There are empires that rise and fall. And then there is the Roman Empire – a state that lasted for over 1,200 years, left its mark on three continents, and whose legacy we encounter every day: in our legal systems, in the architecture of European cities, in the languages we speak, and in the roads we travel on.

Reading time approx. 15 mins.From a small settlement on the banks of the Tiber in the 8th century BC to the fall of the Western Roman Empire in 476 AD – and then on as the Byzantine Empire until 1453 – the history of Rome is one of the most extraordinary in human history. This article explains how that came about.
Key points at a glance:
- The Roman Empire went through three major phases: the monarchy (753–509 BC), the Republic (509–27 BC) and the Empire (from 27 BC).
- Under Emperor Trajan, it reached its greatest extent in 117 AD – covering some 5 to 6.5 million square kilometres.
- The division of the empire under Theodosius I (395 AD) marked the end of its ancient unity: the West fell in 476 AD, whilst the East survived as the Byzantine Empire until 1453.
- At its peak, around 70–80 million people lived in the empire – roughly a third of the world’s population at the time.
- Latin, Roman law and over 80,000 km of roads continue to shape Europe to this day.
Origins and early history: From legend to city
The history of Rome begins with a legend – and that is no coincidence. Romulus and Remus, the legendary twins, are said to have founded the city in 753 BC. This mythical tale, handed down by Livy and Virgil, contrasts with the archaeological evidence: settlements dating back to the 10th–9th centuries BC have been found on the Palatine Hill. The Latins and Sabines settled here, drawn by the favourable location at the Tiber ford – a natural crossing that facilitated both trade and control.
The Royal Period (753–509 BC)
The early city was ruled by seven kings. The Etruscan rulers in particular – Tarquinius Priscus and Tarquinius Superbus – drove forward the city’s expansion and contributed their engineering expertise:
| Structure | Function | Significance |
|---|---|---|
| Roman Forum | Political centre | Meeting place and market |
| Cloaca Maxima | Sewer system | Technical innovation |
| Temple of Jupiter | Religious centre | Capitol |
Transition to the Republic
By 509 BC, enough was enough. The Romans drove out Tarquinius Superbus because of his tyranny and established a new order: the Republic. Two consuls elected annually as the highest magistrates, the Senate as the advisory body of the nobiles, and popular assemblies (comitia centuriata, comitia tributa). A system of checks and balances – at least in theory.
In practice, a struggle over power raged from the very beginning. The patricians held power, the plebeians demanded a share. In 494 BC, the latter secured the office of tribune of the people through the secession march. The source material for this early period remains problematic: Livy’s work *Ab urbe condita* was not written until the 1st century BC, centuries after the events it describes.
The Republic: From City-State to Mediterranean Power
What follows is one of the most astonishing success stories of antiquity. In the space of a few centuries, a city-state in central Italy became the dominant power in the entire Mediterranean region.
Expansion in Italy
The path was anything but straightforward. The Gallic invasion of 390 BC – when Celtic warriors under Brennus sacked the city – demonstrated Rome’s vulnerability. The response: systematic expansion and a sophisticated system of alliances.
- Latin War (340–338 BC): Subjugation of the Latin allies
- Samnite Wars (343–290 BC): control of central Italy
- Pyrrhic Wars (280–275 BC): Victory over the Greek king Pyrrhus
By 272 BC, the whole of central and southern Italy was under Roman control. The socii (allies) retained internal autonomy but were required to provide troops – a system that allowed Rome’s armies to grow steadily.
The Punic Wars: The Struggle for the Mediterranean
The most dangerous adversary was Carthage. Three wars decided supremacy in the western Mediterranean:
- First Punic War (264–241 BC): Battle for Sicily. Rome built a naval fleet for the first time – and won off the Aegadian Islands using the innovative corvus technique (boarding bridges that turned naval battles into close-quarters combat).
