In 1873 when the Inner Line Permit was introduced in Naga hills it was a dangerous place for outsiders including Nagas themselves. Naga tribes were very hostile to outsiders including Nagas of other tribes. Head hunting was a practice where the tribes would hunt the outsiders entering their territories and hang their victims cut heads outside their houses to show their acts of bravery. The Inner Line Permit kept record of who entered Naga Hills and where they went and when they returned to ensure that they are not killed by head hunters thinking them to be intruders in their Naga territories. But today 60 years after Independence Nagas have become peaceful people and live harmoniously with each others tribes. The Inner Line Permit is today continuing so that the illegal entry of Non-Indians could be stopped from entering Nagaland and other hill states of North East on Indian International border.
