Getting Started
The period between the two World Wars (c. 1919–1939) was a time of profound contradiction. While the end of World War I brought ideals of self-determination to the global stage, the reality for most colonized peoples was the continuation of imperial rule. This chapter explores how Western powers and Japan maintained and even expanded their territorial holdings, and how these actions fueled new and more organized forms of anti-imperial resistance.
What You Should Be Able to Do
Explain how imperial control over colonies continued after World War I.
Describe how some imperial states gained new territories despite the war's anti-imperial rhetoric.
Analyze the rise of organized resistance movements in response to colonial rule.
Evaluate the balance between continuity and change in global territorial holdings during the interwar years.
Key Developments & Analysis
This topic is best understood by examining the continuities and changes in the global imperial system from the pre-war era to the late 1930s.
Baseline & Context (c. 1914)
Before World War I, the world was at the peak of modern imperialism. Western European states, particularly Great Britain and France, controlled vast empires spanning Africa, Asia, and the Pacific. At the same time, Japan had emerged as a new, non-Western imperial power, expanding its control over territories like Korea and Taiwan. The global power structure was clearly defined by the relationship between a few powerful imperial states and their many colonial possessions.
Key Changes
The Mandate System: After World War I, the newly formed League of Nations created the mandate system to administer the former colonial territories of the defeated German and Ottoman Empires. A League of Nations mandate was a legal status for certain territories transferred from the control of one country to another following the war. In practice, this system assigned control of these territories—such as former German colonies in Africa and the Pacific, and Ottoman lands in the Middle East—to the victorious powers, primarily Britain and France. This represented a change in the justification for empire, framing it as a temporary trusteeship, but it effectively expanded British and French imperial control.
Growth of Organized Resistance: The ideals of national self-determination, championed during the peace process, inspired and energized colonial populations. This led to a significant change in the nature of anti-imperial resistance, which refers to organized movements opposing foreign rule and colonial exploitation. Resistance became more widespread, politically organized, and nationalist in character. Groups like the Indian National Congress in India shifted from elite debating societies to mass political movements, demanding greater self-governance and, eventually, full independence from British rule.
Key Continuities
Maintenance of Existing Empires: The most significant continuity was that Western and Japanese imperial states predominantly maintained control over their vast pre-war colonial holdings. For hundreds of millions of people living in British India, French Indochina, the Dutch East Indies, and across most of Africa, the end of World War I did not bring independence. The fundamental economic and political structures of colonialism remained firmly in place.
Persistence of Imperial Ideologies: The core beliefs that had justified imperialism—ideas of cultural, racial, and civilizational superiority—did not disappear. While the language of "mandates" suggested a duty to "uplift" colonized peoples, it still operated on the assumption that these populations were not ready for self-rule. This continuity in mindset ensured that the power dynamics between colonizer and colonized remained largely unchanged.

Imperial Holdings: Before and After World War I
| Imperial Power | Key Pre-WWI Holdings (Examples) | Post-WWI Changes & Additions |
|---|---|---|
| Great Britain | India, Egypt, Nigeria, South Africa, Australia, Canada | Gained mandates in the Middle East (Palestine, Transjordan, Iraq) and Africa (Tanganyika). |
| France | Indochina, Algeria, West Africa | Gained mandates in the Middle East (Syria, Lebanon) and Africa (Cameroon, Togo). |
| Japan | Korea, Taiwan, sphere of influence in Manchuria | Gained a mandate over former German islands in the North Pacific (Marshall, Mariana, Caroline Islands). |
Evidence Bank
League of Nations: An international organization founded after World War I to promote peace and cooperation. While intended to prevent future wars, its structure and key policies, like the mandate system, often served the interests of the victorious imperial powers.
Mandate System: The legal framework established by the League of Nations to give Allied powers control over the former colonies of the German and Ottoman Empires. The system divided territories into different classes of mandates, theoretically based on their readiness for self-rule.
Indian National Congress (INC): A political party founded in British India in 1885. In the interwar period, under leaders like Mohandas Gandhi, it transformed into a mass movement that used nonviolent resistance to campaign for greater autonomy and eventual independence from Britain.
Anti-Imperial Resistance: Organized opposition to colonial rule, which grew significantly after World War I. This resistance could take many forms, from political organizing and nonviolent protest (like in India) to armed uprisings in other parts of the world.
Territorial Holdings: Lands and colonies under the control of an imperial power. The continuity of these holdings was a defining feature of the post-WWI global order.
Japanese Imperialism: Japan's expansion into East Asia, which continued and intensified after World War I. Japan's acquisition of a League of Nations mandate and its continued influence in China demonstrated that imperialism was not an exclusively Western practice.
Skill Snapshots
Causation:
The defeat of the Ottoman Empire in WWI → caused the creation of new British and French mandates in the Middle East.
The global discussion of national self-determination → caused an increase in organized anti-imperial movements.
The victory of the Allied powers → caused the transfer of German colonial territories to Allied control under the mandate system.
Comparison:
The mandate system was different from old-style colonialism in its legal justification but similar in its practical application of foreign control.
Japanese imperialism was similar to Western imperialism in its goals of securing resources and international prestige, but different in its geographic focus on East Asia.
The Indian National Congress primarily used nonviolent political protest, which can be compared to more violent armed resistance movements that occurred elsewhere.
Continuity and Change Over Time (CCOT):
Baseline: Around 1900, direct European and Japanese imperial control was the global norm.
Change: The mandate system introduced a new, internationally sanctioned category of territorial control.
Change: Anti-imperial resistance became more politically organized and gained broader popular support.
Continuity: The vast majority of pre-war colonies remained under the firm control of their Western or Japanese rulers.
Common Misconceptions & Clarifications
Misconception: World War I marked the end of colonialism.
- Clarification: For most colonized peoples, the war did not bring independence. It simply reinforced or, in the case of mandates, expanded the reach of the victorious empires.
Misconception: The League of Nations was designed to free colonies.
- Clarification: The League's mandate system was a compromise that ultimately legitimized the transfer of colonial territories to the Allied powers, preserving the imperial system under a new name.
Misconception: Anti-imperialism was a new idea after 1918.
- Clarification: Resistance to colonial rule had existed for centuries. The key change in the interwar period was the growth of organized, nationalist political movements that could mobilize large segments of the population.
One-Paragraph Summary
The era between the World Wars was defined by unresolved tensions between the ideal of self-determination and the reality of persistent imperialism. While World War I dismantled the German and Ottoman Empires, their territories were largely redistributed to the victorious Allies, primarily Britain and France, through the League of Nations mandate system. This system represented a change in the language of empire but ensured the continuity of foreign domination. In response, anti-imperial resistance movements, such as the Indian National Congress, became more organized and gained popular momentum, challenging the legitimacy of colonial rule. Ultimately, the interwar period was characterized by the stubborn persistence of global empires, which in turn sowed the seeds for the major decolonization movements that would erupt after World War II.
