## Introduction

At the start of the twentieth century, Western Europe stood at the center of global power. European states controlled vast colonial empires, dominated world trade, and shaped diplomacy across Africa, Asia, and the Middle East. This dominance had been built during earlier imperial expansion, but after **1900** it began to weaken.

For AP World History, this topic matters because it is really about a chain of causation: European dominance led to imperial control, imperial control provoked nationalist resistance, and the world wars weakened Europe enough for anti-colonial movements to succeed. By the mid-twentieth century, formal empire was collapsing, even though foreign influence often survived in new forms.

> **Key Term: Western dominance**
> The period in which Western European states, and later the United States, exercised outsized political, military, and economic power over much of the world.

### Why Western Europe was dominant before 1914

By **1914**, European powers controlled most of Africa, large parts of Asia, and major strategic routes such as the **Suez Canal**. Britain had the largest empire, France the second largest, and other states such as the Netherlands and Belgium also ruled overseas territories. This dominance rested on several linked strengths.

First, industrialization gave Europe stronger weapons, bigger navies, and more reliable transport. Second, imperial competition pushed states to seize raw materials, labor, and markets. Third, many Europeans justified empire with ideas of racial superiority and “civilizing” missions.

But dominance was never complete or uncontested. Colonized peoples resisted rule, and some regions experienced only indirect control. Even before **1900**, anti-imperial movements were already forming. That matters because decolonization after **1945** did not come from European weakness alone. It also came from long-building local opposition.

> **Key Term: anti-colonial nationalism**
> A political movement in which colonized peoples demanded self-rule and independence from imperial powers.

A second weakness in European dominance was that imperial powers competed with one another. The same rivalries that built empires also made Europe unstable. By the early twentieth century, alliances, arms races, and nationalist tensions made a major war very likely.

> **Test Tip:** If a prompt asks why empire declined, do not give only one cause. Strong AP answers combine **European weakness**, **colonial resistance**, and **global political change**.

### How World War I began imperial decline

**World War I (1914–1918)** did not end European dominance by itself, but it damaged it badly. The war killed millions, drained treasuries, and exposed the weakness of old empires. Four major empires fell apart: the **German**, **Ottoman**, **Russian**, and **Austro-Hungarian** empires.

This mattered in two ways. First, it showed that huge imperial states were vulnerable to modern warfare and nationalist pressures. Second, it spread the language of **self-determination**, even though that principle was applied unevenly.

European leaders talked about national self-rule at the **Paris Peace Conference**, but they did not apply it consistently to colonized peoples. In Europe, some new states were created. In the Middle East and parts of Africa, however, former Ottoman and German territories were often handed over to Britain and France instead of becoming independent.

> **Key Term: self-determination**
> The principle that peoples should be able to choose their own political status and government.

The contradiction was obvious. European powers claimed to defend liberty, yet still ruled overseas peoples without their consent. Colonial soldiers who had fought in the war returned home with new expectations. They had served empires in battle, so many now demanded rights or independence.

### The mandate system: empire under a new name

After World War I, the **League of Nations mandate system** placed former German and Ottoman territories under the administration of European powers. In theory, these territories were being guided toward independence. In practice, this often meant imperial rule continued under international approval.

Britain received mandates including **Iraq**, **Transjordan**, and **Palestine**. France received **Syria** and **Lebanon**. These were not yet sovereign states in the full sense. Local people often saw mandates as a betrayal because wartime promises had raised hopes of independence.

> **Key Term: League of Nations mandate system**
> A post-World War I arrangement in which former German and Ottoman territories were administered by European powers rather than granted immediate independence.

The mandate system is a good example of continuity and change. Change: the old empires had fallen. Continuity: powerful European states still controlled non-European lands. This is exactly the kind of distinction AP questions reward.

It also helps explain later conflict. In **Palestine**, British rule and earlier promises in the **Balfour Declaration (1917)** helped lay foundations for Arab-Israeli tensions. In other places, European border-making ignored local ethnic, tribal, or religious realities, creating future instability.

> **Test Tip:** If a question asks whether World War I ended imperialism, the best answer is **no**. It weakened empires and changed their form, but mandates show that imperial control continued.

