Pratapa Gangaraju of the Silas had a daughter Singama. She was married to Khajjalabhanu alias Vinayaka deva, the founder of the kingdom of Gudari. On the dealth of Pratapa gangraja in A.D. 1443, the two kingdoms of Nandapur and Gudari near Gunupur were united under Vinayakadeva.Vinayakadeva is said to have been of the Ganga family of Cuttack. Pratapaganga as he had no sons, must have nominated his son-in-law Vinayakadeva, as his successor. According to the Jeypur Chronicle, Vinayakadeva was the 33rd descendant of Kanakasena of the Solar race. He was a general and feudatory of the king of Kashmir, left Kashmir for Benares, pleased Visvesvara by his penance and was directed by the God in a dream to go to the kingdom of the Silas of which he would become King. Vinayakadeva did accordingly, succeeded to the Jeypur throne and ruled from A.D. 1443 to 1476. His son Vijayachandra ruled from A.D. 1470 to 1510. His successor Bhairava dova (1510-1540), according to Ganga Vamsam or charitha vanquised prataparudraGujapati(l 496-1540) while he was going from south to north and extorted an elephant the idols of Kanakasurya and Vallabhanarayana from him. Padmanabhapur Yasovanta deva, the successor of Yasovanta deva. according to Gangavamsa charitra vanquished the Muslims who invaded Nandapura under the lead of Malika. Probably this Malik is identical with Buiramalk a man Malk who in A.D. 1599 defeated Sarvaraju and other big chieftains at the battle at Chintapalle and killed them. Inscriptions of the period at Simhachalam and Srikurmam attest the devastation of the Hindu Kingdoms in Vizagapatam and Ganjum districts carried on by the Muslim enemies—the occupation of Kotham etc. places by Ajvaravamingara ins A.D. 1609 by driving Bahubalesvra. Thus about the middle of the 15th century A.D. Silavamsa got merged into the Jaypur dynasty of which Nandapura continued to be the capital. Nandapurabhupati is included in the Briadamii of the Jaypur rajas and was first borne by Ramachandradeva II and their kingdom was known as Nandapurarajya.
