Ezhimala kingdom was succeeded by Mushika dynasty in the early medieval period, most possibly due to the migration of Tuluva Brahmins from Tulu Nadu. The Indian anthropologist Ayinapalli Aiyappan states that a powerful and warlike clan of the Bunt community of Tulu Nadu was called Kola Bari and the Kolathiri Raja of Kolathunadu was a descendant of this clan.[49] The Kolathunadu (Kannur) Kingdom at the peak of its power, reportedly extended from Netravati River (Mangalore) in the north to Korapuzha (Kozhikode) in the south with Arabian Sea on the west and Kodagu hills on the eastern boundary, also including the isolated islands of Lakshadweep in the Arabian Sea.[50]
