Cotys III (VII) was the son of Sadalas II and Polemokrateia. After the
murder of his father his mother surrendered the family treasure to M.
Iunius Brutus to save him. Cotys was raised in Cyzicus and was
installed as an astaean-odrysian king about 28 BC. The sapaean
Rhoemetalces I was his brother-in-law and was later appointed guardian
of Cotys's son Rhaescuporis II. Cotys III (VII) was probably killed
during the war activities of the roman governor of Macedonia M. Primus
in Thrace about 22 BC [Pauly].
No coins were issued
in the name of Cotys III (VII)
