World History Questions for CDS

Renaissance and Reformation (14th-17th Century)

The Renaissance began in Italy around the 14th century and marked a revival of art, science, and humanist thinking after the medieval period. It shifted focus from God-centred to human-centred thought. The Reformation, led by Martin Luther in 1517, challenged the Catholic Church's authority and gave birth to Protestantism.

• Renaissance started in Italian city-states like Florence, Venice, and Genoa.
• Key figures: Leonardo da Vinci, Michelangelo, Galileo (science), Dante, Petrarch (literature).
• Martin Luther nailed 95 Theses on Wittenberg Church door in 1517 — start of Reformation.
• John Calvin extended Reformation to Switzerland and France.
• Counter-Reformation was the Catholic Church's response — Council of Trent (1545-1563).
• Printing press by Gutenberg (1440s) was the technology that spread Reformation ideas fast.

American War of Independence (1775-1783)

Thirteen British colonies in North America revolted against British taxation without representation. The Declaration of Independence was signed on 4 July 1776, written primarily by Thomas Jefferson. The war ended with the Treaty of Paris in 1783, making the United States a sovereign nation.

• Slogan: No taxation without representation.
• Boston Tea Party (1773) was the trigger event — colonists dumped British tea into the harbour.
• Declaration of Independence: 4 July 1776 — Thomas Jefferson the chief author.

• France, Spain, and Netherlands supported the American side against Britain.
• Treaty of Paris (1783) formally ended the war and recognised US independence.

French Revolution (1789-1799)

The French Revolution overthrew the monarchy and established a republic based on ideals of Liberty, Equality, and Fraternity. It was driven by financial crisis, social inequality (Estates system), and Enlightenment ideas. It ended with Napoleon Bonaparte seizing power in 1799 via the coup of 18 Brumaire.

• Three Estates: Clergy (1st), Nobility (2nd), Common people (3rd) — 3rd Estate had 97% of population.
• Storming of the Bastille: 14 July 1789 — symbolic start of the Revolution.
• Declaration of the Rights of Man and Citizen adopted in August 1789.
• Reign of Terror (1793-94) led by Robespierre — mass executions by guillotine.
• Napoleon Bonaparte ended the Revolution by becoming First Consul in 1799.
• The Revolution spread nationalism and republicanism across Europe.

Napoleon Bonaparte and His Era (1799-1815)

Napoleon rose from a Corsican military officer to Emperor of France. He reformed French law through the Napoleonic Code, won major battles, and redrew the map of Europe. His Russian campaign (1812) was his turning point. He was finally defeated at Waterloo (1815) and exiled to Saint Helena.

• Napoleonic Code (1804) — uniform civil law, basis of many modern legal systems.
• Battle of Trafalgar (1805) — Napoleon defeated at sea by British Admiral Nelson.
• Continental System — economic blockade to cripple Britain, ultimately failed.
• Invasion of Russia (1812) — catastrophic failure due to Russian winter and scorched earth policy.
• Battle of Waterloo (1815) — final defeat; exiled to Saint Helena island.
• Congress of Vienna (1815) — European powers redrew borders after Napoleon's defeat.

Russian Revolution (1917)

Russia had two revolutions in 1917. The February Revolution removed Tsar Nicholas II. The October Revolution, led by Lenin and the Bolsheviks, established the world's first communist state. The revolution was inspired by Marxist ideology and fuelled by poverty, WWI losses, and discontent with autocratic rule.

• February Revolution (March 1917 by new calendar) — Tsar Nicholas II abdicated.
• October Revolution (November 1917) — Bolsheviks under Lenin seized power.
• Slogan: Peace, Land, and Bread — addressed soldier, peasant, and worker demands.
• Treaty of Brest-Litovsk (1918) — Russia exited WWI by surrendering territory to Germany.
• Lenin died in 1924; Stalin consolidated power and introduced Five Year Plans.
• USSR (Union of Soviet Socialist Republics) formally established in 1922.

World War I (1914-1918)

WWI began after the assassination of Archduke Franz Ferdinand of Austria-Hungary in Sarajevo on 28 June 1914 by Gavrilo Princip. The war was fought between the Allied Powers (Britain, France, Russia, later USA) and the Central Powers (Germany, Austria-Hungary, Ottoman Empire). It ended with the Treaty of Versailles in 1919.

