In many recent sources, Chalukyas or famously Solankis are considered to be Agnivanshis, born from the Agnikund at Abu, by Sage Vashishtha. These thoughts are just following the famous Prithiviraj Raso by Chandbardai. But this fact is purely fiction. There is proof to believe this. Inscriptions of ancient Chalukya kings trace back their origin to Arjun, one of the famous Pandavas. So, they are considered to be purely descendents of the lunar race or Chandravanshis.
Arjun was 41th descendent of Lord Visnhu. His 7th descendent was Udayan. Starting from Udayan, 56 kings ruled near the area of Soram. Thus, "nikas" of Chalukyas is considered to be "Soram Ghat".
After that, Chalukya was born, from which the clan took its name. Some sources claim that he took this name after worshipping Lord Vishnu on Chalukya mountain. He was married to Rashtrakuta princess, from which manvya was born. In the lineage of Chalukya, Vijayaditya was born who moved to southern India to form new kingdom.
Vijayaditya fought with Trilochan Pallav and died. His queen, who was about to birth a child, took shelter in at Vishnubhatt Somayaji in Madivemu village, where Vishnuvardhan was born.
Vishnuvardhan worshipped Goddess Gauri, who gave him with the royal insignia of the Chalukyas.
Royal insignias - Silver Chattra, Panchamahashabdh Shank, Palidhwaj (Flag), Prati Dhakka (Royal drum), Sign of Varah (which remain the their sign forever), Morchaal, MakarToran, Royal Seat (Sinhasan), Sword of gold.
Vishnuvardhan defeated Kadambvanshi Kings and annexed their 7500 villages. His descendents ruled from there, but they were unable to control the kingdom and thus readily declined.
After 15 generations of Vishnuvardhan, Jaysingh was born. He defeated Rashtrakuta King Krishna and restablished the honour of Chalukyan Empire.His capital was Badami and his descendents were known as Chalukyas of Badami.
His grandson was Pulkeshi-I(553-566 A.D).
