yoke, and German Zionism midwifes the Balfour Declaration. All along, the story is interwoven with the drama surrounding German efforts to complete the Berlin to Baghdad railway, the weapon designed to win the war and assure German hegemony over the Middle East.

The catastrophe of the First World War, and the destruction, revolution, and enduring hostilities it wrought, make the issue of its origins a perennial puzzle. Since World War II, Germany has been viewed as the primary culprit. Now, in a major reinterpretation of the conflict, Sean McMeekin rejects the standard notions of the war’s beginning as either a Germano-Austrian preemptive strike or a “tragedy of miscalculation.” Instead, he proposes that the key to the outbreak of violence lies in St. Petersburg.

It was Russian statesmen who unleashed the war through conscious policy decisions based on imperial ambitions in the Near East. Unlike their civilian counterparts in Berlin, who would have preferred to localize the Austro-Serbian conflict, Russian leaders desired a more general war so long as British participation was assured. The war of 1914 was launched at a propitious moment for harnessing the might of Britain and France to neutralize the German threat to Russia’s goal: partitioning the Ottoman Empire to ensure control of the Straits between the Black Sea and the Mediterranean.

Nearly a century has passed since the guns fell silent on the western front. But in the lands of the former Ottoman Empire, World War I smolders still. Sunnis and Shiites, Arabs and Jews, and other regional antagonists continue fighting over the last scraps of the Ottoman inheritance. As we seek to make sense of these conflicts, McMeekin’s powerful exposé of Russia’s aims in the First World War will illuminate our understanding of the twentieth century.
