Mosul Question (1924–1926) was a diplomatic and territorial dispute over the former Mosul Vilayet after the collapse of the Ottoman Empire that involved the United Kingdom, the Republic of Turkey, and the nascent Kingdom of Iraq. The contest combined claims tied to the Treaty of Sèvres, the Treaty of Lausanne, and wartime arrangements, and it attracted adjudication by the League of Nations and active diplomacy by figures such as Lord Curzon, Mustafa Kemal Atatürk, and Gertrude Bell. The outcome shaped borders in Upper Mesopotamia and influenced subsequent Iraqi–Turkish relations and energy politics in the Middle East.

Background

The dispute followed the disintegration of the Ottoman Empire after World War I and the imposition of mandates under the Treaty of Sèvres, supplanting Ottoman administrative units like the Mosul Vilayet and the Kurdistan Vilayet. The Sykes–Picot Agreement and wartime commitments made by the British Empire intersected with nationalist claims advanced by Mustafa Kemal Atatürk during the Turkish War of Independence, while local dynamics involved Kurdish tribal leaders and the diverse communities of Mosul including Assyrians, Armenians, and Arabs. British strategic priorities—linked to the Baghdad Railway, Royal Air Force control, and access to presumed oil fields near Kirkuk—shaped policy pursued by the British Government and administrators such as Sir Percy Cox and Gertrude Bell.

Diplomatic Negotiations and Claims

Negotiations featured competing legal and historical claims presented by the Republic of Turkey and the United Kingdom on behalf of Kingdom of Iraq. Turkish negotiators invoked the continuity of Ottoman sovereignty over the Mosul Vilayet and referenced the provisional boundaries in the Treaty of Lausanne, while British representatives argued for incorporation into Iraq based on wartime occupation and administrative control exercised by the British Mandate for Mesopotamia and the Anglo-Iraqi Treaty (1922). Prominent diplomats included Lord Curzon and representatives of the Foreign Office, alongside Turkish envoys associated with Ankara and the Grand National Assembly. Regional actors such as Sheikh Mahmud Barzanji and tribal leaders of Kurdistan complicated claims by asserting local autonomy and influencing British calculations.

League of Nations Involvement

Unable to resolve differences bilaterally, parties referred the dispute to the League of Nations, which established a commission to investigate the demographic, economic, and legal aspects of the region, drawing on expertise from scholars and officials linked to institutions in Geneva, Paris, and London. The League of Nations Commission on Mosul examined population statistics, the location of oil prospects near Kirkuk, and the implications for minority protections involving Assyrians and Armenians, producing recommendations that balanced Turkish sovereignty claims against British strategic interests. International figures and delegations from France and other member states observed proceedings, and the commission’s report informed the subsequent negotiations that led to a League-mediated settlement.

Military and Local Responses

The period saw localized military posturing and incidents involving units associated with the Royal Air Force and Turkish irregulars operating in border districts, while Iraqi forces under the monarchy coordinated with British advisors to assert control. Kurdish tribes and urban notables in Mosul and Kirkuk responded variably, with some leaders aligning with Ankara and others with the British Empire or the Iraqi monarchy, as exemplified by uprisings and negotiations led by figures such as Sheikh Mahmud Barzanji. The memory of campaigns like those during World War I and the Assyrian Levies informed fears of displacement and intercommunal violence, prompting international attention to security guarantees and minority rights.

Settlement and Aftermath

In 1926 a settlement was reached that effectively assigned the former Mosul Vilayet to the Kingdom of Iraq under guarantees and financial arrangements mediated by the League of Nations, culminating in the Ankara Agreement (1926) and a British-Turkish accord recognizing Iraqi sovereignty in exchange for compensation and concessions to Turkey. The resolution integrated oil-producing areas such as Kirkuk into Iraq, influencing the structure of concessions involving companies connected to Anglo-Persian Oil Company interests and shaping later rivalries over petroleum. The settlement included provisions for minority protections and transit rights and was registered with intergovernmental bodies in Geneva, though it left unresolved grievances in Ankara and among Kurdish populations that contributed to future tensions.

Impact on Iraqi-Turkish Relations

The adjudication of the Mosul issue recalibrated bilateral relations between Ankara and Baghdad and redefined interactions with former imperial powers such as the United Kingdom and France. While formal recognition reduced the immediate risk of large‑scale conflict between the Republic of Turkey and the Kingdom of Iraq, lingering irredentist sentiment in Turkish politics and nationalist circles influenced diplomatic exchanges during the interwar period, involving leaders like Mustafa Kemal Atatürk and statesmen in Iraq such as King Faisal I. The settlement also affected border management, cross-border tribal relations in Kurdistan, and subsequent treaties, and it set precedents for League of Nations arbitration that resonated in later disputes over mandates and frontier delineation.
