Decolonization and the Modern World, 1945–2020

How the great European empires came apart, how more than eighty former colonies became independent nations, and how the world grew more closely connected after the Cold War.

In 1945, the United Nations had 51 members, and much of Asia and most of Africa were ruled from London, Paris, Brussels, Lisbon, or The Hague. By 2011, the UN had 193 members. Some countries won independence peacefully, through negotiation. Others won it only after long and bloody wars.

I am Herodotus. I wrote about the Persian Empire, the largest the world had known in my day, and about the Greek cities that refused to be ruled by it. In this unit you will see empires far larger than Persia's come apart within a single lifetime. Why did they fall so quickly after 1945? What did freedom mean for the people of the new nations? And what kind of world has grown up since the Cold War ended?

An original drawing of a new flag flying over a crowdA crowd of people, drawn as simple dark shapes, some with raised arms, watches a flag flying from the top of a tall pole at sunrise. The flag is teal with a white diagonal band and a gold star. Behind them, a large globe is crossed by curving dotted flight paths and small connected dots, like a network. The flag is invented and does not belong to any real country.

This Unit in Brief

Decolonization is the process by which colonies became independent countries. After 1945, the empires of Britain, France, the Netherlands, Belgium, and Portugal broke up. India and Pakistan became independent in 1947, Ghana in 1957, and seventeen African countries in 1960 alone. In South Africa, a white minority government kept a system of racial segregation called apartheid until the early 1990s.

After the Cold War ended in 1991, the world became more connected through trade, travel, and the internet. It also faced new wars, genocides, terrorist attacks, a global financial crisis, climate change, and, in 2020, the COVID-19 pandemic.

Independence in South and Southeast Asia

World War II left the colonial powers weak and in debt, and it showed people in Asia that European armies could be beaten: Japan had occupied French Indochina in 1940 and 1941, then conquered British, Dutch, and American colonies in a few months in 1941 and 1942. The new United Nations Charter spoke of the "self-determination of peoples," and the United States, now the strongest power on Earth, had promised independence to its own colony, the Philippines. The Philippines became independent on July 4, 1946. The largest and most important colony of all was next.

India: Gandhi and nonviolence

Britain had ruled most of South Asia for nearly two centuries. The Indian National Congress, founded in 1885, led the campaign for self-rule. Its best-known leader, Mohandas K. Gandhi, called his method satyagraha, or "truth force": mass, nonviolent refusal to obey unjust laws, with protesters willing to accept arrest and beatings without hitting back. In the Salt March of 1930, Gandhi and his followers walked about 240 miles (390 km) to the sea to make salt in defiance of a British tax, and tens of thousands of Indians were jailed in the protests that followed. In 1942, the Congress launched the Quit India movement, and the British arrested its leaders for most of the rest of the war.

Not all Indians followed Congress. The Muslim League, led by Muhammad Ali Jinnah, feared that Muslims would be a powerless minority in a Hindu-majority India and demanded a separate state, Pakistan. After the war, Britain's new Labour government decided to leave quickly. Violence between Hindus, Muslims, and Sikhs spread in 1946 and 1947, and the last viceroy, Lord Mountbatten, moved the handover forward to August 1947.

Independence and Partition

When
August 14–15, 1947
Where
British India

British India was divided into two countries. Pakistan, in two parts more than 1,000 miles apart, became independent on August 14, and India, with Jawaharlal Nehru as prime minister, at midnight on August 15. The new borders split the provinces of Punjab and Bengal.

The cost of Partition

When
1947–1948
Who
Hindus, Muslims, and Sikhs

About 15 million people crossed the new borders, Hindus and Sikhs fleeing to India and Muslims to Pakistan, in one of the largest migrations in history. In massacres on both sides, somewhere between 200,000 and 2 million people were killed. India and Pakistan also went to war over Kashmir, which both still claim.

Gandhi's death

When
January 30, 1948
Where
New Delhi

Gandhi, who had fasted to stop the killing, was shot by a Hindu nationalist who blamed him for being too generous to Muslims and Pakistan. His ideas about nonviolent resistance later inspired the civil rights movement in the United States and many other campaigns around the world.

