The family feud between the elder and younger branches of the ruling family of Kochi was exploited by the Zamorin of Calicut. The intervention was initiated as Calicut’s help was sought against the ruling younger branch. The rulers of Kodungallur, Idappalli, Airur, Sarkkara, Patinjattedam [Thrissur] and Chittur supported or joined Calicut forces in this occupation of Kochi.
