What Was the Sykes-Picot Agreement?

The Secret 1916 British-French Deal

By 1916, the Ottoman Empire had been dying for decades. The British had a name for it: the Sick Man of Europe. What they also had was a plan for what to do with the body.

The Sykes-Picot Agreement was a secret wartime deal negotiated between British diplomat Mark Sykes and his French counterpart François Georges-Picot. In The Making of the Modern Middle East, RealLifeLore explains the basic idea as straightforward in the way that only truly catastrophic ideas can be: Britain and France would divide the Ottoman Empire's Arab territories between themselves once the war was won, with Britain controlling modern-day Iraq and Jordan, France taking what is now Syria and Lebanon, and Palestine falling under some form of international administration — all agreed upon without consulting a single Arab leader, and kept secret from the populations whose entire future it was deciding.

Two men, one map, and the audacity to believe this was a reasonable way to organise a region home to millions of people across dozens of distinct ethnic, religious, and linguistic communities.

How Sykes-Picot Redrew the Ottoman Empire

Arbitrary Lines and Colonial Interests

The Ottoman Empire had governed the Middle East for centuries, and it had done so by suppressing nationalism in favour of a kind of enforced stability. That was fragile, but it was a system that at least reflected the complexity on the ground. The borders it maintained were often administrative conveniences too, but they had evolved over time and carried some relationship to geography and existing power structures.

Sykes-Picot threw most of that out. The new lines were drawn based on two things: where Britain needed strategic access and where France wanted influence. The ethnic and religious patchwork underneath — Kurds, Sunni Arabs, Shia Arabs, Christians, Druze, Alawites, Jews — was treated as a secondary concern at best, and an irrelevance at worst.

According to RealLifeLore, the borders that emerged weren't entirely invented from nothing. They were largely based on older Ottoman administrative divisions, which gives the whole exercise a veneer of geographic logic it doesn't entirely deserve. The problem wasn't just where the lines were drawn. It was that the entire framework assumed these territories would function as coherent nation-states under European tutelage, when in reality they were internally fractured in ways that colonial administrators either didn't understand or chose not to care about.

What's genuinely staggering is how little time was spent on the question of whether any of this was actually workable.

The Immediate Aftermath: Conflicting Promises

Arab Expectations vs. European Agreements

Here's where it gets particularly tangled. Sykes-Picot wasn't even the only promise Britain was making at the same time.

While secretly agreeing to partition the region with France, Britain was also publicly encouraging Arab leaders to revolt against the Ottomans by dangling the prospect of a large, unified Arab state once the war ended. This wasn't a vague implication — it was an active diplomatic campaign. Arab leaders mobilised their populations based on these assurances. The British got their military assistance. The Arabs got betrayed.

And then there was the Balfour Declaration of 1917, in which Britain also expressed support for the establishment of a Jewish homeland in Palestine — a territory it had just agreed to place under international administration as part of Sykes-Picot, and which Arab leaders understood to be part of their promised independent state. Britain had now made overlapping, mutually contradictory commitments to at least three different audiences about the same piece of land.

The postwar treaties attempted to formalise all of this. The Treaty of Sèvres imposed harsh terms on the collapsing Ottoman state, but Turkish military resistance under Mustafa Kemal forced a renegotiation, producing the Treaty of Lausanne in 1923, which set the modern borders of Turkey. Notably absent from both treaties: any meaningful provision for an independent Kurdish state, leaving the Kurds — a distinct people with a distinct language and culture — stateless across four countries, a situation that remains unresolved to this day.

The gap between what was promised and what was delivered is so wide it almost reads like a different kind of war crime.

How Sykes-Picot Created Modern Middle East Borders

Iraq, Syria, Lebanon, Palestine Shaped by One Agreement

The British Mandate of Iraq is perhaps the clearest example of what happens when you ignore the people who live somewhere. The territory Britain assembled combined three distinct former Ottoman provinces: a Kurdish north, a Sunni Arab centre around Baghdad, and a Shia Arab south clustered around the oil-rich regions near Basra. These groups had different languages, different religious traditions, different relationships to authority, and in many cases, different ideas about what kind of political community they even wanted to belong to.

