1st Millennium BC Timeline: Events, People and History

Events in the 1st Millennium BC 56

14000 BC – 300 BC Jomon period World's earliest pottery — hunter-gatherers of the islands The Jomon period is named for the cord-marked (jomon) pottery its people produced — among the oldest pottery in the world. These were sophisticated hunter-gatherers, fishers and foragers who lived a largely sedentary life in the Japanese archipelago for over ten thousand years, long before agriculture arrived.
1500 BC – 500 BC Vedic period — the Vedas composed Sanskrit hymns and the roots of Hinduism Following the Indus decline, the Vedic period saw the composition of the Vedas — the oldest scriptures of Hinduism — in archaic Sanskrit. This era shaped Indian religion, the caste system, and the philosophical traditions later expressed in the Upanishads.
1200 BC – 550 BC Zoroaster and the rise of Zoroastrianism One of the world's earliest monotheistic faiths The prophet Zoroaster (Zarathustra) taught a dualist vision of a single supreme god, Ahura Mazda, locked in cosmic struggle with evil. Zoroastrianism became the dominant religion of the Persian empires for over a thousand years and influenced ideas of heaven, hell and judgement in later faiths.
753 BC – 716 BC Romulus — first King of Rome Romulus, legendary founder and first king of Rome, rules for 37 years according to tradition. He establishes the Senate (100 patrician elders), divides the people into tribes, and creates the basic military structure. His reign includes the Rape of the Sabine Women — the abduction of women from neighbouring tribes to populate the new city — and wars with the Sabines, Latins and Etruscans. He disappears in a thunderstorm in 716 BC, deified as the god Quirinus.
753 BC – 476 The Roman Civilisation The Roman civilisation — kingdom, republic and empire — shaped Western law, language, architecture, religion and governance more profoundly than any other ancient civilisation. From the legendary founding of Rome by Romulus in 753 BC to the deposition of the last western emperor Romulus Augustulus in 476 AD, Rome endured for over twelve centuries, governing at its peak an empire of 70 million people stretching from Scotland to Mesopotamia.
753 BC Founding of Rome According to Roman tradition, Romulus founds the city of Rome on the Palatine Hill on 21 April 753 BC, after killing his twin brother Remus in a dispute over the city's location and its sacred boundary. The story — wolves, augury, fratricide — is almost certainly mythological, but archaeology confirms continuous settlement on the hills above the Tiber from around this period. Rome begins as one of many Latin villages in central Italy.
715 BC – 672 BC Numa Pompilius — second King Numa Pompilius, a Sabine chosen by the Senate, transforms Rome from a warrior settlement into a functioning state. He establishes the Roman religious calendar, the Vestal Virgins, the College of Pontiffs, and the flamines (priests). Credited with 43 years of peace — an extraordinary reign. The Roman religious institutions he creates will survive, with modifications, for over a millennium.
678 BC – 550 BC Median Empire The Medes unify the Iranian peoples The Medes were the first to unify the Iranian tribes into a single state, overthrowing Assyrian dominance and forging an empire across the plateau. Their kingdom was absorbed by Cyrus the Great when he founded the Achaemenid empire, but it laid the groundwork for a unified Iran.
660 BC Emperor Jimmu founds the empire (legendary) The mythical first emperor, descendant of the sun goddess By tradition, Jimmu — a descendant of the sun goddess Amaterasu — founded the Japanese imperial line in 660 BC, making it the world's longest continuous hereditary monarchy. Jimmu is a legendary figure recorded in the 8th-century chronicles Kojiki and Nihon Shoki rather than a historically verified ruler, but the date remains foundational to Japanese national identity.
616 BC – 578 BC Tarquinius Priscus — Etruscan influence begins Lucius Tarquinius Priscus, the fifth king of Rome, is the first of the Etruscan dynasty. Under him Rome begins its transformation from a village into a city: the Forum is drained, the Circus Maximus laid out, the Capitoline temple begun. Etruscan engineering, art and religious practice flood into Rome. The triumphal procession, the fasces, the toga — all are Etruscan borrowings that become permanently Roman.
