What is Honors World History unit 10?

In 1945, most of Africa and much of South and Southeast Asia were ruled from European capitals. By 1975, nearly all of those colonies were independent states with seats at the United Nations. This unit explains how that happened and what the new nations tried to do with their independence.

Honors World History Unit 10 covers decolonization after World War II and the rise of the Third World. You study Indian independence and the 1947 Partition of India and Pakistan, the Chinese Civil War that ended with a Communist victory in 1949, the Algerian War (1954-1962), the 1956 Suez Crisis, the wave of African independence that peaked in 1960, the Non-Aligned Movement founded in 1961, and the economic and political problems new nations faced. Honors courses vary by school, so your class may add cases like Indonesia or Vietnam, but the core skill stays the same. You compare how colonies became independent and judge how much really changed afterward.

World War II made colonial empires too expensive to hold and too hard to justify.

Britain and France ended the war deeply in debt and could not afford large armies in every colony. The 1941 Atlantic Charter declared that peoples should be able to choose their government, and anti-colonial leaders used that language to support independence, although Britain denied that it required immediate decolonization. Colonial soldiers who fought in the war also returned with stronger demands for political rights. The US and the Soviet Union both criticized old-style European empires, though the US often backed its European allies when it feared communist gains.

How a colony was ruled shaped how it became independent.

Colonies with few European settlers, like Ghana and India, mostly gained independence through negotiation backed by mass protest. Settler colonies, like Algeria and Kenya, usually required armed conflict because settlers refused to give up land and power. Comparing these cases is one of the most common essay tasks in this unit.

Formal independence did not end outside influence.

New nations inherited colonial borders and economies built around exporting raw materials. The US and the Soviet Union competed for their loyalty, sometimes through aid and sometimes through coups and proxy wars. Groups like the Non-Aligned Movement and the Group of 77 were attempts to push back collectively.

Independence came in very different ways, but every new nation faced the same question afterward: how to be truly self-governing in a world shaped by superpowers and old colonial ties.

India, Algeria, Ghana and Egypt each ended European control through a different mix of protest, negotiation and violence. Once independent, they all had to decide whether to join a Cold War bloc and how to build economies that did not just serve their former rulers. When you write about this unit, connect how independence was won to the problems that came after it.

Unit 10 review notes

10.1

Indian independence

India became independent from Britain on August 15, 1947, after about six decades of organized nationalism. The Indian National Congress (INC), founded in 1885, began by asking for reforms within British rule. By the 1920s it was demanding swaraj, or self-rule.

Mohandas (Mahatma) Gandhi turned the movement from an elite organization into a mass one. His method, satyagraha, used nonviolent civil disobedience to make British rule look unjust and unworkable. The non-cooperation movement (1920-1922) boycotted British courts, schools and cloth. Gandhi called it off after protesters killed 22 police officers at Chauri Chaura, because he believed violence would destroy the movement's moral authority.

In 1930 he led the Salt March, walking about 240 miles to the sea at Dandi to make salt in defiance of Britain's salt monopoly. The 1942 Quit India movement demanded immediate British withdrawal and led to the arrest of nearly the entire Congress leadership.

Nonviolence alone did not end British rule. World War II left Britain deeply in debt, the 1946 Royal Indian Navy mutiny raised concerns about unrest in parts of the colonial armed forces, and Clement Attlee's Labour government was committed to transferring power. Jawaharlal Nehru became independent India's first prime minister.

  • Indian National Congress: The Indian National Congress was the main Indian nationalist party, and after its founding in 1885 it shifted from seeking reforms to demanding full independence.
  • Satyagraha: Satyagraha, often translated as "truth force," was Gandhi's philosophy of nonviolent resistance, which aimed to expose injustice by peacefully refusing to obey it.
  • Quit India movement: The Quit India movement was a 1942 Congress campaign demanding that Britain leave India immediately, and it led to mass arrests of nationalist leaders.