Britain put them together anyway, in part because the oil was distributed across the territory and controlling the whole thing was more convenient than negotiating partial access.

Syria and Lebanon had their own version of this problem. The French mandate carved Lebanon out of greater Syria specifically to create a territory with a Christian majority — a community France had historical ties to — which meant drawing a border that would leave Lebanon perpetually balanced between a large Christian population and a large Muslim one, with smaller Druze and other communities added in. That internal fragmentation had devastating consequences decades later, as Palestinian refugee flows after 1948 and 1967 altered Lebanon's demographic balance and contributed to the conditions that eventually ignited a 15-year civil war.

The discovery of massive oil reserves — disproportionately located in areas populated by marginalised communities or sitting across contested boundaries — added an economic dimension to every existing grievance. It didn't create the instability, but it gave every external power a concrete financial reason to involve itself in it. As explored in this examination of AIPAC's lobbying influence on US foreign policy, the intersection of geopolitical interest and domestic political pressure has consistently shaped how Western powers engage with the region long after the original colonial arrangements were formally dissolved.

The Long-Term Consequences of Sykes-Picot

Unresolved Issues and Regional Instability

The mandates were supposed to be temporary — a transitional arrangement before the territories became independent states capable of governing themselves. In practice, both Britain and France used the mandate period to extract economic benefits, install compliant governments, and suppress nationalist movements that pushed for genuine independence. By the time the mandates formally ended, the states that emerged were independent in a technical sense but deeply structurally compromised.

Iraq had a monarchy imposed on it. Syria went through multiple coups. Lebanon's fragile sectarian power-sharing arrangement was calibrated on a census from 1932 that rapidly became outdated. Palestine never reached a resolution at all — the competing promises Britain had made to Arab and Jewish communities there exploded into open warfare in 1948, with consequences that require no further elaboration given that the conflict is still ongoing.

The Kurdish question also never went away. Spread across Turkey, Iraq, Syria, and Iran, Kurdish populations have spent the decades since Lausanne alternately negotiating for autonomy, being violently suppressed, and in some cases taking up arms. Every attempt at a settlement has been complicated by the fact that granting Kurdish autonomy in one country tends to alarm the governments of the other three.

What makes this particularly grim is that the states created by Sykes-Picot weren't just internally fragile — they were designed in ways that made regional cooperation structurally difficult too. Borders that cut across ethnic and tribal lines meant that internal politics in one country constantly bled into the domestic politics of its neighbours. The instability wasn't an accident or an unforeseen consequence. It was, in a very real sense, baked in from the start.

Sykes-Picot's Legacy in Contemporary Middle East Conflicts

The line between Sykes-Picot and contemporary conflict isn't always straight, and anyone who draws it too neatly is probably oversimplifying. States have had a century to develop their own political cultures, their own internal dynamics, their own reasons for doing what they do. The borders didn't cause every conflict. They did, however, create the specific terrain on which every subsequent conflict has been fought.

Extremist groups like al-Qaeda and ISIS explicitly framed their goals in terms of erasing the Sykes-Picot borders — not because they're geopolitical scholars, but because those borders had become a widely understood symbol of imposed foreign division. The Palestinian displacement that followed the 1948 war was a direct consequence of the contradictory promises Britain made under the mandate system. The Kurdish statelessness that has produced decades of insurgency and repression traces directly to what was left out of the 1923 treaties.

Even relatively recent diplomatic manoeuvres — the Gulf states recalibrating alliances, sectarian proxy conflicts, the question of who gets to claim regional leadership — play out within the structural constraints that Sykes-Picot established. The region's governments are navigating a geopolitical inheritance they didn't choose, and the populations living under them are paying the ongoing costs of decisions made in London and Paris in 1916. For readers interested in how foreign policy decisions generate political consequences far beyond their intended scope, the domestic US political dynamics around executive appointments offer a different but instructive lens on how institutional decisions with narrow origins produce wide and lasting fallout.

One hundred and eight years later, the agreement is still being litigated — in refugee camps, in proxy wars, in UN resolutions, and in the daily lives of people who have never heard the names Sykes or Picot.
