A Journey Through the Ages
Rome grew from a central Italian city-state into a Mediterranean empire whose political institutions, laws, languages, religions, and cities shaped societies across Europe, North Africa, and western Asia.
Its history spans the traditional monarchy, nearly five centuries of republican government, and an imperial system established by Augustus in 27 BCE.
The western imperial court disappeared in the fifth century, but Roman government continued from Constantinople for almost another thousand years.
This overview follows eight broad eras, from Rome’s legendary foundation in 753 BCE to the Ottoman conquest of Constantinople in 1453 CE.
753–509 BCE
From a settlement on the Tiber to a city ruled by kings.
Roman tradition placed the city’s foundation in 753 BCE. The regal period blended Latin, Sabine, and Etruscan influences while developing assemblies, priesthoods, military organization, and major public works. The monarchy ended, according to the conventional chronology, when the last Tarquin was expelled and annually elected magistrates replaced kingship.
Romulus, Remus and the she-wolf gave Rome a founding story that later Romans retold for centuries.
Numa Pompilius was credited with Rome’s priesthoods, calendar and sacred customs.
Under kings of Etruscan background Rome drained its valleys, raised temples and grew into a true city.
The expulsion of Tarquinius Superbus left a lasting Roman hostility to the title of king.
509–264 BCE
A new republic that conquered Italy while arguing over who should rule.
The early Republic developed through conflict and compromise. Plebeian secessions won political safeguards, written law made civic rules more visible, and new magistracies broadened participation among Roman citizens. At the same time, repeated wars and negotiated alliances extended Roman power through Latium and central Italy.
Plebeian secessions forced the patricians to share offices, legal protections and, in time, lawmaking power.
The Gallic sack of c. 390 BCE humiliated Rome, which rebuilt its walls and its army.
Wars against the Samnites and a web of alliances made Rome master of the peninsula.
The Via Appia and new colonies bound conquered territory to the city.
264–133 BCE
Three wars with Carthage turned an Italian power into a Mediterranean empire.
The Punic Wars forced Rome to build fleets, maintain armies overseas, and govern its first provinces. Hannibal brought the Republic close to disaster at Cannae, but Rome endured and defeated Carthage at Zama. Campaigns in Greece and Macedonia followed, while conquest created enormous wealth and deep social strain at home.
Rome built its first great fleets to fight Carthage for Sicily and won the First Punic War.
Hannibal crossed the Alps and won crushing victories, yet Rome refused to make peace.
Victories over Macedon drew Rome deep into the politics of the Greek world.
The destruction of Carthage and Corinth confirmed Roman supremacy and brought vast wealth and new strains.
133–27 BCE
Reformers, generals and civil wars brought down the Republic.
Land reform, citizenship, and the distribution of imperial wealth divided Roman politics. Commanders increasingly used armies loyal to them personally, leading to dictatorship, proscriptions, and civil war. Caesar’s assassination failed to restore the old order; Octavian’s victory at Actium allowed him to build a durable monarchy behind republican forms.
The deaths of the Gracchi showed that political disputes could now be settled by force.
Marius opened the legions to the poor, and soldiers began to look to their commanders for reward.
The Social War forced Rome to extend citizenship to its Italian allies.
Caesar’s dictatorship and murder opened a final round of civil war that ended at Actium.
27 BCE–235 CE
Two centuries of imperial rule, prosperity and expansion.
The Principate concentrated military and political authority in the emperor while retaining the Senate and traditional offices. Roman law, citizenship, trade, and urban culture spread across a vast network of provinces. Dynastic instability and civil war still occurred, but the first two centuries of imperial rule included long periods of prosperity and effective administration.
After the Teutoburg disaster, Rome largely held the line of the Rhine and Danube.
Claudius invaded Britain and Trajan annexed Dacia, pushing the empire toward its widest extent.
Rome crushed the Jewish revolt and destroyed the Second Temple in 70 CE.
