Vashishtiputra Satakarni

Vashishtiputra Sātakarni was in great conflict with the Scythian Western Kshatrapas in the West, but he eventually married the daughter of Rudradaman I of the Western Kshatrapas dynasty, in order to forge an alliance. The inscription relating the marriage between Rudradaman I's daughter and Vashishtiputra Satakarni appears in a cave at Kanheri:

"Of the queen ... of the illustrious Vashishtiputra Satakarni, descended from the race of Karddamaka kings, (and) daughter of the Mahakshatrapa Ru(dra)....... .........of the confidential minister Sateraka, a water-cistern, the meritorious gift.

— Kanheri inscription of Rudradaman I's daughter".

Later, however, Vashishtiputra Sātakarni was defeated by his father-in-law in battle, with serious effect on Sātavāhana power and prestige:

"Rudradaman (...) who obtained good report because he, in spite of having twice in fair fight completely defeated Satakarni, the lord of Dakshinapatha, on account of the nearness of their connection did not destroy him."