Bangladesh

When
1971
Where
East Pakistan

The two halves of Pakistan shared a religion but not a language. After the Pakistani army began a brutal crackdown in East Pakistan, Bengali leaders declared independence on March 26, 1971. After a war in which India intervened, East Pakistan became the independent country of Bangladesh in December 1971.

Southeast Asia

Burma and Ceylon

When
1948
Who
Britain's other Asian colonies

Britain also left Burma (now Myanmar) in January 1948 and Ceylon (now Sri Lanka) in February 1948. Malaya, after a long fight against communist guerrillas, followed on August 31, 1957.

Indonesia

When
1945–1949
Who
Sukarno and Mohammad Hatta

Two days after Japan surrendered, on August 17, 1945, Sukarno and Hatta proclaimed the independence of Indonesia. The Netherlands sent troops to take back its colony, and four years of war and negotiation followed. Under pressure from the United Nations and the United States, the Dutch handed over sovereignty on December 27, 1949.

Indochina

When
1946–1954
Where
Vietnam, Laos, and Cambodia

France fought to keep its colonies in Indochina against Vietnamese communists and nationalists led by Ho Chi Minh. After its defeat at Dien Bien Phu in May 1954, France withdrew. Vietnam was divided, and the war that followed became part of the Cold War (see the Cold War unit).

Israel, the Arab World, and Suez

After World War I, Britain and France had taken control of much of the Middle East under mandates from the League of Nations. Most of these lands became independent states in the 1930s and 1940s, among them Iraq, Lebanon, Syria, and Jordan. The hardest case was Palestine, ruled by Britain. Both Jews and Arabs there saw the land as their homeland. Jewish immigration had grown, especially as Jews fled persecution in Europe, and Arab Palestinians opposed it. Clashes between the two communities, and attacks on the British, grew worse. After the Holocaust, in which six million Jews were murdered, support for a Jewish state grew in many countries.

In 1947, Britain handed the problem to the United Nations. On November 29, 1947, the General Assembly voted for Resolution 181, which recommended dividing Palestine into a Jewish state and an Arab state, with Jerusalem under international control. Jewish leaders accepted the plan. Arab leaders rejected it, arguing that it gave a large share of the land to a minority of its people. Fighting broke out at once.

The State of Israel

When
May 14, 1948
Who
David Ben-Gurion

As the British mandate ended, Jewish leaders declared the independence of Israel. The next day, the armies of Egypt, Transjordan (later Jordan), Syria, Iraq, and Lebanon attacked. By the armistices of 1949, Israel held more land than the UN plan had given it. Jordan held the West Bank and East Jerusalem, and Egypt held the Gaza Strip. No Arab state of Palestine was created.

Refugees

When
1947–1949 and after
Who
Palestinian Arabs and Jews from Arab lands

About 750,000 Palestinian Arabs (UNRWA's figure) fled or were driven from their homes during the war; estimates range from about 700,000 to 900,000. Israel did not let them return, and many of their descendants still live as refugees. In the years after 1948, hundreds of thousands of Jews also left or were forced out of Arab countries, and most settled in Israel.

Wars of 1967 and 1973

When
June 5–10, 1967; October 1973
Where
Egypt, Jordan, Syria, and Israel

In May 1967, Egypt moved large forces into the Sinai, had UN peacekeepers withdrawn, and closed the Straits of Tiran to Israeli shipping, and Jordan signed a defense pact with Egypt; Israel struck first on June 5. In the Six-Day War, Israel took the Sinai Peninsula and Gaza from Egypt, the West Bank and East Jerusalem from Jordan, and the Golan Heights from Syria. UN Security Council Resolution 242 called for Israel to withdraw from territories it had occupied and for every state in the region to be able to live in peace within secure borders. In October 1973, Egypt and Syria attacked Israel on Yom Kippur, the holiest day of the Jewish year.

Steps toward peace

When
1978–1994
Who
Egypt, Israel, Jordan, and the PLO

At Camp David in 1978, with US help, Egypt and Israel agreed to make peace, and they signed a treaty in 1979; Israel returned the Sinai. After a Palestinian uprising, the intifada, began in 1987, Israel and the Palestine Liberation Organization signed the Oslo Accords in 1993, and Jordan made peace with Israel in 1994. A final settlement has never been reached.

