8.5 Decolonization After 1900

Verified for the 2025 AP World History: Modern examCitation:

Defining Decolonization

Decolonization refers to the process through which former colonies—primarily in Asia, Africa, and the Caribbean—gained independence from European imperial powers. This movement accelerated after World War II, as anti-colonial sentiment grew globally and imperial powers faced economic strain and mounting pressure to deconstruct their empires.

The path to independence varied widely. Some countries achieved it through negotiation, while others resorted to armed struggle. Regardless of method, decolonization reshaped global politics, led to the creation of new nations, and forced former imperial powers to redefine their international roles.


Paths to Independence Across the World

India: Nonviolent Resistance and Partition

The independence movement in India had been growing since the early 20th century, especially after Britain failed to grant self-rule following Indian contributions in World War I.

  • The Indian National Congress (INC), led by Mohandas Gandhi, adopted nonviolent methods such as civil disobedience and boycotts to protest British rule.
  • In 1947, India gained independence through negotiation. However, religious tensions between Hindus and Muslims led to the partition of India and Pakistan, resulting in widespread violence and displacement.

Gandhi’s strategy of nonviolent resistance inspired later global civil rights movements and marked a shift in how anti-colonial struggles could be waged.


Ghana (British Gold Coast): Political Organization and Protest

Ghana was the first sub-Saharan African country to gain independence from colonial rule.

  • Kwame Nkrumah, a Western-educated leader, organized the Convention People’s Party to demand self-rule.
  • Through strikes, boycotts, and political mobilization, Ghana negotiated its independence from Britain in 1957, largely without bloodshed.

Kenya: Armed Resistance and Nationalism

Unlike Ghana, Kenya’s path to independence was more violent.

  • The Mau Mau Rebellion (1952–1960) was a nationalist uprising primarily led by the Kikuyu ethnic group against British land policies and colonial rule.
  • Britain responded with brutal military suppression and mass detentions.

Despite the bloodshed, international pressure and continued resistance led to Kenya’s independence in 1963.


Algeria: Guerrilla Warfare Against French Rule

Decolonization in Algeria was among the most violent of the post-WWII era.

  • The National Liberation Front (FLN) launched a guerrilla war against French forces in 1954.
  • The war involved urban bombings, torture, and massacres. French society was bitterly divided over the conflict.
  • Algeria gained independence in 1962 following the Evian Accords and mounting international pressure.

⭐ The Algerian War exposed the deep costs of colonialism and shaped France’s future military and diplomatic strategies.


French West Africa: Political Reform and Gradual Negotiation

In contrast to Algeria, many French colonies in West Africa followed a negotiated path to independence.

  • French policies shifted after WWII, allowing local participation in governance through laws like the Loi-Cadre.
  • By 1960, territories such as Senegal, Niger, and Mali gained independence with limited violence.

Vietnam (French Indochina): Communist Nationalism and War

Vietnam’s decolonization was long and complex:

  • Ho Chi Minh, a communist and nationalist leader, formed the Viet Minh to fight for Vietnamese independence.
  • After defeating the French at the Battle of Dien Bien Phu in 1954, Vietnam was temporarily divided into communist North and anti-communist South.
  • Continued U.S. involvement led to the prolonged Vietnam War, which ended in reunification in 1975.

⭐ Vietnam illustrates how Cold War dynamics influenced decolonization, especially in regions where communism took root.


Nigeria: Federal Independence and Ethnic Tensions

Nigeria, rich in natural resources and home to diverse ethnic groups, gained independence from Britain in 1960.

  • Political tensions soon emerged between regions, especially among the Igbo, Hausa-Fulani, and Yoruba ethnic groups.
  • In 1967, the Igbo-dominated southeast attempted to secede as Biafra, sparking a civil war.
  • The Biafran War lasted until 1970 and resulted in mass famine and deaths.

Angola: Colonial War and Civil Conflict

Angola’s decolonization was part of a broader wave of anti-Portuguese resistance.

  • Independence movements clashed with Portuguese forces starting in the 1960s.
  • Portugal’s Carnation Revolution in 1974 ended authoritarian rule and triggered decolonization.
  • Angola declared independence in 1975, but was immediately plunged into a civil war between rival factions, often backed by Cold War superpowers.

Broader Themes of Decolonization

  • Nationalist movements were shaped by both Western education and traditional leadership.
  • Cold War rivalries influenced the outcome of decolonization, especially where communism or U.S. intervention played a role.
  • Former colonies struggled with ethnic division, border disputes, and economic dependence, which often stemmed from imperial boundaries and resource exploitation.
  • Not all independence movements succeeded. In places like Quebec, efforts at secession (led by the Quebecois separatist movement) failed, but revealed broader global trends in self-determination.
