In 1916, two diplomats Sir Mark Sykes of Britain and François Georges-Picot of France sat over a map of the Ottoman Empire and drew a line. With a pencil, they divided the Arab provinces into zones of future control: the British would take what became Iraq and Jordan, the French would take Syria and Lebanon. The line was arbitrary, cutting through tribal lands and ethnic enclaves, but it would become the border of four modern states.
That single stroke, and the wars that followed, transformed the Middle East from a multi-ethnic empire into a mosaic of nation-states. World War I destroyed the Ottoman Empire; World War II destroyed the European empires that replaced it. Each war left an indelible mark on the region’s borders, politics, and conflicts that still shape headlines today.
The Fall of the Ottomans: A World Drawn by Pencils
For 400 years, the Ottoman Empire ruled the Middle East from Istanbul. Its collapse in 1918 was not sudden—it had been crumbling for decades—but the war delivered the final blow. When the empire dissolved, the Allies, led by Britain and France, were left to decide the region’s fate.
The Sykes-Picot Agreement of 1916 was the blueprint. It was a secret pact, revealed to the world only when the Bolsheviks published it after the Russian Revolution. The agreement divided the Ottoman Arab provinces into British and French zones, with a nod to Russian interests in the north. The borders it drew ignored the region’s ethnic and religious mosaic. Kurds found themselves split among Turkey, Iraq, Syria, and Iran. Shiite and Sunni Arab communities were merged into new states that had never existed before.
The League of Nations formalized this division in 1920 with the mandate system, a euphemism for colonial rule. Britain took mandates for Iraq, Palestine, and Transjordan; France took Syria and Lebanon. The mandates were supposed to prepare these territories for self-governance, but in practice, they were colonies with a veneer of international oversight.
One declaration from 1917 cast a long shadow: the Balfour Declaration, in which Britain expressed support for a “national home for the Jewish people” in Palestine. At the time, Palestine was 90 percent Arab and 10 percent Jewish. The declaration, which contradicted British promises to Arab leaders during the war, sowed the seeds of a conflict that would erupt decades later.
The Birth of New States and the Rise of Turkey
Out of the Ottoman wreckage, new states emerged, often with rulers chosen by the colonial powers. The Hashemite dynasty, which had led the Arab Revolt against the Ottomans, was rewarded with thrones in Iraq and Transjordan. The French, meanwhile, carved Syria and Lebanon out of the Levant, favoring the Maronite Christians in Lebanon and the Alawite minority in Syria—a policy of divide and rule that would have lasting consequences.
The borders were artificial, and the populations were not consulted. As the British diplomat T.E. Lawrence famously said, the lines were “drawn by the pencil of a diplomat, not by the sword of a soldier.” The result was a legacy of instability: nations whose borders did not align with ethnic or tribal loyalties.
Not all of the Middle East fell under mandate rule. The Turkish War of Independence (1919–1923), led by Mustafa Kemal Atatürk, expelled Greek and Allied forces from Anatolia and established the Republic of Turkey. Atatürk abolished the Caliphate in 1924, ending a 1,300-year institution that had symbolized Muslim unity. Turkey emerged as a secular, nationalist state—a model that would inspire other Middle Eastern leaders.
World War II: The End of Empire
World War II devastated Europe, leaving Britain and France financially exhausted and militarily weakened. The war also brought the Middle East into sharper focus as a strategic prize. Oil, discovered in the region in the early 20th century, had become essential for modern warfare. The Suez Canal, controlled by Britain, was the lifeline to India and the East.
The war accelerated Jewish immigration to Palestine, driven by the Holocaust. Between 1939 and 1948, the Jewish population of Palestine doubled, intensifying Arab-Jewish tensions. In 1947, the United Nations proposed a partition plan, dividing Palestine into Arab and Jewish states. The Arab leadership rejected it; the Jewish leadership accepted it. On May 14, 1948, Israel declared independence, and the first Arab-Israeli War began the next day.
The war was a catastrophe for Palestinian Arabs, who called it the Nakba, or “catastrophe.” Around 700,000 Palestinians were displaced or fled from their homes, becoming refugees in neighboring countries. The state of Israel survived, but the conflict became a defining issue of Middle Eastern politics for decades.
The Cold War and the Rise of Nationalism
As the European empires withdrew, the United States and the Soviet Union moved in, turning the Middle East into a Cold War battleground. Each superpower sought allies, offering military aid, economic support, and diplomatic protection in exchange for influence. The region’s oil reserves made it a prize worth competing for.
Arab nationalism, already a potent force, surged in the decades after World War II. Leaders like Gamal Abdel Nasser of Egypt, who came to power in a 1952 coup, championed secular pan-Arabism—the idea that all Arabs should unite in a single state or bloc, free of colonial influence. Nasser’s rhetoric inspired millions, but his dreams of unity were thwarted by the very borders the Sykes-Picot Agreement had drawn.
Oil became the lever for economic sovereignty. Iran nationalized its oil industry in 1951, taking control from the Anglo-Iranian Oil Company. The move was a direct challenge to British power, and it was met with Western retaliation—a CIA-backed coup in 1953 restored the Shah and reversed the nationalization. But the genie was out of the bottle: other oil-producing states began to demand a greater share of profits and control.
The Suez Crisis of 1956 was the final nail in the coffin of Anglo-French dominance. When Nasser nationalized the Suez Canal, Britain, France, and Israel invaded Egypt. The United States and the Soviet Union, both opposed to the invasion, pressured the three powers to withdraw. The humiliating retreat marked the definitive end of Britain’s and France’s imperial era in the Middle East.
A Region Redrawn: From Empires to Nation-States
By the 1960s, the Middle East was unrecognizable from the Ottoman era. The multi-ethnic empires that had ruled the region for centuries were replaced by a system of sovereign nation-states with fixed borders. The colonial powers were gone, replaced by new actors: the United States, the Soviet Union, and a new generation of Arab leaders.
The legacy of the two world wars is a double-edged sword. On one hand, the nation-states that emerged brought a new form of political identity—nationalism—that gave people a sense of belonging and self-determination. On the other hand, the borders drawn by colonial powers and the conflicts that followed have left a volatile legacy. The Israeli-Palestinian conflict, the Kurdish question, and the sectarian tensions in Iraq and Syria all trace their roots to the decisions made in the aftermath of the wars.
The Middle East today is a product of the 20th century’s wars, but it is not a passive product. The people of the region have reshaped the structures imposed on them, sometimes violently, sometimes peacefully. The remaking of the Middle East is not a finished story; it continues to unfold in every border dispute, every movement for change, every negotiation over oil and identity.
The two world wars dismantled the Ottoman Empire and then the European empires that succeeded it, leaving behind a new Middle East. The borders drawn by diplomats in the 1910s and 1920s still define the region, but they are not eternal. The forces of nationalism, religion, and geopolitics continue to strain against those boundaries, a reminder that the remaking of the Middle East is an ongoing process, shaped by the choices of its people.
