Assam-Mizoram border dispute

Date: 28 July 2021 Tags: Miscellaneous


A violent clash took place near the border between Mizoram and Assam that led to death of five Assam policemen.



This incident is not new. Last year residents of Assam and Mizoram had clashed, leading to injuries and loss of property.



  • The dispute with the Mizos started after British expansion of tea gardens into the traditional areas of Mizos.

  • The British demarcated a boundary between the Lushai hills (control of Mizos) and Cachar plains (British territory) in 1875, in consultation with Mizo chiefs.

  • When a new boundary with Manipur was drawn near the tri-junction in 1933, Mizos did not accept it citing non-consultation.

  • The issue remained even after independent states such as Manipur, Mizoram, Assam and Nagaland were carved out in the region.


Flare up of issue

  • The agreement had said that a no-man’s land was to be set up at the border. Several Mizo groups built a wooden rest house, which was demolished by Assam police.

  • Clashes broke up again last year when Assam made construction on a land claimed by Mizoram.


Assam’s stand

The contested land belongs to Assam and has been cultivated by residents of Mizoram. This has affected ownership rights of the state.


Mizoram’s stand

  • Residents of Mizoram claim that the illegal migrants from Bangladesh were responsible for attacking Mizo residents and destroying their property.

  • They say that the boundary has to be demarcated based on 1875 agreement. However, Assam follows the 1933 demarcation, which is the root of all problems.