Check yourself. Why did Gandhi choose salt as the target of his 1930 campaign? He chose salt because Britain's monopoly and tax affected Indians across class and religious lines. Making salt illegally was also a simple protest that showed how colonial rule reached into daily life.

10.2

The partition of India and Pakistan

Independence in 1947 came with Partition, the division of British India into Hindu-majority India and Muslim-majority Pakistan. Pakistan had two parts about 1,000 miles apart, and East Pakistan became Bangladesh in 1971.

The roots go back decades. The All-India Muslim League formed in 1906, and British separate electorates, which organized voting by religious community, reinforced political divisions between Hindus and Muslims. Under Muhammad Ali Jinnah, the League promoted the Two-Nation Theory, and its 1940 Lahore Resolution called for independent states in Muslim-majority regions, a demand that developed into the campaign for Pakistan. Gandhi and Nehru wanted a united, secular India. Nehru and other Congress leaders accepted Partition in 1947 as communal violence spread, while Gandhi remained opposed in principle but reluctantly acquiesced.

Lord Mountbatten, the last viceroy, moved the handover up to August 15, 1947. Sir Cyril Radcliffe, a British lawyer who had never visited India, had about five weeks to draw borders through Punjab and Bengal, and his line was published two days after independence. Roughly 14 to 15 million people crossed the new borders, and estimates of the dead range from about 200,000 to 2 million.

Kashmir was a princely state with a Muslim-majority population and a Hindu ruler. Pakistan-backed tribal forces invaded in October 1947, after which the ruler signed the Instrument of Accession to India and India sent troops. The conflict became the first India-Pakistan war. Gandhi was assassinated by a Hindu nationalist in January 1948.

  • Two-Nation Theory: The Two-Nation Theory was the Muslim League's argument that Hindus and Muslims were separate nations that needed separate states.
  • Radcliffe Line: The Radcliffe Line was the border between India and Pakistan, which Cyril Radcliffe drew in a few weeks and which was announced two days after independence.
  • Kashmir: Kashmir was a princely state claimed by both India and Pakistan, and its disputed status caused wars in 1947 and later.

Check yourself. Name two reasons the violence of Partition was so severe. The rushed timeline left no adequate plan to protect people crossing the new borders, and the Radcliffe Line was announced only after independence. Millions faced sudden uncertainty as violence was already spreading. Separate electorates and decades of political division along religious lines also contributed.

10.3

The Chinese Civil War

China was never fully colonized, but after the Opium Wars foreign powers controlled treaty ports and held special legal rights there, so historians often call it semi-colonial. The civil war decided who would rebuild China after that century of foreign pressure.

The Nationalists, or Kuomintang (KMT), under Chiang Kai-shek and the Chinese Communist Party (CCP) under Mao Zedong cooperated in the First United Front until April 1927, when Chiang's forces massacred Communists in Shanghai. Surrounded by Nationalist armies, the Communists began the roughly 6,000-mile Long March in 1934. Only about 7,000 to 10,000 of roughly 80,000 to 100,000 original marchers reached northern Shaanxi in 1935. The march strengthened Mao's position within the party, and Yan'an became the Communist headquarters in 1937.

Japan's full-scale invasion of China in 1937 forced the Nationalists and Communists into a Second United Front. The Nationalists took the heaviest losses in large conventional battles, while Communist guerrillas expanded behind Japanese lines and built support among peasants. After Japan surrendered in 1945, the civil war resumed.

The CCP won because land reform earned peasant loyalty, while the KMT lost support through corruption, hyperinflation and falling morale despite US aid. Mao proclaimed the People's Republic of China on October 1, 1949, and Chiang retreated to Taiwan. A communist China pushed the US to resist communism more aggressively across Asia.

  • Kuomintang (KMT): The Kuomintang was China's Nationalist Party, led by Chiang Kai-shek, and it lost the civil war and retreated to Taiwan in 1949.
  • Long March: The Long March was the Communists' roughly 6,000-mile retreat in 1934-1935, which cost most of their army but strengthened Mao Zedong's leadership of the party.
  • Land reform: Land reform was the Communist policy of taking land from landlords and giving it to peasants, and it won the CCP mass rural support.

