Hey guys while surfing i found this info.
Bheemdeo, the ruler of Gujarat, had killed Prithvi Raj's father Someshwar in battle. Prithvi Raj was, therefore, itching to avenge his father's death. An opportunity presented itself when Bheemdeo asked for the hand in marriage of Ichchhini Kumari, the daughter of Jait Parmar, the ruler of Abu. When his suit was rejected, he threatened invasion. Jait Parmar sought Prithvi Raj's help. Prithvi Raj was only too willing to oblige because he had an old score to settle with Bheemdeo. In the battle fought on the banks of the Sabarmati river within Bheemdeo's territory, Prithvi Raj inflicted a crushing defeat on the former. A grateful Jait Parmar then gave his daughter Ichchhini Kumari in marriage to the proud victor Prithvi Raj.

Sagars haven't shown Bheemdev's defeat like this, so I think they are not showing Prithvi marring Ichhini or Indravati (I suppose) only Sanyogita for him in the serial.😳😆