- Second Punic War (218–201 BC): Hannibal’s legendary crossing of the Alps with 37 elephants and Rome’s crushing defeat at Cannae (up to 50,000 Roman casualties) brought the empire to the brink of collapse. Scipio’s victory at Zama in 202 BC saved it.
- Third Punic War (149–146 BC): Carthago delenda est. The complete destruction of Carthage finally put an end to the Punic threat.
Eastern expansion
| Region | Period | Event |
|---|---|---|
| Macedonia | 214–148 BC | Macedonian Wars, victory over Perseus |
| Seleucid Empire | 190 BC | Victory over Antiochus III at Magnesia |
| Greece | 146 BC | Destruction of Corinth, Province of Achaea |
| Asia Minor | 133 BC | Legacy of the Kingdom of Pergamon |
Revolution, civil wars and the end of the Republic
Expansion comes at a price. Large estates emerged, small farmers lost their livelihoods, and slave revolts in Sicily bore witness to growing tensions. From the late 2nd century BC onwards, the lust for power and social inequality tore the Republic apart.
The Gracchi: Reform with a fatal outcome
The brothers Tiberius and Gaius Gracchus attempted to resolve the social upheavals through political means. Tiberius (133 BC) sought to limit land ownership to 500 iugera with the Lex Sempronia Agraria – the Senate responded with violence, and Tiberius was murdered. Gaius (123–121 BC) fared no better: he extended the reforms to include grain laws, and over 3,000 of his supporters died. The precedent for political violence had been set.
Marius, Sulla and the legionary principle
Gaius Marius fundamentally reformed the army: even landless citizens could now serve. The army became a professional force – loyal to the commander who paid them, not to the Senate.
Sulla was the first to demonstrate this in 88 BC: he marched on Rome with his legions. His dictatorship (82–79 BC) brought proscription lists, on which hundreds of citizens were declared outlaws, as well as constitutional reforms to strengthen the Senate. The pattern was clear: whoever commanded the legions could rule Rome.
Caesar, the Rubicon and the Ides of March
The First Triumvirate (60 BC) comprising Caesar, Pompey and Crassus was an informal division of power. Caesar’s Gallic War (58–51 BC) brought fame, wealth and loyal veterans – at the cost of an estimated one million Gauls killed or taken prisoner.
Crossing the Rubicon in 49 BC – Alea iacta est – triggered the civil war. Following his victory at Pharsalus in 48 BC, Caesar became dictator for life. On 15 March 44 BC, he was assassinated by 60 senators led by Brutus and Cassius. The civil wars continued nonetheless.
Augustus: The Republic as a Disguise
The Second Triumvirate (43 BC), comprising Octavian, Antony and Lepidus, eliminated Caesar’s assassins at Philippi in 42 BC. The final power struggle ended in 31 BC at Actium. In 27 BC, Octavian assumed the title ‘Augustus’ – and established a monarchy in republican guise. The Principate was born.
The Imperial Era: High Point and Dynasties
Augustus and the foundations of the empire
| Area | Measure |
|---|---|
| Military | A professional army of 28 legions (approx. 150,000 men) plus auxiliary troops |
| Administration | Distinction between senatorial and imperial provinces |
| Ideology | Pax Augusta – peace following decades of civil war |
| Propaganda | SPQR – the Senate and the People of Rome as a single entity |
Dynasties of the early Imperial period
Julio-Claudian dynasty (14–68 AD): Tiberius led a frugal but stable administration. Caligula’s brief reign ended in chaos. Claudius conquered Britain in 43 AD. Following the Great Fire of Rome in 64 AD, Nero ordered the first persecutions of Christians – his suicide in 68 AD triggered the Year of the Four Emperors in 69 AD.
Flavian dynasty (69–96 AD): Vespasian stabilised the empire and began construction of the Colosseum. Titus witnessed the eruption of Vesuvius in 79 AD, which buried Pompeii and Herculaneum under ash – and today provides us with one of the most fascinating archaeological insights into everyday Roman life. Domitian ended his reign as a tyrant, murdered.
