Pamir Mountains in the context of "Lake Zorkul"

South Asia is the southern subregion of Asia that is defined in both geographical and ethnic-cultural terms. South Asia, with a population of 2.04 billion, contains a quarter (25%) of the world's population. As commonly conceptualised, the modern states of South Asia include Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka, with Afghanistan also often included, which may otherwise be classified as part of Central Asia. South Asia borders East Asia to the northeast, Central Asia to the northwest, West Asia to the west and Southeast Asia to the east. Apart from Southeast Asia, Maritime South Asia is the only subregion of Asia that lies partly within the Southern Hemisphere. The British Indian Ocean Territory and two out of 26 atolls of the Maldives in South Asia lie entirely within the Southern Hemisphere. Topographically, it is dominated by the Indian subcontinent and is bounded by the Indian Ocean in the south, and the Himalayas, Karakoram, and Pamir Mountains in the north.

Settled life emerged on the Indian subcontinent in the western margins of the Indus River Basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. By 1200 BCE, an archaic form of Sanskrit, an Indo-European language, had diffused into India from the northwest, with the Dravidian languages being supplanted in the northern and western regions. By 400 BCE, stratification and exclusion by caste had emerged within Hinduism, and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity.

The Qing dynasty (/tʃɪŋ/ CHING), officially the Great Qing, was a Manchu-led imperial dynasty of China and an early modern empire in East Asia. The last imperial dynasty in Chinese history, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. At its height of power, the empire stretched from the Sea of Japan in the east to the Pamir Mountains in the west, and from the Mongolian Plateau in the north to the South China Sea in the south. Originally emerging from the Later Jin dynasty founded in 1616 and proclaimed in Shenyang in 1636, the dynasty seized control of the Ming capital Beijing and North China in 1644, traditionally considered the start of the dynasty's rule. The dynasty lasted until the Xinhai Revolution of October 1911 led to the abdication of the last emperor in February 1912. The multi-ethnic Qing dynasty assembled the territorial base for modern China. The Qing controlled the most territory of any dynasty in Chinese history, and in 1790 represented the fourth-largest empire in world history to that point. With over 426 million citizens in 1907, it was the most populous country at the time.

Nurhaci, leader of the Jianzhou Jurchens and House of Aisin-Gioro who was also a vassal of the Ming dynasty, unified Jurchen clans (known later as Manchus) and founded the Later Jin dynasty in 1616, renouncing the Ming overlordship. As the founding Khan of the Manchu state he established the Eight Banners military system, and his son Hong Taiji was declared Emperor of the Great Qing in 1636. As Ming control disintegrated, peasant rebels captured Beijing as the short-lived Shun dynasty, but the Ming general Wu Sangui opened the Shanhai Pass to the Qing army, which defeated the rebels, seized the capital, and took over the government in 1644 under the Shunzhi Emperor and his prince regent. While the Qing became a Chinese empire, resistance from Ming rump regimes and the Revolt of the Three Feudatories delayed the complete conquest until 1683, which marked the beginning of the High Qing era. As an emperor of Manchu ethnic origin, the Kangxi Emperor (1661–1722) consolidated control, relished the role of a Confucian ruler, patronised Buddhism, encouraged scholarship, population and economic growth.

Kyrgyzstan, officially the Kyrgyz Republic, is a landlocked country in Central Asia, lying in the Tian Shan and Pamir mountain ranges. It is bordered by Kazakhstan to the north, Uzbekistan to the west, Tajikistan to the south, and China to the east and southeast. Bishkek is the capital and largest city. Ethnic Kyrgyz make up the majority of the country's over 7 million people, followed by significant minorities of Uzbeks and Russians.

Kyrgyzstan's history spans a variety of cultures and empires. Although geographically isolated by its highly mountainous terrain, Kyrgyzstan has been at the crossroads of several great civilizations as part of the Silk Road along with other commercial routes. Inhabited by a succession of tribes and clans, Kyrgyzstan has periodically fallen under larger domination, for example the Turkic nomads, who trace their ancestry to many Turkic states. It was first established as the Yenisei Kyrgyz Khanate. Later, in the 13th century, Kyrgyzstan was conquered by the Mongol Empire and under several Mongol dynasties; it regained independence, but was later invaded by the Dzungar Khanate. After the fall of Dzhungars, Kyrgyz and Kipchaks were an integral part of Kokand Khanate.

