The assassination of a minister of Calicut by the chief minister of Valluvanadu while visiting Venkatakkotta in Valluvanadu sparked the battle, which dragged on for almost a decade. At last the Valluvanadu minister was captured by Zamorin's warriors and executed at Padapparambu, and his province (Ten Kalams, including Kottakkal and Panthalur) were occupied by the Zamorin. The Kizhakke Kovilakam Munalappadu, who took a leading part in this campaign, received half of the newly captured province from Zamorin as a gift.
