How did the 1816 Burman invasion of Assam affect the Naga region?

The 1816 invasion of Assam by Burman forces from Myanmar resulted in a period of oppressive rule over the region that lasted from 1819 until the establishment of British authority in 1826. While the invasion primarily targeted the neighboring Ahom kingdom, it occurred during a time when the Naga region lacked a formal written history, and the subsequent instability and eventual transition to British administration significantly altered the social landscape of the Naga tribes.1

The arrival of the British, which followed the end of the Burman occupation, eventually brought an end to traditional practices such as headhunting and intervillage raids, establishing a period of relative peace across most of the Naga territory by 1892.1
