Pre-history
Anthropologists and historians claim that the fossil records show that people lived in Nepal around 30-40 thousand years ago. The first people of Limbuwan and Eastern Nepal could have been that batch of people too. The first people to live permanently and call Limbuwan their home were the Kirant people. These Mongoloid people are believed to have moved into Nepal from the east from Assam valley and beyond around 6-8 thousand years ago. They practiced shifting cultivation and moved with their domesticated pigs and other animals along the lower, warmer hills. The same people moved on to western Nepal and eventually conquered the Kathmandu valley to establish the first Kirant civilization of Nepalese history. They spoke the language of their Tibeto-Burman Ancestry and practiced animistic religion.
