Ancient Europe: Greece and Rome

TL;DR. Two ancient civilizations did more than any others to shape the Europe we know: Greece and Rome. The Greeks were never a single country but a scattering of independent city-states, most famously Athens, which experimented with democracy, and Sparta, built around its army. Greek thinkers, artists, and writers laid foundations for philosophy, science, drama, and politics that are still used today. Rome began as a small city in Italy, grew into a republic governed by elected officials, then became a vast empire ruled by emperors. For centuries Rome brought a single system of law, roads, language, and government to lands from Britain to the Middle East. Christianity began as a small persecuted faith inside this empire and ended up its official religion. The western half of the empire collapsed in 476 CE, but its laws, languages, and ideas never really went away.

Key takeaways

  • Greece was not one nation but many independent city-states (called poleis), which sometimes cooperated and often fought one another.
  • Athens and Sparta were rivals with very different societies: Athens prized democracy, trade, and the arts, while Sparta organized almost everything around military strength.
  • The Greek city-states, allied together, twice fought off invasions by the much larger Persian Empire, then later exhausted themselves fighting each other in the Peloponnesian War.
  • Rome moved through three big phases: a legendary early kingdom, a long Republic run by the Senate and elected consuls, and finally an Empire ruled by one man.
  • The Pax Romana, a long stretch of relative peace, spread Roman law, roads, engineering, and the Latin language across three continents.
  • The "fall of Rome" in 476 CE refers only to the western half. The eastern half, later called the Byzantine Empire, carried on for almost another thousand years.

Before the city-states: the Bronze Age Greeks

Long before classical Greece, two earlier cultures rose and fell around the Aegean Sea. The first was the Minoan civilization, centered on the large island of Crete from about 2000 to 1450 BCE. Named after the legendary King Minos, the Minoans built sprawling palace complexes, the most famous at a site called Knossos. They were skilled traders and sailors, painted lively frescoes (wall paintings) of dolphins and athletes, and used a still-undeciphered script. We do not fully know why their civilization declined, though earthquakes, a massive volcanic eruption on the nearby island of Thera, and outside attack have all been suggested.

On the Greek mainland, a second culture, the Mycenaeans, rose from about 1600 to 1100 BCE. They were a warrior society living in fortified hilltop centers such as Mycenae, the city that gives them their name. They wrote in an early form of Greek, traded widely, and are the likely real-world memory behind the great Greek poems about the Trojan War, the Iliad and the Odyssey. Around 1100 BCE, Mycenaean society collapsed for reasons still debated, and Greece entered a poorly recorded stretch sometimes called the "Dark Age," when writing and large-scale building largely disappeared.

Don't be confused: the Greeks of the Bronze Age (Minoans and Mycenaeans) came hundreds of years before the famous Greece of Athens, Sparta, and the philosophers. There is a long gap between them. When people say "ancient Greece," they usually mean the later classical period, roughly 500 to 300 BCE.

The rise of the city-states

When Greece recovered, it organized itself in a distinctive way. Instead of one kingdom, hundreds of small, independent communities grew up, each based on a city and the farmland around it. The Greek word for such a community is polis (plural poleis), usually translated as "city-state." Each had its own government, laws, army, and gods, even though all shared a common Greek language and religion. They competed, traded, and sometimes warred, and they founded colonies all around the Mediterranean and Black Seas, spreading Greek culture far and wide.

The Greeks felt a shared identity in some ways. They gathered for athletic festivals, most famously the Olympic Games, held every four years from 776 BCE in honor of the god Zeus, and they consulted shared religious sites such as the oracle at Delphi. But politically they stayed fiercely separate. Two city-states stood out, and they could hardly have been more different.

Athens sat in a region called Attica and grew wealthy through trade and its powerful navy. Over time it developed an early form of democracy, a word from the Greek for "rule by the people." Beginning with reforms around 508 BCE, adult male citizens could vote directly on laws and policies in a large public assembly. This was a narrow democracy by modern standards: women, enslaved people, and foreigners could not vote, and they made up most of the population. Even so, the idea that ordinary citizens, not just kings or nobles, should decide public matters was a turning point in history.

Sparta, in the southern region of the Peloponnese, took the opposite path. It was a militarized society organized for war. Spartan boys were taken from their families and trained as soldiers from childhood, and adult male citizens devoted their lives to the army. This was made possible by a large enslaved population called helots, who farmed the land so that Spartans could focus on fighting. Sparta was governed by a mix of two hereditary kings, a council of elders, and elected officials, but its whole way of life pointed toward discipline and military strength rather than trade or the arts.

