The Parthians drive back the last Seleucid…

The Parthians drive back the last Seleucid counterattack in 129 BCE, a turning point in the history of the eastern Mediterranean: Greco-Macedonian domination receives a decisive blow, which it will survive for only forty-six more years.

The loss of their king in the battle of Ecbatana together with so much territory sends the already enfeebled Seleucid empire into a decline from which it can never recover.

The Empire becomes a rump state that consists of little more than Antioch and the surrounding lands.

The only reason the Seleucid Empire continues to exist is because the Parthians see it as a useful buffer against the Roman Empire.

Antiochus leaves five children by his queen.

Syria lapses into civil war, with all hopes of empire gone.

Demetrius II returns to Syria after his release form captivity, but during his second reign, he controls only part of the kingdom, and is assassinated about four years later.

Neighboring states begin to gnaw constantly at the edges of the weak and divided kingdom.
