The ruler of Tanur was one of the earliest rajas on the Malabar Coast to acknowledge the suzerainty of the zamorin of Calicut.
Princes from the Tanur royal family, along with princes and other "Kshatriya" royal families such as Beypore (Parappanad), Kurumburanad and Cranganore, were eligible to marry princesses from the Calicut royal family.
