🏛️ Key Dates
Centuries are always 1 ahead: 1800s = 19th century
Century Naming Convention
The fastest way to convert years to centuries
The century is always 1 higher than the hundreds digit. 1776 → 18th century. 1914 → 20th century. 2024 → 21st century. The 1st century CE = years 1–100. The 21st = years 2001–2100.
The Renaissance
Renaissance: 14th-17th century. 'Rebirth' of classical learning. Italy first, then Europe.
The Renaissance
The cultural rebirth that bridged medieval and modern Europe
Started in Italian city-states (Florence, Venice) ~1300s. Rediscovery of Greek and Roman classical texts. Key figures: Leonardo da Vinci, Michelangelo, Raphael (art); Machiavelli (politics); Gutenberg's printing press (1440) spread ideas rapidly across Europe.
Protestant Reformation
Reformation: 1517 — Luther's 95 Theses. Split Christianity into Catholic and Protestant.
Protestant Reformation
Martin Luther's challenge that permanently divided Western Christianity

French Revolution
French Revolution: 1789 — Liberty, Equality, Fraternity. Storming the Bastille July 14.
French Revolution
The revolution that reshaped European politics and spread democratic ideals
1789: financial crisis + inequality + Enlightenment ideas → revolution. Key dates: Bastille stormed July 14 1789, Declaration of Rights of Man August 1789, Louis XVI executed 1793, Reign of Terror 1793-94, Napoleon takes power 1799.
Historical Periods
World timelines: Ancient (3000 BC (Before Christ / Before Common Era)-500 AD (Anno Domini / Common Era)) → Medieval (500-1500) → Early Modern (1500-1800) → Modern (1800-present)
Historical Periods
Four broad eras of world history and their approximate dates
Ancient: earliest civilizations through fall of Rome. Medieval (Middle Ages): feudalism, the Church, Black Death. Early Modern: Renaissance, Reformation, Scientific Revolution, Age of Exploration, Enlightenment. Modern: Industrial Revolution, world wars, Cold War, present.
Four key thinkers whose ideas shaped modern government
Locke: natural rights (life, liberty, property), government by consent — influenced US Declaration. Montesquieu: separation of powers into branches — influenced US Constitution. Rousseau: general will, social contract — influenced French Revolution. Voltaire: religious tolerance and free speech.
Locke
Natural rights, consent of the governed
Montesquieu
Separation of powers
Rousseau
General will, social contract
Voltaire
Free speech, religious tolerance
Age of Imperialism
Imperialism peak: 1880s-1914. European powers controlled 80% of the world's land.
Age of Imperialism
The late 19th century scramble for colonies
European powers (Britain, France, Germany, Belgium, Italy) colonized Africa and Asia. Berlin Conference (1884): European nations divided Africa without African input. Britain: 'the sun never sets on the British Empire.' Imperialism's legacy: drew arbitrary borders, exploited resources, created tensions that contributed to WWI.
Cold War Overview
Cold War: 1947-1991. USA vs USSR. NATO (North Atlantic Treaty Organization) (North Atlantic Treaty Organization) vs Warsaw Pact. No direct combat — proxy wars.
Cold War Overview
44 years of ideological conflict between two superpowers
USA (capitalism/democracy) vs USSR (communism). Never fought directly — used proxy wars (Korea, Vietnam, Afghanistan). Key events: Berlin Wall (1961-1989), Cuban Missile Crisis (1962), moon landing (1969). Ended when USSR dissolved December 25, 1991.

🎓 Common Exam Questions
Q: What are the major historical periods and what events define each transition?
A: Ancient History (3000 BC-500 AD): from the first writing in Mesopotamia to the fall of the Western Roman Empire (476 AD). Includes Egypt, Greece, Rome, China's early dynasties. Medieval (500-1500 AD): from Rome's fall to the fall of Constantinople (1453) and the beginning of the Renaissance. Characterized by feudalism, the Catholic Church's dominance, Crusades, Black Death, and the rise of nation-states. Early Modern (1500-1800): Renaissance, Reformation, Age of Exploration, Scientific Revolution, Enlightenment, and Atlantic revolutions (American 1776, French 1789). Modern (1800-present): Industrial Revolution, nationalism, imperialism, world wars, decolonization, Cold War, and globalization. Key: each period's end is often debated — history does not have clean breaks.
Q: Explain the century rule — why is 1776 in the 18th century?
A: Centuries are numbered one AHEAD of the hundreds digit. The 1st century = years 1-100 AD. The 2nd century = 101-200 AD. So the 18th century = 1701-1800 AD. 1776 falls in the 1700s = 18th century. The 20th century = 1901-2000 (not the 1900s as people commonly think — the 21st century began January 1, 2001). Common exam traps: 1492 (Columbus) is in the 15th century. 1066 (Norman Conquest of England) is in the 11th century. 1215 (Magna Carta) is in the 13th century. 1517 (Luther's Reformation) is in the 16th century. Quick rule: take the first two digits and add one — 17 plus 1 = 18th century.
Q: Compare the three great rights documents — Magna Carta (1215), Declaration of Independence (1776), and Declaration of the Rights of Man (1789).
A: Magna Carta (1215, England): King John forced by barons to sign — limited royal power, established that the king must follow the law, created habeas corpus (right not to be imprisoned without trial). First step toward constitutional government. Influenced all later documents. Declaration of Independence (1776, USA): Thomas Jefferson, drawing on Locke — asserted natural rights (life, liberty, pursuit of happiness), government derives power from the consent of the governed, people have the right to abolish government that fails them. French Declaration of the Rights of Man and Citizen (1789): influenced by Jefferson and Enlightenment — liberty, property, security, resistance to oppression. Applied universally to all men (though not women). Together these three documents form the intellectual foundation of modern human rights law and democratic government.
Q: What was the Enlightenment and how did it lead to the American and French Revolutions?
A: The Enlightenment (17th-18th century): a European intellectual movement arguing that reason, not tradition or religious authority, should guide human affairs. Key ideas and thinkers: Locke — natural rights (life, liberty, property), government by consent of the governed, right of revolution. Montesquieu — separation of powers into executive, legislative, and judicial branches to prevent tyranny. Rousseau — the social contract, popular sovereignty. Voltaire — religious tolerance, free speech, criticism of the Church. Impact on American Revolution (1776): Jefferson directly quoted Locke in the Declaration. The Constitution implemented Montesquieu's separation of powers. Impact on French Revolution (1789): Rousseau's popular sovereignty inspired the Declaration of the Rights of Man. The Enlightenment essentially provided the philosophical toolkit for both revolutions.
Q: What was NATO and what was the Cold War division of Europe?
A: NATO (North Atlantic Treaty Organization): formed April 4, 1949 by 12 founding members including the US, UK, France, and Canada — originally to counter Soviet expansion in Europe. Article 5: collective defense — an attack on one member is an attack on all (invoked once, after September 11, 2001). Warsaw Pact (1955): Soviet-led military alliance of Eastern European communist states — the direct counter to NATO. Cold War division: the Iron Curtain (Churchill's phrase) divided Western Europe (democratic, capitalist, NATO) from Eastern Europe (communist, Soviet-controlled). Germany was literally divided — West Germany (NATO) and East Germany (Warsaw Pact), with Berlin split by the Berlin Wall (built 1961, fell 1989). The Cold War ended with Soviet dissolution on December 25, 1991.
