The Trans himalaya (also spelled Trans-Himalaya ), or " Gangdise – Nyenchen Tanglha range " ( Chinese : 冈底斯-念青唐古拉山脉 ; pinyin : Gāngdǐsī-Niànqīngtánggǔlā Shānmài ), is a 1,600-kilometre-long (990 mi) mountain range in China , India and Nepal , extending in a west–east direction parallel to the main Himalayan range. Located north of Yarlung Tsangpo river on the southern edge of the Tibetan Plateau , the Transhimalaya is composed of the Gangdise range to the west and the Nyenchen Tanglha range to the east.
105-595: The name Transhimalaya was introduced by the Swedish geographer Sven Hedin in early 20th century. The Transhimalaya was described by the Columbia Lippincott Gazetteer in 1952 as an "ill-defined mountain area" with "no marked crest line or central alignment and no division by rivers." On more-modern maps the Kailas Range (Gangdise or Kang-to-sé Shan) in the west is shown as distinct from

He also found a wooden wheel from a horse-drawn cart (called an arabas ) as well as several hundred documents written on wood, paper and silk in the Kharosthi script. These provided information about the history of the city of Loulan , which had once been located on the shores of Lop Nur but had been abandoned around the year 330 CE because the lake had dried out, depriving
315-851: A Swedish legation to Iran which was to present the Shah of Iran with the insignia of the Order of the Seraphim . As part of the Swedish legation, he was at an audience of the shah Naser al-Din Shah Qajar in Tehran. He spoke with him and later accompanied him to the Elburz Mountain Range. On 11 July 1890, he and three others climbed Mount Damavand where he collected primary material for his dissertation. Starting in September he traveled on

From 1886 to 1888, Hedin studied under the geologist Waldemar Brøgger in Stockholm and Uppsala the subjects of geology, mineralogy , zoology and Latin . In December 1888, he became a Candidate in Philosophy . From October 1889 to March 1890 he studied in Berlin under Ferdinand Freiherr von Richthofen . On 12 May 1890, he accompanied as interpreter and vice-consul
525-418: A bookish, bespectacled appearance, Hedin nevertheless proved himself a determined explorer, surviving several close brushes with death from hostile forces and the elements over his long career. His scientific documentation and popular travelogues, illustrated with his own photographs, watercolor paintings and drawings, his adventure stories for young readers and his lecture tours abroad made him world-famous. As

According to other sources, Hedin had neglected to completely fill the drinking water containers for his caravan at the beginning of
735-595: A cold, arid montane climate. For example, the Spiti region of Himachal Pradesh , India, has an annual rainfall of about 170 mm. However, studies in Mustang District , Nepal, indicate that climate change is warming the Transhimalayas at a rate of about 0.13 degrees a year. The Transhimalayas generally have low species diversity (and vegetation cover) and are classified as dry alpine steppes. However,
840-544: A crisis and the dissolution of parliament . Ahmad Shah Qajar and his entourage decided to leave Tehran and move the capital to another place, sparking fears of rebellion in other cities. During the Battle of Robat Karim , Iranian forces led by Heydar Latifiyan prevented the Russians from taking Tehran, despite the latter winning the battle. This also allowed government functions to be moved to Qom and then to Isfahan, while
945-481: A grand total of only eight months and collecting primary material for one-and-a-half days on the snow-clad peak of Mount Damavand . Ferdinand Freiherr von Richthofen not only encouraged Hedin to absolve cursory studies, but also to become thoroughly acquainted with all branches of geographic science and the methodologies of the salient research work, so that he could later work as an explorer. Hedin abstained from doing this with an explanation he supplied in old age: I
1050-613: A renowned expert on Turkestan and Tibet, he was able to obtain unrestricted access to European and Asian monarchs and politicians as well as to their geographical societies and scholarly associations. They all sought to purchase his exclusive knowledge about the power vacuum in Central Asia with gold medals, diamond-encrusted grand crosses, honorary doctorates and splendid receptions, as well as with logistic and financial support for his expeditions. Hedin, in addition to Nikolai Przhevalsky , Sir Francis Younghusband , and Sir Aurel Stein ,
1155-873: A stopover in Kashgar, Hedin visited the 1,500-year-old abandoned cities of Dandan Oilik and Kara Dung , which are located northeast of Khotan in the Taklamakan Desert. At the beginning of March, he discovered Lake Bosten , one of the largest inland bodies of water in Central Asia. He reported that this lake is supplied by a single mighty feeder stream, the Kaidu River . He mapped Lake Kara-Koshun and returned on 27 May to Khotan. On 29 June, he started out from there with his caravan across northern Tibet and China to Beijing, where he arrived on 2 March 1897. He returned to Stockholm via Mongolia and Russia. Another expedition in Central Asia followed in 1899–1902 through

In English, it is also spelt " Teheran ", with both variants being used in books since at least 1800, and "Teheran" being the dominant form from after WWII until shortly before the Islamic Revolution. Archaeological remains from the ancient city of Ray suggest that settlement in Tehran dates back over 6,000 years. Tehran is in the historical Media region of ( Old Persian : 𐎶𐎠𐎭 Māda ) in northwestern Iran. By

