Tetradrachm - Zoilos I Dikaios

Zoilos I ruled a shrinking Baktrian kingdom under sustained pressure from the Yuezhi migrations that had already displaced the Sakas southward and were steadily dismantling Greek hold on the region. His epithet Dikaios — "the Just" — appears on no earlier Baktrian royal coinage, suggesting a deliberate legitimizing claim, possibly in response to contested succession after Agathokles II or political fragmentation among the Indo-Greek dynasts competing for the same territories. By his reign, the eastern satrapies were effectively gone.
