Sitalces (
Ancient Greek S?t?????, reigned 431-424 BC) was one of the great kings of the
Thracian Odrysian state. He was the son of
Teres, and on the sudden death of his father in 431 BC succeeded to the throne. Sitalces enlarged his kingdom by successful wars, and it soon comprised the whole territory from
Abdera in the south to the mouths of the
Danube in the north, and from
Black Sea in the east to the sources of the
Struma in the west.
At the commencement of the Peloponnesian war Sitalces entered into alliance with the Athenians, and in 429 BC he invaded Macedon (then ruled by Perdiccas II) with a vast army that included 150,000 warriors from independent Thracian tribes (such as the Dii) and Paeonian tribes (Agrianes, Laeaeans). He was obliged to retire through failure of provisions.
Sitalces was killed in 424 by the Thracian Triballi. He was succeeded on the Odrysian throne by Seuthes.
