This house's history is known through one record, the Kharepatan plates of Rattaraja issued in 1008. Rattaraja was the last ruler of this dynasty. The document is extremely important as it not only gives the genealogy of the ten ancestors of Rattaraja but also mentions their exploits. The founder, Sanaphulla, was vassal of the Rastrakuta emperor Krisna I who had established his power over Konkan by 765 and probably handed it to Sanaphulla. The Kharepatan plates declare that Sanaphulla obtained lordship over the territory between Sahya mountain and the sea through the favour of Krisnaraja.
