A Mahadeva temple constructed during his rule finds mention in a Greek writing of the period. According to the Gudnapur inscription, lesser rulers such as the Punnatas, the Alupas, the Kongalvas and the Pandyas of Uchangi were dealt with successfully. The crux of the kingdom essentially consisted of significant areas of the deccan including large parts of modern Karnataka. King Ravivarma of the Banavasi branch killed king Vishnuvarma of the Triparvata branch according to Moraes and successfully dealt with a rebelling successors of Shiva Mandhatri at Ucchangi. The Pallava king Chandadanda (another name for Pallava king Santivarman) also met the same fate according to Sathianathaier. Ravivarma left two of his brothers, Bhanuvarma and Shivaratha to govern from Halasi and Ucchangi. Decline  After Ravivarma's death, he was succeeded by his peaceful son Harivarma in c. 519 according to the Sangolli inscription. According to the Bannahalli plates, Harivarma was killed by a resurgent Krishnavarma II (son of Simhavarma) of the Triparvata branch around c.530 when he raided Banavasi, thus uniting the two branches of the kingdom. Around c.540 the Chalukyas who were vassals of the Kadambas and governed from Badami conquered the entire kingdom. The Kadambas thereafter became vassals of the Badami Chalukyas. In later centuries, the family fragmented into numerous minor branches and ruled from Goa, Halasi, Hangal, Vainad, Belur, Bankapura, Bandalike, Chandavar and Jayantipura (in Odisha). That the Kadambas of Banavasi were a prosperous kingdom is attested to by the famous Aihole inscription of the Chalukyas which describes Banavasi in these terms:  The Kadamba kings, like their predecessors the Shatavanahas, called themselves "Dharmamaharajas" ("lit", "Virtuous kings") and followed them closely in their administrative procedures. The kings were well read and some were even scholars and men of letters. Inscriptions describe the founding king Mayurasharma as "Vedangavaidya Sharada" ("master of the Vedas"), Vishnuvarma was known for his proficiency in grammar and logic, and Simhavarma was called "skilled in the art of learning".
