Unit 8.5 — Decolonization after 1900（1900–Present）

Essential Question:
How did people pursue independence after 1900?

One-glance Review

• India and Pakistan → Won independence from Britain in 1947 after mass protest, negotiation, and partition(分治)

• Ghana → Became the first sub-Saharan African country to gain independence in the 20th century

• Algeria → Won independence from France through violent struggle and guerrilla warfare(游击战)

• Vietnam → Nationalist and communist movements combined in an anti-colonial war, then Cold War conflict

• Egypt → Asserted sovereignty(主权) through the Suez Crisis

• Nigeria → Gained independence, but ethnic and regional tensions led to civil war

• Quebec → Pursued autonomy through political reform and nationalist activism rather than full-scale decolonization war

Core Ideas

Nationalism, Independence, and Postcolonial Conflict

• After 1900, colonial peoples increasingly demanded:

  • Self-determination(民族自决)

  • National sovereignty(国家主权)

  • Political independence

  • Control over land and resources

• Independence movements used different methods:

  • Political negotiation

  • Mass protest

  • Civil disobedience (公民不服从)

  • Armed struggle

  • Guerrilla warfare (游击战)

• Even after independence, many new states faced:

  • ethnic conflict (族群冲突)

  • one-party rule (一党制)

  • military coups (军事政变)

  • Cold War intervention

The end of empire often brought freedom, but not always stability.

1. The Global Context of Decolonization

Why Decolonization Accelerated

• In the 20th century, nationalist groups challenged colonial rule through:

  • land reform

  • political negotiation

  • armed struggle

• Failures of earlier independence movements after World War I increased anticolonial sentiment(反殖民情绪)

• After World War II:

  • empires became less politically acceptable

  • European powers were weakened

  • wartime ideas of freedom spread more widely

  • the rise of the United Nations supported self-rule claims

Key Concept

• Decolonization after 1900 was shaped not only by nationalism, but also by the Cold War and the postwar international order.

2. Movements for Autonomy: India and Pakistan

Nationalist Background

• The drive for Indian self-rule began in the 19th century with the Indian National Congress

• In 1920, its major leader was Mohandas Gandhi

• Hindu and Muslim groups initially cooperated in opposing British rule

• The Muslim League, founded in 1906, argued for a separate Muslim state

Gandhi and Mass Protest

• Gandhi promoted:

  • nonviolence(非暴力)

  • noncooperation(不合作)

  • civil disobedience

• Not all Indian leaders agreed with Gandhi’s methods or his emphasis on Hindu-Muslim unity

• Still, many groups temporarily set aside differences until after World War II

Independence and Partition

• After World War II:

  • Britain was weakened

  • Indian political and military pressure increased

  • Britain failed to fulfill promises of greater rights

• The Royal Indian Navy Revolt (1946) helped convince Britain that it could no longer rule India

• In 1947, both India and Pakistan gained independence

Division and Conflict

• Many Muslims feared being a minority in a Hindu-majority India

• This distrust had deep historical roots

• The result was partition(分治):

  • India became a mainly Hindu-majority state

  • Pakistan became a separate Muslim state

Independence in South Asia came through negotiation, but it was accompanied by division and communal tension(宗教社群紧张).

3. Decolonization in Ghana and Algeria

Ghana: Negotiated Independence

Road to Independence

• Britain negotiated independence with its West African colony of the Gold Coast

• The Gold Coast joined with former British Togoland to form Ghana

• Ghana became the first sub-Saharan African country to gain independence in the 20th century

• UN-led negotiations helped Ghana gain independence in 1957

• Kwame Nkrumah became its first president in 1960

Nkrumah and Nation-Building

• Kwame Nkrumah was influenced by nationalism he encountered in the United States and Britain

• He promoted a national identity through:

  • a heroic past

  • founding fathers

  • a flag

  • an anthem

  • museums

  • monuments

• He also supported public works and development projects such as hydroelectric plants(水力发电站)

Limits of Independence

• Critics accused Kwame Nkrumah of:

  • running the country into debt(债务)

  • tolerating corruption(腐败)

• In 1964, he claimed dictatorial powers under a One-Party State

Pan-Africanism

• Kwame Nkrumah strongly supported Pan-Africanism(泛非主义)

• In the 20th century, Pan-Africanism often meant:

  • unity of African peoples

  • shared culture and ideas

  • rejection of former colonial interference

• He founded the Organization Of African Unity in 1963

Algeria: Violent Independence

Why Algeria Was Different

• Algeria was a French colony, but France treated it as part of France itself

• Large numbers of French settlers lived there

• Because of this, France strongly resisted Algerian independence

Algerian War For Independence

• The war began in 1954

• The main independence movement was led by the FLN (National Liberation Front)

• The FLN used guerrilla techniques (游击战术) against French forces

• The conflict became extremely violent:

  • hundreds of thousands of Algerians died

  • torture(酷刑) by the French military was widespread

Charles de Gaulle and Independence

• The Algerian conflict divided France politically

• In 1958, Charles de Gaulle gained expanded presidential power under the Fifth Republic

• He bypassed the French National Assembly and used a referendum(公民投票) to gain support for Algerian independence

• Algeria became independent in 1962

After Independence

• Independence did not bring immediate peace

• Thousands of pro-French Algerians and settlers fled

• Violence continued inside Algeria

• The FLN established a socialist authoritarian government(社会主义威权政府) and maintained a One-Party State

Algerian Civil War

• In 1991, violence broke out again after an election crisis

• The Islamic Salvation Front won the first round of elections, but the election was canceled

• This triggered the Algerian Civil War (1991–2002)

• In 2011, the long military state of emergency was finally lifted

Algeria shows that decolonization could require violent revolution and still lead to long-term political instability.

