Revolutions, world wars and myths worth debunking: the events that shaped the world, told with the right dates and the sources at the bottom of the page.
- Martin Luther and the Protestant Reformation: A Summary Martin Luther was a German Augustinian monk who, according to tradition, nailed 95 theses against the sale of indulgences to the door of the Castle Church in Wittenberg in 1517. The act opened a religious process that lasted decades, later known as the Protestant Reformation, which led to Luther's excommunication and to a new Christian doctrine that took hold mainly in Germany and in the Scandinavian and Baltic countries. The clash with Emperor Charles V only ended in 1555 with the Peace of Augsburg, which split the territory of the Empire between Catholics and Lutherans.
- Capetian Dynasty: Who Were the Kings Who Built Medieval France The Capetian dynasty ruled France from 987 to 1328, starting when an assembly of nobles elected Hugh Capet king. At first his real power covered a tiny territory, roughly 1,000 square kilometers between Paris and Orléans: the rest of the kingdom belonged to powerful feudal lords. Over the next two centuries the Capetian kings grew the Crown's holdings through alliances, marriages and war, culminating in Philip II Augustus's victory at Bouvines in 1214. Louis IX brought the dynasty to its religious and institutional peak, while Philip IV the Fair clashed openly with the papacy. When the direct line died out in 1328, the throne passed to the Valois, a branch of the same family.
- Italian City-State: What It Was, How It Began, and How It Changed The Italian city-state was the form of self-government with which, starting in the late 11th century, many cities in northern and central Italy ran their own affairs, pulling free of direct control by bishops and feudal lords. It began as a government of consuls elected by an assembly of heads of household, then shifted to a foreign official called the podestà, and from the mid-13th century saw the institutions of the popolo take shape alongside it, organized by guild and led by the captain of the people. Through the 13th and 14th centuries, conflict between leading families and the popolo wore this balance down and opened the way to city lordships, the signorie. Venice followed a different path from the start, with an elected doge and its own system of councils.
- Manorialism: what it is and how the early medieval manor worked Manorialism was how large landed estates were organised in Carolingian Europe between the 8th and 9th centuries. The manor (or curtis) split into two parts: the demesne, farmed directly for the lord, and tenant land worked by peasant families in exchange for dues. Labour obligations, known as corvée, tied the two halves together. Historians now trace this model back to the Roman-era great estates. It is an economic system, distinct from feudalism, which is a political relationship between a lord and a vassal.
- American Revolution: Timeline and Summary, 1765-1783 The American Revolution was the process, between 1765 and 1783, through which Britain's Thirteen Colonies in North America broke away from Great Britain and became the United States. It began as a dispute over taxes and political representation, escalated through a decade of protests and harsher laws, and turned into an eight-year war. The Declaration of Independence, adopted on July 4, 1776, marked the political break, but full recognition of independence came gradually from other nations, ending only with the Treaty of Paris in 1783. What emerged was not yet a federal union: the Constitution followed several years later.
- Middle Ages: a summary of a thousand years of feudalism and crusades The Middle Ages is the period historians conventionally place between 476, when the Western Roman Empire fell, and 1492, when Columbus reached the Americas: roughly ten centuries, split by another symbolic line, the year 1000, into the Early and Late Middle Ages. Feudalism and vassalage take shape during this span, a ruler like Charlemagne is crowned by the Church, eight major Crusades cross the Mediterranean toward the Holy Land, and the Black Death, between 1347 and 1352, kills millions across Europe. The opening and closing dates are not the only option: other historians, such as Christoph Cellarius in 1688, have argued for a different span. This Recap follows the main waypoints, from the fall of Rome to the edge of the modern era.
- The Renaissance: What It Was, When It Began, and Why It Changed Europe The Renaissance is the period of European history in which, starting from Florence and the other Italian city-states, scholars rediscovered the texts and ideals of ancient Greece and Rome and developed new approaches to art, science and politics. It begins around the middle of the fourteenth century and runs through the fifteenth and sixteenth, with exact boundaries still debated among historians. It grew out of the work of chancellors, philosophers and artists in Italian courts and republics, then spread across Europe helped along by the printing press. Its most lasting legacy is the method of observation and verification that would feed into the scientific revolution.
- Eton College: The History of the UK's Most Famous School Eton College was founded in 1440 by King Henry VI, who wanted to give free board, lodging and schooling to a group of poor boys, the King's Scholars. Within a few years the foundation changed shape, began taking in fee-paying pupils too, and started a long transformation that, through reforms of its curriculum and admissions, turned it into one of the most prestigious and expensive schools in the United Kingdom. Its fame still rests largely on the prime ministers and public figures who studied there.
