Kozhikode was also successful in bringing the polity of Kolathunadu (Cannanore) under their control. During his expansions, the Samoothiri occupied Pantalayini Kollam as a preliminary advance to Kolathunadu. Kolathiri immediately sent ambassadors to submit to whatever terms Kozhikode might dictate. Kolathunadu transferred the regions already occupied to Kozhikode and certain Hindu temple rights. The stories about the origin of the Kadathanadu ruling family (Vatakara) are associated with battle of the Eradis with Polanadu. When the Samoothiri swarmed over Polanadu, he exiled a Polarthiri royal princess and she was welcomed in Kolathunadu (Cannanore) – one of the Samoothiri's rivals polities. After the marriage of a Kolathu prince with this princess the Kadathanadu ruling family was born. The name Kadathanadu refers to as the passing way between Kolathunadu and Kozhikode. Some land and Hindu temple rights were transferred to Kozhikode during a visit to Kollam by a ruler of the Kozhikode.