The Adoptive Emperors: Rome’s Golden Century
The Adoptive Emperors (96–192 AD) – Nerva, Trajan, Hadrian, Antoninus Pius, Marcus Aurelius and Commodus – led the empire to its zenith.
- Trajan expanded the empire to its greatest extent: Dacia (101–106 AD) with its rich gold mines, Mesopotamia (114–117 AD) as far as the Persian Gulf – a total of around 5 million square kilometres.
- Hadrian consolidated the borders rather than expanding further. Hadrian’s Wall in Britain (122 AD, 117 km long) marked the northern frontier of the empire.
- Marcus Aurelius, the philosopher-emperor and Stoic, spent much of his reign on the Danube front against Germanic peoples – and wrote his Meditations whilst doing so.
- Commodus (180–192 AD) brought this golden age to a chaotic end.
The crisis of the 3rd century: Almost the end
From 235 to 284 AD, the Empire experienced an era that nearly destroyed it. Around 25 soldier-emperors succeeded one another in 50 years – many reigned for only months before being assassinated. At the same time, the Alemanni and Goths pressed in from the outside, the Sassanids in the east became more dangerous, and Emperor Valerian was even taken prisoner in 260 AD. Internally, the currency collapsed:
- the denarius lost up to 95% of its silver content – inflation and economic decline followed
- Separate kingdoms such as the Imperium Galliarum (260–274 AD) threatened the empire’s unity
- The tax system collapsed; payments in kind replaced monetary payments
The empire survived – but it was no longer the same.
Late Antiquity: Reform, Christianity and the Division of the Empire
Diocletian’s reforms
Emperor Diocletian (284–305 AD) reorganised the empire from the ground up. His concept: divide power, streamline administration, professionalise the military.
| Reform | Implementation |
|---|---|
| Tetrarchy | Two Augusti and two Caesars shared power |
| Administration | Approx. 100 smaller provinces, grouped into 12 dioceses |
| Military | Separation of civil and military authority |
| Economy | Price edict (Edictum maximum) – failed |
Constantine the Great: A vision changes the world
The victory at the Milvian Bridge in 312 AD is one of the turning points in European history. Constantine is said to have had a vision before the battle – In hoc signo vinces (In this sign you will conquer). Whether vision or political calculation: the Edict of Milan in 313 AD brought tolerance to Christians and permanently altered the history of religion in Europe.
- 330 AD: Founding of Constantinople as the new capital on the Bosporus
- 325 AD: Council of Nicaea – the first empire-wide church assembly
- Introduction of the solidus – a new gold currency that remained stable for centuries
Theodosius, the division of the empire and the Migration Period
Emperor Theodosius I (379–395 AD) made Christianity the state religion (Edict of Thessalonica 380 AD) and banned pagan cults in 391 AD. After his death in 395 AD, he divided the empire among his sons – this division was final.
The invasion of the Huns in 375 AD had triggered a chain reaction. Gothic groups won a crushing victory at Adrianople in 378 AD – Emperor Valens fell, and some 20,000 Roman soldiers died. The foederati system (land in exchange for military service) was intended to be the solution. It was not enough.
The Fall of the Western Roman Empire
- 410 AD: Alaric’s Visigoths sack Rome – for the first time in 800 years
- 455 AD: Geiseric’s Vandals sacked Rome once again
- Loss of provinces: Britannia, Hispania and Africa are lost
- 476 AD: Odoacer deposed the last Western Roman Emperor, Romulus Augustulus
Germanic successor kingdoms emerged on the territory of the Western Roman Empire – and the Middle Ages began.
The Eastern Roman Empire: Byzantium survives
The East survived as the Eastern Roman Empire. Emperor Justinian I (527–565 AD) attempted to reconquer the West – with partial success in Italy, North Africa and parts of Spain. His lasting legacy was the Corpus iuris civilis: the codification of Roman law in 50 volumes comprising 4.6 million words – a work that continues to shape legal scholarship to this day.