The Suez Crisis, 1956

In Egypt, army officers overthrew the British-backed king in 1952, and Gamal Abdel Nasser became the country's leader. Nasser called for Arab unity and independence from the West. On July 26, 1956, he nationalized the Suez Canal Company, which was owned mainly by British and French shareholders. In late October, Israel invaded the Sinai Peninsula, and Britain and France, by secret agreement, attacked Egypt, claiming they were protecting the canal.

The United States, angry that its allies had acted without telling it, and the Soviet Union, which threatened to intervene, both demanded that the invasion stop. Under this pressure, Britain and France accepted a ceasefire in early November. The UN General Assembly created the United Nations Emergency Force, the first armed UN peacekeeping force, to supervise the withdrawal. Suez showed that the old European empires could no longer act on their own against the wishes of the two superpowers.

Independence in Africa

In 1945, only four African countries were fully independent: Egypt (in name, since 1922), Ethiopia, Liberia, and South Africa, which was ruled by its white minority. Everywhere else, Africans lived under British, French, Belgian, Portuguese, or Spanish rule. Many African soldiers had fought for the Allies in World War II, and they came home asking why they should not be free too. Educated nationalists organized political parties, labor unions, and newspapers.

Ghana

When
March 6, 1957
Who
Kwame Nkrumah

The British colony of the Gold Coast became Ghana, usually called the first colony in sub-Saharan Africa to win independence from European rule. (Sudan, which some lists count as sub-Saharan, became independent from joint British and Egyptian rule in January 1956.) Its leader, Kwame Nkrumah, had organized strikes and boycotts and was jailed by the British before winning elections. He dreamed of a united Africa, and Ghana's success encouraged independence movements across the continent.

The Year of Africa

When
1960
Where
West, Central, and East Africa

In 1960 alone, 17 African countries became independent, most of them former French colonies, along with Nigeria, Somalia, and the Belgian Congo. In February 1960, British Prime Minister Harold Macmillan told South Africa's parliament that a "wind of change" was blowing through the continent.

The Congo

When
June 30, 1960
Who
Belgium and Patrice Lumumba

Belgium left the vast Congo with almost no preparation. Within days the army mutinied and the mineral-rich province of Katanga tried to break away. A large UN force was sent in, the new prime minister, Patrice Lumumba, was overthrown and murdered, and the crisis became part of the Cold War (see the Cold War unit).

African unity

When
May 25, 1963
Where
Addis Ababa, Ethiopia

Thirty-two independent African states founded the Organization of African Unity. It agreed to keep the borders drawn by the colonial powers, to avoid endless wars over them, and to support movements still fighting for independence. In 2002 it was replaced by the African Union.

Algeria, 1954–1962

France treated Algeria not as a colony but as part of France itself, home to about a million European settlers. On November 1, 1954, the National Liberation Front (FLN) launched a war for independence. The war was fought with great brutality on both sides: the FLN attacked civilians as well as soldiers, and the French army, which grew to some 500,000 troops, used torture, mass arrests, and forced relocation of villagers. The war divided France and brought down its government in 1958, returning Charles de Gaulle to power. In 1959, de Gaulle accepted that Algerians had a right to decide their own future. The Évian Accords of March 1962 ended the war, and Algeria became independent on July 5, 1962. Most of the European settlers left for France.

Kenya and the Mau Mau

In Kenya, British settlers had taken much of the best farmland in the central highlands. In the early 1950s, a rebellion among the Kikuyu people, known as Mau Mau, attacked settlers and Africans loyal to the colonial government. Britain declared a state of emergency in October 1952 and detained tens of thousands of people (more than 70,000 at the 1954 peak by official count; historians estimate that far more were held over the whole Emergency), and many were abused in the camps. Official figures say more than 11,000 rebels were killed; some scholars think the true number was more than 20,000. Mau Mau fighters killed 32 European civilians and about 1,800 African civilians. Kenya became independent on December 12, 1963, led by Jomo Kenyatta, whom the British had imprisoned. In 2013, the British government said that it "sincerely regrets that these abuses took place" and agreed to pay compensation to 5,228 Kenyans who had been held and mistreated.

