1J - Expansion and contraction of empire: the impact of the First and Second World Wars
The world wars helped Britain gain territories while weakening its ability to sustain imperial control. Learn why territorial expansion after 1918 coexisted with nationalist pressure, and how wartime changes contributed to withdrawal from India and parts of the Middle East by 1947.
First World War and imperial pressure
Britain fought the First World War as an imperial power, drawing on soldiers, workers, supplies and finance from across its territories. Indian forces served in several theatres, while the Dominions raised armies under their own governments. Imperial resources supported victory, but contributions also strengthened demands that political status should recognise sacrifice.
Britain and its allies conquered German colonies and Ottoman territories. Victory therefore opened opportunities for expansion rather than producing immediate general withdrawal. The war simultaneously increased British debt, disrupted commerce and widened expectations of political reform. More territory and greater governing capacity did not necessarily move together.
In India, the 1917 Montagu declaration promised the progressive development of self-governing institutions. Yet the Rowlatt legislation of 1919 extended emergency powers, and the Amritsar massacre that year intensified distrust. A government presenting reform and using repression could weaken the legitimacy of its own assurances. Wartime support had not guaranteed agreement about what should follow victory.
The Dominions' separate representation in the peace settlement and League of Nations recognised growing international standing. Colonised peoples did not receive comparable equality. This contrast encouraged a question central to imperial politics: if service demonstrated fitness for political responsibility, why did the results vary so sharply between territories?
The war therefore strengthened empire as a military coalition while exposing inequalities within it. It created both new possessions and conditions that made old forms of authority harder to defend.
Mandates and territorial expansion
The League of Nations' mandate system redistributed former German and Ottoman territories after the war. It presented governing authority as an international trust for peoples' welfare and development. Britain consequently gained responsibilities without every territory being described as an ordinary annexed colony.
Mandate
Authority granted under the League of Nations for a state to administer a former German or Ottoman territory, subject to obligations and international supervision.
Britain administered Tanganyika and received parts of Togoland and the Cameroons. South Africa administered South West Africa, while Australia administered former German New Guinea. These Dominion mandates expanded the wider British imperial system, but were not all governed directly from London. The different arrangements matter when identifying who actually exercised power.
In the Middle East, Britain obtained responsibility for Palestine, including the separately administered Transjordan, and exercised the mandatory role in Iraq through treaties and a monarchy. Former Ottoman territories were treated as capable of movement towards independence with assistance. Yet Britain used the arrangements to protect strategic routes, influence and, increasingly, oil interests. International terminology did not remove unequal power.
Mandates thus support an argument that the First World War enlarged imperial reach. They also qualify it: Britain had obligations, faced organised local opposition and could not assume unlimited direct rule. The promise of development towards self-government provided language with which opponents could challenge continuing control. Territorial acquisitions could therefore contain the basis for future demands to end them.
Withdrawal and influence in the Middle East
British retreat in the Middle East was selective and often preserved influence. The Iraqi revolt of 1920 demonstrated the costs of military occupation. Britain supported Faisal as king in 1921 and governed through treaty arrangements, advisers and air power rather than maintaining the original occupation unchanged. Iraq entered the League as an independent state in 1932, but British treaty rights, bases and economic interests remained important.
Egypt's formal independence in 1922 similarly qualified rather than abolished British power. Britain reserved key matters, including defence and the Sudan. The 1936 treaty permitted a continuing British military presence in the Canal Zone. Egypt was not a League mandate, so its change of status must not be confused with Iraq's. Both cases illustrate the difference between formal sovereignty and practical freedom from foreign influence.
Transjordan became an independent kingdom in 1946 while retaining close British military and financial ties. Palestine proved harder to stabilise. British support for a Jewish national home, Arab demands for independence and conflicting commitments generated deep tensions. The Arab revolt of 1936–39, later Jewish insurgency, and the post-war refugee crisis increased the costs and political difficulties of rule.
