Were the Mauryans vassals of the Seleucids?

Was that woman Selucus' daughter? Mentioned earlier also, Selucus was not at all Interested in Indian territories. He perhaps had his eyes on Greece.
What little we know about the treaty between Seleucus and Chandragupta is mention of three clauses, although there may well have been others. One of the clauses concerns Seleucus relinquished sovereignty of some provinces: the Indus valley, the Paropamisadai, and Arachosia. There was also a clause concerning Chandragupta`s delivery to Seleucus of 500 war elephants; and the other clause governed intermarriage. There is actually no evidence, as some have suggested, that one of the two rulers handed over a daughter as a wife for the other. The clause governing intermarriage may well have concerned marriage between the subjects of the two rulers.

The Bluff

It was most likely other way around as giving up your daughter to your enemy is considered most humiliating thing in India as we see from Mughal-Rajput relationships.

Selucids invaded India for more lands, Mauryans defeated them, took daughter of king to further humiliate him and 1/3 of his Empire.

And made his now father in law his autonomous vassal and allowed him to go home.
Nothing whatsoever in the sources requires us to believe Seleukos gave up a daughter in this settlement. That is simply your own inference. The Greek of Strabo (ἐπιγαμίαν) simply means a right of intermarriage between two states. Appian describes this as the pair agreeing a connection by marriage (κῆδος συνέθετο); it does not explain the detail of that connection. Chandragupta might just as easily have married a Macedonian. It may even not have involved the two kings but one of their senior staff. To say Seleukos offered his daughter based on that is pure guesswork.

Why must the intermarriage be seen only from an Indian viewpoint? Macedonian monarchs married off relatives for political gain at the drop of a hat. It did not require that the monarch in question had been defeated. Far from it.

But for some of us, Chandragupta marrying the daughter of Seleukos is a victory greater than getting the control of some erstwhile Greek provinces, therefore, the story continues. :D