The end of the Portuguese empire

Portugal, a dictatorship, refused to give up its African colonies and fought long wars against independence movements in Angola, Mozambique, and Guinea-Bissau from the early 1960s. The wars were so costly that in the Carnation Revolution of April 25, 1974, Portuguese army officers overthrew the dictatorship at home. The new government quickly let the colonies go: Guinea-Bissau in 1974, and Mozambique and Angola in 1975. In Angola, rival movements, backed by the superpowers, Cuba, and South Africa, went on fighting a civil war for decades. In Southern Rhodesia, a white minority government declared independence from Britain in 1965 to avoid majority rule; after a guerrilla war, the country became independent as Zimbabwe in 1980. Namibia, ruled by South Africa, won independence in 1990.

An original map of Africa with approximate borders. Countries independent before 1945 are pale beige. Countries that became independent from 1945 to 1959 are dark teal, from 1960 to 1969 teal, from 1970 to 1979 light teal, and from 1980 to 2011 very light teal. Dependent territories and places whose status is disputed are gray with stripes. Pale beige: Egypt, Ethiopia, Liberia and South Africa. Dark teal, 1945 to 1959: Libya, Sudan, Morocco, Tunisia, Ghana and Guinea. Teal, the 1960s: most of the continent, including Algeria, Mali, Niger, Chad, Nigeria, the Democratic Republic of the Congo, Kenya, Tanzania and Madagascar. Light teal, the 1970s: Guinea-Bissau, Angola, Mozambique and Djibouti. Very light teal: Zimbabwe, Namibia, Eritrea and South Sudan. Western Sahara, on the Atlantic coast south of Morocco, is gray with stripes. São Tomé and Príncipe, the Comoros and the Seychelles, small island countries that became independent in the 1970s, are light teal dots. Cabo Verde (1975, light teal) is shown in a small framed inset in the Atlantic, labeled Cabo Verde 1975. Countries outside Africa, at the edges of the map in Europe and the Middle East, are not shaded and are almost white. Labels inside the countries give the name and year of independence for Algeria (1962), Libya (1951), Egypt (1922), Sudan (1956), Mali (1960) and Niger (1960). Red markers on the coast, each with its label in the sea, point to Ghana (1957), the Democratic Republic of the Congo (1960), Angola (1975), Namibia (1990), South Africa, Mozambique (1975) and Kenya (1963). The Atlantic and Indian Oceans are labeled.
When African countries became independent, 1922–2011. This map is approximate: shading shows the date most often given for each country, and borders are drawn as they are today. Egypt was declared independent in 1922, but Britain kept troops there and great influence until 1956. Eritrea became independent from Ethiopia in 1993, and South Sudan from Sudan in 2011. Western Sahara, which Spain left in 1975, is claimed by Morocco and by an independence movement, and its status is disputed; Morocco's internationally recognized border is drawn at about 27.7°N. Cabo Verde, which lies off the left edge of the map, is shown in a small inset at three times the main scale, and island countries too small to show as shapes, such as the Seychelles, are drawn as dots in their key color. Original map drawn for Jugami from public-domain Natural Earth data.

New Nations and the United Nations

Each new country could join the United Nations, and each had one vote in the General Assembly, the same as the United States or the Soviet Union. As the chart shows, the UN's membership nearly quadrupled between 1945 and 2011. By the end of the 1960s, the countries of Asia and Africa together held more than half the seats in the General Assembly, and they used it to press for an end to colonial rule.

Members of the United Nations, 1945–2011

The Bandung Conference

When
April 1955
Where
Bandung, Indonesia

Leaders from 29 Asian and African governments, including Nehru, Nasser, Sukarno, and China's Zhou Enlai, met to oppose colonialism and to call for cooperation among their peoples. It was the first great meeting of the new nations without the Western powers.