The Persian Wars: Greeks against an empire

In the early 400s BCE, the Greek city-states faced a common threat. To the east lay the Persian Empire, the largest the world had yet seen, stretching across modern Iran, Iraq, Turkey, Egypt, and beyond. When Greek cities on the coast of Asia Minor (today's Turkey) rebelled against Persian rule, Athens sent help. In response, the Persian kings decided to punish and conquer mainland Greece.

The first invasion came in 490 BCE. A Persian force landed at a plain called Marathon, near Athens. Here Athens, with support from the small city of Plataea, met the Persians in battle. Against expectations, the heavily armored Greek infantry, called hoplites, defeated the larger Persian army. Tradition says a runner carried news of the victory back to Athens, the origin of the modern marathon race, though that story may be a later legend.

Ten years later, in 480 BCE, the Persians returned in far greater numbers under King Xerxes. This time many Greek city-states, who normally quarreled, allied together against the common enemy. At the narrow mountain pass of Thermopylae, a small Greek force led by Sparta and its King Leonidas held off the huge Persian army for days before being overwhelmed, buying time for the rest of Greece. The Persians pushed on and burned Athens, whose people had fled. But the allied Greek navy, with Athens providing the largest fleet, trapped and crushed the Persian ships in the narrow waters of Salamis later that year. The following year (479 BCE), the combined Greek land army won a decisive victory at Plataea. The Persian invasions were over.

Don't be confused: the Greek city-states were never a single unified country, not even during the Persian Wars. They formed temporary military alliances against Persia, then went back to being independent and often hostile rivals once the danger passed.

Greek religion and shared culture

It helps to understand what tied the quarreling Greeks together. They worshipped the same family of gods, imagined as powerful, very human-like beings who lived on Mount Olympus. Among the best known were Zeus, the king of the gods; Athena, goddess of wisdom and the protector of Athens; Apollo, linked to the sun, music, and prophecy; and Poseidon, god of the sea. Stories about these gods, which we call Greek mythology, were not just entertainment. They explained the natural world, taught lessons about human behavior, and shaped festivals, temples, and art across every city-state.

The Greeks also shared a language, a system of writing using an alphabet, and a love of competition. The Olympic Games mentioned earlier were one of several great athletic and religious festivals where citizens from rival cities met in peace. They prized public speaking, debate, and the open exchange of ideas, habits that fed directly into both their politics and their philosophy. These shared threads are why we can speak of one "Greek culture" even though there was never one Greek state.

The Golden Age of Athens

After the Persian Wars, Athens entered a brilliant period often called its Golden Age, especially the years around 461 to 429 BCE when a leader named Pericles was the most influential figure in its democracy. Wealthy from trade and from leading an alliance of other city-states, Athens spent lavishly on art and public buildings. The most famous is the Parthenon, a grand marble temple to the goddess Athena that still stands on the hill called the Acropolis above the city.

This age also gave the world some of its most lasting ideas and art forms. Athenians invented drama as we know it, performing tragedies and comedies in large open-air theaters during religious festivals. Above all, this was the age of Greek philosophy, a word meaning "love of wisdom." Three thinkers in particular still shape education today:

  • Socrates (about 470 to 399 BCE), who taught by relentless questioning, pushing people to examine their beliefs. He wrote nothing down, and was eventually put to death by an Athenian court on charges of corrupting the young and disrespecting the gods.
  • Plato (about 428 to 348 BCE), a student of Socrates who founded a school called the Academy and wrote dialogues exploring justice, knowledge, and the ideal state.
  • Aristotle (384 to 322 BCE), a student of Plato who studied almost everything: logic, biology, politics, ethics, and physics. His writings guided European and Islamic thought for nearly two thousand years.

The Peloponnesian War

Athens's growing power and wealth made other city-states nervous, above all Sparta. After the Persian Wars, Athens had turned a defensive alliance of city-states, the Delian League, into something close to an empire, collecting tribute and dominating its members. Sparta led a rival alliance, the Peloponnesian League. The result was a long and ruinous conflict.

In the Peloponnesian War (431 to 404 BCE), the two sides and their allies were clearly drawn: the Athenian-led Delian League against the Spartan-led Peloponnesian League. Athens was strong at sea, Sparta on land, so neither could easily finish the other off. The war dragged on for decades, broken by truces and disasters, including a deadly plague that swept Athens early on and killed Pericles. A massive Athenian invasion of the island of Sicily ended in catastrophe. In the end, Sparta, helped by money from its former enemy Persia, built a fleet that defeated Athens. In 404 BCE Athens surrendered. No single city-state ever fully recovered the strength of earlier years, and the constant fighting left Greece weakened and divided.

Alexander the Great and the Hellenistic world

That weakness opened the door to a kingdom on Greece's northern edge: Macedon. Its king, Philip II, built a powerful professional army and brought most of the Greek city-states under his control. After Philip was assassinated in 336 BCE, his young son Alexander took the throne. In just over a decade he led one of the most remarkable military campaigns in history.

