Demography of Longleng District
The population of the district is mainly tribe based. The Phom Nagas inhibit Longleng who are exceptionally good with pottery, spinning and bamboo work. Traditionally, the Phom Nagas have forayed into the occupation of agriculture. The origins of the Phoms can hardly be ascertained, but from oral tradition it can be deduced that this tribal group even emerged from the similar source as like the Ao Nagas. Phom Nagas have mostly converted into Christianity and thus have modernized to a large extent. However, during festivals they can still be found wearing Vihe-Ashak or Nempong-Ashak, which are shawls wrapped around the body. The Monyu Festival that is celebrated to herald the summers is celebrated with much pomp and fanfare. It also bids farewell to the winters. It is a six-day affair held during the month of April, right after sowing. Monyu is one of the main festivals of the Phom Nagas.