In the 7th century, the Persian Wars and Arab expansion fundamentally transformed the empire. Emperor Heraclius (610–641 AD) introduced Greek as the official language and adopted the title ‘Basileus’. The Byzantine Empire lasted until 1453, when the Ottomans conquered Constantinople.
Society, Population and Daily Life
Behind the battles and dynasties lay the lives of millions. Roman society was hierarchical – yet surprisingly fluid by ancient standards.
Social classes
| Class | Description | Wealth / Status |
|---|---|---|
| Ordo senatorius | Senators | At least 1.5 million sesterces |
| Ordo equester | Knights, merchants | At least 400,000 sesterces |
| Decuriones | Urban elites | Local offices |
| Plebs | Free citizens | Labourers, craftsmen |
| Liberi | Manumitted slaves | Social mobility possible |
| Servi | Slaves | 10–20% of the population |
Cities, figures, life
At its peak, the empire had a population of around 70–80 million – a third of the world’s population at the time. The city of Rome exceeded one million inhabitants, Alexandria reached 500,000, and Antioch and Carthage each had over 200,000 inhabitants.
Average life expectancy was 20–30 years – largely due to the extremely high infant mortality rate (around 50% died before the age of five). Those who survived childhood could well live to be 50 or older. The pater familias theoretically exercised lifelong authority over his family.
Urban and rural life
- Insulae: tenement blocks with 5–6 storeys – cramped, fire-prone, noisy
- Domus: upper-class townhouses with an atrium and peristyle
- Thermae: Not just bathing – but sport, shops, socialising
- Entertainment: The Colosseum held 50,000 spectators for gladiatorial combats, the Circus Maximus 250,000 for chariot races
The military as a route to social advancement
The army offered a real opportunity for non-citizens. Auxiliary soldiers were granted Roman citizenship after 20–25 years of service – documented on bronze tablets, the diplomata militaria. Veteran colonies on the borders Romanised entire regions.
Administration, economy and infrastructure
Economy
| Sector | Significance |
|---|---|
| Agriculture | 80% of the population; cereals, wine, olives |
| Mining | Hispanic silver (Rio Tinto: approx. 20,000 kg/year), gold from Dacia |
| Trade | Mediterranean trade, links to India and China |
| Crafts | Pottery (terra sigillata), textiles, metalwork |
With the Constitutio Antoniniana (212 AD), Emperor Caracalla granted citizenship to almost all free inhabitants of the empire – the tax base grew from 4–5 million to 30–50 million citizens.
Infrastructure: Rome’s true legacy
- Roads: Over 80,000 km of paved highways – the Via Appia, the Via Egnatia and dozens more. Many modern routes still follow these routes today.
- Aqueducts: 11 aqueducts supplied Rome with 1,400 million litres of water daily
- Ports: Ostia and Portus (100 ha) as supply hubs for the capital
- Bridges: The Alcantara Bridge in Spain (48 m high) still stands today
Culture, language and law: What remains
Architecture and engineering
Roman culture was a synthesis – Greek philosophy, Etruscan engineering, Italic tradition. The result was something unique:
- Opus caementicium: Roman concrete made domes such as the Pantheon (43 m in diameter) possible – still in use today
- Arches and vaults revolutionised bridge and aqueduct construction
- Pompeii and Herculaneum, preserved by the eruption of Vesuvius in 79 AD, reveal Roman daily life in a level of detail found nowhere else
Language
Latin was the official language in the West, whilst Greek dominated the East. The Romance languages – Italian, French, Spanish, Portuguese and Romanian – emerged from spoken Vulgar Latin in the Middle Ages. The Latin heritage lives on in each of these languages; in Italian, for example, around 85% of the vocabulary has Latin roots. Latin itself remained a language of scholarship until the 20th century – in academia, the Church and diplomacy.
