Sherpa people
The Sherpa are one of the Tibetan ethnic groups native to the most mountainous regions of Nepal, Tingri County in the Tibet Autonomous Region and the Himalayas. The term "sherpa" or "sherwa" derives from the Sherpa language words ("east") and ("people"), which refer to their geographical origin of eastern Tibet. Most Sherpa people live in the eastern regions of Nepal and Tingri County however, some live farther west in the Rolwaling Valley , Bigu and in the Helambu region north of Kathmandu, Nepal. Sherpas establish gompas where they practice their religious traditions. Tengboche was the first celibate monastery in  Solu-Khumbu. Sherpa people also live in Tingri County, Bhutan, and the Indian states of Sikkim and the northern portion of West Bengal, specifically the district of Darjeeling. The Sherpa language belongs to the south branch of the Tibeto-Burman languages, mixed with Eastern Tibet (Khamba) and central Tibetan dialects. However, this language is separate from Lhasa Tibetan and unintelligible to Lhasa speakers. The number of Sherpas migrating to Western countries has significantly increased in recent years, especially to the United States. New York City has the largest Sherpa community in the United States, with a population of approximately 16,000 . The 2011 Nepal census recorded 512,946 Sherpas within its borders. Members of the Sherpa population are known for their skills in mountaineering as a livelihood. History. Tibet to Solukhumbu at different times, giving rise to the four fundamental Sherpa clans: Minyagpa, Thimmi, Sertawa and Chawa. These four groups gradually split into the more than 20 different clans that exist today. Mahayana Buddhism religious conflict may have contributed to the migration out of Tibet in the 13th and 14th centuries and arrived in Khumbu regions of Nepal. Sherpa migrants travelled through Ü and Tsang, before crossing the Himalaya. By the 1400s , Khumbu Sherpa people attained autonomy within the newly formed Nepali state. In the 1960s, as tension with China increased, the Nepali government influence on the Sherpa people grew. In 1976, Khumbu became a national park, and tourism became a major economic force. Gautam (1994) concluded that the Sherpa migrated from Tibet to Nepal approximately 600 years ago, initially through Rongshar to the west and then later through the Nangpa La pass. It is presumed that the group of people from the Kham region, east of Tibet, was called "Shyar Khamba" (People who came from eastern Kham), and the place where  they settled was called "Shyar Khumbu". As time passed, the "Shyar Khamba", inhabitants of Shyar Khumbu, were called Sherpa. A recent Nepal Ethnographic Museum (2001) study postulated that present-day Nepal became an integral part of the kingdom of Nepal. Since ancient times, Sherpas, like other Kirat Nepalese tribes, would move from one place to another place within the Himalayan region surviving as Alpine pastoralists and traders. Genetics. Genetic studies shows that much of the Sherpa population has allele frequencies which are often found in other Tibeto-Burman regions, in tested genes, the strongest affinity was for Tibetan population sample  studies done in Xizang Tibetan Autonomous Region. Genetically, the Sherpa cluster closest with the sample Tibetan and Han populations. Additionally, the Sherpa had exhibited an affinity for several Nepalese populations, with the strongest for the Rai people, followed by the Magars and the Tamang. A 2010 study identified more than 30 genetic factors that make Tibetans' bodies well-suited for high altitudes, including EPAS1, referred to as the "super-athlete gene" that regulates the body's production of hemoglobin, allowing for greater efficiency in the use of oxygen. A 2016 study of Sherpas in Tibet suggested that a small portion  of Sherpas' and Tibetans' allele frequencies originated from separate ancient populations, which were estimated to have remained somewhat distributed for 11,000 to 7,000 years. Haplogroup distribution. A 2014 study observed that considerable genetic components from the Indian Subcontinent were found in Sherpa people living in Tibet. The western Y chromosomal haplogroups R1a1a-M17, J-M304, and F*-M89 comprise almost 17% of the paternal gene pool in tested individuals. In the maternal side, M5c2, M21d, and U from the west also count up to 8% of people in given Sherpa populations. However, a later study from 2015 did not support the  results from the 2014 study; the 2015 study concluded that genetic sharing from the Indian subcontinent was highly limited; a 2017 study found the same. In a 2015 study of 582 Sherpa individuals (277 males) from China and Nepal, haplogroup D-M174 was found most frequently, followed by Haplogroup O-M175, Haplogroup F-M89 and Haplogroup K-M9. The Y-chromosome haplogroup distribution for Sherpas follow a pattern similar to that for Tibetans. Sherpa mtDNA distribution shows greater diversity, as Haplogroup A was found most frequently, followed by Haplogroup M9a, Haplogroup C4a, Haplogroup M70, and Haplogroup D. These haplogroups are  also found in some Tibetan populations. However, two common mtDNA sub-haplogroups unique to Sherpas populations were identified: Haplogroup A15c1 and Haplogroup C4a3b1. Mountaineering. Many Sherpas are highly regarded as elite mountaineers and experts in their local area. They were valuable to early explorers of the Himalayan region, serving as guides at the extreme altitudes of the peaks and passes in the region, particularly for expeditions to climb Mount Everest. Today, the term is often used by foreigners to refer to almost any guide or climbing supporter hired for mountaineering expeditions in the