Research indicates that the Tamang people are a hybrid ethnic group with an estimated 59% genetic contribution from Tibetan and 41% from Nepalese ancestries. The Tamangs have been mentioned in various Nepalese and colonial historical records under a variety of names, such as
Bhote,
Bodh,
Lama,
Murmi and
Sain, some of which terms erroneously conflate the Tamangs with Uighurs. The Tibetans called them
Rongpa. Various Gorkha rulers led campaigns against the indigenous Tamangs. The Gorkha Vamsavali provides details of battles with the
Bhotyas of a variety of principalities between 1806 and 1862. In 1739, a ruler named
Ghale-Botya attacked
Nara Bhupal Shah as he was marching towards
Nuwakot, and Nara Bhupal Shah also fought several battles against Golma Ghale (Gyalpo). In 1762,
Prithvi Narayan Shah attacked the Tamangs in
Temal, the Tamang cultural heartland. Tamang oral history says that the local chief, Rinjen Dorje, was killed by the Gorkhas. Gorkhali forces had hidden their weapons in the sand on the
Sunkoshi riverbank in order to attack the Tamang forces. Afterwards, the Gorkhas washed their weapons in springs at
Dapcha Kuwapani, and this is why the modern-day Tamangs do not drink there. Similar stories appear in oral histories throughout the region. After the attack on the Tamang region, their traditional homeland area, known as
kipat to the Gorkhas, was granted to Gorkha generals or government officials who had pleased the king in some way, displacing the Tamangs from
kipat lands. Previously, Tamang landholdings had been divided up by clan. Tamangs also had various forced labor obligations, both in times of peace and war, that differed significantly from other regions of Nepal. One reason is the proximity of the Tamang homeland to the center of royal administration at Kathmandu. == Culture ==
