 The Dafala tribe was living in the hills to the north of present-day Lakhimpur district and Sonitpur district.They use to come down to the plains on marauding excursions when they would capture Assamese people and properties.The Dafalas were however kept in check by the grant of blackmail from the Ahom rulers and by permission to use the services of the Dafala-Bahatias who were formed into a penal colony settled along the foot of the Dafala hills.