578 BC – 534 BC Servius Tullius — the great reformer Servius Tullius, sixth king, transforms Roman society through the census — a systematic count of citizens classified by wealth into voting classes. The Servian constitution creates the comitia centuriata (assembly of centuries), tying military obligation to political rights. He also expands Rome's boundaries with the Servian Wall and creates the four urban tribes. His reforms lay the constitutional foundations that will persist through the Republic.
551 BC – 479 BC Confucius 551–479 BC — founder of Confucianism Kong Qiu (Confucius) was born in the state of Lu in 551 BC. His teachings on social harmony, filial piety, ritual propriety and benevolent government became the foundation of Chinese civilisation for 2,500 years. His conversations were recorded by disciples in the Analects. Confucianism shaped Chinese government, education, family structure and ethics more profoundly than any other single thinker.
550 BC – 330 BC Achaemenid Empire — First Persian Empire The largest empire the ancient world had yet seen Founded by Cyrus the Great in 550 BC, the Achaemenid Empire stretched from the Balkans and Egypt to the Indus Valley — the largest empire the world had yet seen. It was renowned for its tolerance of subject peoples, its network of royal roads and the administrative system of satrapies.
534 BC – 509 BC Tarquinius Superbus — the last king Lucius Tarquinius Superbus (Tarquin the Proud), seventh and final king of Rome, rules by terror. He murders his father-in-law Servius Tullius, abolishes the Senate's power, and rules as a tyrant in the Greek mould. His son Sextus rapes the noblewoman Lucretia, who kills herself after naming her assailants. Her kinsman Lucius Junius Brutus leads the aristocratic revolt that expels the Tarquins in 509 BC, ending the monarchy forever.
522 BC – 486 BC Darius the Great Empire at its zenith; Persepolis built Darius I brought the Achaemenid Empire to its greatest extent and organised it into provinces governed by satraps, with a common coinage, road network and postal system. He began the great ceremonial capital at Persepolis. His invasions of Greece, however, met defeat at Marathon in 490 BC.
509 BC Foundation of the Roman Republic The expulsion of Tarquinius Superbus in 509 BC establishes the Roman Republic. Power is divided between two annually elected consuls — neither can accumulate the tyrannical power of a king. The Senate, composed of former magistrates, guides foreign policy and controls the treasury. The system of checks and balances — collegiality, annual terms, the veto — becomes the constitutional model Rome will follow for nearly five centuries.
494 BC First Secession of the Plebs The plebeian class — the non-patrician majority — withdraws to the Sacred Mount outside Rome, refusing to serve in the army until their grievances are addressed. The patricians, unable to defend Rome without them, negotiate: the tribunes of the plebs are created, magistrates with the power to veto any action harmful to a plebeian citizen (the sacrosanct "intercessio"). The first great victory of Roman democracy — won by walking away.
451 BC – 450 BC The Twelve Tables Rome's first written law code — the Twelve Tables — is inscribed on bronze and displayed in the Forum around 451–450 BC, following plebeian demands for laws that could not be arbitrarily interpreted by patrician magistrates. The Tables cover debt, property, family law, inheritance and procedure. Though the original bronze was destroyed in the Gallic sack of 390 BC, reconstructed fragments survive. Roman jurists will call them the "source of all law."
390 BC The Gallic Sack of Rome A Gallic tribe — the Senones under their chieftain Brennus — defeats the Roman army at the Battle of the Allia and sacks Rome in 390 BC (or 387 BC by some chronologies). The city is burned; only the Capitol holds out. According to legend, the sacred geese of Juno wake the defenders when a night assault is attempted. Rome pays a ransom in gold; when the Romans complain the weights are rigged, Brennus throws his sword on the scales: "Vae victis" — Woe to the conquered.
343 BC – 290 BC The Samnite Wars Three wars against the Samnites — a powerful Italic people of the Apennine mountains — between 343 and 290 BC cement Roman dominance of peninsular Italy. The Second Samnite War (326–304 BC) includes the humiliation of the Caudine Forks (321 BC), where an entire Roman army is forced to pass under the yoke. Rome recovers, learns, adapts — and ultimately prevails. By 290 BC, Rome controls most of Italy south of the Po valley.
322 BC – 185 BC Maurya Empire First empire to unify the subcontinent The Maurya Empire, founded by Chandragupta Maurya in 322 BC, was the first state to unify most of the Indian subcontinent under one centralised administration. From its capital Pataliputra it became one of the largest empires of the ancient world.
