Kingdom of Kotte
The chieftains, who were known as Vanniars, would function like feudal lords in their territories. During much of the Transitional period where the island was politically unstable, depending on the situation at the time, the chieftains would owe their allegiance to one or the other kingdom. They offered military protection to those who came under their authority. Vanniars referred to a broad category of people who could have been appointees of the Sinhalese kings, who administered outlying districts or autonomous rulers of large, sparsely populated and undeveloped lands. The Vanniars in general paid tribute to the Kingdom of Kotte and later to the Kingdom of Kandy, apart from a few that were close to the Jaffna Kingdom.