- Ancient Greece: What Is a Polis and How Athenian Democracy Began Ancient Greece was never a single state, but hundreds of independent city-states, the poleis, each with its own laws and its own form of government. In Athens, through two separate rounds of reform, Solon and later Cleisthenes opened the way to democracy, a government in which citizens decided the laws themselves by meeting in assembly. That same world of rival cities also produced philosophy, theatre, a large share of Western literature and the Olympic Games. It is a legacy still taught in schools, not least because so many of its words (polis, democracy, theatre) have reached us intact.
- The Atomic Bomb: How Nuclear Fission Works, and the History of Hiroshima and Nagasaki The atomic bomb is a weapon that releases an enormous amount of energy by splitting the nuclei of heavy atoms such as uranium or plutonium, a process called nuclear fission. The Manhattan Project, the secret program that built the first American atomic bombs, cost $2.2 billion at the time and employed 130,000 people at its peak. On 6 August 1945 the United States dropped Little Boy on Hiroshima, and three days later, on 9 August, Fat Man on Nagasaki: the only two atomic bombs ever used in a war. Deaths ran into the tens of thousands in the months that followed, and Japan surrendered on 14 August 1945, a decision whose relative weight of causes historians still debate. Since 1970 the Treaty on the Non-Proliferation of Nuclear Weapons has tried to limit the spread of these weapons around the world.
- The Roman Empire: rise, peak and fall The Roman Empire begins in 27 BC, when Octavian takes the name Augustus and becomes the first emperor. Over the following two centuries the Pax Romana holds together a territory that by around AD 100 contains, on the highest estimates, up to 100 million people, across land that today belongs to some fifty countries. The high point is Trajan's reign, which in AD 117 pushes the borders from northern Britain to the Caspian Sea. Then come the long third-century crisis, the administrative split, and in 476 the deposition of the last western emperor. The eastern half, however, does not fall at all: it keeps calling itself the Roman Empire until 1453.
- Apollo 11: How the 1969 Moon Landing Happened On 20 July 1969 the lunar module Eagle from Apollo 11 touches down in the Sea of Tranquility, and a few hours later Neil Armstrong becomes the first person to walk on the Moon, followed by Buzz Aldrin, while Michael Collins stays in orbit aboard the command module Columbia. It comes after years of a space race with the Soviet Union, opened by the 1957 launch of Sputnik and given a fresh target by President John F. Kennedy in 1961, and after the rehearsals flown under Project Mercury and Project Gemini. The Apollo program is not without accidents — a crew dies on the ground in 1967, another nearly fails to return in 1970 — but it puts twelve astronauts on the Moon in all, across six successful missions between 1969 and 1972.
- Halloween History: From Samhain to Trick-or-Treating Halloween falls on the night of October 31 and, according to the most widely accepted reconstruction, traces back to the ancient Celtic festival of Samhain, which marked the new year and the start of winter. Over the centuries the festival became entangled with the Christian calendar, when the Church fixed All Saints' Day on November 1 and the night before took the name "All Hallows' Eve," the source of "Halloween." Symbols like the carved pumpkin and customs like trick-or-treating grew out of older practices, the hollowed-out turnips of Ireland and the medieval door-to-door customs of souling and guising, carried to America by nineteenth-century Irish and Scottish emigrants. From there Halloween also became a multibillion-dollar commercial event, with record U.S. spending in 2025.
- The World Map: How It Was Made and Who Decides Its Borders The world map is the result of centuries of adjustments, not a drawing fixed once and for all. Its oldest known origin is a Babylonian clay tablet dated between 700 and 500 BCE, while the shape sailors still use was born in 1569, with Gerardus Mercator's projection. Political borders change through a precise mechanism, the UN admits new states as members on the Security Council's recommendation, but genuine recognition remains an act each country carries out on its own. Official geographical names, instead, go through the work of UNGEGN, the United Nations group of experts dedicated to place names. Two concrete examples, Nauru's name change to Naoero notified to the UN on June 26, 2026, and South Sudan's admission as the 193rd member state in 2011, show how the map keeps changing.
- History of Christmas: Origins and Traditions Around the World Christmas began as a Christian holiday, but it inherited rituals and symbols from much older pagan celebrations, including Roman Saturnalia and Nordic Yule. December 25 has no basis in the Gospels: it was chosen centuries later, most likely to overlap with existing winter-solstice festivals. Over the centuries the holiday swung between extremes, from rowdy medieval carnival to an outright ban in Puritan America, before being reshaped in the 1800s into the quiet family celebration familiar today. Around the world it's still celebrated on different days and in very different ways: Orthodox Christians mark it on January 7 because of a calendar gap, while countries such as Italy and Japan have built their own traditions, from the Befana to Christmas Eve fried chicken.
