I want to know the answer to the following question:
When was Diodotus II overthrown?
All the background I'm provided with is that "While victorious in the field, it seems Antiochus came to realise that there were advantages in the status quo (perhaps sensing that Bactria could not be governed from Syria), and married one of his daughters to Euthydemus's son, thus legitimising the Greco-Bactria dynasty.". Is that enough to answer the question?
Answer: no