Hadrian consolidated the empire, building walls and fortified lines along its borders.
235–395 CE
From near-collapse to a reorganized, Christian empire.
After 235, emperors rose and fell through military revolt while frontier invasions, plague, and inflation strained the state. Aurelian restored political unity, and Diocletian reorganized taxation, administration, and imperial rule. Constantine reunited the empire, founded Constantinople, and favored Christianity, reshaping Roman institutions for late antiquity.
Emperors fell in quick succession, and Decius died fighting the Goths at Abritus.
Diocletian shared power among four rulers and reorganized the provinces, army and taxation.
Constantine refounded Byzantium as Constantinople, a new imperial center in the East.
Persecution gave way to toleration, imperial councils and, under Theodosius, Nicene Christianity as the official faith.
395–717 CE
The West gave way to new kingdoms while Constantinople endured.
Fifth-century western emperors lost authority to military strongmen and successor kingdoms, while the eastern court remained wealthy and administratively resilient. Justinian’s armies recovered Africa and Italy, his jurists systematized Roman law, and Hagia Sophia embodied imperial ambition. Plague and long wars weakened those gains before Arab conquests removed Syria, Egypt, and much of the Mediterranean coast.
Goths and Vandals sacked Rome, and in 476 the last western emperor was deposed.
Justinian’s generals recovered North Africa and Italy, though the gains proved costly to hold.
The Justinianic plague and the Lombard invasion of Italy undid much of the reconquest.
A last great war with Persia was followed by Arab conquests of Syria, Egypt and North Africa.
717–1453 CE
Seven more centuries of Roman rule from Constantinople.
Eastern Rome checked major sieges, reorganized its provinces, and experienced renewed strength under the Macedonian and Komnenian dynasties. Loss at Manzikert accelerated Turkish settlement in Anatolia, while tension with Latin Christendom culminated in the Fourth Crusade’s sack of Constantinople. The empire was restored in 1261 but survived as a diminished regional power until Mehmed II captured the capital in 1453.
Emperors and churchmen fought for over a century over the place of holy images in worship.
Under the Macedonian dynasty the empire recovered Crete and conquered Bulgaria.
Alexios I and his successors rebuilt the empire after Manzikert as crusaders crossed its lands.
Restored in 1261, the empire was weakened by civil war as the Ottomans crossed into Europe.

Rome fell as a political power in the West in 476 and in the East in 1453, but almost nothing else about it ended. Its law, language, engineering, and idea of the state were absorbed so thoroughly into later civilizations that they rarely read as "Roman" anymore - they just read as normal.
Justinian's 6th-century codification of Roman law, the Corpus Juris Civilis, became the basis of civil law systems across continental Europe and, through colonization, much of the world. Concepts like citizenship, the republic, the senate, and codified statute all trace back to Roman practice.
Latin gave rise to the Romance languages - Italian, French, Spanish, Portuguese, and Romanian - and supplied the vocabulary of law, science, and the Church across Europe for over a millennium after the western empire fell. Its alphabet is the one this page is written in.
Roman roads, aqueducts, concrete, and urban planning connected and supplied a Mediterranean-wide network of cities. Some Roman roads and bridges are still in use today, and Roman concrete - like the dome of the Pantheon - has outlasted nearly two thousand years of weather.
Constantine's adoption of Christianity reshaped the empire and the religious map of Europe. In the East, the empire survived as Byzantium for another millennium, preserving Greek and Roman learning, codifying Orthodox Christian culture, and transmitting classical texts that would later feed the Renaissance.
The timeline is built from the project's own research and its event and ruler datasets. The datasets are a work in progress: linked articles are starting points for verification, not proof that every claim has been independently checked. Dates for the regal period and the early Republic are traditional, and ancient figures for armies, casualties and populations vary widely between sources.
Every event has its own sources. See Sources & Further Reading in each timeline entry and ruler profile.
