Samacheer Class 10 Social Science - The World After World War II

Three main causes of the Chinese Revolution of 1911 were as follows. First, the decline and corruption of the Qing (Manchu) dynasty, which had grown weak and inefficient and was unable to govern or modernise the country effectively. Second, increasing foreign domination: China had been humiliated by unequal treaties, loss of territory and foreign 'spheres of influence' granted to Western powers and Japan, which angered patriotic Chinese. Third, the spread of new nationalist and republican ideas, especially those of Dr. Sun Yat-sen and his revolutionary party, who called for the overthrow of the monarchy and the founding of a republic. Together these forces brought down the Qing dynasty and created the Republic of China.

The Long March of 1934-35 was a famous strategic retreat by the Chinese Communist Party during its civil war with the Kuomintang. Surrounded and under attack by Chiang Kai-shek's Nationalist forces in their base in Jiangxi, about a hundred thousand Communists broke out and marched roughly nine thousand kilometres across mountains, rivers and harsh terrain to the safer northern region of Yan'an. The journey took about a year, and only a small fraction of those who set out survived. Despite the enormous losses, the Long March saved the Communist movement from destruction and established Mao Zedong as the undisputed leader of the party. It also became a powerful symbol of Communist endurance.

Mao Zedong (Mao Tse-tung) played the central role in making China a communist country. He reorganised the Chinese Communist Party around the peasantry rather than the urban workers, recognising that China's vast rural population could form the basis of revolution. He developed successful guerrilla-warfare tactics, led the party through the Long March, and built strong support in the countryside through land reform. After helping resist the Japanese occupation and then defeating Chiang Kai-shek's Nationalists in the civil war, Mao proclaimed the People's Republic of China on 1 October 1949. As leader, he introduced sweeping communist policies, nationalising industry and collectivising agriculture, which transformed China into a communist state.

Strictly speaking, the Council of Europe did not itself transform into the European Union; they are separate organisations. The Council of Europe, founded in 1949, is a wider body that promotes human rights, democracy and the rule of law across Europe. European economic and political integration, however, developed along a parallel path. It began with the European Coal and Steel Community in 1951, expanded into the European Economic Community (EEC) created by the Treaty of Rome in 1957, and grew through later agreements. Finally, the Maastricht Treaty of 1992 established the European Union, bringing together economic union, common policies and eventually a single currency, the euro, uniting many European nations.

Organise a structured classroom debate with two teams (USA supporters vs Soviet supporters), assign roles, prepare opening statements, rebuttals and closing remarks, and conclude with teacher-led reflection.

To highlight the profound human suffering caused by wars, a class album can be collaboratively prepared using pictures and information related to the Korean War, the Arab-Israeli conflicts, and the Vietnam War. This album should include compelling historical photographs that depict the devastation, displacement, and loss of life experienced by civilian populations and combatants alike. Alongside the images, brief descriptions, eyewitness accounts, and casualty figures should be incorporated to provide context and emphasize the tragic consequences of these conflicts. The final section of the album should offer reflections on the humanitarian impact, encouraging students to consider the broader implications of war and the importance of peace.

The Baghdad Pact was a defensive military alliance formed in 1955 during the Cold War. Its original members were Iraq, Turkey, Iran, Pakistan and the United Kingdom, with the United States giving strong support without formally joining. The aim of the pact was to contain the spread of Soviet communist influence into the Middle East and South-West Asia by creating a 'northern tier' of friendly states along the Soviet border. After Iraq withdrew following its revolution of 1958, the alliance was renamed the Central Treaty Organisation (CENTO). The pact achieved only limited military success and eventually faded, but it clearly reflected the Cold War rivalry between the superpowers in the region.

The Marshall Plan, officially called the European Recovery Program, was a major American aid programme launched in 1948 and named after the US Secretary of State George Marshall. Under it, the United States gave around thirteen billion dollars in economic assistance to help rebuild the war-shattered economies of Western European countries after the Second World War. The aim was both humanitarian and political: to restore prosperity, revive trade, and prevent the spread of communism by reducing the poverty and instability on which it might thrive. The plan greatly speeded Europe's recovery, but the Soviet Union rejected it for itself and its satellite states, which further deepened the divide of the Cold War.

During the Cold War the world was often divided into three 'worlds'. The 'First World' meant the capitalist, industrialised nations led by the United States; the 'Second World' meant the communist bloc led by the Soviet Union; and the 'Third World' referred to the countries that did not belong firmly to either camp. These were mostly the newly independent, developing nations of Asia, Africa and Latin America, many of which had recently emerged from colonial rule. Third World countries were generally poorer and less industrialised, and a large number of them chose a policy of non-alignment, refusing to take sides in the Cold War while concentrating on their own economic development.

The Cuban Missile Crisis of October 1962 was defused through tense negotiation rather than war. After American spy planes discovered Soviet nuclear missiles being installed in Cuba, President John F. Kennedy ordered a naval 'quarantine', or blockade, of the island and demanded their removal. For thirteen days the world stood on the brink of nuclear war. The crisis was finally resolved when the Soviet leader Nikita Khrushchev agreed to remove the missiles from Cuba in return for a public American promise not to invade Cuba, together with a secret agreement that the United States would later withdraw its own missiles from Turkey. This peaceful settlement avoided a catastrophic war between the two superpowers.
