In common usage, the name Mustang refers to the arid
Tibet-like region at the northern end of the Kali Gandaki (known
to its inhabitants as Lo). Mustang is probably a Nepalese
mispronunciation of the name of the capital of Lo, the city of
Manthang. The name is pronounced "Moo-stang" and has nothing to
do with either the automobile or horse with a similar name.
Officially, Mustang is the name of the district along the Kali
Gandaki from the Tibetan border south to Ghasa. The capital of
the Mustang district is Jomsom; the region of Tibetan influence
north of Kagbeni is generally referred to as upper Mustang.
Upper Mustang consists of two distinct regions: the southern
region, with five villages inhabited by people related to the
Manangis; and the northern region (the ancient kingdom of
Lo where the language, culture and traditions are almost
purely Tibetan. The capital of Lo is named Manthang, which translates from the Tibetan as "plain of
aspiration". Many texts refer to the capital as Lo Manthang, but
this is not strictly correct. Other texts spell the name of the
kingdom as Lho, but this is a transliteration of the Tibetan word
for "south" and is also incorrect. Thus the portion of the upper
Mustang district north of Samar is Lo and its capital is
Manthang. The king of Lo is the Lo Gyelbu, though most people use the
Nepalese term raja. To avoid total confusion with existing
maps and texts, this page refers to the capital of Lo as "Lo
Manthang".
It is generally believed that Ame Pal (A-ma-dpal in Tibetan)
was the founder king of Lo in 1380. The ancestry of the present
Mustang raja can be traced 25 generations back to Ame Pal. Ame
Pal, or perhaps his father, conquered a large part of the
territory in the upper Kali Gandaki and was responsible for the
development of the city of Lo Manthang and many gompas. To the
west, the Malla Empire declined and split into numerous petty
hill states. By the 18th century, Jumla had consolidated and
reasserted its power. In an effort to develop their domain as a
trading centre and to obtain Tibetan goods, the rulers of Jumla
turned their attention eastward. In the mid-18th century they
assumed control over Lo, from which they extracted an annual
tribute.
When he ascended the throne in 1762, Prithvi Narayan Shah began to consolidate what is present-day Nepal. At the time of his death, the kingdom extended from Gorkha eastward to the borders of Sikkim. His descendants directed their efforts westward and by 1789, Jumla had been annexed. The Gorkha armies never actually entered Lo; they recognised the rule of the Mustang raja. Although Mustang became part of Nepal, the raja retained his title and Lo retained a certain amount of autonomy. Lo maintained its status as a separate principality until 1951. After the Rana rulers were overthrown and King Tribhuvan re-established the rule of the Shah monarchs on 15 February, 1951, Lo was more closely consolidated into Nepal. The raja was given the honorary rank of colonel in the Nepalese army. During the 1960s, after the Dalai Lama had fled to India and Chinese armies established control over Tibet, Mustang was a centre for guerrilla operations against the Chinese. The soldiers were the Khampas, Tibet's most fearsome warriors who were backed by the CIA (some Khampas were secretly trained in the USA). At the height of the fighting there were at least 6000 Khampas in Mustang and neighbouring border areas. The CIA's support ended in the early 1970s when the USA, under Kissinger and Nixon, initiated new and better relations with the Chinese. The government of Nepal was pressed to take action against the guerrillas and, making use of internal divisions within the Khampa leadership, a bit of treachery, and the Dalai Lama's taped advice for his citizens to lay down their arms, it managed to disband the resistance without committing to action the 10,000 Nepalese troops that had been sent to the area.
Though Mustang was closed, the government allowed a few
researchers into the area. Toni Hagen included Mustang in his
survey of the entire kingdom of Nepal, and the Italian scholar
Giuseppi Tucci visited in the autumn of 1952. Professor David
Snellgrove travelled to the region in 1956 but did not visit Lo
Manthang. Longtime Nepal resident Barbara Adams travelled to
Mustang during the autumn of 1963. The most complete description
of the area is Mustang, the Forbidden Kingdom, written by
Michel Peissel who spent several months in the area in the spring
of 1964. Dr Harka Bahadur Gurung also visited and wrote about
upper Mustang in October 1973. A number of groups legally
travelled to upper Mustang during the 1980s by obtaining permits
to climb Bhrikuti peak (6364 metres) south-east of Lo Manthang.
Other than a few special royal guests, the first legal trekkers
were allowed into Mustang in March 1992 upon payment of a high
fee for a special trekking permit.
The trek to Lo is through an almost treeless barren landscape. Strong winds usually howl across the area in the afternoon, generally subsiding at night. Being in the rain shadow of the Himalaya, Lo has much less rain than the rest of Nepal. During the monsoon the skies are cloudy and there is some rain. In the winter there is usually snow; sometimes as much as 30 or 40 cm accumulates on the ground.
In Lo itself the countryside is similar to the Tibetan plateau with its endless expanses of yellow and grey rolling hills eroded by wind. There is more rain in the lower part of upper Mustang and the hills tend to be great red fluted cliffs of tiny round stones cemented together by mud. Villages are several hours apart and appear in the distance almost as mirages; during the summer season, after the crops are planted, they are green oases in the desert-like landscape.

Because of the cold and snow, most of the population departs from Lo on trading expeditions during the winter. The trekking season, therefore, is from late March until early November. The trek does not go to extremely high elevations, but the cold, dust and unrelenting afternoon winds can make the trek less pleasant than other treks in Nepal.