- Why September Isn't the Seventh Month: The Origin of Month Names Nearly all twelve month names come from the calendar of ancient Rome, a mix of gods, emperors and plain numbers. The earliest Roman year had only ten months and began in March, not January. Over time two more months were added, then Julius Caesar reformed the calendar to run 365 days a year, and two months, July and August, were renamed to honor him and the emperor Augustus. September, October, November and December still carry a number in their name that no longer matches their real position in the year.
- 9/11: What Happened on September 11, 2001, and What Changed After On September 11, 2001, nineteen men tied to the Islamist group al-Qaeda hijacked four passenger jets in the United States. Two planes hit the Twin Towers of the World Trade Center in New York, which collapsed within an hour and 42 minutes of the first impact; a third struck the Pentagon, just outside Washington; the fourth crashed in a Pennsylvania field after passengers tried to retake the cockpit. In total, 2,977 people died, most of them in New York. Within hours the United States closed its entire national airspace for the first time in its history, and over the following months and years the country changed its laws, its security apparatus and its foreign policy, from the war in Afghanistan to the PATRIOT Act.
- History of Pizza: From Naples to UNESCO Heritage The word "pizza" already appears in a document from 997 written in Gaeta, but the dish as we know it today was born in nineteenth-century Naples, sold cheap as street food and in humble pizzerias. The most famous story, that Queen Margherita gave her name to the pizza with the three colors of the Italian flag in 1889, is actually a popular but historically disputed legend: very similar pizzas were already around decades earlier. In 2017 UNESCO recognized the art of the Neapolitan pizzaiuolo as intangible cultural heritage of humanity. From there pizza spread across the world, spawning thousands of local variants and a few very Neapolitan social customs along the way.
- The History of Football Rules: From 1863 to VAR Football as we know it began in London in 1863, when twelve clubs founded the Football Association and wrote down the first shared set of rules. From there the game changed piece by piece: goalkeepers were formalized, the crossbar arrived, offside was relaxed step by step, and the penalty kick grew out of two disputed incidents in Scotland and England. Cards and VAR are even more recent inventions, created to solve problems that had shown up on the pitch. IFAB, the body that has decided the rules since 1886, brings together the British football associations and FIFA.
- Table Tennis Rules: How Ping Pong Works, from the Table to Scoring Table tennis, known worldwide as ping pong, started out as a parlour game in Victorian England in the 1880s, when the upper class played it after dinner with whatever was lying around. The name "Ping-Pong" arrived in 1901, when the games company Jaques of London trademarked it, inspired by the sound the ball made against paddle and table. The official rules, set out by the International Table Tennis Federation in its 2025 statutes, define the table's size, the net's height, the ball's specifications and the scoring system, where a game is won at 11 points. The sport only made it to the Olympics in 1988, in Seoul, decades after becoming a Paralympic event in 1960. Along the way, the ball itself changed twice, first in size and then in material, for reasons of both play and safety.
- Why Korea Is Divided: North Korea's History and How It's Ruled North and South Korea have been separate states since 1948, the outcome of several factors layered on top of each other, the legacy of Japanese occupation, the division the Allies drew along the 38th parallel in August 1945, and the Korean War of 1950-53, which ended only in an armistice never followed by a peace treaty. In the north, the Democratic People's Republic of Korea has been led since 1948 by the Kim dynasty, by Kim Jong Un since 2011, through a single ruling party and a state ideology of self-reliance called Juche. North Korea publishes no reliable official statistics and its economy depends almost entirely on trade with China; since 2006 the country has been under a series of UN Security Council sanctions tied to its nuclear and missile programs. Technically, the two Koreas remain in a suspended conflict more than seventy years on.
- Italian Unification (Risorgimento): Summary, Dates and Key Events Italian unification, known in Italian as the Risorgimento, is the process that turned a peninsula split among several states into a single kingdom between the late eighteenth century and 1861. It began with the failed risings of the Carbonari and with Mazzini's republican campaigning, and gathered speed once Cavour's Piedmont carried the Italian question to the table of the great powers. Three wars were fought against Austria, in 1848, 1859 and 1866, and in 1860 Garibaldi's Expedition of the Thousand toppled the Kingdom of the Two Sicilies. A short law of 17 March 1861 proclaimed the Kingdom of Italy, but Venetia and Rome only joined in 1866 and 1870.
- The Mussolini Myth: How Fascist Propaganda Built the Duce The "myth of Mussolini" was the public persona built to order by Fascist propaganda: an infallible, tireless, ever-young Duce single-handedly lifting Italy back on its feet. The regime built it through systematic press censorship, control of radio and cinema, and a purpose-built ministry, the Minculpop, that told newspapers what to print and what to leave out. Some legends born in those years, like the claim that trains always ran on time, were later dismantled by historians. The myth peaked with the proclamation of the Empire in 1936 and collapsed quickly between 1943 and 1945, when military defeat swept away the leader's image along with the regime.