312 BC – 63 BC Seleucid Empire Greek successor state rules Persia After Alexander's death his general Seleucus seized the eastern territories, founding the Seleucid Empire that ruled Persia for some two and a half centuries. It spread Hellenistic culture across the region before fragmenting and giving way to the resurgent Parthians.
300 BC – 1279 Chola dynasty (South India) A great maritime and temple-building power The Cholas of the Tamil south were one of the longest-ruling dynasties in history, rising from the Sangam age to a medieval maritime empire that projected naval power across the Bay of Bengal to Southeast Asia. They built magnificent temples such as the Brihadeeswarar at Thanjavur and patronised bronze sculpture and Tamil literature.
300 BC Euclid — Elements of Geometry The foundation of mathematics for 2,000 years Around 300 BC, Euclid of Alexandria wrote the Elements, a thirteen-volume treatise that systematised all known geometry into a rigorous axiomatic framework. Starting from just five postulates, he derived hundreds of theorems. The Elements became the most widely used mathematics textbook in history, used in schools until the 20th century, and established the model of deductive proof that underlies all mathematics.
300 BC – 300 Yayoi period Rice farming, bronze and iron arrive from the mainland The Yayoi period brought wet-rice cultivation, bronze and iron metallurgy, and the potter's wheel to Japan from Korea and China. These innovations drove population growth and the emergence of stratified society and local chieftaincies — the foundations of the Japanese state.
287 BC – 212 BC Archimedes of Syracuse The greatest mathematician and engineer of antiquity Archimedes (c.287–212 BC) was a Greek mathematician, physicist, engineer, astronomer and inventor born in Syracuse, Sicily. Son of the astronomer Phidias, he was possibly related to King Hiero II of Syracuse. He is ranked alongside Newton and Gauss as one of the three greatest mathematicians of all time. He left nine surviving treatises covering geometry, hydrostatics, statics and mathematical physics, and invented war machines that held Rome at bay for two years. He died when Roman soldiers breached Syracuse in 212 BC — allegedly while working on a geometry problem.
287 BC – 212 BC Archimedes — buoyancy, lever and pi The greatest scientist of antiquity Archimedes of Syracuse (c.287–212 BC) discovered the principle of buoyancy — that a body submerged in fluid experiences an upward force equal to the weight of fluid it displaces — reputedly while stepping into his bath. He proved the law of the lever, calculated pi as lying between 3 10/71 and 3 1/7, determined the surface area and volume of a sphere, and laid the foundations of hydrostatics and statics. He also invented the Archimedes screw for raising water and designed war machines to defend Syracuse against the Romans.
264 BC – 241 BC First Punic War Rome's first conflict with Carthage — the great maritime empire of North Africa — begins over Sicily in 264 BC. Rome, a land power with no naval tradition, builds a fleet from scratch, reportedly copying a captured Carthaginian warship. The Romans add the "corvus" — a boarding bridge — to turn sea battles into land fights. After 23 years and enormous losses on both sides, Rome wins Sicily (241 BC), its first overseas province.
247 BC – 224 Parthian Empire Persian revival; rival of Rome The Parthian (Arsacid) Empire restored native Iranian rule and became Rome's great rival in the east for nearly five centuries, its famed horse-archers and cataphracts repeatedly checking Roman expansion — most notably annihilating Crassus's legions at Carrhae in 53 BC.
246 BC – 208 BC Construction of the Great Wall begins Linking earlier walls into a unified northern defence Qin Shi Huang ordered the linking and extension of existing northern walls into a continuous defensive barrier against Xiongnu nomads. Hundreds of thousands of workers — soldiers, peasants and convicts — built the wall under brutal conditions. This early wall was largely of earth and wood; the iconic stone wall seen today was built by the Ming dynasty. The wall represents the most ambitious construction project of the ancient world.
245 BC Eureka! — Archimedes discovers buoyancy On Floating Bodies: a submerged body displaces its weight in fluid King Hiero II suspected a goldsmith had mixed silver into a supposedly pure gold crown. He tasked Archimedes to test it without destroying it. The solution came to Archimedes while stepping into a public bath — he noticed the water level rose as he entered, and realised that a body displaces a volume of fluid equal to its own volume. Since gold is denser than silver, a silver-adulterated crown would displace more water than a pure gold crown of the same weight. Legend says he leapt from the bath and ran naked through the streets shouting "Eureka!" (I have found it!). He formalised the principle in his treatise On Floating Bodies, the first systematic work in hydrostatics.
