Sigh. Trolling aside.
Take a look at this map:
Leave aside Jambavati and Yamuna whom Krishna married as rescues from Balram.
The rest were all from kingdoms which could ally with Dwaraka in case of an external attack or a dowry girl like Satyabhama,
Avanti/Vidarbh to the south, Kosala to the east, Madra/Gandhar/Kekaya to the north.
Krishna was an extremely political animal. Even his so-called romances were all politics. No Lakshmi avatar, no love letter, nothing of the sort. Rukmini-vivah is actually stated to be rakshasa vivah. ie, forceful marriage, not elopement. Krishna did it because politics.
