Important Dates in World History: A Timeline for Exams
Exam notes on world history dates: Constantinople 1453, the American and French Revolutions, the two World Wars, the United Nations, the space race and 1989.
By GK24 Editorial Team· Published · 4 min read

World history reaches the general studies paper as a list of dates. The examiner rarely asks why a revolution happened; the question is in which year it happened, or which of four events came first. That makes this chapter pure memory work, and the only way to carry it is to hold the dates in chains rather than as loose numbers, so that one date pulls the next out with it. The four chains that matter are the age of discovery, the age of revolutions, the two World Wars, and the Cold War with the space race.
From the ancient world to the age of discovery
The first Olympic Games were held at Olympia in Greece in 776 BCE, the starting point of the Greek calendar. The next date that matters is 1453, when Constantinople fell to the Ottoman Turks under Sultan Mehmed the Second; the Byzantine empire ended, the land route to the east was closed to European traders, and historians often treat the year as the end of the Middle Ages. The search for a sea route followed at once. Christopher Columbus, sailing west for Spain, reached the Americas in 1492, and Vasco da Gama, sailing round Africa for Portugal, reached Calicut on 17 May 1498. The English East India Company received its charter from Queen Elizabeth the First on 31 December 1600. In England the Glorious Revolution of 1688 settled the supremacy of Parliament over the crown without a battle.
The age of revolutions
The American Declaration of Independence was adopted on 4 July 1776, which the United States keeps as its national day. Thirteen years later the French Revolution began with the storming of the Bastille prison in Paris on 14 July 1789, now Bastille Day, and gave the world the slogan of liberty, equality and fraternity. The revolution ended in the rise of a soldier: Napoleon Bonaparte seized power in 1799, crowned himself emperor in 1804, and was finally defeated at the Battle of Waterloo on 18 June 1815 by the allied armies under the Duke of Wellington and Blucher. The Industrial Revolution, which had begun in Britain in the eighteenth century with the steam engine and the textile machines, reshaped Europe through the same years; the Communist Manifesto of Marx and Engels appeared in 1848. The Suez Canal opened in 1869, and the Eiffel Tower was completed in 1889 to mark a hundred years of the French Revolution.
The two World Wars
| Date | Event |
|---|---|
| 28 July 1914 | First World War begins after the assassination at Sarajevo |
| 7 November 1917 | Bolshevik Revolution in Russia under Lenin |
| 11 November 1918 | Armistice ends the fighting of the First World War |
| 28 June 1919 | Treaty of Versailles signed |
| 10 January 1920 | League of Nations comes into being |
| October 1929 | Wall Street Crash begins the Great Depression |
| 1 September 1939 | Germany invades Poland; Second World War begins |
| 7 December 1941 | Japanese attack on Pearl Harbor brings in the United States |
| 6 and 9 August 1945 | Atom bombs Little Boy on Hiroshima and Fat Man on Nagasaki |
| 24 October 1945 | United Nations comes into existence; observed as UN Day |
Two pairs inside this table are the usual traps. The Treaty of Versailles was signed in 1919 but the League of Nations began only in January 1920, and the United Nations Charter was signed at San Francisco on 26 June 1945 but came into force on 24 October, which is why UN Day falls in October and not in June.
The Cold War and the space race
| Year | Event |
|---|---|
| 1949 | NATO founded on 4 April; the Warsaw Pact followed in 1955 |
| 1957 | Sputnik 1, the first artificial satellite, launched by the Soviet Union on 4 October |
| 1961 | Yuri Gagarin becomes the first human in space on 12 April aboard Vostok 1 |
| 1969 | Apollo 11 lands on the Moon on 20 July; Neil Armstrong is the first to walk on it |
| 1989 | The Berlin Wall is pulled down on 9 November |
| 1991 | The Soviet Union is dissolved in December |
| 2001 | Attacks of 11 September in the United States |
Hold the space dates as a rising ladder: satellite in 1957, man in orbit in 1961, man on the Moon in 1969. Hold the end of the Cold War as a falling one: the wall in 1989, the Soviet Union in 1991.
