Among the most powerful city-states in ancient Greece, Athens was the first, and Sparta was the second. The so-called city-state is a country with cities as the center and surrounding towns and villages. Sparta is located in the southern part of the Greek peninsula in the Laconian Plain.

Laconia is surrounded by mountains on three sides, with a small plain in between. "Sparta" originally meant "a cultivable plain". Around the 11th century B.C., a group of Greek tribes called the Dorians invaded Laconia, destroying the original city-state and settling in what became the city of Sparta of the Dorians - but it had neither walls nor decent streets.

The Spartans are the Dorians who came here.

Spartacus (historical figure).

Spartacus was a Thracian from the northeastern Balkans, and when the Romans invaded northern Greece, he was captured and sold as a gladiator slave to a gladiator school in Capua. He encouraged his companions to seize arms and flee to Vesuvius to start an uprising. The revolt quickly grew from more than 70 gladiators to more than 100,000 men, and defeated the Roman army several times.

In 72 BCE, Spartacus led his army along the Adri coast through Italy, crushing the army of the governor of Cassius at the Battle of Mordina before moving south. The Roman Senate declared a state of emergency and ordered Crassus to lead a large army to suppress it. In the autumn of that year, the rebels suffered heavy losses at the Battle of Brutia and were forced to cross the sea to Greece in the spring of 71 BC by attempting to raid the southern Italian port of Brindisi.

The Roman army was surrounded on all sides and finally suppressed the revolt in the decisive battle of Apulia, killing Spartacus and fighting for ten years in many parts of Italy.