The Hindu Kush is an 800-kilometre-long (500 mi) mountain range in Central and South Asia to the west of the Himalayas. It stretches from central and eastern Afghanistan into northwestern Pakistan and far southeastern Tajikistan. The range forms the western section of the Hindu Kush Himalayan Region (HKH); to the north, near its northeastern end, the Hindu Kush buttresses the Pamir Mountains to the north near the point where the borders of China, Pakistan and Afghanistan meet, after which it runs southwest through Pakistan and into Afghanistan near their border.

The eastern end of the Hindu Kush merges with the Karakoram Range. Towards its southern end, it connects with the White Mountains near the Kabul River. It divides the valley of the Amu Darya (the ancient Oxus) to the north from the Indus River valley to the south. The range has numerous high snow-capped peaks, with the highest point being Tirich Mir or Terichmir at 7,708 metres (25,289 ft) in the Chitral District of Khyber Pakhtunkhwa, Pakistan.

The Karakoram (/ˌkɑːrəˈkɔːrəm, ˌkær-/) is a mountain range in Asia located primarily in the Kashmir region. The range spans the borders of Pakistan, China, and India, with the north-western extremities of the range extending into Afghanistan and Tajikistan. The Karakoram contains four of the fourteen eight-thousanders, the highest of which is K2, the second highest mountain on Earth.

The Karakoram begins in the Wakhan Corridor in western Afghanistan and extends eastwards into Indian-administered Ladakh and Chinese-administered Aksai Chin, as well as the Chinese province of Xinjiang. Most of the Karakoram is located within the Pakistani-administered Gilgit-Baltistan region. The Karakoram is bounded on the east by the Aksai Chin plateau, on the north-east by the edge of the Tibetan Plateau, and on the north by the river valleys of the Yarkand and Karakash rivers, beyond which lie the Kunlun Mountains. At the north-west corner are the Pamir Mountains. The southern boundary of the Karakoram is formed west to east by the Gilgit, Indus, and Shyok rivers, which separate the range from the north-western end of the Himalaya. These rivers flow north-west before making an abrupt turn south-westwards towards the plains of Pakistan. Roughly in the middle of the Karakoram range is the Karakoram Pass, which was part of a now unused trade route between Ladakh and Yarkand.

Bactria (/ˈbæktriə/; Bactrian: βαχλο, Bakhlo), or Bactriana, was an ancient Iranian civilization in Central Asia, located in the area south of the Oxus River (modern Amu Darya) and north of the Hindu Kush mountains, within modern-day Afghanistan, Tajikistan and Uzbekistan. Bactria was strategically located south of Sogdia and west of the Pamir Mountains. These mountain ranges acted as "walls" protecting Bactria from three sides, with the Pamir mountains to the north and the Hindu Kush to the south forming a junction, and the Karakoram range towards the east.

Called "beautiful Bactria, crowned with flags" by the Avesta, the region is considered, in the Zoroastrian faith, to be one of the "sixteen perfect Iranian lands" that the supreme deity, Ahura Mazda, had created. It was once a small and independent kingdom struggling to survive against nomadic Turanians. One of the early centres of Zoroastrianism, and capital of the legendary Kayanian dynasty, Bactria is mentioned in the Behistun Inscription of Darius the Great as one of the satrapies of the Achaemenid Empire; it was a special satrapy, ruled by a crown prince or an intended heir. Bactria was the centre of Iranian resistance against the Greek Macedonian invaders after the fall of the Achaemenid Empire in the 4th century BC, but eventually fell to Alexander the Great.

The Taklamakan Desert (/ˌtækləməˈkæn/ TAK-lə-mə-KAN) is a desert in northwest China. Located inside the Tarim Basin in Southern Xinjiang, it is bounded by the Kunlun Mountains to the south, the Pamir Mountains to the west, the Tian Shan range to the north, and the Gobi Desert to the east.