Alexander, often called Alexander the Great, invaded the Persian Empire and conquered it entirely, then pushed on into Egypt and as far east as India. He never lost a major battle. By the time he died of illness in 323 BCE, at only about 32 years old, he ruled an empire stretching from Greece to the borders of India. He left no strong heir, and his generals divided his lands among themselves into competing kingdoms.

His lasting effect was cultural. Greek language, art, city planning, and ideas spread across the whole eastern Mediterranean and Near East, blending with local cultures. Historians call this mixed civilization Hellenistic, from Hellas, the Greek word for Greece. The city of Alexandria in Egypt, which Alexander founded, became a center of learning with a famous library. For centuries after, educated people across this huge region spoke Greek and shared Greek ideas, which is one reason those ideas later reached Rome so easily.

Rome: from a small city to a republic

While the Greek world was rising and falling, a city was growing in central Italy. According to legend, Rome was founded in 753 BCE by Romulus, who, the story says, was raised along with his twin brother Remus by a she-wolf. This is a founding myth, not verified history, but it shows how Romans liked to imagine their origins. In its earliest period Rome was ruled by kings.

In 509 BCE, by tradition, the Romans overthrew their last king and founded a Republic, a form of government without a monarch in which officials are chosen rather than inheriting power. (The word comes from the Latin res publica, meaning "the public thing" or "public affair.") Real power rested with the Senate, a council of leading citizens, mostly from wealthy families, who advised and shaped policy. Each year the assembly of citizens elected two consuls, who served as joint heads of state and army commanders for a single year. Having two consuls who could each check the other, and limiting their term to one year, was a deliberate guard against any one person seizing kingly power.

Roman society was long divided between the patricians, the old noble families, and the plebeians, the ordinary citizens. Over time the plebeians won greater rights, including officials called tribunes who could protect their interests. Through a mix of warfare, alliances, and absorbing defeated peoples as partial citizens, Rome gradually conquered and unified the entire Italian peninsula.

Don't be confused: the Roman Republic and the Roman Empire are two different phases of the same state. In the Republic (509 BCE to 27 BCE) Rome was governed by the Senate and elected consuls, with no single ruler. In the Empire (from 27 BCE on) one man, the emperor, held supreme power. People often say "ancient Rome" for both, but the way it was governed changed completely.

The Punic Wars: Rome against Carthage

As Rome expanded, it collided with the other great power of the western Mediterranean: Carthage, a wealthy trading city in North Africa (near modern Tunis) with a strong navy. The two fought three conflicts known as the Punic Wars (from Punicus, the Latin word for the Carthaginians), running from 264 to 146 BCE. In all three, the alliance was the same: Rome against Carthage, each supported by its own allies and subject cities.

The First Punic War was fought largely at sea, mostly over the island of Sicily, and ended with Rome victorious and, for the first time, building a serious navy. The Second Punic War is the most famous, because of the Carthaginian general Hannibal. In a daring move, Hannibal marched an army, including war elephants, from Spain over the Alps into Italy itself and won a series of crushing victories, most famously at Cannae. Yet he could not capture Rome. The Romans eventually carried the war to North Africa, forcing Hannibal home, and defeated him at the Battle of Zama in 202 BCE. In the Third Punic War, Rome besieged and utterly destroyed the city of Carthage in 146 BCE. With its great rival gone, Rome became the dominant power across the entire Mediterranean.

The crisis of the Republic and the rise of Caesar

Conquest made Rome rich and powerful, but it also strained the Republic. Enormous wealth flowed to a few families, small farmers were pushed off their land, and the gap between rich and poor widened. Ambitious generals, commanding armies loyal to them personally rather than to the state, began to use force in politics. The last century of the Republic was marked by repeated civil wars and political violence.

The most famous figure of this crisis was Julius Caesar, a brilliant general who conquered Gaul (roughly modern France) and won enormous popularity. When ordered by political rivals in the Senate to give up his command, he instead marched his army into Italy in 49 BCE, igniting a civil war that he won. Caesar was then named dictator, an emergency office, but for life, which alarmed those who feared he meant to become a king. In 44 BCE a group of senators assassinated him, hoping to save the Republic. Instead, his death triggered yet another round of civil wars.

Augustus and the Roman Empire

Out of that final struggle, Caesar's adopted heir, a young man named Octavian, emerged victorious, defeating his rivals Mark Antony and the Egyptian queen Cleopatra. In 27 BCE the Senate gave him the honored title Augustus, meaning "revered one." Although he carefully kept the outward forms of the Republic, calling himself merely "first citizen," in practice Augustus held supreme power over the state and the army. Historians count him as the first Roman emperor, and his rise marks the change from Republic to Empire.