• Immediate cause: Assassination of Franz Ferdinand; underlying causes — MAIN (Militarism, Alliances, Imperialism, Nationalism).
• Triple Alliance: Germany, Austria-Hungary, Italy. Triple Entente: Britain, France, Russia.
• USA entered war in 1917 after Germany's unrestricted submarine warfare.
• Treaty of Versailles (1919) — Germany blamed (War Guilt Clause), forced to pay reparations.
• League of Nations formed after WWI — proposed by US President Woodrow Wilson.
• Ottoman Empire collapsed; mandates created in Middle East under Britain and France.

World War II (1939-1945)

WWII was the deadliest conflict in human history. It began when Germany invaded Poland on 1 September 1939. The Axis Powers (Germany, Italy, Japan) fought the Allied Powers (Britain, France, USSR, USA). It ended in Europe on 8 May 1945 (VE Day) and in Asia on 15 August 1945 after atomic bombs on Hiroshima and Nagasaki.

• Germany invaded Poland 1 September 1939 — Britain and France declared war on Germany.
• Japan attacked Pearl Harbour (Hawaii) on 7 December 1941 — USA entered the war.
• Operation Barbarossa (1941) — Germany invaded USSR, opening Eastern Front.
• D-Day (6 June 1944) — Allied invasion of Normandy, France — turning point in Western Europe.
• Atomic bombs dropped on Hiroshima (6 Aug) and Nagasaki (9 Aug) 1945.
• United Nations established in 1945 to replace the failed League of Nations.

Cold War (1947-1991)

The Cold War was an ideological and geopolitical rivalry between the USA (capitalism) and USSR (communism) after WWII. There was no direct armed conflict between the two superpowers, but proxy wars were fought worldwide. It ended with the dissolution of the USSR on 25 December 1991.

• Truman Doctrine (1947) — USA promised to support nations threatened by communism.
• Marshall Plan (1948) — USA provided economic aid to rebuild Western Europe.
• NATO formed in 1949 (Western bloc); Warsaw Pact formed in 1955 (Eastern bloc).
• Korean War (1950-53) and Vietnam War (1955-75) were major Cold War proxy conflicts.
• Cuban Missile Crisis (1962) — closest the world came to nuclear war; Kennedy vs Khrushchev.
• Berlin Wall built in 1961, fell in 1989 — symbolic end of Cold War. USSR dissolved in 1991.

• Confusing the February and October Revolutions of Russia — remember February removed the Tsar, October brought the Bolsheviks to power.
• Mixing up Triple Alliance (Germany, Austria-Hungary, Italy — WWI Central Powers) with Triple Entente (Britain, France, Russia — Allied side). Italy later switched sides.
• Thinking the League of Nations was successful — it was not. USA never even joined it. The UN replaced it after WWII.
• Confusing Treaty of Versailles (end of WWI, 1919) with Congress of Vienna (end of Napoleonic Wars, 1815). Both redrew European maps but different eras.
• Getting D-Day date wrong — it is 6 June 1944, Normandy, France. Not to be confused with VE Day (8 May 1945) or VJ Day (15 August 1945).

• MAIN causes of WWI: Militarism, Alliances, Imperialism, Nationalism — easy to recall as MAIN theme of the war.
• For French Revolution sequence: Bastille (1789), Terror (1793), Napoleon (1799) — count in tens: 89, 93, 99.
• Peace, Land, Bread for Russian Revolution — one word for each group: Soldiers (Peace), Peasants (Land), Workers (Bread).
• Cold War blocs: NATO is for the North Atlantic (West/USA side); Warsaw sounds like War-saw — Eastern/USSR side.

• CDS frequently asks about dates and treaties — focus on exact years of key events like Bastille (1789), Versailles (1919), Pearl Harbour (1941), Hiroshima (6 Aug 1945).
• Personality-based questions are common: who led what — Lenin for October Revolution, Robespierre for Reign of Terror, Napoleon for Waterloo, Churchill-Roosevelt-Stalin as Allied leaders in WWII.
• CDS I 2023 and CDS II 2022 both had questions from WWI and WWII causes and outcomes — treat these as near-certain topics every exam.
• Cold War questions often appear as match-the-following: match doctrine/plan with country or year — Truman Doctrine, Marshall Plan, NATO, Warsaw Pact are recurring.
• Do not waste time on very obscure events. Cover the eight key topics in these notes thoroughly — they account for nearly 80-90% of World History questions in CDS GK paper.