4. Negotiated Independence in French West Africa

French Decolonization

• France also negotiated independence with its colonies in French West Africa

• These included:

  • Senegal

  • Ivory Coast

  • Niger

  • Upper Volta

• France had ruled these territories since the late 1800s using indirect rule(间接统治)

Why Independence Came

• France had invested in the region through:

  • railroads

  • agricultural development

  • trade

• By the mid-1950s, African political parties had grown stronger, including:

  • democratic groups

  • socialist groups

  • communist groups

• By 1959, many French West African colonies had negotiated independence

In parts of Africa, decolonization happened through diplomacy rather than full-scale war.

5. Nationalism and Division in Vietnam

Anti-Colonial Struggle

• France had long ruled Indochina

• After World War II, France reoccupied southern Vietnam

• A bloody war for independence followed

• Ho Chi Minh, the communist leader of North Vietnam, appealed to nationalism to unify the country under one government

Division of Vietnam

• The Vietnamese war of independence lasted until 1954

• The peace settlement divided the country into:

  • North Vietnam

  • South Vietnam

• Elections were planned for 1956 to reunify the country

• Those elections never happened because:

  • many in South Vietnam opposed communism

  • the United States feared Ho Chi Minh would win

Cold War Conflict

• War then broke out between North and South Vietnam

• The United States supported South Vietnam militarily

• Pro-communist forces in the South were known as the Viet Cong

• The Viet Cong fought a guerrilla war against U.S. troops

Outcome

• U.S. casualties and opposition to the war increased

• President Nixon began withdrawing troops in 1971

• The last U.S. troops left in 1975

• North Vietnam then took control of South Vietnam

• The war caused:

  • between one and two million deaths

  • major destruction

  • instability in Southeast Asia

Later Developments

• From the 1980s, Vietnam introduced some market-based reforms(市场化改革)

• Later, Vietnam and the United States restored trade and diplomatic relations

Vietnam’s independence struggle became deeply entangled with the Cold War.

6. Struggles and Compromise in Egypt

Egypt’s Changing Status

• Egypt became a nominally independent kingdom in 1922

• However, Britain retained important treaty rights

• A 1936 Anglo-Egyptian treaty gave Egypt more autonomy

• Britain still kept troops in Egypt to protect the Suez Canal

Gamal Abdel Nasser

• After World War II, Egypt became one of the founding members of the Arab League

• In 1952, Gamal Abdel Nasser and Muhammad Naguib overthrew the king

• This established the Republic of Egypt

• Gamal Abdel Nasser became a major supporter of Pan-Arabism(泛阿拉伯主义)

Domestic Reforms

• Gamal Abdel Nasser blended:

  • Islam

  • socialism(社会主义)

• He introduced:

  • land reform

  • socialist cooperatives(社会主义合作社)

  • nationalization(国有化) of some industries and banks

Suez Crisis

Causes

• The Suez Canal symbolized colonial exploitation in Egyptian eyes

• Britain and France had long controlled major interests in the canal

• In 1956, Gamal Abdel Nasser nationalized the canal

Crisis and Resolution (危机与解决)

• Israel invaded Egypt with encouragement from Britain and France

• Britain and France then occupied the canal zone, claiming to enforce a UN cease-fire

• However:

  • the United States opposed their intervention (反对他们的干预)

  • the Soviet Union also opposed it

  • the United Nations helped broker a settlement

Results

• Foreign troops withdrew

• The canal became an international waterway under Egyptian sovereignty (主权)

• UN peacekeepers were sent to Sinai

• The crisis showed that:

  • old European empires were weaker

  • Egypt could resist colonial influence

  • non-alignment(不结盟) mattered in the Cold War

7. Independence and Civil War in Nigeria

Independence

• Nigeria gained independence from Britain in 1960

• It was the most populous state in Africa

Biafran Civil War

Causes

• The war began in 1967

• The Igbo people in the oil-rich southeast tried to secede(分离出去) and form Biafra

• They sought autonomy because of attacks from the northern Hausa-Fulani Muslim group

Outcome

• The secession failed

• Biafra ceased to exist in 1970

• Nigeria granted amnesty(大赦) to many Igbo military leaders

• Civilian rule still did not return immediately

Political Challenges

• Nigeria experienced a series of military coups

• Democratic civilian rule was restored only in 1999 under Olusegun Obasanjo

• The government created a federation of 36 states to reduce ethnic and religious tribalism(部族主义)

Continuing Problems

• Friction remained among:

  • Yoruba groups

  • Igbo groups

  • Islamic groups in the north

• Some states adopted shariah(伊斯兰教法) alongside secular law

• In the Niger River Delta:

  • people accused the government of exploiting oil resources

  • oil companies were blamed for pollution

  • militants attacked oil wells and pipelines

Nigeria shows that independence did not automatically resolve ethnic, religious, or regional divisions.

8. Canada and the “Quiet Revolution” in Quebec

Quiet Revolution

Background

• Quebec was deeply rooted in French culture and Catholicism

• English rule over former New France created a long political and cultural divide

• Many Quebecois identified more strongly with French than British traditions

Change in the 1960s

• The Quiet Revolution involved major political and social reforms in Quebec

• The Liberal Party gained power and reformed economic policies

• French Canadian nationalism grew stronger

Radicalization and Limits

• Some splinter groups used extremist tactics, including terrorist bombings

• Canadian Prime Minister Pierre Trudeau, himself from Quebec, preserved Canadian unity

• In 1995, a referendum (公投) for Quebec independence failed narrowly (以微弱差距未通过)

Quebec represents a nationalist autonomy movement that relied more on reform and referendum than anti-colonial war.
