Voted for Colkhis but there must me Caucasian Iberia instead. C.I. was a kingdom then. And Colchis partialy was a province of Pontus and partialy of Caucasian Iberia. Pontus's part of Colchis then to become Rome province, and only in 200-300 years Colkhis will establish a new independent Kingdom - Lazika or Egrisi
