After the Ottoman collapse, the oil-bearing vilayet of Mosul (northern Iraq — Kurds, Arabs, Turkmen and Assyrian/Chaldean Christians) was claimed by both the new Turkish Republic and Britain. The Treaty of Lausanne (1923) left the Iraq–Turkey frontier undrawn and sent it to the League of Nations, which awarded Mosul to British-mandate Iraq in December 1925. Parliament debated it hard — and was genuinely divided.
Under the National Pact, Turkey held Mosul to be part of the national homeland — its population was largely non-Arab (Kurds and Turkmen), and Turkey had never conceded it at Lausanne. Turkish forces pressed the frontier militarily in 1924, and (as Viscount Cecil conceded) there was continuing “a certain amount of Turkish pressure.” Some British members worried that dispossessing the Sultan-Caliph and Muslim populations would inflame opinion across the Islamic world.
Britain argued that Iraq could not be a viable state without Mosul, that the frontier was strategically vital against Turkey, and that it had obligations to the Assyrian/Chaldean Christians who had fled Turkish reprisals (about 6,000 in 1924 alone). The Colonial Secretary (Amery) and Lord Cecil maintained that Britain had loyally accepted the League Council's ruling. Oil was officially down-played — yet critics never believed it.
This is the crux you asked about. There was no referendum. Mosul's population was genuinely mixed — a Kurdish plurality, with Arabs, Turkmen and Christian minorities — and self-determination cut in conflicting directions. Instead of a popular vote, the League sent a Commission of Inquiry (1924) to assess the demography and stability on the ground, supplemented by General Laidoner's report on the refugees. The Commission's demographic-and-stability assessment, plus the case for protecting the Christian minorities, underpinned the award to Iraq.
Labour and radical members attacked exactly this. Noel Buxton put the Eastern question in terms of “self-determination,” arguing the inhabitants' wishes were being subordinated to “matters of financial interest.” The deepest charge came from Mr. Thurtle on the Anglo-Iraq Treaty:
“…the League is being used, not for the purpose of administering justice, but for the purpose of fostering the interests of the strong as against the interests of the weak… this decision is in a direct line with the famous decision in regard to Corfu.”— Mr. Thurtle, Commons, 18 Feb 1926
That comparison to Corfu (Mussolini's 1923 grab, which the League had failed to reverse) was pointed: with Britain a permanent member of the very Council that ruled in Britain's favour, the process looked, to critics, like great-power self-dealing dressed as international law.
Officially, no. Captain Cazalet insisted the Mosul oil was unproven and would need a £10,000,000 pipeline to the Mediterranean to be worth anything — “no one has ascertained whether or not the oil is there in sufficient quantities.” But the defenders gave the game away as often as the critics. Commander Fanshawe, defending the treaty on grounds of “national honour,” recalled that the whole 1915 campaign had begun “for the purpose of guarding a very valuable asset — the pipe line to the oilfields.” Colonel Wedgwood, attacking the cost (£137 million since the Armistice), tied the “recent occupation of Mosul” directly to meeting “the Turkish menace.”
Sharply — and not cleanly on party lines. The Conservative government (Amery, Cecil, Fanshawe) defended the award as honour, obligation and strategic necessity; a young Captain Anthony Eden urged the House to treat it constructively as “two separate decisions.” Sir Alfred Mond raised a lawyer's doubt — whether the League Council had exceeded the narrow boundary-delimitation that Lausanne actually referred to it. On the other side, Major Attlee mocked the Conservatives' contradictions as a “mirage,” while Kenworthy and Wedgwood condemned the whole Mesopotamian commitment as costly imperial overreach foisted on taxpayers who “never had an opportunity of understanding, much less of controlling” it.

| 1901-05-17 | Commons | TURKEY—MASSACRES OF CHRISTIANS AT MOSUL. THE UNDER SECRETARY OF STATE FOR FOREIGN AFFAIRS (Viscount CRANBORNE, Rochester) “: The British Consular Agent at Mosul reported towards the end of April that 10,000 Kurds had gone to the Tiyari mountains with the intention of robbing and killing Christians, of whom fifteen were said to have been already massacred. His Majesty's Ambassador at Constantinople at once brought the matter to the notice of the Porte, and was informed that peremptory instructions had been sent to the local authorities to hold the Kurds in check, and to prevent outrages. Sir N. O'Conor has since been informed by the Turkish Government that there had been a long-standing feud between the people of T…” | view debate ↗ |

YOXALL (Nottingham, W.) “: I beg to ask the Under Secretary of State 446 for Foreign Affairs if information has reached the Foreign Office concerning a massacre of Christians by Kurds in the Tiyari district, vilayet of Mosul; whether a Kurdish chief named Reschid Bey, after murdering fifteen Christians in the said district, has, with 1,000 Kurds, withdrawn to the mountains, with the object of attacking other Christians; and whether any representations to the Porte have been or will be made.” | view debate ↗ |
| 1920-06-25 | Lords | Mesopotamia. VISCOUNT MILNER “: I will tell him the reasons why I think he is rather pessimistic. The large military force at present in Mesopotamia is always set down to Mesopotamia itself. I do not think we can look at the position from that narrow point of view. As a matter of fact, if you take the whole of our forces at present available in the Middle East, which is the centre of almost universal disturbance at the present moment, they are very far from being in excess of what we should in any case be obliged to keep up until not only peace with Turkey had been signed, but something like peace actually existed in those…” | view debate ↗ |