240 BC Eratosthenes measures the Earth First accurate calculation of Earth's circumference Around 240 BC, Eratosthenes of Cyrene, chief librarian at Alexandria, calculated the circumference of the Earth by measuring the difference in the angle of the sun's shadow between Alexandria and Syene (modern Aswan) at noon on the summer solstice. His result of approximately 252,000 stadia is remarkably close to the modern value of 40,075 km — an error of less than 2%. It was the first scientific measurement of the size of a planet.
221 BC – 206 BC Qin Dynasty — First unified China Qin Shi Huang unifies the warring states In 221 BC, Ying Zheng of the state of Qin conquered the last of the warring states and proclaimed himself Qin Shi Huang — First Emperor of China. He standardised weights, measures, currency, axle widths and writing across the empire, creating the template for Chinese civilisation. His dynasty lasted only 15 years but its legacy shaped China for two millennia. The name "China" derives from "Qin".
221 BC – 210 BC Qin Shi Huang — First Emperor of China 221–210 BC — unifier, tyrant, visionary Ying Zheng became king of Qin at age 13 and conquered all rival states by 221 BC, aged 38. As First Emperor he standardised writing, currency, weights and measures across China, built the first Great Wall, and connected the empire with roads and canals. He also burned books and buried scholars alive to suppress dissent. He spent his final years obsessively seeking immortality. His terracotta army of 8,000 warriors was discovered in 1974.
218 BC – 201 BC Second Punic War — Hannibal invades Italy Hannibal Barca crosses the Alps with 37 war elephants and an army of 26,000 men in 218 BC, fighting his way to the gates of Rome. He destroys Roman armies at the Trebia (218 BC), Lake Trasimene (217 BC) and Cannae (216 BC) — the latter killing perhaps 70,000 Romans in a single afternoon, the most lethal single day in Roman history. Yet Rome refuses to negotiate, raises new armies, and shifts strategy. Scipio Africanus carries the war to Africa; at the Battle of Zama (202 BC) Hannibal is defeated.
212 BC Archimedes killed by a Roman soldier Syracuse falls — "Do not disturb my circles" In 212 BC, after a two-year siege, Roman forces breached the walls of Syracuse. Archimedes was working on a geometry problem when a Roman soldier approached and ordered him to come before the general Marcellus. Archimedes refused, saying "Do not disturb my circles." The soldier killed him on the spot. Marcellus was reportedly devastated — he had given orders that Archimedes was not to be harmed, and had admired him greatly. Marcellus arranged for an honourable burial and saw to the welfare of his family. Archimedes was approximately 75 years old.
210 BC Terracotta Army buried with Qin Shi Huang 8,000 warriors guard the emperor in death Qin Shi Huang was buried in a vast mausoleum near Xi'an, guarded by an army of 8,000 life-size terracotta soldiers, horses and chariots — each with individual facial features. The tomb complex also reportedly contained rivers of mercury representing the empire's waterways. The terracotta warriors were accidentally discovered by farmers digging a well in 1974 and are now considered one of the greatest archaeological discoveries in history.
202 BC – 220 Han Dynasty The golden age that defined what it means to be Chinese The Han dynasty ruled for over 400 years and is considered China's first golden age. It consolidated Confucianism as state ideology, expanded the empire into Central Asia, and opened the Silk Road. Paper was invented during the Han period. The ethnic majority of China still call themselves "Han people" after this dynasty. It fell to internal rebellion and warlordism — giving rise to the Three Kingdoms period immortalised in Chinese literature.
149 BC – 146 BC Third Punic War — Destruction of Carthage The Third Punic War ends with the total destruction of Carthage in 146 BC. The city is besieged for three years; when it falls, the surviving 50,000 inhabitants are sold into slavery and the city is burned for 17 days. The site is later salted — or so the legend goes (the salting is almost certainly apocryphal). The phrase "Carthago delenda est" (Carthage must be destroyed), attributed to Cato the Elder who appended it to every Senate speech, defines Rome's ruthlessness when threatened.