Exam Point of View
Questions here are of three shapes. The first simply gives an event and asks for the year, which is why the whole timeline has to be memorised. The second gives four events and asks which came first or asks them to be arranged in order, so the sequence matters more than the exact day. The third is the near-miss pair, and there are five of these worth drilling: the Treaty of Versailles in 1919 against the League of Nations in 1920; the UN Charter signed in June 1945 against the UN coming into force in October 1945; Gagarin in space in 1961 against Armstrong on the Moon in 1969; the Berlin Wall in 1989 against German reunification in 1990 and the end of the USSR in 1991; and the Depression beginning in 1929 rather than in the worse years that followed.

Practice MCQs on this topic
In which year was the Eiffel Tower built, to celebrate the 100-year anniversary of the French Revolution?
- A.1889
- B.1900
- C.1886
- D.1913
Show answer
Correct answer: A. 1889
Explanation
The correct answer is A, 1889. The Eiffel Tower was completed in Paris in 1889, a hundred years after the storming of the Bastille in 1789, and it served as the entrance arch of the World's Fair held that year to mark the centenary of the French Revolution. Designed by Gustave Eiffel's firm, it was meant to stand for twenty years and remained the tallest structure in the world for about four decades. B is wrong because 1900 was another Paris exposition year but the tower was already eleven years old by then. C is wrong because 1886 is the year the Statue of Liberty, also linked to Gustave Eiffel through its internal framework, was dedicated in New York, which is why the year is offered here. D is wrong because 1913 falls just before the First World War and carries no connection with the tower.
In which battle was Napoleon defeated?
- A.Ligny
- B.Jena
- C.Waterloo
- D.Arcole
Show answer
Correct answer: C. Waterloo
Explanation
The correct answer is C, Waterloo. Napoleon Bonaparte was finally defeated on 18 June 1815 at Waterloo in present-day Belgium by the allied armies led by the Duke of Wellington and the Prussian commander Blucher. The defeat ended the Hundred Days that followed his return from exile on Elba, and he was sent to the remote island of Saint Helena, where he died in 1821; the phrase to meet one's Waterloo comes from this battle. A is wrong because at Ligny, fought two days before Waterloo, Napoleon actually beat the Prussians. B is wrong because Jena in 1806 was one of his greatest victories, in which Prussia was crushed. D is wrong because Arcole in 1796 was an early victory in his Italian campaign that helped make his reputation.
During the French revolution, when did Napoleon ascend to power?
- A.1797
- B.1799
- C.1800
- D.1798
Show answer
Correct answer: B. 1799
Explanation
The correct answer is B, 1799. Napoleon Bonaparte seized power in November 1799 in the coup that overthrew the Directory, and he became First Consul of France, which is the point at which the French Revolution is usually said to have ended; he crowned himself emperor five years later, in 1804. A is wrong because 1797 is the year of the Treaty of Campo Formio, which ended his first Italian campaign but gave him no political office in Paris. C is wrong because by 1800 he was already in power and fought the battle of Marengo as First Consul. D is wrong because in 1798 he was away in Egypt, where his fleet was destroyed by Nelson at the Battle of the Nile, and he returned from that campaign only in 1799. The chain worth keeping is 1789 revolution, 1799 Napoleon in power, 1804 emperor, 1815 Waterloo.
In which year was the Treaty of Versailles signed?
- A.1921
- B.1919
- C.1933
- D.1940
Show answer
Correct answer: B. 1919
Explanation
The correct answer is B, 1919. The Treaty of Versailles was signed on 28 June 1919 in the Hall of Mirrors at the Palace of Versailles and formally ended the First World War between Germany and the Allied powers. It placed the guilt for the war on Germany, imposed heavy reparations, cut its territory and limited its army, and the resentment it created is treated by historians as one cause of the Second World War. A is wrong because 1921 saw separate agreements between the United States and Germany, as the American Senate had refused to ratify Versailles. C is wrong because 1933 is the year Hitler became Chancellor of Germany, a consequence of the post-war settlement rather than part of it. D is wrong because 1940 falls in the middle of the Second World War, twenty-one years after the treaty.
What is 'Little Boy'?