THE MARQUESS OF CREWE “: My Lords, I desire to make a few observations in reply to the statement which the noble Earl has made in answer to the Questions put to him by Lord Islington. I am quite sure that both my noble friend and the House generally will be grateful to the noble Earl for having made so fall and so careful an answer with a view of abating, even if he could not entirely remove, the feeling of uneasiness which, as he very well knows both from what was said here and what was said in another place, has affected a large number of people in this country on the question of Mesopotamia, owing to the convicti…” | view debate ↗ |
| 1922-11-24 | Commons | Foreign Affairs. Mr. NOEL BUXTON “: This question has so far been treated from the political and humanitarian point of view, but we must not forget that it is also connected with another part of the Gracious Speech, namely, that referring to unemployment, because the trade of the Near East has been no mean fraction of the trade which this country has done in the past, and we are faced, if not with the practical extinction at all events with an immense reduction in our exports to countries where we had until lately the premier place, and that has had a repercussion of a serious kind upon unemployment in this country. On that po…” | view debate ↗ |
| 1923-03-20 | Commons | Supply. Lieut.-Commander KENWORTHY “: It has been said again and again from the Front Bench by the former Government— by my right hon. Friend the Member for Carnarvon Boroughs (Mr. Lloyd George). The hon. Baronet voted with him on those occasions, and supported him again and again. We were told that cotton, equal to the best Egyptian cotton, could be grown in Mesopotamia. An attempt was made to bamboozle the electors of Lancashire by talk of that sort. I come to the last reason given, namely, that we have certain pledges to the Chaldeans. This last pledge, which is the most modern one produced to justify our policy in Mes…” | view debate ↗ |
| 1923-03-20 | Commons | Supply. Colonel WEDGWOOD “: An apt illustration, Sir, but I trust that the dissensions in this prospective Cabinet will not be met in the same regrettable manner as were the dissensions in the Emir's Cabinet. Deportations in this country are confined to persons of Irish nationality. This Amendment has a bearing vital to the people of this country. The right hon. Member for Paisley (Mr. Asquith), as long ago as 1921, told the House of Commons that, since the Armistice, we had already spent £137,000,000 on Mesopotamia. Since then two more years have gone by, and in one year we spent £26,000,000 on Mesopotam…” | view debate ↗ |

The SECRETARY of STATE for the COLONIES (Mr. Thomas) “: I have received private notice of two questions on the subject of the position on the Iraq frontier, and with the permission of the House I will make a brief statement covering what has happened there since the House rose. I wish to make it quite clear, at the outset, that there is no question of a state of war existing between this country and Turkey. What has happened is that certain Turkish military movements have taken place on the frontiers of Iraq which His Majesty's 3 Government claim to have been disturbances of the status quo , which both Governments were pledged by the Treaty of La…” | view debate ↗ |

Colonel GRETTON “asked the Secretary of State for Foreign Affairs if the armed Turkish forces which invaded the district of Mosul have withdrawn, if fighting has taken place between the regular forces of the Turkish Government and any British forces stationed in Iraq, and, if so, whether a state of war exists; and if the Turkish forces, either regular or irregular, have not withdrawn, what steps This Majesty's Government has taken to deal with the situation?” | view debate ↗ |
| 1925-12-21 | Commons | Iraq. Captain EDEN “: It is not for nothing that the countries of the Middle East were once the cradle of the human race. Many centuries before this island emerged from a state of barbarism rulers and statesmen were confronted with problems of race and religion, of pride and prejudice, in those lands which we now call Iraq. It is all the more important that, as in the speech of the right hon. Gentleman who has just sat down, we should be able this evening to make suggestions and criticisms that shall be both constructive and helpful. Nothing could be more unfortunate than that we should bring into Debates on this…” | view debate ↗ |

Gentleman replies to invite him to make clear one or two points of importance in this Debate, and also perhaps to make some statement on the general position of Iraq which has not; loomed very largely in the Debate so far as I have heard it. The first point of importance which arises is about our obligation under the Treaty of Lausanne. As far as I understand the sense of that Treaty, although we agreed with Turkey that if we could not come to terms regarding the boundary of Iraq in nine months we would refer the matter to the Council of th…” | view debate ↗ |

When that decision was announced the Colonial Secretary, my right hon. friend Mr. Amery, who has really conducted this case with the greatest skill and discretion, as I am sure everybody will admit when they read what he actually said and not what he is reported to have said, which is not always the same thing, stated that he hoped to submit at an early date a new Treaty whose execution will give final effect to the decision of the Council. He also stated that he accepted the decision of the Council and would loyally conform to it. I do not …” | view debate ↗ |

What happened at the Assembly was this. The Council were asked to appoint a Committee, the name of which was not given but which has now been called the Preparatory Committee for a Conference an Disarmament, which should investigate all t…” | view debate ↗ |

It is about 10 years, ago, since I was first in Iraq, I was not there very long, but there is one feature about Iraq that I remember very well, and it came to my mind in listening to to-day's Debate. It was that curious phenomenon of a mirage—a mirage that made one doubt whether one really saw the sights one seemed to see, but it certainly seemed so with those speakers we have heard tonight.

I submit that the League of Nations, like every other organisation created by human agency, has to stand or fall on its merits, and he would be a very poor friend indeed of the League who suggests that by this Treaty with Iraq and this settlement with Turkey we are doing any good to the League. It is arrangements such as these which tend to bring discredit on the League.
