Map of the Ottoman-Persian border through Kurdish territories as demarcated by the Second Treaty of Erzurum 1847

Introduction

On 31 May 1847, the Ottoman Empire and Qajar Persia signed the Second Treaty of Erzurum — this time under the watchful mediation of Britain and Russia. It was the first serious attempt by the two empires to draw a precise, modern boundary line through their shared frontier — a frontier that ran directly through the heart of Kurdistan. Where previous treaties had treated the border as a broad zone, the Second Treaty of Erzurum imposed the European concept of a fixed, demarcated line. Kurdistan was no longer merely divided — it was being measured, mapped, and permanently fixed in place by international law.

For the Kurdish people, the Second Treaty of Erzurum represents a critical turning point. It was not just a bilateral Ottoman-Persian agreement — it was the moment when European imperial powers inserted themselves directly into the governance of Kurdish frontier territories. Britain and Russia did not mediate for Kurdish benefit. They mediated to protect their own colonial and commercial interests in the region. The Kurdish homeland was being carved up not just by two neighbouring empires, but by the global order itself.

What Was the Second Treaty of Erzurum?

The Second Treaty of Erzurum was signed on 31 May 1847 between the Ottoman Empire and Qajar Persia, with Britain and Russia acting as mediating powers. It was the first treaty between the two empires to attempt a precise demarcation of their shared border — replacing the traditional Islamic frontier concept of hudud (border as a zone) with the modern European concept of a fixed, surveyed boundary line.

The treaty divided the disputed frontier regions between the two empires and established a boundary commission — composed of Ottoman, Persian, British, and Russian representatives — to survey and delimit the entire border. This commission would take decades to complete its work, issuing the Carte Identique in 1869 and continuing to refine the border through multiple protocols until the boundary was finally recognised as an international frontier in 1914.

Key Takeaways

• The Second Treaty of Erzurum introduced the European concept of a precise, surveyed border line to the Kurdish frontier — replacing the traditional flexible frontier zone with a fixed, mapped boundary.

• Britain and Russia mediated the treaty not for Kurdish benefit, but to protect their own imperial and commercial interests — making the Kurdish question an instrument of European great-power politics.

• The boundary commission established by the treaty took nearly seven decades (1847–1914) to complete its work — a testament to the impossibility of drawing a clean line through a living Kurdish homeland.

• Kurdish national consciousness was growing throughout this period — both empires viewed Kurdish identity as a threat, yet neither addressed Kurdish political aspirations in the treaty.

Historical Context: Why a Second Treaty?

The First Treaty of Erzurum (1823) had failed to resolve the underlying border disputes between the Ottoman and Persian empires. Throughout the 1830s, border incidents continued — Kurdish tribal raids, contested tribal allegiances, and commercial disputes (including the Ottoman destruction of Iranian commercial interests at Mohammara/Khorramshahr). Both empires experienced increasing difficulty controlling the Kurds along the frontier, as growing Kurdish national consciousness led to intensified resistance and revolt.

By the 1840s, the situation had brought the two empires to the brink of war again. Britain feared that continued instability would weaken both empires and expose them to Russian territorial expansion. Russia sought to maintain its own influence in the Caucasus and Persia. Both European powers had commercial and strategic interests that required a stable Ottoman-Persian border. They offered to mediate — and the negotiations began in Erzurum in 1842, led on the Persian side by Mirza Taqi Khan Farahani (later the great reformer Amir Kabir) and on the Ottoman side by Enveri Sadullah Efendi.

The Treaty Terms: Drawing a Line Through Kurdistan

The Second Treaty of Erzurum adhered fundamentally to the earlier treaties of Zuhab (1639) and Erzurum (1823) but went further by establishing a boundary commission tasked with surveying and marking the entire frontier with precision. The treaty divided the remaining disputed territories between the two empires and attempted to resolve the question of tribal allegiances by assigning specific Kurdish and Arab tribes definitively to one empire or the other.

The negotiations were fraught with difficulty. The Ottoman government secretly added extra articles to the treaty with British and Russian support, and the two sides disagreed on the meaning of key provisions almost immediately after signing. Fighting broke out over the region around Qotur and Khoy in northwestern Azerbaijan shortly after the treaty was concluded, and the boundary commission encountered repeated political setbacks. The Carte Identique — the agreed border map — was not issued until 1869, and full demarcation was not completed until 1914.

Britain and Russia: Imperial Mediators, Not Kurdish Allies

The involvement of Britain and Russia in the Second Treaty of Erzurum is a pivotal moment in Kurdish history. It marks the first time that European great powers directly shaped the governance of Kurdish frontier territories. But Britain and Russia were not acting out of concern for the Kurdish people. Britain feared that border instability would invite Russian expansion southward toward India and the Persian Gulf. Russia sought to maintain influence over Qajar Persia and prevent British domination of the region.

The treaty primarily reflected the economic and imperial interests of London and St Petersburg. The European powers needed a stable, clearly defined frontier to create a legal framework for their own agreements about colonial and commercial rights in the region. Kurdish communities, their political aspirations, and their right to self-determination were irrelevant to this calculation. The Kurdish frontier was being stabilised not for the Kurds, but for the benefit of four empires that had interests in Kurdish territory.

This dynamic — great powers making decisions about Kurdish territory for their own reasons, without Kurdish participation — would intensify through the 19th and 20th centuries, reaching its most destructive expression in the Sykes-Picot Agreement (1916), the Treaty of Sèvres (1920), and the Treaty of Lausanne (1923). The Second Treaty of Erzurum established the template: Kurdish lands as objects of great-power diplomacy, Kurdish people as subjects to be managed, and Kurdish aspirations as irrelevant to the calculations of empire.

Legacy and Significance for Kurdish History

The Second Treaty of Erzurum is one of the most important treaties in Kurdish history because it transformed the partition of Kurdistan from a political arrangement into a legal and cartographic reality. Previous treaties had divided Kurdistan between empires, but the borders were vague zones that Kurdish communities could still navigate. The Second Treaty of Erzurum drew a precise line — surveyed, mapped, and internationally recognised — that could not be crossed, negotiated, or ignored.

The treaty also established the precedent of European great-power involvement in Kurdish affairs. From 1847 onward, the Kurdish question was no longer just an Ottoman-Persian issue — it was a matter of international diplomacy, shaped by the interests of Britain, Russia, and later France and the United States. This dynamic would produce the Sykes-Picot Agreement, the Treaty of Sèvres, and the Treaty of Lausanne — each one further dividing Kurdistan in the service of foreign interests.

Perhaps the most telling detail is that the boundary commission took 67 years to complete its work (1847–1914). Drawing a line through Kurdistan was so difficult, so contested, and so resisted by the Kurdish communities who lived there that it required seven decades of surveying, negotiation, and conflict to achieve. The commission’s struggle is itself a testament to the reality that the Kurds never accepted the borders imposed upon them — and that no line on a map has ever been able to contain a people’s identity.

How long did it take to draw the border?

The boundary commission established by the treaty took 67 years (1847–1914) to complete its work. The Carte Identique was issued in 1869, but full demarcation was not achieved until 1914 — on the eve of World War I.
