The political power balance shifted as Samoothiri killed Porlathiri of Polanad by treachery, occupied Kozhikkode, developed the town as port, grew rich by a flourishing trade, and diverted most of the funds to developing a huge army. Samoothiri had ambitions to be the absolute emperor of Kerala. The funds from Kozhikkode port provided the crucial advantage in his wars. Parappanad and Vettathunad soon had to submit to the power of the Samoothiri and became his feudatories one by one.
 

Panniyur - Chovvaram fight : The Brahmins of Panniyur made an idol of Lord Siva in an awful disposition, presiding over death and disease. This was intended to be an insult on Chovvaram. The Namboodiris of Chovvaram stole the controversial idol from the shrine built by Panniyur group. The leader of Panniyur group, Tirumanasseri Namboodiri, who ruled Gowardhanapuram just south of Thirunavaya, with the help of his three thousand Nair soldiers, attacked and burned Chovvaram. The Chovvaram group appealed to the Walluvanad Rajas for help. But Thirumanasseri Namboothiri did not accept the mediation of the Rakshapurusha in this matter. This resulted in Valluvakkonathiri and Perumpadappu Raja declaring war simultaneously against Thirumanassery Namboothiri, who appealed to Samoothiri, a rising power then. He promised Samoothiri full support in capturing Ponnani from Vellaattiri. Samoothiri, looking for such an opportunity, gladly accepted the offer.
