The International Mountaineering and Climbing Federation or UIAA recognise eight-thousanders as the 14 mountains that are more than 8,000 metres (26,247 ft) in height above sea level, and are considered to be sufficiently independent from neighbouring peaks. However, there is no precise definition of the criteria used to assess independence and since 2012, the UIAA has been involved in a process to consider whether the list should be expanded to 20 mountains. All eight-thousanders are located in the Himalayan and Karakoram mountain ranges in Asia, and their summits are in the death zone.
The first recorded attempt on an eight-thousander was when Albert F. Mummery and J. Norman Collie tried to climb Pakistan's Nanga Parbat in 1895. The attempt was unsuccessful when Mummery and two Gurkhas, Ragobir, and Goman Singh, were killed by an avalanche.
The first recorded successful ascent of an eight-thousander was by the French Maurice Herzog and Louis Lachenal, who on the 1950 French Annapurna expedition reached the summit of Annapurna on 3 June 1950. The first winter ascent of an eight-thousander was done by a Polish team led by Andrzej Zawada on Mount Everest. Two climbers Leszek Cichy and Krzysztof Wielicki reached the summit on 17 February 1980.
The first person to climb all 14 eight-thousanders was the Italian Reinhold Messner, on 16 October 1986. In 1987, Polish climber Jerzy Kukuczka became the second person to accomplish this feat. Kukuczka is also the man who established the most new routes (9) on the main eight-thousanders. Messner summited each of the 14 peaks without the aid of supplemental oxygen. This feat was not repeated until nine years later by the Swiss Erhard Loretan in 1995. Phurba Tashi of Nepal has completed the most climbs of the eight-thousanders, with 30 ascents between 1998 and 2011. Juanito Oiarzabal has completed the second most, with a total of 25 ascents between 1985 and 2011.
The Italian Simone Moro made the most first winter ascents of eight-thousanders (4); Jerzy Kukuczka made four winter ascents as well, but one was a repetition. As of November 2018[update], K2 remains the only eight-thousander that has never been summited in the winter.
In 2010, Spanish climber Edurne Pasaban, became the first woman to summit all 14 eight-thousanders with no disputed climbing. In August 2011, Austrian climber Gerlinde Kaltenbrunner became the first woman to climb the 14 eight-thousanders without the use of supplementary oxygen.
The first couple and team who summited all 14 eight-thousanders together were the Italians Nives Meroi (second woman without supplementary oxygen), and her husband Romano Benet in 2017. They climbed in alpine style, without the use of supplementary oxygen.
As of November 2018[update], the country with the most climbers to have climbed all 14 eight-thousanders is Italy with seven climbers, followed by Spain with six climbers, and South Korea with five climbers. Kazakhstan and Poland have three climbers each that completed the "Crown of the Himalaya".

In 2012, to relieve capacity pressure, and develop climbing tourism, Nepal lobbied the International Climbing and Mountaineering Federation (or UIAA) to reclassify 5 summits (2 on Lhotse and 3 on Kanchenjunga), as standalone eight-thousanders, while Pakistan lobbied for a sixth summit (on Broad Peak) In 2012, the UIAA set up a project group to consider the proposals called the AGURA Project. The 6 proposed summits for reclassification are subsidiary-summits of existing eight-thousanders, but which are also themselves above 8,000 metres and have a prominence above 60 metres.
|Proposed new eight-thousander||Height (m)||Prominence (m)||Dominance
(Prom / Height)
|Broad Peak Central||8011||181||2,26||B2|
|Kangchenjunga W-Peak (Yalung Kang)||8505||135||1,59||C1|
|Lhotse C-Peak I||8410||65||0,77||C2|
|K 2 SW-Peak||8580||30||0,35||D1|
|Lhotse C-Peak II||8372||37||0,44||D1|
|Yalung Kang Shoulder||8200||40||0,49||D1|
|K 2 P. 8134 (SW-Ridge)||8134||35||0,43||D1|
|Nanga Parbat S-Peak||8042||30||0,37||D1|
|Shisha Pangma C-Peak||8008||30||0,37||D1|
|Everest NE-Pinnacle III||8383||13||0,16||D2|
|Lhotse N-Pinnacle III||8327||10||0,12||D2|
|Lhotse N-Pinnacle II||8307||12||0,14||D2|
|Lhotse N-Pinnacle I||8290||10||0,12||D2|
|Everest NE-Pinnacle II||8282||25||0,30||D2|
The proposed 6 new eight-thousander peaks would not meet the wider UIAA criteria of 600 meters of elevation change between standalone peaks, called topographic prominence, as used by the UIAA elsewhere for major mountains (the lowest prominence of the existing list of 14 eight-thousanders is Lothse, at 610 metres). For example, only Broad Peak Central, with a topographic prominence of 181 meters, would even meet the 150–metre prominence threshold to be a British Isles Marilyn. However, the appeal noted the UIAA's 1994 reclassification of Alpine 4,000 metre peaks where a prominence threshold of 30–metres was used, amongst other criteria; the logic being that if 30–metres worked for 4,000 metres summits, then 60–metres should work for 8,000m summits.
As of November 2018[update], there has been no conclusion by the UIAA and the proposals appear to have been set aside.
Climbers of all 14
There is no single undisputed source for verified Himalayan ascents, however, Elizabeth Hawley's The Himalayan Database, is considered as an important source for the Nepalese Himalayas. Online ascent databases pay close regard to The Himalayan Database, including the website AdventureStats.com, and the Eberhard Jurgalski List. Various mountaineering journals (including the Alpine Journal and the American Alpine Journal), maintain extensive records and archives but do not always opine on ascents.
Climbers with verified ascents
The "No O2" column lists people who have climbed all 14 eight-thousanders without supplementary, oxygen.

