Kadambas of Hangal
The Kadambas of Hangal was a South Indian dynasty during the Late Classical period on the Indian subcontinent, which originated in the region of Hangal in Karnataka. Chatta Deva who reigned from 980–1031 CE founded the dynasty. He helped Western Chalukyas in the coup against the Rashtrakutas; re-established the Kadamba Dynasty mostly as a feudatory of Western Chalukyas, but his successors enjoyed considerable independence and were almost sovereign rulers of Goa and Konkan till 14th century CE. The successors of Chatta Deva occupied both Banavasi and Hangal and are known as Kadambas of Hangal. Uniting Banavasi and Hangal, distinguished himself against the Cholas and carved out a kingdom (which stretched, on this side, including Ratnagiri district, up to Kolhapur). He is referred to as having conquered Konkan. When the Chalukyas under their king, Jayasimha II made an advance on Dhar (capital of the Malavas) and defeated Bhoja, who was then the Paramara king, the part played by Chaltadev (Chatta Deva), the feudatory of the Chalukyas, was significant. During 1075-1116 Kirtivarma subdued the 7 Konkans. According to historian, George M. Moraes, Due to the struggle between the Hoysalas and the Yadavas, for supremacy, the Kadambas of Hangal under Kamdeva marched against the Konkan and compelled Vijayadatta (to transfer his allegiance to him). But during 1187 and 1188, immediately on his accession, Jayakesi III declared himself independent. Later Kadambas kept paying nominal allegiance to Yadavas and Hoysalas of Dorasamudra and thus maintained their independence. Different families of Kadambas ruled southern India, notable were Kadambas of Hangal, Kadambas of Goa, Kadambas of Halasi and Kadambas of Banavasi. Minor Kadamba Kingdoms