### Why World War II was the decisive turning point

If World War I weakened Europe, **World War II (1939–1945)** delivered the more decisive blow. European states emerged exhausted, indebted, and militarily overstretched. Britain and France had won the war, but they could no longer act like the unquestioned masters of world politics.

The war also discredited imperial claims in moral terms. European empires had long justified rule by claiming superiority and order. Yet the war brought occupation, mass destruction, and genocide to Europe itself. That made imperial boasts about civilization much less convincing.

At the same time, Japan’s wartime victories in Asia damaged the myth that Europeans were unbeatable. Even though Japanese imperialism was harsh and violent, its early success showed many colonized peoples that European rulers could be defeated.

Power now shifted toward two superpowers: the **United States** and the **USSR**. Both opposed old-style European empire at different times and for different reasons. The United States often favored self-rule in principle and open markets. The USSR opposed colonialism as part of its anti-capitalist message. Neither power was purely idealistic, but both helped create a world in which old empires were harder to maintain.

### Decolonization after 1945: different paths to independence

Decolonization did not follow one pattern. Some colonies gained independence through negotiation and political pressure. Others experienced long and brutal wars.

**India** is the classic example of negotiated decolonization, though “peaceful” must be used carefully. British rule ended in **1947** after decades of nationalist pressure led by the **Indian National Congress**, **Mohandas Gandhi**, and **Jawaharlal Nehru**. Gandhi’s nonviolent resistance was important, but so was Britain’s postwar exhaustion. Even so, independence came with **partition**, creating **India** and **Pakistan** and causing massive migration and violence.

**Ghana**, independent in **1957** under **Kwame Nkrumah**, is another major example of relatively peaceful transition. It became a symbol of African nationalism and inspired other colonies south of the Sahara.

By contrast, **Algeria** gained independence from France only after a violent war from **1954 to 1962**. French settler presence made compromise much harder. The **FLN** used guerrilla warfare, and the French state responded with severe repression. This is why settler colonies often saw bloodier decolonization.

Vietnam is another violent case. French defeat at **Dien Bien Phu (1954)** ended French control in Indochina, but Cold War conflict then shaped Vietnam’s future. So even when empire ended, outside intervention often continued.

> **Key Term: decolonization**
> The process by which colonies gained independence from imperial powers, especially after World War II.

The **Congo**, independent from Belgium in **1960**, shows a third pattern: rapid independence followed by crisis. Belgium had done little to prepare Congolese political leadership. Soon after independence, the country descended into instability, and Cold War powers became involved. This makes Congo a major counterexample to any simple story that independence automatically brought order.

### Suez, Bandung, and the new postcolonial world

Three major developments show how global politics changed after empire began to fall.

The first is the **Bandung Conference (1955)**. Leaders from Asian and African states met in Indonesia to promote solidarity, oppose imperialism, and discuss how to avoid dependence on either Cold War bloc. Bandung did not create the **Non-Aligned Movement**, but it prepared the way for it.

The second is the formal creation of the **Non-Aligned Movement (1961)**. Leaders such as **Nehru**, **Nasser**, **Sukarno**, and **Nkrumah** wanted recently independent states to avoid becoming pawns of the United States or USSR.

> **Key Term: Non-Aligned Movement**
> A group of states founded in 1961 that sought to avoid formal alignment with either the American or Soviet bloc during the Cold War.

The third is the **Suez Crisis (1956)**. After **Gamal Abdel Nasser** nationalized the Suez Canal, Britain and France, with Israel, attacked Egypt. But they were forced to withdraw under pressure from the United States and USSR. This was a huge symbolic moment. It showed that Britain and France could no longer act independently as dominant imperial powers.

### Imperial decline did not end outside control

One of the most important AP distinctions is between **formal empire** and **neocolonialism**. Many states became politically independent, but still faced foreign economic pressure, outside investment, military intervention, and inherited colonial borders.

> **Key Term: neocolonialism**
> Indirect control of formally independent states through trade, debt, investment, or political influence rather than direct colonial rule.

This is why decolonization is not the same thing as full autonomy. New states often depended on exporting raw materials. Former colonial languages, legal systems, and administrative structures remained. Cold War superpowers frequently interfered in postcolonial politics.

So the biggest continuity after imperial decline was outside influence. The biggest change was the end of direct European rule over most colonies. Strong essays keep both ideas in play at once.
