How the Ottoman Empire Fell: Six Centuries of Power, Then Nothing

Six Centuries of Power

At its height, the Ottoman Empire controlled three continents. It stretched from the gates of Vienna to the Persian Gulf, from the Crimea to the Sahara. Its capital, Constantinople, was one of the great cities of the world. Its legal and administrative systems were sophisticated enough to govern dozens of different languages, religions, and ethnic groups under one roof for centuries.

By 1923, it was gone. The last sultan slipped out of Istanbul on a British warship, and the Grand National Assembly in Ankara formally abolished a political structure that had defined the Near East for over six hundred years. What happened in between is one of the most consequential collapses in modern history, and the borders it left behind, drawn hastily by outside powers, have been in dispute ever since.

The Long Nineteenth Century Decline

The decline was not sudden. European observers had been calling the Ottoman Empire "the sick man of Europe" since at least the 1820s, when Greece successfully revolted and became the first territory to break away in the modern period. The phrase was reportedly used by Tsar Nicholas I of Russia in a conversation with the British ambassador in 1853, and it stuck, because it captured something real.

The empire faced a structural problem that proved impossible to solve. It needed revenue to fund a modernizing military capable of defending its enormous territory. Modernizing the military required revenue. The economy could not generate enough tax income to close the gap. By the mid-19th century, the Ottoman government was borrowing heavily from European banks, and by 1881 it had effectively gone bankrupt, forced to accept a foreign administration called the Public Debt Administration that managed its finances on behalf of European creditors. This was not occupation, but it was not sovereignty either.

Meanwhile, the empire kept losing territory. Serbia, Montenegro, Romania, and Bulgaria all achieved various degrees of independence through the 19th century, usually with Russian backing and often through wars that the Ottomans lost. Each defeat reduced the tax base and increased the military burden, accelerating the spiral.

The Young Turk Revolution

By 1908, a group of military officers and intellectuals called the Committee of Union and Progress, known in the West as the Young Turks, had had enough of what they saw as the paralysis of Sultan Abdulhamid II's personal rule. They launched a revolution that restored the constitution, which Abdulhamid had suspended in 1878, and forced the sultan to share power. A year later, after a counter-coup attempt failed, they deposed him entirely.

The Young Turks were genuinely modernizing in their ambitions. They wanted a constitutional government, a reformed military, expanded education, and an empire that could compete with European powers. What they lacked was time and coherence. Factions within the Committee disagreed about almost everything, including whether the empire's salvation lay in pan-Islamic unity, pan-Turkish nationalism, or Ottoman civic identity that embraced all ethnic groups.

They also walked straight into a series of disasters. The Balkan Wars of 1912 to 1913 cost the empire virtually all of its remaining European territory in less than a year of fighting. The shock was enormous. A century of slow retreat suddenly accelerated into catastrophe. Cities that had been Ottoman for centuries, including Salonica, the birthplace of Mustafa Kemal and a major center of Jewish and Muslim culture, were lost within months.

World War One: The Fatal Choice

The Young Turk leadership made the decision that ultimately finished the empire when they entered World War One on the side of Germany and Austria-Hungary in November 1914. Their reasoning was not irrational given their position. They needed a great-power patron, and Britain and France had consistently backed their rivals and stripped their territories. Germany was offering an alliance with seemingly strong prospects.

It did not work out. The war went catastrophically on multiple fronts. The British pushed up from Egypt through Palestine and Syria, backed by the Arab Revolt that T.E. Lawrence helped facilitate. Russian forces advanced in Anatolia until the 1917 revolution pulled Russia out of the war entirely. The Gallipoli campaign, where Allied forces tried to knock the Ottomans out of the war quickly by seizing Constantinople, failed, but it consumed enormous Ottoman resources defending it.

The period also saw the Armenian Genocide, one of the 20th century's defining atrocities. Beginning in 1915, the Ottoman government ordered the deportation of the Armenian population of Anatolia, which resulted in mass killing, death marches, and starvation that killed somewhere between 600,000 and 1.5 million people. The government framed this as a wartime security measure against a potentially disloyal population. The evidence of systematic mass murder is overwhelming and accepted by scholars of genocide across the world, though the Turkish state continues to dispute the characterization.

The Partition and Its Consequences

When the Armistice of Mudros ended Ottoman participation in the war in October 1918, the empire was already hollowed out. The sultan's government signed the Treaty of Sevres in 1920, which partitioned Anatolia among Greece, Armenia, France, Italy, and a small rump Turkish state. It was the most humiliating document in Ottoman history.

The Sevres terms never took effect, because Mustafa Kemal refused to accept them. Operating from Ankara with a parliament he controlled, he fought a grinding War of Independence against Greek forces that had landed at Smyrna in 1919 with Allied backing, against Armenian forces in the east, and against French forces in the south. By 1923, he had won. The Treaty of Lausanne replaced Sevres and recognized a Turkish republic with borders that remain in place today.

The settlement involved the largest organized population exchange in history up to that point. Roughly 1.2 million Greek Orthodox Christians were expelled from Anatolia, and around 400,000 Muslims were expelled from Greece. Families whose ancestors had lived in the same towns for centuries were forced out within months. Communities were destroyed that had existed for millennia. The human cost was staggering.

The Arab Lands Carved Up

South of Anatolia, the Ottoman Arab provinces were not liberated by the war. They were redistributed. The Sykes-Picot Agreement of 1916, negotiated in secret by British and French diplomats, had already divided the Arab-speaking regions into spheres of influence. When the fighting ended, Britain took control of Palestine, Transjordan, and Iraq as League of Nations mandates. France took Syria and Lebanon.

The Arab leaders who had joined the revolt against the Ottomans expecting independence were told to wait. Faisal, who had led Arab forces alongside the British and proclaimed himself King of Syria in 1920, was expelled by the French within months. The British eventually gave him the throne of Iraq instead, a country with no prior existence as a political unit.

The borders drawn in this period cut across ethnic, religious, and tribal lines with little regard for the people living there. Iraq was assembled from three Ottoman provinces (Mosul, Baghdad, and Basra) that had distinct populations and no tradition of common governance. The Kurds, who had been promised autonomy under Sevres, received nothing under Lausanne. Palestine became the site of escalating conflict between Jewish immigrants and Arab residents that British policy could not resolve and eventually refused to try.

Why the Collapse Still Echoes

Every major conflict in the Middle East since 1920 has some relationship to what was decided, or left undecided, in the years between the Ottoman collapse and the final drawing of the post-war map. The questions of Kurdish statehood, the status of Jerusalem, the borders of Iraq and Syria, the relationship between Arab nationalism and political Islam, all of these trace back to the choices made in those years.

The Ottoman Empire was not a good government by modern standards. It was authoritarian, occasionally brutal, and deeply unequal in how it treated different populations. But it was also a functioning multiethnic order that had maintained a version of coexistence for six centuries. Its replacement was not liberation. It was a scramble by outside powers that prioritized their own strategic interests over the people who actually lived there.

The sick man of Europe did not die of natural causes. He was carved up while still breathing, and the carving is still being contested today.