The Non-Aligned Movement

When
September 1961
Where
Belgrade, Yugoslavia

Twenty-five countries founded the Non-Aligned Movement, which promised not to join either the American or the Soviet bloc in the Cold War. Its founders included Nehru, Nasser, Sukarno, Ghana's Nkrumah, and Yugoslavia's Tito. In practice, some members leaned toward one side or the other.

Resolution 1514

When
December 14, 1960
Who
UN General Assembly

The General Assembly adopted the Declaration on the Granting of Independence to Colonial Countries and Peoples by 89 votes to none, with 9 countries, including Britain, France, and the United States, abstaining. It declared that colonial rule denied human rights (see Primary Sources).

An original world map with approximate borders. Countries independent before 1945 are pale beige. Countries that became independent from 1945 to 1959 are dark teal, from 1960 to 1969 teal, from 1970 to 1979 light teal, and from 1980 to 2011 very light teal. Countries that became independent, or independent again, when the Soviet Union, Yugoslavia and Czechoslovakia broke up, from 1991 to 2006, are mauve. Dependent territories and places whose status is disputed are gray with stripes. Dark teal covers much of South and Southeast Asia, among them India, Pakistan, Burma and Indonesia, as well as Israel, Jordan and Syria in the Middle East, Libya, Sudan, Morocco and Tunisia in North Africa, and Ghana and Guinea in West Africa. Most of Africa is teal, for the 1960s. Light teal includes Angola, Mozambique, Bangladesh and Papua New Guinea. Very light teal includes Zimbabwe, Namibia, Eritrea, South Sudan and Timor-Leste. Russia and the other former Soviet republics, from Ukraine and the Baltic states to Kazakhstan, are mauve. Most of the Americas and Europe, with China, Japan, Iran and Australia, are pale beige. Greenland, Taiwan and Western Sahara, on the Atlantic coast of Africa south of Morocco, are gray with stripes. Countries too small to show as shapes, mostly islands, are drawn as small dots in the same colors; among them are Cabo Verde and the Seychelles (light teal), Vanuatu (very light teal) and the Palestinian territories (gray with stripes). French Guiana, on the northeast coast of South America, is still part of France and is pale beige like France. The Pacific, Atlantic and Indian Oceans are labeled.
When the countries of the world became independent, 1945–2011. This map is approximate: shading shows the date most often given for each country, and borders are drawn as they are today. Yemen is shaded for South Yemen (1967); North Yemen was independent from 1918. Malaysia is shaded for Malaya (1957); Sabah and Sarawak joined in 1963. Egypt's independence in 1922 was limited, with British influence until 1956. Estonia, Latvia, and Lithuania, annexed by the Soviet Union in 1940, regained their independence in 1991. Stripes mark dependent territories and places whose status is disputed. French Guiana, on the northeast coast of South America, is still part of France, an overseas region, and is shaded like France. Countries too small to show as shapes, mostly islands, are drawn as dots in their key color. Original map drawn for Jugami from public-domain Natural Earth data.

Apartheid and Its End

South Africa had been self-governing since 1910, but only its white minority, about one person in five, could vote in national elections. In 1948, the National Party won power and began to build apartheid, an Afrikaans word meaning "separateness." Laws classified every South African by race, banned marriage between races, and set aside separate and unequal schools, hospitals, beaches, and neighborhoods. Black South Africans had to carry passes and could be expelled from cities, and millions were forced to move to rural "homelands."

The African National Congress (ANC) led the resistance, at first through strikes, boycotts, and peaceful defiance of the laws. On March 21, 1960, police at Sharpeville opened fire on a crowd protesting the pass laws and killed at least 69 people. The government then banned the ANC. Some of its leaders, including Nelson Mandela, decided that peaceful protest alone could not work and formed an armed wing to sabotage government targets. In 1964, Mandela and other leaders were sentenced to life in prison. On June 16, 1976, police in Soweto fired on schoolchildren protesting against being taught in Afrikaans, and hundreds were killed in the unrest that followed.

Pressure from outside

When
1960s–1980s
Who
The UN, governments, and citizens

The UN condemned apartheid, and many countries banned trade, sports, and cultural ties with South Africa. In 1986, the US Congress passed economic sanctions over President Reagan's veto. Banks and businesses pulled out, and the economy suffered.