Augustus and his successors brought a long period of relative stability and peace across the Roman world, lasting roughly from 27 BCE to about 180 CE. It is known as the Pax Romana, Latin for "Roman Peace." This was not free of war, but the core of the empire enjoyed unusual calm, allowing trade and travel to flourish across a vast area unified under one government.

Rome's achievements in this period still shape daily life. Roman law, with its written codes and principles such as the idea that an accused person's case should be argued and judged, influences legal systems across the world today. Roman engineers built a network of stone roads so durable that some survive after two thousand years, along with aqueducts that carried water across long distances, public baths, and the great arena called the Colosseum. They spread the Latin language and an efficient system of administration, dividing their lands into provinces run by governors and linked by that road network.

Life in the Roman world

At its height the empire ruled tens of millions of people across three continents: most of Europe, North Africa, and the Middle East. What held such a sprawling territory together was not only the army but a shared way of life. Roman citizenship, once limited to the city of Rome, was gradually extended to more and more people in the provinces, and in 212 CE it was granted to nearly all free inhabitants of the empire. Citizenship brought legal rights and a sense of belonging to something larger than any single town.

Roman society was deeply unequal. At the top were wealthy landowning families; below them were ordinary free citizens, then a vast number of enslaved people, who did much of the work in fields, mines, and households. Slavery was woven through the whole economy, and Romans did not question it. Cities across the empire copied Roman ways, with forums (public squares), temples, theaters, and baths. Goods and people moved along the roads and across the Mediterranean, which Romans confidently called Mare Nostrum, meaning "our sea." This connected world is part of why a new religion, beginning in one small province, could eventually spread to every corner of the empire.

The rise of Christianity

During the early Empire, in a province called Judea, a new religion took shape around the teachings of Jesus of Nazareth, who was executed by Roman authorities in the early first century CE. His followers, the Christians, believed he was the son of God and had risen from the dead. At first Christianity was a small movement, and because Christians refused to worship the Roman gods or the emperor, they were at times persecuted, sometimes harshly. Despite this, the faith spread steadily through the cities of the empire over the following centuries.

The turning point came with the emperor Constantine. In 313 CE he issued the Edict of Milan, granting Christians freedom to worship, and he himself supported the religion. Constantine also founded a new capital in the east, the city of Constantinople (today's Istanbul), which would become enormously important later. By 380 CE, under the emperor Theodosius, Christianity was made the official religion of the Roman Empire. A faith once persecuted now had the backing of the state, a change that shaped the religious map of Europe for the next thousand years and beyond.

Crisis, division, and the fall of the West

The later Roman Empire faced mounting troubles: economic strain, plagues, civil wars over the throne, and growing pressure on its borders from various peoples the Romans called "barbarians," often migrating groups fleeing or seeking land. The empire had simply grown too large to govern as one unit. In 395 CE it was permanently divided into two halves for administration: a Western Roman Empire, centered on Italy, and an Eastern Roman Empire, centered on Constantinople.

The western half steadily weakened. Various Germanic peoples crossed the borders and settled inside the empire, and in 410 CE the city of Rome itself was sacked. Power drained from the imperial government to local military leaders. In 476 CE the last emperor in the west, a boy named Romulus Augustulus, was removed by a Germanic commander named Odoacer, and no new western emperor replaced him. Historians traditionally use this date to mark the fall of the Western Roman Empire.

Don't be confused: the "fall of Rome" in 476 CE means only the western half. The eastern half, ruled from Constantinople and later known as the Byzantine Empire, continued for almost another thousand years, until 1453. We pick up that story in the next chapter.

The lasting legacy

Greece and Rome left marks on the modern world that are easy to overlook because they are everywhere. From Greece came the ideas of democracy, citizenship, philosophy, scientific inquiry, and theater, along with styles of art and architecture, such as the columned temple, that are still copied on government buildings today. From Rome came a model of large-scale government and administration, a tradition of written law that underlies many modern legal systems, and engineering feats from roads to domes.

Perhaps the deepest legacy is language. Latin, the language of Rome, slowly evolved into the modern Romance languages, including Italian, Spanish, French, Portuguese, and Romanian, and it filled English with thousands of borrowed words. Latin also remained the language of learning, law, and the western church for over a thousand years. Together, the Greek and Roman worlds form what is often called classical antiquity, the shared foundation that later Europeans returned to again and again, as we will see in the chapters ahead.

When the Western Empire fell, western Europe entered a very different age, one of smaller kingdoms, a powerful church, and a slow rebuilding on Roman foundations. 👉 Continue to Medieval Europe (Medieval Europe).
