This period is defined by the rise of democratic Athens and the expansion of Macedonia. It also saw the intense First and Second Peloponnesian Wars. During this time, Greek culture reached a peak of flourishing. This era left a massive footprint on Western civilization. It provided the foundation for much of our modern math, science, and philosophy. These ideas later moved into and heavily influenced the Roman Empire.

In Athens, political life changed forever due to the reforms of Cleisthenes in 508 BC. After the fall of the tyrant Hippias, Cleisthenes established isonomic institutions. This term refers to equal rights for all citizens, though only men were considered citizens. He also introduced isegoric, which means equal freedom of speech. The city was organized into about 130 demes, or local civic units. To prevent local interests from dominating, the territory was divided into thirty trittyes. These were split into coastal, urban, and rural groups. A tribe was formed by selecting one trittye from each group at random. This ensured every tribe represented the whole region.

The Persian Wars were a series of major conflicts between Greece and the Persian Empire. The tension began with the Ionian Revolt in 499 BC. In 490 BC, the Persians attempted to punish the Greeks at the Battle of Marathon. A Greek army of 9,000 Athenian hoplites and 1,000 Plataeans defeated them. Later, in 480 BC, Xerxes I led a massive force of 300,000 men and 1,207 ships.

The Spartan king Leonidas I famously held the pass at Thermopylae. Although the Persians burned Athens, the Athenian navy won a decisive victory at the Battle of Salamis. The final major land battle occurred at Plataea in 479 BC. After this defeat, the Persians withdrew and never attempted another invasion.

Following the Persian threat, Greek city-states formed powerful coalitions. Athens led the Delian League, which was named after the sacred island of Delos. The league's treasury was kept on Delos to help liberate Greek cities. However, Athens eventually used this league to establish its own hegemony, or leadership, over the Aegean. In response, Sparta led the Peloponnesian League. This was not a true league of equals, but rather an instrument of Spartan policy. It was designed to ensure Spartan security and dominance over the Peloponnesian peninsula.

The rivalry between these two leagues led to the Peloponnesian War in 431 BC. This was a massive struggle between the Athenian-led Delian League and the Spartan-led Peloponnesian League.

The conflict was exhausting for all involved. After a period of fighting, a brief peace was reached, but the war eventually resumed. The war ended in 404 BC when Athens was decisively defeated. This defeat left the Greek world marked by internal unrest and weakened power structures.

Despite the wars, the period saw incredible architectural and artistic achievements. The Greeks developed complex styles in sculpture and theatre. They built massive temples, such as the Parthenon on the Acropolis.

These structures used precise mathematical principles. The era of Classical Greece eventually transitioned into the Hellenistic period. This change was triggered by the rise of Macedonia. King Philip II unified most of the Greek world against the Persian Empire.

The era reached its conclusion through the conquests of Alexander the Great. Alexander was the son of Philip II. He led his armies to conquer the Persian Empire in just 13 years. This massive expansion changed the map of the ancient world. His reign marked the end of the classical era and the start of a new age. The legacy of this period remains visible in our laws, arts, and scientific thought today.