Mandela freed

When
February 11, 1990
Who
F. W. de Klerk and Nelson Mandela

President F. W. de Klerk lifted the ban on the ANC and released Mandela after 27 years in prison. The two men negotiated an end to apartheid amid serious violence, and they shared the Nobel Peace Prize in 1993.

Democracy

When
April 27, 1994
Where
South Africa

In South Africa's first election in which all adults could vote, millions waited in long lines to cast a ballot. The ANC won, and on May 10, 1994, Mandela became the country's first Black president. He called for reconciliation between the races.

Truth and Reconciliation

When
From 1996
Who
Archbishop Desmond Tutu, chair

The Truth and Reconciliation Commission heard from thousands of victims of human rights abuses on all sides. People who confessed fully to political crimes could apply for amnesty. Some South Africans felt it brought healing; others felt it let wrongdoers go free.

The World After 1991

When the Soviet Union broke up in 1991, fifteen republics became independent countries: Estonia, Latvia, and Lithuania first, in September, and the other twelve by the time the Soviet Union was dissolved on December 26, 1991. It was the last great wave of new nations (see the Cold War unit). Some people hoped that, with the Cold War over, the world would become more peaceful and more democratic. In parts of Europe and the world it did. In others, the end of old governments led to terrible wars.

The European Union

When
1992–2004
Where
Europe

In the Maastricht Treaty, signed on February 7, 1992, twelve countries created the European Union, which took effect in November 1993. A shared currency, the euro, followed in 1999, and euro notes and coins came into use in twelve countries on January 1, 2002. On May 1, 2004, ten more countries joined, most of them former communist states in Central and Eastern Europe.

The breakup of Yugoslavia

When
1991–1999
Where
Slovenia, Croatia, Bosnia, and Kosovo

Yugoslavia was a federation of six republics and several peoples. When Slovenia and Croatia declared independence in June 1991, war followed. In Bosnia and Herzegovina (1992–1995), about 100,000 people were killed, and armed forces drove people of other ethnic groups from their homes, a practice called ethnic cleansing. NATO bombing and US-led talks ended the war with the Dayton Agreement in December 1995. In 1999, NATO bombed Yugoslavia to stop a Serbian campaign against Albanians in Kosovo. Kosovo declared independence in 2008. Many countries recognize it, but Serbia and many others do not.

Srebrenica

When
July 1995
Where
Bosnia and Herzegovina

Bosnian Serb forces captured Srebrenica, a town the UN had declared a "safe area," and killed more than 8,000 Bosniak (Bosnian Muslim) men and boys. The international war crimes tribunal for the former Yugoslavia ruled that the killings were genocide.

The genocide in Rwanda, 1994

Rwanda, once a Belgian colony, was home to a Hutu majority and a Tutsi minority. Belgian rulers had treated the two groups as separate races and recorded each person's group on identity cards. After independence, Hutu governments discriminated against Tutsi, and a Tutsi-led rebel army, the Rwandan Patriotic Front, invaded in 1990. On April 6, 1994, the plane carrying Rwanda's president was shot down. Within hours, Hutu extremists in the army, the government, and militias began killing Tutsi and moderate Hutu, urged on by radio broadcasts, often using machetes and lists of names. In about 100 days, from April to July 1994, they killed somewhere between 500,000 and more than 1,000,000 people, most of them Tutsi. Between 150,000 and 250,000 women were raped. The killing ended when the Rwandan Patriotic Front won control of the country in July.

The world did little to stop it. The small UN peacekeeping force in Rwanda was cut to about 270 troops after ten Belgian peacekeepers were murdered. The UN later set up the International Criminal Tribunal for Rwanda, which indicted 93 people and became the first international court ever to deliver verdicts for genocide. In Rwanda itself, community courts called gacaca heard more than a million cases.

A Globalized World

Globalization means the growing connection of the world's peoples through trade, money, travel, migration, and communication. It is not new, but after 1991 it sped up. Goods, money, and ideas crossed borders faster than ever before. Globalization lifted hundreds of millions of people out of poverty, but it also cost some workers their jobs, spread financial crises and diseases quickly, and raised hard questions about how to share a crowded planet.

