Separatist movements also exist in two other former princely states located in Northeast India— Tripura and Manipur, though insurgency in Tripura has been crushed and Manipur has also been peaceful . However, These separatist movements are generally treated by scholars as being part of the broader problem of insurgencies in North-east India, rather being a result of specific problems in integrating the princely states into India, as the Kashmir problem is and, in particular, to reflect the failure of the Government of India to adequately address the aspirations of tribal groups in the Northeast, or to tackle the tensions arising from the immigration of people from other parts of India to the north-eastern areas.