- A.The fission bomb dropped at Hiroshima
- B.The fusion bomb dropped at Nagasaki
- C.The first nuclear bomb tested by America
- D.The first nuclear bomb tested by North Korea
Show answer
Correct answer: A. The fission bomb dropped at Hiroshima
Explanation
The correct answer is A, The fission bomb dropped at Hiroshima. Little Boy was the code name of the uranium fission bomb dropped by the United States on the Japanese city of Hiroshima on 6 August 1945, the first use of a nuclear weapon in war. Three days later, on 9 August, a plutonium bomb named Fat Man was dropped on Nagasaki, and Japan surrendered shortly afterwards. B is wrong because the bomb dropped at Nagasaki was Fat Man, and it was a fission bomb as well, not a fusion or hydrogen bomb, which came only in the 1950s. C is wrong because the first nuclear device tested by the United States was code-named Trinity and was exploded in New Mexico in July 1945. D is wrong because North Korea's first nuclear test came decades later and has no connection with these code names.
In what year did the Great Economic Depression start?
- A.1911
- B.1931
- C.1914
- D.1929
Show answer
Correct answer: D. 1929
Explanation
The correct answer is D, 1929. The Great Depression began with the crash of the New York stock market in October 1929, remembered through Black Thursday and Black Tuesday of that month. Banks failed, industrial output collapsed and unemployment rose across the United States and Europe through the early 1930s; the recovery in America came with Franklin D. Roosevelt's New Deal from 1933. A is wrong because 1911 is associated with the Chinese Revolution, not with any economic collapse. B is wrong because 1931 falls in the depth of the Depression but is two years after it began, and this is the option that catches candidates who remember only that the worst years were in the early thirties. C is wrong because 1914 is the year the First World War started.
The storming of the Bastille, which marks the beginning of the French Revolution, took place on:
- A.4 July 1776
- B.14 July 1789
- C.26 August 1789
- D.18 June 1815
Show answer
Correct answer: B. 14 July 1789
Explanation
The correct answer is B, 14 July 1789. A Paris crowd attacked and captured the Bastille, a royal fortress and prison that stood for the arbitrary power of the Bourbon monarchy, on 14 July 1789, and that day is taken as the start of the French Revolution; France keeps it as its national day, known as Bastille Day. A is wrong because 4 July 1776 is the date of the American Declaration of Independence, which came thirteen years earlier and is the national day of the United States. C is wrong because 26 August 1789 is the date of the Declaration of the Rights of Man and of the Citizen, an important document of the same revolution but six weeks after it began. D is wrong because 18 June 1815 is the Battle of Waterloo, which closed the Napoleonic era twenty-six years later.
The United Nations formally came into existence on:
- A.10 January 1920
- B.26 June 1945
- C.24 October 1945
- D.1 January 1942
Show answer
Correct answer: C. 24 October 1945
Explanation
The correct answer is C, 24 October 1945. The United Nations Charter came into force on 24 October 1945 once it had been ratified by the five permanent members of the Security Council and a majority of the other signatories, and that date is observed every year as United Nations Day. B is wrong, and is the main trap, because 26 June 1945 is the day the Charter was signed at San Francisco; signing and coming into force are four months apart. A is wrong because 10 January 1920 is the date the League of Nations, the predecessor body created after the First World War, came into being. D is wrong because 1 January 1942 is the date of the Declaration by United Nations, a wartime statement by twenty-six Allied countries in which the name was first used, but no organisation existed then.
Who became the first human being to travel into space, and in which year?
- A.Alan Shepard, 1959
- B.Neil Armstrong, 1969
- C.Yuri Gagarin, 1961
- D.Valentina Tereshkova, 1963
Show answer
Correct answer: C. Yuri Gagarin, 1961
Explanation
The correct answer is C, Yuri Gagarin, 1961. The Soviet cosmonaut Yuri Gagarin orbited the Earth once aboard Vostok 1 on 12 April 1961, becoming the first human being in space; the day is observed as the International Day of Human Space Flight. A is wrong because Alan Shepard of the United States made a short sub-orbital flight in May 1961, a few weeks after Gagarin and not in 1959. B is wrong because Neil Armstrong was the first person to walk on the Moon, on 20 July 1969, which is a different first altogether and the one most often confused with this. D is wrong because Valentina Tereshkova, also Soviet, became the first woman in space in 1963, two years after Gagarin. The ladder to remember is Sputnik 1957, Gagarin 1961 and Apollo 11 in 1969.
In which year was the Berlin Wall pulled down?