146 BC Destruction of Corinth — Rome masters Greece In the same year as Carthage's destruction, Rome sacks Corinth — the greatest city of mainland Greece — after the Achaean League resists Roman authority. The male population is killed, the women and children enslaved. Greece becomes the Roman province of Achaea. Rome has now absorbed the entire Hellenistic world; Greek culture floods back into Rome in the form of philosophy, art, architecture and literature. "Graecia capta ferum victorem cepit" — captive Greece captured her savage conqueror (Horace).
133 BC – 121 BC The Gracchi — land reform and political murder Tiberius Gracchus (tribune 133 BC) proposes redistributing public land to landless citizens, breaking the power of great senatorial estates. He is clubbed to death by senators in the Forum — the first political murder in Rome since the kings. His brother Gaius (tribune 123–122 BC) goes further: grain subsidies, new colonies, extended citizenship. He too is killed, along with 3,000 supporters. The Gracchi open a century of political violence that will end only with Augustus.
130 BC Silk Road opens under Emperor Wu Zhang Qian's mission links China to Central Asia and Rome Emperor Wu of Han sent diplomat Zhang Qian on a mission to forge alliances in Central Asia around 130 BC. Though the military alliance failed, Zhang Qian returned with knowledge of previously unknown kingdoms and trade routes. This opened the Silk Road — the network of overland and maritime routes connecting China to Rome via Central Asia, Persia and the Middle East, carrying silk, spices, glass, and ideas for the next 1,500 years.
107 BC – 86 BC Gaius Marius — the new army Gaius Marius, elected consul seven times (unprecedented), reforms the Roman army by abolishing the property qualification for military service. The Roman legions are now professional soldiers equipped and paid by the state — loyal to their general, not to Rome. Marius defeats Jugurtha of Numidia (106 BC) and destroys two Germanic tribes threatening Italy (Cimbri and Teutones, 102–101 BC). His army reforms, intended to strengthen Rome, create the conditions for a century of civil war.
105 BC Paper invented in China Cai Lun develops papermaking — the most transformative invention in history Although early forms of paper existed earlier, court official Cai Lun standardised and improved papermaking around 105 AD using bark, hemp, rags and fishing nets. Paper replaced heavy bamboo and silk as the writing medium of choice. It spread along the Silk Road to the Islamic world by the 8th century and to Europe by the 12th century, eventually enabling the printing press and the information revolution of the Renaissance.
88 BC – 78 BC Sulla — first march on Rome Lucius Cornelius Sulla, a general of the optimates faction, marches his legions on Rome in 88 BC after the popular assembly strips him of his eastern command — the first time a Roman general uses his army against the city itself. He captures Rome, kills his opponents, and departs for the east. On his return in 83 BC he wins a civil war, is appointed dictator, and carries out the first proscriptions — published death lists of political enemies. He resigns voluntarily in 79 BC. The precedent of using army against city is now set.
73 BC – 71 BC Spartacus — the slave revolt Spartacus, a Thracian gladiator, leads the largest slave revolt in Roman history from 73 to 71 BC. Starting with 70 gladiators who break out of a school in Capua, the revolt grows to an army of perhaps 120,000. For two years Spartacus defeats Roman forces repeatedly, twice breaking out of encirclement in southern Italy. Crassus finally defeats him; 6,000 captured rebels are crucified along the Appian Way from Capua to Rome — one every 35 metres.
63 BC Catilinarian Conspiracy Lucius Sergius Catilina, a failed consular candidate, plots to seize Rome by force. Cicero, consul in 63 BC, uncovers the plot through informers and delivers four speeches against Catiline in the Senate — the Catilinarian Orations — still considered the finest forensic rhetoric in Latin. The conspirators are arrested and executed without trial on Senate authority; Cicero is later exiled for this illegality. Catiline dies in battle in 62 BC. The episode reveals both Cicero's greatness and the Republic's fragility.
60 BC – 53 BC First Triumvirate — Caesar, Pompey, Crassus Julius Caesar, Pompey the Great and Marcus Licinius Crassus form an informal alliance in 60 BC to dominate Roman politics. Caesar gets the consulship and a command in Gaul; Pompey gets ratification of his eastern settlements and land for his veterans; Crassus gets tax-farming contracts in Asia. The alliance is renewed at the conference of Luca in 56 BC. It begins to disintegrate when Crassus dies at the Battle of Carrhae (53 BC) — defeated by the Parthians, his severed head used as a prop in a performance of Euripides.