Check yourself. Why did the Japanese invasion end up helping the Communists? The Nationalists absorbed most of the conventional fighting and losses, while the Communists used guerrilla warfare behind Japanese lines to expand their influence and gain peasant support.

10.4

The Algerian War

Algeria shows why settler colonies were the hardest to decolonize. France invaded in 1830 and later made northern Algeria legally part of France, organized like French departments. About one million European settlers, the pieds-noirs, held the best land and most political power over roughly nine million Muslim Algerians.

Algerian veterans came home from World War II to the same unequal system. When a march at Sétif in May 1945 turned violent, French forces and settler militias killed thousands of Algerians. On November 1, 1954, the National Liberation Front (FLN) launched coordinated attacks across the country, starting the war.

In the Battle of Algiers (1956-1957), French paratroopers broke the FLN's urban network using systematic torture. France won militarily but lost politically, because reports of torture turned opinion in France and abroad against the war. In 1958 the crisis brought down France's Fourth Republic and returned Charles de Gaulle to power.

De Gaulle moved toward negotiation, survived a failed coup by French generals in April 1961, and agreed to the Évian Accords in March 1962. Algeria became independent on July 5, 1962, and most pieds-noirs left for France. Estimates of Algerian deaths range from about 300,000 to the Algerian government's figure of 1.5 million.

  • Pieds-noirs: The pieds-noirs were European settlers in French Algeria, about one million people, who strongly opposed independence.
  • FLN (National Liberation Front): The FLN was the Algerian nationalist organization that launched the war for independence in 1954 and led Algeria afterward.
  • Évian Accords: The Évian Accords were the March 1962 agreement between France and the FLN that ended the war and led to Algerian independence.

Check yourself. France recognized Moroccan and Tunisian independence in 1956, so why did it keep trying to hold Algeria? France treated Algeria as part of France rather than as an ordinary colony, and about one million European settlers lived there and strongly opposed independence.

10.5

The Suez Crisis

The 1956 Suez Crisis showed that Britain and France could no longer sustain a major imperial intervention against strong US opposition. The Suez Canal, opened in 1869, linked the Mediterranean to the Red Sea, and by the 1950s about two-thirds of Western Europe's oil passed through it. Britain became the largest shareholder in the Suez Canal Company in 1875 and occupied Egypt from 1882.

Gamal Abdel Nasser, one of the army officers who overthrew King Farouk in 1952, became the face of Arab nationalism. When the US and Britain withdrew their offer to fund the Aswan High Dam, Nasser nationalized the canal company on July 26, 1956, and said canal revenue would pay for the dam.

Britain, France and Israel secretly planned a response. Israel invaded the Sinai on October 29, and British and French forces then attacked Egypt, claiming they were separating the two sides. British, French and Israeli forces made rapid military gains, but Britain and France failed to regain lasting control of the canal and faced intense financial and diplomatic pressure. Eisenhower, angry at being kept in the dark and worried about pushing Arab states toward Moscow, put heavy financial pressure on Britain, and the Soviet Union threatened intervention.

The UN arranged a ceasefire and created the UN Emergency Force, the first armed UN peacekeeping force, to supervise the withdrawal. British Prime Minister Anthony Eden resigned in January 1957, and Nasser came out as a hero across the Arab world and the decolonizing world.

  • Nationalization: Nationalization happens when a government takes ownership of a private company or industry, as Egypt did with the Suez Canal Company in 1956.
  • Arab nationalism: Arab nationalism was the movement for Arab unity and independence from Western control, and Nasser was its most visible leader in the 1950s.
  • UN Emergency Force: The UN Emergency Force was the first armed UN peacekeeping force. It went to Egypt in 1956 to supervise the ceasefire and the withdrawal of foreign troops.

