Trausi
The Trausi or Thrausi were a Thracian tribe who inhabited the southwestern region of the Rhodopes.
Herodotus writes of the Trausi:
The ethnonym Trausi may derive from Trauos, the name of a river. An etymology found in Duridanov's paper derives the tribe name from an adjective, meaning "The Crumblers" or "The Shatterers", deriving from PIE *dhreu-, 'to crumble, grind'. The Ancient Greek verb thrauô, 'to break in pieces, shatter', would be a cognate.