58 BC – 50 BC Caesar's Gallic Wars Julius Caesar conquers Gaul (modern France, Belgium and parts of Germany and Switzerland) in a series of campaigns from 58 to 50 BC, recorded in his own Commentarii de Bello Gallico — still used to teach Latin. He bridges the Rhine twice, makes two expeditions to Britain, and suppresses the great revolt of Vercingetorix (52 BC), culminating in the siege of Alesia. The conquest kills perhaps one million Gauls and enslaves another million. Caesar enriches himself enormously and acquires an army of hardened veterans loyal to him personally.
49 BC – 45 BC Caesar's Civil War On 10 January 49 BC, Julius Caesar crosses the Rubicon river — the boundary of his province — with his army, an act of war against the Roman state. "Alea iacta est" — the die is cast. Pompey and the Senate flee Italy. Caesar defeats Pompeian forces in Spain, then pursues Pompey to Greece, winning the decisive battle of Pharsalus (48 BC). Pompey flees to Egypt and is murdered on arrival. Caesar defeats the remaining Pompeian forces at Thapsus (46 BC) and Munda (45 BC). He is master of the Roman world.
44 BC Assassination of Julius Caesar On the Ides of March (15 March) 44 BC, Julius Caesar is stabbed 23 times on the floor of the Theatre of Pompey by a group of senators — the Liberatores — led by Brutus and Cassius. Caesar had been appointed dictator perpetuo (dictator in perpetuity) weeks earlier, making a return to republican government impossible in their view. Mark Antony's funeral oration turns the crowd against the assassins. Caesar's assassination, intended to save the Republic, instead destroys it — the civil wars that follow end with Octavian as Augustus.
43 BC – 36 BC Second Triumvirate — Octavian, Antony, Lepidus Octavian (Caesar's heir), Mark Antony and Lepidus form a legal triumvirate in 43 BC with extraordinary powers. They immediately publish proscription lists: 300 senators and 2,000 equestrians are condemned. Among those killed is Cicero, whose severed head and hands are displayed on the Rostra in the Forum. At Philippi (42 BC) they defeat Brutus and Cassius, both of whom commit suicide. The triumvirs divide the Roman world — Antony takes the east, Octavian the west, Lepidus Africa.
31 BC Battle of Actium On 2 September 31 BC, Octavian's fleet under Agrippa defeats the combined fleet of Mark Antony and Cleopatra VII at Actium off the western coast of Greece. Antony and Cleopatra flee to Egypt; Octavian pursues. Antony commits suicide on a false report of Cleopatra's death; Cleopatra kills herself — tradition says by asp — rather than be paraded in Octavian's triumph. Egypt becomes a Roman province. Octavian is the last man standing. The Republic is over.
27 BC – 14 Augustus — the reign Augustus rules from 27 BC to 14 AD — 41 years — transforming Rome from a city of brick to a city of marble. He creates a standing army with fixed pay and terms, a praetorian guard, a professional civil service, and a system of provinces governed by his legates. He reforms taxation, builds roads, reorganises the calendar and patronises Virgil, Horace, Livy and Ovid. The Pax Augusta — Roman peace — begins. His succession is troubled: he outlives three designated heirs before Tiberius succeeds him.
27 BC Augustus becomes first Emperor On 13 January 27 BC, Octavian returns his powers to the Senate in a carefully staged performance of republican modesty. The Senate, gratefully, returns them — and adds the honorific "Augustus" (the revered one). Augustus never calls himself emperor or king; he is princeps (first citizen) and holds a collection of republican offices simultaneously. The fiction of the restored Republic is maintained for centuries, but power is unambiguous: Augustus rules Rome for 44 years and transforms it utterly.
19 BC Virgil completes the Aeneid Publius Vergilius Maro — Virgil — dies in 19 BC leaving the Aeneid, Rome's national epic, incomplete. He had worked on it for eleven years on Augustus's commission. The poem traces the Trojan hero Aeneas — ancestor of Romulus and of the Julian family — from the fall of Troy to the founding of Rome's destiny in Italy, weaving myth, history and political flattery into twelve books of Latin hexameter. It becomes the central text of Roman education and will shape Western literature for two millennia.
