the foundations of Western civilization. The playwrights Aeschylus, Sophocles and Euripides flourished in Athens during this time, as did the historians Herodotus and Thucydides, the physician Hippocrates, and the philosopher Socrates. Guided by Pericles, who promoted the arts and fostered democracy, Athens embarked on an ambitious building program that saw the construction of the Acropolis of Athens (including the Parthenon), as well as empire-building via the Delian League.

The resulting tensions brought about the Peloponnesian War (431–404 BC), in which Athens was defeated by its rival Sparta.
By the end of Late Antiquity, the city experienced decline followed by recovery in the second half of the Middle Byzantine Period, in the 9th to 10th centuries AD, and was relatively prosperous during the Crusades, benefiting from Italian trade. In 1458 it was conquered by the Ottoman Empire and entered a long period of decline.
Following the Greek War of Independence, Athens was chosen as the capital of the newly independent Greek state in 1834, largely due to historical and sentimental reasons. At the time it was a town of modest size built around the foot of the Acropolis. The first King of Greece, Otto of Bavaria, commissioned the architects Stamatios Kleanthis and Gustav Schaubert to design a modern city plan fit for the capital of a state.