Climbers with disputed ascents
Claims in which not enough evidence was provided to verify the ascents of all 14 peaks. The disputed ascent in each claim is shown in parentheses. In most cases, the influential Himalayan chronicler Elizabeth Hawley, is an important source regarding the fact-base of the dispute. Her well-regarded The Himalayan Database is the source for other online Himalayan ascent databases (e.g. AdventureStats.com).
Cho Oyu is a recurrent problem peak as it is a small hump circa 30 mins into the summit plateau, and the main proxy - "Did you see Everest" - requires clear weather. Shishapangma is another problem peak because of its dual summits, which despite being close in height, are up to two hours climbing time apart. Elizabeth Hawley famously got Ed Viesturs to re-climb the main summit of Shishapangma.
|Fausto De Stefani (Lhotse 1997)
(His partner Sergio Martini reclimbed Lhotse in 2000 to verify his 14, see above)
|Alan Hinkes (Cho Oyu 1990)
(Hinkes rejects Hawley's decision to "unrecognise" his Cho Oyu ascent, see "Cho Oyu dispute")
|Vladislav Terzyul (Shishapangma (West) Summit 2000, Broad Peak 1995)
(As he did not claim the main summit of Shishapangma, this status is unlikely to change)
|Eun-Sun Oh (Kangchenjunga 2009)
(As the potential first female climber of all 14, this dispute was followed internationally)
|Carlos Pauner (Shishapangma 2012)
(Pauner is very open about his uncertainty as it was dark, but says he might reclimb to remove the doubt)

- Per The Himalayan Database (HDB) tables, the Climber (or Member) Death Rate is the ratio of deaths above base camp, of all climbers who were hoping to summit and who went above base camp, for 1950 to 2009, and is closer to a true probability of death; the data is only for Nepalese Himalaya. Summary tables from the HDB report for all mountains above 8,000 metres, imply that the death rate for the period 1990 to 2009 (e.g. modern expeditions), is roughly half that of the combined 1950 to 2009 period.
- As recorded by Eberhard Jurgalski
- As recorded by Eberhard Jurgalski and being any death (climber or other) above Base Camp.
- This should not be mistaken as being a death rate; it does not imply a probabiltiy of death for a climber attempting to climb an eight-thousander as it includes all deaths from all activities undertaken above base camp (e.g. training or reconissance trips, camp stocking activities by porters who will not be summiting the mountain, rescue attempts etc.). It therefore compares deaths from the larger group of people who were, and were not, making a summit attempt, with the smaller group who were making a summit attempt. While it is not a probability, the statistic does reflect the ratio of people who died above base camp for each climber who summited.

Nepal is to tackle overcrowding on the world’s highest mountain by placing greater restrictions on expeditions to the summit of Mount Everest. The move is a response to growing problems with litter, pollution and recent clashes between Sherpas and Western climbers. But in an attempt to appease those hoping to conquer the 29,029 feet tall peak, the Nepalese government is to open access to five other summits that sit over 26,246 feet, or 8,000 meters.

- Eberhard Jurgalski. "Dominance". 8000ers.com. Retrieved 23 November 2018.
Accordingly, the author introduced altitude classes (AC) and a proportional prominence, which he named orometrical dominance (D). D is calculated easily but fittingly: (P/Alt) x 100. Thus, it indicates the percentage of independence for every elevation, no matter what the altitude, prominence or mountain type it is. From a scientific point of view, altitude could be seen as the thesis, prominence as the antithesis, whereas dominance would be the synthesis.
- "Do we really need more 8000m peaks". Mark Horrell. 23 October 2013.
The most prominent one, Broad Peak Central is just 196m high and the least prominent, Lhotse Middle, is a meagre 60m. To put this in context, the highest mountain in Malta is 253m, while the Eiffel Tower stands a whopping 300m.

But a South Korean climber, who followed in their footprints on the crusted snow three days later [in 1997] in clearer weather, did not consider that they actually gained the top. While [Sergio] Martini and [Fausto] De Stefani indicated they were perhaps only a few meters below it, Park Young-Seok claimed that their footprints stopped well before the top, perhaps 30 meters below a small fore-summit and 150 vertical meters below the highest summit. Now in 2000 [Sergio] Martini was back again, and this time he definitely summited Lhotse.

But his claim to have now climbed all 8000ers is open to question. In April 1990 he and others reached the summit plateau of Cho Oyu. It was misty so they could not see well; nine years later Hinkes said he had “wandered around for a while” in the summit area but could see very little and eventually descended to join the others, one of whom said they had not reached the top.