Himalayas, regardless of their ethnicity. Because of  this usage, the term has become a slang byword for a guide or mentor in other situations. Sherpas are renowned in the international climbing and mountaineering community for their hardiness, expertise, and experience at very high altitudes. It has been speculated that part of the Sherpas' climbing ability is the result of a genetic adaptation to living in high altitudes. Some of these adaptations include unique hemoglobin-binding capacity and doubled nitric oxide production. Deaths in 2014 Everest avalanche. On 18 April 2014, a serac collapsed above the Khumbu Icefall on Mount Everest, causing an avalanche of massive chunks of  ice and snow which killed 16 Nepalese guides, mostly Sherpas. The 2014 avalanche is the second-deadliest disaster in Everest's history, only exceeded by avalanches in the Khumbu Icefall area a year later, on 25 April 2015, caused by a magnitude 7.8 earthquake in Nepal. In response to that tragedy and others involving deaths and injuries sustained by Sherpas hired by climbers, and the lack of government support for Sherpas injured or killed while providing their services, some Sherpa climbing guides walked off the job, and some climbing companies are no longer providing guides and porters for Everest expeditions . The 2014 event killed 16 Sherpas and, in 2015, 10 Sherpas died at the Everest Base Camp after the earthquake. In total, 118 Sherpas have died on this mountain between 1921 and 2018. An April 2018 report by NPR stated that Sherpas account for one-third of Everest deaths. Religion. According to oral Buddhist traditions, the initial Tibetan migration was a search for a beyul (Buddhist pure-lands). Sherpa practise the Nyingmapa, the "Ancient" school of Buddhism. Allegedly the oldest Buddhist sect in Tibet, founded by Padmasambhava (commonly known as Guru Rinpoche) during the 8th century, it emphasizes mysticism and  the incorporation of local deities shared by the pre-Buddhist Bön religion, which has shamanic elements. Sherpa particularly believe in hidden treasures and valleys. Traditionally, Nyingmapa practice was passed down orally through a loose network of lay practitioners. Monasteries with celibate monks and nuns, along with the belief in reincarnated spiritual leaders, are later adaptations. In addition to Buddha and the great Buddhist divinities, the Sherpa also believe in numerous deities and demons who inhabit every mountain, cave, and forest. These have to be respected or appeased through ancient practices woven into the fabric of Buddhist ritual life. Many of  the great Himalayan mountains are considered sacred. The Sherpa call Mount Everest Chomolungma and respect it as the "Mother of the World." Mount Makalu is respected as the deity Shankar (Shiva). Each clan reveres certain mountain peaks and their protective deities. Today, the day-to-day Sherpa religious affairs are presided over by lamas (Buddhist spiritual leaders) and other religious practitioners living in the villages. The village lama who presides over ceremonies and rituals can be a celibate monk or a married householder. In addition, shamans ("lhawa") and soothsayers ("mindung") deal with the supernatural and the spirit world. Lamas identify  witches ("pem"), act as the mouthpiece of deities and spirits, and diagnose spiritual illnesses. An important aspect of Sherpa religion is the temple or "gompa". A gompa is the prayer hall for either villages or monasteries. There are numerous gompas and about two dozen monasteries scattered throughout the Solukhumbu region. The monasteries are communities of lamas or monks (sometimes of nuns) who take a vow of celibacy and lead a life of isolation searching for truth and religious enlightenment. They are respected by and supported by the community at large. Their contact with the outside world is focused on monastery  practices and annual festivals to which the public is invited, as well as the reading of sacred texts at funerals. Traditional clothing. Men wear long-sleeved robes called "kitycow", which fall to slightly below the knee. "Chhuba" is tied at the waist with a cloth sash called "kara", creating a pouch-like space called "tolung" which can be used for storing and carrying small items. Traditionally, "chhuba" were made from thick home-spun wool, or a variant called "lokpa" made from sheepskin. "Chhuba" are worn over "raatuk", a blouse (traditionally made out of "bure", white raw silk), trousers called "kanam , and an outer jacket called tetung". Women traditionally wear long-sleeved floor-length dresses of thick wool called "tongkok". A sleeveless variation called "angi" is worn over a "raatuk" (blouse) in warmer weather. These are worn with colourful striped aprons; "metil" aprons are worn in front, and "gewe" in back, and are held together by an embossed silver buckle called "kyetig". Sherpa clothing resembles Tibetan clothing. Increasingly, home-spun wool and silk is being replaced by factory-made material. Many Sherpa people also now wear ready-made western clothing. Traditional housing. When a son marries and has children, the community  may help to construct a new house, as the extended family becomes too large for a single home. The neighbours often contribute food, drinks and labour to help the family. Houses are typically spaced to allow fields in between. A spiritual ceremony may be conducted at every building stage as the house must have space for deities, humans and animals. Once constructed, the house is often handed down within a family and not sold. The house style depends on the lay of the land: old river terraces, former lake beds or mountain slopes. There are stone single-story, -story (on  a