Roman law: the most invisible legacy
- The Twelve Tables (451 BC): The first written codification of law
- Classical jurists (1st–3rd centuries AD): Gaius, Ulpian and Paulus laid the foundations
- Corpus iuris civilis (529–534 AD): Justinian’s codification in 50 volumes, 4.6 million words
The German Civil Code (BGB), the French Civil Code (Code civil), the Austrian Civil Code (ABGB), the legal systems of Latin America – they are all based on Roman principles. Every time you sign a contract or go to court, you are operating within the Roman legal tradition.
Political legacy
| Rulers / Empire | Links to Rome |
|---|---|
| Charlemagne (800 AD) | Coronation by the Pope |
| Holy Roman Empire (962–1806) | Claimed imperial continuity |
| Russian tsars | Moscow as the ‘Third Rome’ |
| Napoleon | Imperial title, Roman symbolism |
FAQ on the Roman Empire
How large was the Roman Empire at its peak?
Under Emperor Trajan, the Empire reached its greatest extent in 117 AD, covering approximately 5 to 6.5 million square kilometres. Its borders stretched from Hadrian’s Wall in Britain to the Euphrates, and from the Rhine-Danube line to the Sahara. It fully encompassed what is now Italy, Spain, Portugal, France, Belgium, Switzerland, Austria, the Balkan states, Romania, Greece, western Turkey, Syria, Israel, Jordan, Egypt, Tunisia, England and Wales.
What was life like for children in the Roman Empire?
Roman law placed children under the guardianship of the pater familias. Childhood ended early – at the age of 14, boys donned the toga virilis. The reality varied greatly according to social class: slave children worked from an early age, whilst children of the upper classes received tuition from a grammaticus and a rhetor. Typical children’s games included ball games (pila), dice (talus) and board games (duodecim scripta). The high infant mortality rate had a profound impact on family life.
Was there freedom of religion in the Roman Empire?
In principle, Rome tolerated various cults as long as they were considered religio licita and did not disturb public order. Conflicts arose with religions that rejected the worship of the state gods. Christians were persecuted at times – under Nero in 64 AD, Decius in 250 AD and Diocletian in 303 AD. The Edict of Milan in 313 AD brought tolerance, and Theodosius I made Christianity the state religion in 380 AD.
How could one become a Roman citizen?
Through 25 years’ service in auxiliary troops, through manumission by a Roman citizen, through collective conferral on cities, or through special merits. The Constitutio Antoniniana (212 AD) ultimately granted citizenship to almost all free inhabitants of the empire – mainly to broaden the tax base.
What traces of the Roman Empire are still visible today?
The Colosseum, the Roman Forum and the Pantheon in Rome. The Porta Nigra in Trier (30 m high). The Pont du Gard in southern France (just under 50 m high, 275 m long). In Germany: Xanten, the Saalburg, the Limes. Many roads in Italy still follow Roman routes today – and the Rheinisches Landesmuseum in Trier houses one of the most significant collections of Roman artefacts north of the Alps.
What does the Roman Empire have to do with LARP and re-enactment?
A great deal. Antiquity – particularly the Roman Empire – is one of the most popular settings in the reenactment scene worldwide. Legionaries, auxiliary troops, Celtic and Germanic warriors, merchants in the Forum, gladiators: the social and military diversity of the Empire offers an enormous range of characters. Anyone wishing to participate in this setting needs historically accurate equipment – from the lorica segmentata to the scutum, from the caligae to the tunica. At vehi-mercatus you will find clothing and accessories for historically authentic portrayals of this era.
Conclusion: Rome did not fall – it transformed
Anyone walking through European cities today, driving along Roman roads or studying laws is moving amidst Roman heritage. The Roman Empire has no successors – it laid the foundations. For our languages, our law, our architecture, our thinking about rule and the state.
Over 1,200 years passed between the founding of Rome and the fall of the Western Roman Empire. No other ancient civilisation has shaped Europe to such an extent. And the search for its traces continues to this day – from Trier to Egypt, from Britain to Syria.