In 2016, the Tehran City Council declared 6 October to be Tehran Day, celebrating the date in 1907 when the city officially became the capital of Iran. Various theories on the origin of the name Tehran have been put forward. Iranian linguist Ahmad Kasravi , in an article "Shemiran-Tehran", suggested that Tehran and Kehran mean "the warm place", and "Shemiran" means "the cool place". He listed cities with

In Mustang, Nepal, rising temperatures and declining snowfall are reducing the area available for agriculture, forcing villagers to relocate and reducing grassland and forest cover. This has also led to bharal shifting to lower elevations, where they raid crops. In turn, this attracts snow leopards to human settlements, where they prey on livestock. On
2520-615: The Mongol invasion . In the 13th century, the Mongols invaded Rhages, laid the city to ruins, and massacred many of its inhabitants. Others escaped to Tehran. In July 1404, Castilian ambassador Ruy González de Clavijo visited Tehran on a journey to Samarkand , the capital of Turco-Mongol conqueror Timur , the ruler of Iran at the time. He described it in his diary as an unwalled region. Italian traveler Pietro della Valle passed through Tehran overnight in 1618, and in his memoirs called

Having left all they had and having struggled to adapt to a new country and build a life, most of them never came back when the war was over. During the war, Tehran also received a great number of migrants from the west and

They were probably formed by subduction of sediments from the collision of the Indian and Eurasian plates. A consensus of different dating methods suggests that the older parts of this range formed in the upper Cretaceous (82-113 Mya), while the younger regions formed in the Eocene (40-60 Mya). The Transhimalays generally have

He remained in Kashgar until April 1895 and then left on 10 April with three local escorts from the village of Merket to cross the Taklamakan Desert via Tusluk to the Khotan River . Since their water supply was insufficient, seven camels died of thirst, as did two of his escorts (according to Hedin's dramatized and probably inaccurate account). Bruno Baumann traveled on this route in April 2000 with

One aspect of the geography of central Asia which intensively occupied Hedin for decades was what he called the "wandering lake" Lop Nur . In May 1934, he began a river expedition to this lake. For two months he navigated the Kaidu River and the Kum-Darja to Lop Nur, which had been filled with water since 1921. After

Although he was not a National Socialist , Hedin's hope that Nazi Germany would protect Scandinavia from invasion by the Soviet Union , brought him in dangerous proximity to representatives of National Socialism, who exploited him as an author. This destroyed his reputation and put him into social and scientific isolation. However, in correspondence and personal conversations with leading Nazis, his successful intercessions achieved

Up until the 1870s, Tehran consisted of a walled citadel, a roofed bazaar , and the three main neighborhoods of Udlajan , Chale-Meydan, and Sangelaj, where the majority resided. During the long reign of Naser al-Din Shah (1848-1896), Tehran witnessed Iran's first institute of higher learning , bank , railway line and museum. The city expanded rapidly through multiple development plans The first development plan of Tehran in 1855 emphasized traditional spatial structure. The second, under

Obsessed by his urge to carry out his research, Hedin deserted the caravan and proceeded alone on horseback with his servant. When that escort also collapsed from thirst, Hedin left him behind as well, but managed to reach a water source at the last desperate moment. He did, however, return to his servant with water and rescued him. Nevertheless, his ruthless behavior earned him massive criticism. In January 1896, after

7770-533: The planning organization of Iran in 1948 resulted in the first socioeconomic development plan to cover from 1949 to 1955. These plans not only failed to slow the unbalanced growth of Tehran but with the 1962 land reforms that Reza Shah's son and successor Mohammad Reza Shah named the White Revolution , Tehran's chaotic growth was further accentuated. Throughout the 1960s and 1970s, Tehran developed rapidly under Mohammad Reza Shah. Modern buildings altered

In recognition of his achievements, the Berlin Geographical Society presented him with the Ferdinand von Richthofen Medal in 1933; the same honor was also awarded to Erich von Drygalski for his Gauss Expedition to the Antarctic ; and to Alfred Philippson for his research on
7980-462: The result was that Hedin had to leave the evaluation of his expedition results later to other scientists. Between 1894 and 1908, in three daring expeditions through the mountains and deserts of Central Asia , he mapped and researched parts of Chinese Turkestan (now Xinjiang ) and Tibet which had been unexplored by Europeans until then. Upon his return to Stockholm in 1909 he was received as triumphantly as Adolf Erik Nordenskiöld. In 1902, he became
8085-475: The sacred Lake Manasarovar and Mount Kailash , the midpoint of the earth according to Buddhist and Hindu mythology.

8400-465: The scientific material assembled during the expedition was published in over 50 volumes by Hedin and other expedition participants, thereby making it available for worldwide research on eastern Asia. When he ran out of money to pay printing costs, he pawned his extensive and valuable library, which filled several rooms, making possible the publication of additional volumes. In 1935, Hedin made his exclusive knowledge about Central Asia available, not only to

The unstable situation and the war in neighbouring Afghanistan and Iraq prompted a rush of refugees into the country who arrived in millions, with Tehran being a magnet for many seeking work, who subsequently helped the city to recover from war wounds, working for a far lower pay than local construction workers. Many of these refugees are being repatriated with

After a less-than-successful lecture tour in 1923 through North America and Japan, he traveled on to Beijing to carry out an expedition to Chinese Turkestan (modern Xinjiang), but the region's unstable political situation thwarted this intention. He instead traveled through Mongolia by car and through Siberia aboard