slope), and the two-story houses, with ample room for animals. Many well-to-do families will have an annex shrine room for sacred statues, scriptures and ritual objects. The roof is sloping and is made from local natural materials, or imported metal. There's space in the roof to allow for fire smoke to escape. There may be an internal or external outhouse for making compost. Social gatherings. "A Sherpa community will most commonly get together for a party, which is held by the host with the purpose of gaining favour with the community and neighbours". Guests are  invited hours before the party will start by the host's children to reduce the chance of rejection. The men are seated by order of status, with those of lesser status sitting closer to the door and men of higher status sitting by the fireplace, while the women sit in the center with no ordering. It is polite to sit in a space lower than one's proper place so one may be invited by the host to their proper place. The first several hours of the party will have only beer served, followed by the serving of food, and  then several more hours of singing and dancing before people start to drift out. The act of manipulating one's neighbours into cooperation by hosting a party is known as Yangdzi, and works by expecting the hospitality done by the host with the serving of food and alcohol to be repaid. Notable people. One of the best-known Sherpas is Tenzing Norgay. In 1953, he and Edmund Hillary became the first people known to have reached the summit of Mount Everest. Norgay's son Jamling Tenzing Norgay also climbed Everest in honor of his father with the mountaineers Ed Viesturs  and Araceli Segarra during the disastrous year of 1996. In 2001, Temba Tsheri became the youngest Everest climber in the world (holder of the Guinness World Record), then aged 16. In 2003, Sherpas Pemba Dorje and Lhakpa Golu competed to see who could climb Everest from base camp the fastest. On 23 May 2003, Dorje reached the summit in 12 hours and 46 minutes. Three days later, Golu beat his record by two hours, reaching the summit in 10 hours 46 minutes. On 21 May 2004, Dorje again improved the time by more than two hours with a total time  of 8 hours and 10 minutes. On 11 May 2011, Apa Sherpa successfully reached the summit of Everest for the twenty-first time, breaking his own record for the most successful ascents. He first climbed Mount Everest in 1989 at the age of 29. One of the most famous Nepalese female mountaineers was Pasang Lhamu Sherpa, the first Nepali female climber to reach the summit of Everest, but who died during the descent. Her namesake, Pasang Lamu Sherpa Akita, has also climbed Everest, and was one of three Nepali women who were the first to reach the summit of K2 . Another well-known female Sherpa was the two-time Everest summiter Pemba Doma Sherpa, who died after falling from Lhotse on 22 May 2007. On 20 May 2011, Mingma Sherpa became the first Nepali and the first South Asian to scale all 14 of the world's highest mountains. In the process, Mingma set new world record – he became the first mountaineer to climb all 14 peaks on first attempt. Lakpa Tsheri Sherpa is one half of a Nepali duo that was voted "People's Choice Adventurers of the Year 2012". In April 2011, Lakpa Tsheri and Sano Babu Sunuwar  made the 'Ultimate Descent': a three-month journey in which they climbed Everest, then paraglided down the mountain and proceeded to kayak through Nepal and India until they reached the Indian Ocean. On 19 May 2012, 16-year-old Nima Chhamzi Sherpa became the youngest woman to climb Everest; the previous record holder was Nimdoma Sherpa, who summited in 2008, also at 16 years old. Chhurim Sherpa (Nepal) summitted Everest twice in May 2012: 12 May and 19 May. "Guinness World Records" recognized her for being the first female Sherpa to summit Everest twice in one climbing season. In 2013 , 30-year-old Chhang Dawa Sherpa became the youngest mountaineer to summit the 14 highest peaks, the 8000'ers. Pratima Sherpa is the top-ranked amateur female golfer in Nepal. She was raised in a maintenance shed behind the third hole of the Royal Nepal Golf Club in Kathmandu, where her parents still live. In 2020, Forbes Magazine included her in '30 under 30' list of Asian personalities in entertainment and sports. On 26 July 2014, Pasang Lamu Sherpa Akita, Dawa Yangzum Sherpa, and Maya Sherpa crested the 8,611-metre (28,251 ft) summit of K2, the second highest mountain in the  world. In doing so, the three Nepali women became the first all-female team to climb what many mountaineers consider a much tougher challenge than Everest. The feat was announced in climbing circles as a breakthrough achievement for women in high-altitude mountaineering. Only 18 of the 376 people who have summited K2 have been women. Another notable Sherpa is cross-country skier and ultramarathoner Dachhiri Sherpa, who represented Nepal at the 2006, 2010, and 2014 Winter Olympics. Similarly Cultural and tourism Minister of Nepal Kripasur Sherpa, major of British Gurkha Army Prem Dorji Sherpa, ambassador of Australia Lucky Sherpa  are notable personnel from Sherpa communities. Mountain guide Kami Rita Sherpa holds the world record for the number of successful climbs to the summit of Mount Everest, 23 as of 15 May 2019. Two others, Apa Sherpa and Phurba Tashi Sherpa, have successfully summited on 21 occasions. Mountaineer PK Sherpa and his 14-year-old-son Sonam Sherpa will lead the "First Father and Son Mountaineers" for a global awareness campaign about climate change and global warming. Both father and son will jointly climb all the seven highest summits of seven continents from March 2019 to May 2020. Sherpa people
