Many historians divide up the history of Ancient Greece into three periods. They are the following:

Archaic Period

This period occurred from the start of Greek civilization in 800 BC to the introduction of Democracy in 508 BC. It also includes the beginning of the Olympic Games and the writing of the Odyssey and the Iliad by Homer.

Classical Period

The classical period is the time that comes into most people’s minds when they think about Ancient Greece. During this period, Athens was governed by democracy, and great philosophers such as Plato and Socrates arose. In addition to that, the wars between Sparta and Athens happened during this time. The classical period ended with the rise and the death of Alexander the Great in 323 BC.

Hellenistic Period

This period lasted from the death of Alexander the Great until 31 BC, when Rome defeated Egypt at the Battle of Actium. The term “Hellenistic” came from the Greek word “Hellas,” which is the original word for “Greece.” [1]

Important Cities in Ancient Greece

Ancient Greece was a civilization that strived to conquer the world. It has contributed largely to human culture, which gave us science, philosophy, architecture, sports, and democracy. The city-states in Ancient Greece were spread across much of the world, from Europe to the Middle East to Africa to Asia. If you want to learn more about these, here are the important cities in Ancient Greece.


a view of the Acropolis of Athens in Greece

Based on legends, Athens was seized by the goddess Athena from King Poseidon due to an epic conflict. First settled in 3000 BC, Athens was located on the Acropolis rock. It became a major center of Mycenaean civilization by 1400 BC, wherein the Acropolis was a large Mycenaean fortress.

The power of Athens lay in its trade and naval dominion, which was demanded by the search for provisions warranted by its unproductive soil. During the golden age of Greece in the 5th century BC, Athens was the center of classical civilization, leading democracy.


aerial view of Sparta, Peloponnese

In Ancient Greece, Sparta was a large polis and the main rival to Athens. The main strength of Sparta lay in its military power. Their army was small, and every adult male has deemed a soldier and handled a slave-run farm. It started as a small polis that had five villages. Later on, it grew by seizing neighboring villages and states. It eventually consumed most of the Peloponnese and enslaved their inhabitants.

Sparta was massively powerful by 650 BC as it controlled a vast expanse. People there were kept in check by a warrior class. It could only be controlled through military alliances formed between other prime Greek city-states, such as Athens, Argos, Corinth, and Thebes. However, in 362 BC, during the Battle of Mantinea, Sparta eventually fell to Thebes.


the asclepion of Pergamon

Pergamon was a powerful Hellenistic colony that exercised dominion over large paths of Asia Minor in the 3rd and 2nd centuries BC. It has a library that contains the most impressive collection of scrolls, so much that the Egyptians imposed a restriction in Pergamon as they feared competition for Alexandra’s collection of scrolls. But Pergamon, in turn, made “paper” using animal skin.

This city was an important sanctuary that was dedicated to Zeus. It was also home to the Panhellenic Games, which is the Olympic Games today. The city is based at the foot of Mount Cronus on the right bank of River Alpheus. Its Temple of Zeus contained a statue of Zeus that was 12 meters high. It was considered to be a Wonder of the Ancient World.


Thebes was a city built at the base of the Teumessus mountain. It was 48 kilometers northwest of Athens. It also grew to be the largest city in that region. It has the famous seven gates whose names were not agreed upon by historians of old. For example, Euripides refers to them as Neista, Pretida, Ogigia, Homoloid, Crenea, Electra, and the unnamed Seventh Gate. According to modern historians, the people of Thebes were Pelasgians and not of Phoenician origin. Some also believed that Thebes was a colony on Crete, and the only contribution of the Phoenicians was the alphabet.


the ruins of Miletus

This was one of the true ancient cities. It was made with iron granite from Mount Olympus. Miletus was a premier fortified city on the western coast of Anatolia, near the mouth of the Meander River. It used to be the most flourishing among the twelve cities of the Ionian confederation. However, it was looted and burned many times. During the 6th and 5th centuries, Miletus was at the peak of its glory. Some of the famous inhabitants of the city were philosophers Anaximander, Anaximenes, and Thales.

This was a premier Greek city in Sicily that was built in 734 BC. The city was the birthplace of Archimedes, the physicist. Sicily was controlled mostly by Syracuse in 382 BC. It had also seized Carthage in the far west along with several Greek cities of Italy. During that time, it was the most powerful Greek polis, and its tyrant Dionysius I was the most powerful man in Greece.


This city was the capital of Thrace. It was built in 667 BC at the entrance to the Bosphorus Strait. However, the city of Byzantium crumbled under the control of Rome.


The city of Cyrene was built by Greeks who came from Santorini under the influence of the Oracle of Delphi. It was founded in the valley of Djebel Akhdar. Cyrene became the most important of the five Greek colonies in the region, which amped up trade relations with all the cities in Greece.


Argos was a Greek city in the Peloponnese region, and it was founded in 2000 BC. Based on legends, Inacus, along with his descendants, ruled the city for nine generations.


ruins of Celsus library in Ephesus

Ephesus was included in the twelve Ionian cities on the shores of the Aegean Sea. The city was built in the 11th century BC by Athenian colonists under the leadership of the son of King Codros. It was an important cultural, religious, and commercial center.

