Odrysæ

The most powerful people in Thrace, dwelt, according to Hero dot us, on both sides of the river Artiscus, a tributary of the Hebrus, but also spread farther west over the whole plain of the Hebrus. Their king Teres retained his independence of the Persians 508 B.C. Sitalces, his son, enlarged his dominions, and in 429 aided the A then i ans against Perdiccas II. of Macedon with an army of 150,000 men. Sitalces was killed in battle with the Triballi, 424. Cotys, another king (382-353), disputed the po e ion of the Thracian Cher sones us with Athens; after nine or ten years’ warfare, Philip II. of Macedon reduced the Odrysæ to tributaries.
