Kos (Cos) is a Greek island in the south-east Aegean, part of the Dodecanese (ancient Sporades) group which prospered in antiquity due to its location on trade routes between Egypt, Syria, Cyprus, and Anatolia. Settled from the Bronze Age, the island was controlled by a long list of powers over the centuries. One of Kos' most famous sons was the celebrated physician Hippocrates, who created a school of medicine on the island in the 5th century BCE. Kos particularly flourished both politically and culturally in the 4th century BCE, after which it became a free city as part of the Roman Empire.