Check yourself. Britain and France had the military advantage at Suez, so why is the crisis remembered as a defeat for them? US financial pressure, Soviet threats and UN action forced them to withdraw before regaining control of the canal. The crisis showed that they could no longer act as great powers against superpower opposition.

10.6

African decolonization

Most of Africa won independence between 1957 and 1975. Ghana, formerly the Gold Coast, led the way on March 6, 1957, under Kwame Nkrumah, who used strikes, boycotts and mass party organizing to push Britain into negotiating. In 1958 Guinea, led by Sékou Touré, voted to leave France's empire outright. In 1960, often called the Year of Africa, 17 African countries became independent.

Where there were few European settlers, as in Ghana, Nigeria (1960) and most of French West Africa, independence usually came through negotiation. Where settlers held land and power, it took war. In Kenya, Britain put down the Mau Mau uprising (1952-1960) brutally but still granted independence in 1963, with Jomo Kenyatta as leader. Portugal fought in Angola, Mozambique and Guinea-Bissau until a 1974 revolution in Lisbon ended its empire. White-minority Rhodesia held out until it became Zimbabwe in 1980.

New states inherited borders drawn by Europeans during the Scramble for Africa, often cutting across ethnic groups. Congo became independent from Belgium in June 1960 and fell into crisis within weeks. Prime Minister Patrice Lumumba was killed in Katanga in January 1961 by Congolese captors with direct Belgian involvement. The US had supported efforts to remove him, but available evidence does not show that US officials directly organized his killing. Pan-Africanists like Nkrumah helped found the Organization of African Unity in 1963.

  • Pan-Africanism: Pan-Africanism is a movement for unity and cooperation among African nations and people of African descent worldwide.
  • Year of Africa: The Year of Africa is the name given to 1960, when 17 African countries became independent.
  • Mau Mau uprising: The Mau Mau uprising was a 1952-1960 armed rebellion in Kenya over land taken by white settlers, and Britain suppressed it with mass detention and executions.

Check yourself. Why did Ghana's path to independence look so different from Kenya's? Ghana had very few European settlers, so Britain could negotiate a transfer of power. In Kenya, settlers controlled much of the best farmland and resisted African majority rule, contributing to the Mau Mau uprising and a more violent path to independence.

10.7

The Non-Aligned Movement

The Non-Aligned Movement (NAM) was a coalition of mostly new nations that refused to join either the US-led or the Soviet-led bloc. Its roots are in the Bandung Conference of April 1955, where 29 Asian and African countries met in Indonesia. Host Sukarno, India's Nehru, Egypt's Nasser and China's Zhou Enlai attended, and the conference endorsed respect for sovereignty, non-interference in other countries' affairs and peaceful coexistence.

The NAM formally began at the 1961 Belgrade summit with 25 member states. Its best-known founders were Tito of Yugoslavia, Nehru, Nasser, Sukarno and Ghana's Nkrumah. Tito is the surprise on that list. Yugoslavia was a communist country in Europe, but it had split with Stalin in 1948 and refused to take orders from Moscow.

Non-alignment did not mean staying quiet. Members spoke out against colonialism, apartheid in South Africa and nuclear testing, and they used the UN General Assembly to press their case. They also accepted help from both sides; India received Soviet weapons and US food aid.

The movement had real limits. Members disagreed and sometimes fought each other, and India, a founder, lost a border war with China in 1962 and signed a friendship treaty with the Soviet Union in 1971.

  • Non-alignment: Non-alignment was a foreign policy of refusing to join either Cold War military bloc while still taking active positions on world issues.
  • Bandung Conference: The Bandung Conference was the 1955 meeting of 29 Asian and African nations in Indonesia that promoted anti-colonialism and cooperation among new states.
  • Peaceful coexistence: Peaceful coexistence was the Bandung principle that states with different political systems should live side by side without aggression or interference.