Alexander the Great, his son, set out to overpower the world, which started in the Hellenistic period of Greek history. An odd fact about the city was that its inhabitants had to hunt a boar to be able to claim a set at the banquet table.


The first Greek to cross the Pillars of Hercules was the Colaeus of Samos. The city of Samos was economically rich from 538 to 522 BC. It ruled over the archipelago and became a strong maritime city-state in the Aegean Sea. The city was home to the architect and inventor Theodore, philosopher Pythagoras and Epicurus, mathematician and astronomer Aristarchus, and ruler Polycrates.


According to legends, Andremon, husband of Gorge, son of Oenaeus, and father of Toas, was the one who founded the city of Colophon. It was an Ionian city in Asia Minor that was built on the banks of the River Ales. It was close to the coast, which made it ideal for a rich maritime culture.


the Temple of Aphaia on Aegina in Greece

By the Middle Helladic period from 2000 to 1600 BC, it had moved to the top of the Acropolis since the plain had flooded.

Most Significant Battles in Greek History

There were many battles fought by the Ancient Greeks throughout history. But among those, these three are the most significant of their clashes:

Most Significant Battles of Ancient Greeks

The Peloponnesian War

This war saw Sparta and Athens squaring up for a clash that changed history. It occurred from 460 to 404 BC. It can be divided into three stages. The first one was a 10-year series of inconclusive clashes. The second one was a six-year truce. However, there was nothing inconclusive about the third phase. In 405 BC, the Spartan general Lysander won over the Athenian fleet at Aegospotami, which led to the surrender of Athens. With this, Sparta became the undisputed top dog in the region.

The Battle of Marathon

In 490 BC, when Athenian forces attacked a huge Persian invading army at Marathon, the stakes couldn’t have been higher. Victory would give a huge shot in the arm for the nascent Athenian democracy, but losing would see it engulfed by the Persian empire. Fortunately, Miltiades, the commander of Athenians, executed a brilliant battle plan. They have drawn the best Persian troops into his army center before surrounding and attacking them.

The Macedonian Wars

The Macedonian Wars include four battles that were fought between the Greek kingdom of Macedonia and Rome during the third and second centuries BC. In the first war, Macedonia under King Philip V defeated Rome. However, they suffered defeats in the second and third wars. The fourth war saw Macedonia turn into a Roman province in the second century BC. Rome stayed the dominant force in the Mediterranean for generations.[4]

Ancient Greeks in Numbers

In this part, we are giving you the different statistics and data about the Ancient Greeks, including their population, slavery, and battles.

Ancient Greece Population

Ancient Greece Population

The geographical definition of the Greek area transformed over time. Today, Macedonia is considered part of the Greek world. However, back in the classical period, it was a separate kingdom that used the Doric dialect and later on changed to the Attic dialect.

Based on estimates, the Greek-speaking population in the hinterland and islands of the Aegean Sea in the 5th century varied from 800,000 inhabitants to more than 3,000,000. In the 4th century, Athens had 60,000 natives. If you add the slaves and the foreign population, the number will rise to 350,000 to 500,000 inhabitants, wherein 160,000 of them lived in the city and the rest in the suburbs.

The population of the whole Greek territory, which includes Greece, Greek colonies in Sicily, the coasts of western Asia Minor, and the Black Sea, during the 4th century BC was about 8,000,000 to 10,000,000 inhabitants based on the latest estimates. It is about 12 times greater than in the 8th century BC, which was 700,000 inhabitants.[5]

Number of Slaves in Ancient Greece

Slavery in Ancient Greece

80,000 – 100,000 The estimated number of slaves in Ancient Greece.

There is clearly not a formal register of the number of slaves in Ancient Greece. But a historian named Paul Catledge estimated the numbers. He compared it from modern slave societies such as Brazil, the Caribbean, and the Antebellum South and expects the number to be around 80,000 to 100,000. With a total population of 2,500,000 between 450 and 320 BC, it means that one in four of the people in Athens were slaves.[6]

Ancient Greeks in Wars

The Ancient Greeks fought a lot of wars, and that is a fact. However, we cannot determine the exact number of battles they have been into. One of the most famous battles in history was the Battle of Thermopylae, which was told in the 2006 film titled 300. Based on the film, back in 480 BC, a handful of Spartans fought the armies of Persia for three days. Do you think this was just a one-sided legend?

The Battle of Thermopylae

Well, based on historians, it is true that there were only 300 Spartan soldiers at the Battle of Thermopylae. However, they were not alone. It’s because the Spartans had formed an alliance with other Greek states. Based on estimates, it is thought that the number of ancient Greeks was around 7,000. However, the size of the Persian army is disputed. According to 5th century Herodotus, there were more than 2 million, but it was more likely to be about 100,000 to 300,000. This means that the Greeks were still against overwhelming odds.

Since Persia had a huge army, they were intent on invading and conquering Greece. However, the Spartans were brutal, and they never surrendered. Much of the Greek armies were wiped out, but it allowed the bulk of the army to retreat and regroup. With this, the invasion of Persia ended in failure as the Greeks won at the Battles of Salamis and Plataea.[7]
