Hyolmo people

The Yolmo people are an indigenous people of the Eastern Himalayan Region. They refer to themselves as the "Yolmopa", and are native residents of the Helambu and Melamchi valleys (situated over 43.4 kilometres/27 miles and 44.1 kilometres/27.4 miles to the north of Kathmandu respectively) and the surrounding regions of northeastern Nepal. The combined population of Yolmos in these regions is close to 10,000. They also have sizeable communities in Bhutan and some territories within India, primarily Darjeeling and Sikkim. They are among the 59 indigenous groups officially recognized by the Government of Nepal as having a distinct cultural identity and are also listed as one of the 645 Scheduled Tribes officially recognised by the Constitution of India.

The Yolmo people speak the Yolmo language of the Kyirong-Kagate branch of the Sino-Tibetan language family. Accordingly, it has a high lexical similarity to Tibetan, although the two languages are not completely mutually intelligible. They are traditionally known to wear the chuba, which shares its name and many stylistic cues with traditional Tibetan attire. However, a large number of Yolmos native to Nepal, notably from Tarkeghyang, Milimchim Gaon, Shermathang, Dhana, Sarkathali among others, prefer to wear the daura-suruwal, the national attire of Nepal.