The rise of China

When
From 1978
Who
Deng Xiaoping and his successors

After Mao's death, Deng Xiaoping opened China to foreign trade and investment and allowed private farming and business, while the Communist Party kept full political control. On December 11, 2001, China joined the World Trade Organization as its 143rd member. According to the World Bank, nearly 800 million Chinese people rose out of extreme poverty in the four decades after 1978, about three-quarters of the reduction in the whole world.

Hong Kong

When
July 1, 1997
Who
Britain and China

Britain returned Hong Kong, its colony since the 1840s, to China. Under a 1984 agreement, China promised that Hong Kong would keep its own legal and economic system for 50 years, a policy called "one country, two systems." Portugal returned Macau to China in 1999. Hong Kong and Macau were among the last European colonies in Asia.

The internet

When
1969–2019
Who
Researchers, companies, and billions of users

The internet grew from ARPANET, a US research network begun in 1969. In 1989, Tim Berners-Lee, a British scientist at CERN in Switzerland, invented the World Wide Web, and in 1993 CERN made it free for anyone to use. Smartphones spread after 2007. By 2019, about 4.1 billion people, just over half the world, were online, according to the UN's International Telecommunication Union.

September 11 and the wars that followed

On September 11, 2001, terrorists of the Islamist group al-Qaeda, led by Osama bin Laden, hijacked four airliners. They flew two into the World Trade Center in New York and one into the Pentagon near Washington, D.C., and the fourth crashed in a field in Pennsylvania after passengers fought back. The attacks killed 2,977 people, not counting the hijackers. In October 2001, the United States and its allies invaded Afghanistan, whose Taliban rulers had sheltered al-Qaeda. In March 2003, a US-led coalition invaded Iraq and overthrew Saddam Hussein, saying he had weapons of mass destruction; none were found. Both wars lasted for years and cost many thousands of lives, most of them Afghan and Iraqi. US combat troops left Iraq in 2011, and the last US forces left Afghanistan in 2021.

The financial crisis

When
2007–2009
Where
Worldwide

Banks had made huge bets on risky home loans in the United States. When house prices fell, the bets went bad. On September 15, 2008, the investment bank Lehman Brothers collapsed, and panic spread through the world's banks. Governments spent vast sums to rescue banks, and in 2009 the world economy shrank for the first time since World War II. Millions of people lost jobs and homes.

The Arab Spring

When
From December 2010
Where
North Africa and the Middle East

On December 17, 2010, a Tunisian street vendor set himself on fire to protest his treatment by officials. Protests spread, and Tunisia's president fled on January 14, 2011. In Egypt, mass protests forced President Hosni Mubarak to resign on February 11. Uprisings followed in Libya, Yemen, Bahrain, and Syria. Results varied: Tunisia held democratic elections, while Libya, Yemen, and Syria fell into long civil wars.

Climate change

Burning coal, oil, and gas releases carbon dioxide, which traps heat in the atmosphere. In 1988, the UN helped create the Intergovernmental Panel on Climate Change (IPCC) to assess the science. In 1992, countries signed the UN Framework Convention on Climate Change, and in 1997 the Kyoto Protocol set limits on emissions for wealthy countries. In the Paris Agreement, adopted on December 12, 2015, nearly every country agreed to hold global warming to "well below 2°C" above pre-industrial levels and to try to limit it to 1.5°C. Each country sets its own targets. The IPCC reported that the years 2011–2020 were about 1.1°C warmer than 1850–1900, and NASA found that 2020 tied 2016 as the warmest year in its records.

COVID-19

In late 2019, a new coronavirus was first identified in Wuhan, China. The disease it causes, COVID-19, spread around the world in a few months. The World Health Organization declared a global health emergency on January 30, 2020, and called the outbreak a pandemic on March 11, 2020. Countries closed borders, schools, and businesses. The first vaccines were approved in December 2020, less than a year later. The WHO estimates that about 14.9 million more people died in 2020 and 2021 than would normally have been expected, with a range of 13.3 to 16.6 million. The pandemic showed both how connected the world had become and how much countries depended on each other.