- Ancient Egypt Summary: Pharaohs, Pyramids and Gods Ancient Egyptian civilization grew up along the Nile and lasted for thousands of years, from prehistory to the Islamic conquest of the 7th century AD. Its founding moment is the unification of Upper and Lower Egypt under a king called Menes, identified by many scholars with Narmer, around 3150 BC. From there came a system ruled by the pharaoh, seen as a living god and guarantor of the world's balance (ma'at), an original writing system, hieroglyphics, and monuments such as the pyramids of Giza that remain among the most famous works in human history. It was not a static civilization: it went through periods of great strength and periods of crisis before merging into Ptolemaic Egypt and, later, the Roman province.
- The History of Carbonara: True Origins and False Myths Carbonara passes for one of the oldest dishes in the Roman tradition, but it is a twentieth-century dish: classic Roman cookbooks never mention it, and as late as 1949 Ada Boni's famous collection does not record it. The oldest known written trace of the name dates from 23 August 1939, in a Dutch-language newspaper of the Dutch East Indies that mentions a trattoria in Trastevere. The most famous hypothesis has the dish born in September 1944 from the meeting between an Italian cook and Allied army rations, but it remains a hypothesis, and historians still argue about it. The first written recipes, from the 1950s, were very different from today's: the first Italian version, from 1954, called for pancetta, gruyère and garlic. The modern canon — guanciale, pecorino, egg and pepper — only settled in the 1990s.
- The Cold War: What It Was, Why It Started and How It Ended The Cold War was the confrontation between the United States and the Soviet Union that ran from the end of the Second World War to 1991. It is called "cold" because the two superpowers never fought each other directly: both had nuclear weapons, and an open clash would have been too destructive for either side to survive intact. Instead they competed through rival military alliances, economic aid used as political leverage, espionage, propaganda and wars fought elsewhere — in Korea and in Vietnam. Europe was split along a line Churchill called an "iron curtain" in 1946, and Berlin became the sharpest point of contact. The confrontation ended between 1989, when the Berlin Wall came down, and 25 December 1991, when Gorbachev resigned and the Soviet Union ceased to exist.
- French Revolution Summary: Causes, Phases and Consequences The French Revolution is the sequence of events that between 1789 and 1799 swept away absolute monarchy in France and rewrote the rules of political life. It grew out of a public finance crisis and a society divided by birth into three estates, in which the nobility was exempt from the main taxes. Within months the Third Estate turned itself into a National Assembly, the Bastille fell and the Declaration of the Rights of Man and of the Citizen was adopted. Then came the Republic, the king's execution, the Terror and finally the coup that brought Napoleon Bonaparte to power.
- Industrial Revolution: What Changed and Why The Industrial Revolution is the shift from an economy of fields, workshops and muscle power to one of machines, factories and coal. It begins in Britain in the last decades of the eighteenth century and runs its course through the first thirty years of the nineteenth, starting with spinning and reaching almost every sector. It is not one invention but a chain of them: spinning machines, the steam engine made economical by James Watt, coal, iron, the railway. The result is an unprecedented rise in wealth alongside cities that grow within a few decades and working conditions that are brutal. A second wave, between the 1860s and the early 1900s, brings electricity and the internal combustion engine and shifts the centre of industry towards Germany and the United States.
- World War 1: Causes, Fronts and Consequences World War 1 was the conflict that between 1914 and 1918 drew in the major European powers and their empires, mobilising roughly 65 million men. The trigger was the assassination of Archduke Franz Ferdinand in Sarajevo on 28 June 1914; in a little over five weeks, a system of opposing alliances turned a quarrel between Austria-Hungary and Serbia into a continental war. The German plan for a quick victory stalled on the Marne, and the western front settled for years into a line of trenches running from Belgium to Switzerland. The balance shifted in 1917: the United States came in, Russia pulled out. It ended with the armistice of 11 November 1918 and with peace treaties that redrew the map of Europe while leaving plenty of questions unanswered.
- World War 2: Causes, Turning Points and Consequences World War 2 was the conflict that between 1939 and 1945 set the Allies — Britain, France, the United States and the Soviet Union — against the Axis powers of Germany, Italy and Japan. It opened on 1 September 1939 with the German invasion of Poland, but its roots lie in the previous two decades: the terms imposed on Germany after World War 1, the economic collapse of the early 1930s, the Nazi seizure of power and a run of territorial expansions the other powers accepted without resisting. In 1941 the war became truly global, with the German attack on the Soviet Union and the Japanese attack on Pearl Harbor. It ended with the German surrender in May 1945 and the Japanese surrender signed on 2 September 1945. Estimates of the dead run past 50 million, most of them civilians.