Check yourself. How is non-alignment different from neutrality? Neutrality usually means not taking part in a war, while non-alignment meant not formally joining either Cold War power bloc. Non-aligned states could still take public positions on colonialism, apartheid and nuclear testing, and they could accept aid from either side.

10.8

The rise of the Third World

French demographer Alfred Sauvy coined "Third World" in 1952 by analogy with France's Third Estate, the commoners who were ignored before 1789 but then claimed power. He used it for economically underdeveloped countries outside the two dominant Cold War power centers, including many former colonies and long-independent Latin American countries. Later, people often used the term as a broad label for poor countries, so many historians now prefer "Global South," though the terms are not exact synonyms.

Decolonization changed the UN. Membership grew from 51 in 1945 to 127 by 1970, so new nations soon formed a majority in the General Assembly. In 1960 the Assembly passed Resolution 1514, declaring that colonial rule denied basic human rights. In 1964 developing countries formed the Group of 77 to bargain together on trade, and in 1974 they pushed the UN to call for a New International Economic Order.

Independence brought hard problems. Many economies still depended on exporting one or two raw materials, such as cocoa or copper, to former colonizers, a pattern Nkrumah called neocolonialism in a 1965 book. Weak institutions and colonial borders contributed to one-party governments, military coups and internal conflicts. The superpowers turned local conflicts into proxy wars in places like Congo, Vietnam and Angola. In 1973, Arab oil exporters acting through OAPEC imposed an oil embargo while OPEC members raised prices, showing what raw-material producers could gain by cooperating.

  • Third World: The term Third World originally grouped economically underdeveloped countries in Asia, Africa, and Latin America outside the two dominant Cold War power centers. Many, but not all, followed non-alignment.
  • Group of 77: The Group of 77 is a coalition of developing countries that formed at the UN in 1964 to negotiate together on trade and development.
  • Neocolonialism: Neocolonialism is the continued control of former colonies through economic dependence, debt and political interference after formal independence.

Check yourself. What did "Third World" originally mean, and how did its meaning shift? It originally referred to economically underdeveloped countries outside the two dominant Cold War power centers, echoing France's Third Estate. Many were non-aligned, but the categories did not match exactly. Over time, the term became a broad and often dismissive label for poor countries.

TermWho it includedCold War position
First WorldUS, Western Europe, Japan, and alliesCapitalist, mostly in US-led alliances like NATO
Second WorldSoviet Union and Soviet-aligned communist states, especially in Eastern EuropeCommunist bloc led by Moscow; Yugoslavia and later China followed independent paths after splitting with Soviet leadership

Mistakes to avoid in Decolonization and the Third World's Rise

Giving nonviolence all the credit for ending British rule in India

Gandhi's campaigns made British rule morally and practically harder to keep, so it's tempting to stop there. But Britain also left in 1947 because World War II weakened its finances, unrest such as the 1946 Royal Indian Navy mutiny raised concerns about continued colonial rule, and Attlee's Labour government decided to transfer power. Strong answers name the Indian movement and Britain's weakness together.

Thinking Britain and France lost the Suez Crisis on the battlefield

British and French forces quickly captured Port Said and nearby positions at the northern end of the canal, but a ceasefire stopped them before they seized the whole canal. They withdrew because the US used financial pressure against Britain, the Soviets threatened action and the UN demanded a ceasefire. The point of Suez is that financial and diplomatic pressure outweighed the old empires' military advantage.

Treating non-aligned as neutral or as a secret Soviet bloc

Non-aligned countries refused to join either superpower's Cold War military bloc, but they took strong public stands against colonialism and apartheid. Some leaned toward Moscow and others toward Washington, and many took aid from both. Describe the NAM as a group of states protecting their independence in foreign policy, not as a third superpower bloc.

Assuming independence meant economic independence

A new flag and a UN seat did not change an economy built to export cocoa, copper or cotton to Europe. Many new states still depended on former colonizers for trade, loans and expertise, which is what critics like Nkrumah called neocolonialism. When an essay asks how much decolonization changed, weigh political change against economic continuity.