Legacy

In 1945, most of the world's people lived under governments they had not chosen, many of them ruled by distant empires. By 2020, almost every part of the world belonged to an independent state, and the idea that peoples have a right to govern themselves was written into international law. But independence did not end every problem. Many new nations inherited borders drawn by colonial powers, economies built to export raw materials, and few trained officials, and many fell under military rule or one-party government. Some of the conflicts that began in this period, in Kashmir, in Israel and the Palestinian territories, and elsewhere, are still unresolved.

Primary Sources

A primary source was made by people who lived through the events. Read each one closely and ask: Who made this? When? Why? Who was the audience?

"Long years ago we made a tryst with destiny, and now the time comes when we shall redeem our pledge, not wholly or in full measure, but very substantially. At the stroke of the midnight hour, when the world sleeps, India will awake to life and freedom. A moment comes, which comes but rarely in history, when we step out from the old to the new, when an age ends, and when the soul of a nation, long suppressed, finds utterance."

Jawaharlal Nehru, speech to India's Constituent Assembly in New Delhi, on the night of August 14–15, 1947. Text from the Constituent Assembly Debates, Constitution of India. A brief excerpt quoted for teaching.

Why it matters: Nehru gave this speech, known as "Tryst with Destiny," just before midnight, when India became independent. He spoke of freedom, but on the same night Partition was tearing Punjab and Bengal apart, and Gandhi was not in Delhi to celebrate: he was in Calcutta, trying to stop the killing.

Think: What does Nehru mean by a "tryst with destiny" and a "pledge"? Why do you think he says the pledge is redeemed "not wholly or in full measure"?

"All human beings are born free and equal in dignity and rights. They are endowed with reason and conscience and should act towards one another in a spirit of brotherhood."

Universal Declaration of Human Rights, Article 1, adopted by the UN General Assembly in Paris, December 10, 1948, by 48 votes to none, with 8 abstentions. Text from the United Nations. The UN allows the Declaration to be freely reproduced.

Why it matters: The Declaration was written by a committee chaired by Eleanor Roosevelt, with members from many countries. It was not a law, but it set a standard that people under colonial rule, and later the opponents of apartheid, used to argue that their rights were being denied.

Think: In 1948, much of Africa and Asia was still ruled by colonial powers, several of which voted for this Declaration. How could people in the colonies use these words against their rulers?

"1. The subjection of peoples to alien subjugation, domination and exploitation constitutes a denial of fundamental human rights, is contrary to the Charter of the United Nations and is an impediment to the promotion of world peace and co-operation.

2. All peoples have the right to self-determination; by virtue of that right they freely determine their political status and freely pursue their economic, social and cultural development."

Declaration on the Granting of Independence to Colonial Countries and Peoples, UN General Assembly Resolution 1514 (XV), December 14, 1960, Articles 1 and 2. Text from the United Nations Audiovisual Library of International Law. UN document, freely reproducible.

Why it matters: The resolution passed by 89 votes to none, with 9 abstentions, in the year that seventeen African countries became independent. Article 3 added that a lack of "preparedness should never serve as a pretext for delaying independence," rejecting a common argument of the colonial powers.

Think: Why do you think Britain, France, and the United States abstained instead of voting against? What does "self-determination" mean in your own words?

"During my lifetime I have dedicated myself to this struggle of the African people. I have fought against white domination, and I have fought against black domination. I have cherished the ideal of a democratic and free society in which all persons live together in harmony and with equal opportunities. It is an ideal which I hope to live for and to achieve. But if needs be, it is an ideal for which I am prepared to die."

Nelson Mandela, statement from the dock at the Rivonia Trial, Pretoria, April 20, 1964. Text from the Nelson Mandela Foundation. A brief excerpt quoted for teaching; versions of the speech differ slightly in wording.

Why it matters: Mandela and other ANC leaders were on trial for sabotage and could have been sentenced to death. Instead of testifying, he spoke from the dock for more than four hours, explaining why the ANC had turned to armed resistance. He was sentenced to life in prison and released in 1990.

Think: Mandela says he fought against "black domination" as well as "white domination." Why might he have said this in a courtroom in 1964? How did the same idea shape South Africa after 1994?