- A.1989
- B.1990
- C.1991
- D.1987
Show answer
Correct answer: A. 1989
Explanation
The correct answer is A, 1989. The Berlin Wall, built in 1961 to stop movement from East Berlin to West Berlin, was opened and then demolished by crowds on both sides from 9 November 1989, and its fall is the symbol of the collapse of communist rule in eastern Europe. B is wrong because 1990 is the year in which East and West Germany were formally reunified, on 3 October, which follows the fall of the wall but is a separate event. C is wrong because 1991 is the year the Soviet Union itself was dissolved, in December, ending the Cold War; the sequence of wall, reunification and dissolution runs 1989, 1990, 1991. D is wrong because 1987 is the year of the speech in which the American president called for the wall to be torn down, two years before it actually was.
In which year did Apollo 11 land the first human beings on the Moon?
- A.1961
- B.1965
- C.1969
- D.1972
Show answer
Correct answer: C. 1969
Explanation
The correct answer is C, 1969. Apollo 11 landed on the Moon on 20 July 1969, and Neil Armstrong became the first person to set foot on its surface, followed by Buzz Aldrin, while Michael Collins stayed in the command module in orbit. The mission was the culmination of the space race begun by the Soviet Union with Sputnik. A is wrong because 1961 is the year Yuri Gagarin became the first human in space and the year the American president set the goal of reaching the Moon before the decade ended. B is wrong because 1965 belongs to the middle of the programme, when the first spacewalks were made. D is wrong because 1972 is the year of Apollo 17, the last crewed mission to the Moon, so it marks the end of the Moon landings rather than their beginning.
Constantinople fell to the Ottoman Turks in which year?
- A.1453
- B.1492
- C.1498
- D.1517
Show answer
Correct answer: A. 1453
Explanation
The correct answer is A, 1453. Sultan Mehmed the Second captured Constantinople in 1453, ending the Byzantine or Eastern Roman empire, and the city became the Ottoman capital under the name Istanbul. The closing of the overland route to the east pushed European states to look for a sea route to India, and many historians treat 1453 as the end of the Middle Ages. B is wrong because 1492 is the year Christopher Columbus reached the Americas sailing west for Spain, an outcome of the search that the fall of Constantinople set off. C is wrong because 1498 is the year Vasco da Gama reached Calicut by sea, on 17 May. D is wrong because 1517 is the year Martin Luther is said to have published his theses, beginning the Reformation.
Frequently Asked Questions
Why is 1453 an important year in world history?
Constantinople fell to the Ottoman Turks under Sultan Mehmed the Second in 1453. The Byzantine empire ended, the overland trade route to the east was closed to European merchants, and that pushed Spain and Portugal to look for a sea route, leading to the voyages of Columbus in 1492 and Vasco da Gama in 1498.
When did the First and Second World Wars begin and end?
The First World War ran from 28 July 1914 to the armistice of 11 November 1918, and was formally closed by the Treaty of Versailles on 28 June 1919. The Second World War began with the German invasion of Poland on 1 September 1939 and ended in 1945, with Japan surrendering after the atom bombs of August that year.
On which date was the United Nations founded?
The United Nations Charter was signed at San Francisco on 26 June 1945, but the organisation came into existence only on 24 October 1945, when the Charter was ratified by the five permanent members of the Security Council and a majority of the other signatories. That is why 24 October is observed as UN Day.
What were Little Boy and Fat Man?
They were the code names of the two atom bombs used in the Second World War. Little Boy, a uranium fission bomb, was dropped on Hiroshima on 6 August 1945, and Fat Man, a plutonium bomb, on Nagasaki on 9 August 1945. Japan surrendered soon afterwards and the war ended.
What is the correct order of the space firsts?
Sputnik 1, the first artificial satellite, was launched by the Soviet Union on 4 October 1957. Yuri Gagarin became the first human in space on 12 April 1961 aboard Vostok 1. Neil Armstrong became the first person to walk on the Moon on 20 July 1969, during the Apollo 11 mission.
In what order did the Cold War end?
The Berlin Wall was opened and pulled down from 9 November 1989, East and West Germany were reunified on 3 October 1990, and the Soviet Union was formally dissolved in December 1991. Keeping the sequence 1989, 1990 and 1991 in mind settles most questions on this period.
