People, Culture, and Languages. In Nepal, ethnical cultural groups are diverse and many of them have their own languages and customs. However they can be geographically categorized according to their habitats. The Sherpas who are of Tibeto-Burman stock mainly occupy the higher hills of eastern and central Nepal. The Solu Khumbu region, where the world's tallest peak Mt. Everest stands, is inhabited by Sherpas. Generally they are Buddhist but some follow the Bon, the pre-Buddhist religion of Tibet, and other religions. The Sherpas are famed for their valor and mountaineering skills and are professionally involved in many mountain expeditions. Today, Sherpas have joined other occupations as well, like business, administration and politics. A wide variety of ethnic groups occupy the mid-hills. The Kirats or Limbus and Rais inhabit the east. During the 7th century BC, they established a dynasty in the Kathmandu Valley and ruled it for 1,000 years. They are not originally Hindus or Buddhists but are ancestor worshippers. However, today, many embrace Hinduism. In the former days, they were warriors and skilled hunters. The Kirats speak Tibeto-Burman languages. Many serve in the British Army today and have earned a repulation as the brave Gurkhas. The population of the Kathmandu Valley consists mostly of Newars. They speak Nepalbhasa and practice Hinduism and Buddhism. Many families celebrate both Hindu and Buddhist festivals. Their culture also reflects tantrism and animism. Newars are accomplished in commerce and most enterprises in the heart of the Valley are run by them. Historically, they are well known for establishing the three artistically beautiful cities of Patan, Bhaktapur and Kathmandu. The inhabitants of the hill flanks surrounding Kathmandu Valley are mostly Tamangs, who make up one of the largest Tibeto-Burman ethnic groups in the Kingdom. In the Tibetan language, Tamang means "horse soldier" which gives us an idea about their past occupation. Today, they farm and work as semi-skilled and unskilled labourers. Tamangs practice Tibetan Lamaism or the Bon religion and speak their own language. The Magars live in the western and central hills of Nepal. They had their own kingdoms until the 18th century and were closely associated with the Hindu Indo-Aryans in the west. Much of their cultural practices have been influenced by Chhetris, and today it is difficult to make any difference in the housing, dressing and farming practices of the two. The Magars have been sought after by the British and Indian armies and a great number serve in the Gurkha regiments. Another ethnic group closely resembling the Magars in many aspects are the Gurungs. They also live in the western and central hills of the country although further to the east. Of Tibeto-Burman stock, the Gurungs have their own distinct language and practice shamanism. Many find employment in the British and Indian armies. The Khas are the Bahuns and Chhetris who formed their own kingdoms in the far-west. They are Hindus, and Nepali, which is the country's official language, was originally spoken by the Khas. Traditionally, the Bahuns were priests and are better educated than most ethnic groups. In fact, many occupy important government and educational posts in the kingdom today. The Chhetris have traditionally been known as warriors. Those living in the higher hills in the far western region lead hard lives because of lack of rain and farming is practiced in the river valleys and on the hill flanks. The Tharus are one of the original ethnic groups to inhabit the Terai. The Majhi, Danuwar, Rajbansi, Darai, Satar, and Dhimal also occupy the flat lands. The Tharus have their own unique religion and practice animism. Their culture is especially suited for the hot plains and they are actually Immune to malaria. They have Mongoloid features and speak their own language. There is much migration going on in the country now and the cultural definition of the people by area is difficult. Urban population is increasing by 7% each year and most cultures have intermingled.
