Durand Line in the context of "Sphere of influence"

Afghanistan, officially the Islamic Emirate of Afghanistan, is a landlocked country located at the crossroads of Central and South Asia. It is bordered by Pakistan to the east and south, Iran to the west, Turkmenistan to the northwest, Uzbekistan to the north, Tajikistan to the northeast, and China to the northeast and east. Occupying 652,864 square kilometers (252,072 sq mi) of land, the country is predominantly mountainous with plains in the north and the southwest, which are separated by the Hindu Kush mountain range. Kabul is the country's capital and largest city. Afghanistan's population is estimated to be between 40 and 50 million.

Human habitation in Afghanistan dates to the Middle Paleolithic era. Popularly referred to as the graveyard of empires, the land has witnessed numerous military campaigns, including those by the Persians, Alexander the Great, the Maurya Empire, Arab Muslims, the Mongols, the British, the Soviet Union, and a US-led coalition. Afghanistan also served as the source from which the Greco-Bactrians and the Mughals, among others, rose to form major empires. Because of the various conquests and periods in both the Iranian and Indian cultural spheres, the area was a center for Zoroastrianism, Buddhism, Hinduism, and later Islam. The modern state of Afghanistan began with the Durrani Afghan Empire in the 18th century, although Dost Mohammad Khan is sometimes considered to be the founder of the first modern Afghan state. Afghanistan became a buffer state in the Great Game between the British Empire and the Russian Empire. From India, the British attempted to subjugate Afghanistan but were repelled in the First Anglo-Afghan War; the Second Anglo-Afghan War saw a British victory. Following the Third Anglo-Afghan War in 1919, Afghanistan became free of foreign political hegemony, and emerged as the independent Kingdom of Afghanistan in 1926. This monarchy lasted almost half a century, until Zahir Shah was overthrown in 1973, following which the Republic of Afghanistan was established.

The Wakhan Corridor (Dari: دالان واخان, romanized: Dālān-i Wāxān; Pashto: واخان دهلېز, romanized: Wāxān dahlez) is a narrow strip of territory in the Badakhshan province of Afghanistan. This corridor stretches eastward, connecting Afghanistan to Xinjiang, China. It also separates the Gorno-Badakhshan Autonomous Region of Tajikistan in the north from the Khyber Pakhtunkhwa and Gilgit-Baltistan regions in Pakistan in the south. This high mountain valley, which rises to a maximum altitude of 4,923 m (16,152 ft), serves as the source of both the Panj and Pamir rivers, which converge to form the larger Amu Darya River. For countless centuries, a vital trade route has traversed this valley, facilitating the movement of travelers to and from East, South, and Central Asia.

The corridor was formed after an 1893 out of British territory from now Pakistan after an agreement between Mortimer Durand of the British Raj and Emir Abdur Rahman Khan of Afghanistan, so that the Russian dominion, now Tajikistan would not touch British dominion, now Pakistan. This agreement also created the Durand Line which today forms the border between Pakistan and Afghanistan. It was last conquered by the Durrani Empire in 1763. At the time it was carved out, the narrow strip acted as a buffer zone between the Russian Empire and the British Empire (specifically the regions of Russian Turkestan, now in Tajikistan, and the northern part of the British Raj, now in Pakistan). Its eastern end bordered China's Xinjiang region, then claimed by the Qing dynasty.

Khyber Pakhtunkhwa, commonly abbreviated KP or KPK and formerly known as the North-West Frontier Province (NWFP), is a province of Pakistan. Located in the northwestern region of the country, Khyber Pakhtunkhwa is the fourth largest province of Pakistan by land area and the third-largest province by population. It is bordered by Balochistan to the south; Punjab, Islamabad Capital Territory, and Azad Kashmir to the east; and Gilgit-Baltistan to the north and northeast. It shares an international border with Afghanistan to the west. Khyber Pakhtunkhwa has a varied geography of rugged mountain ranges, valleys, rolling foothills, and dense agricultural farms.

The history of the present province of Khyber Pakhtunkhwa is characterized by frequent invasions by various empires, largely due to its geographical proximity to the historically important Khyber Pass. It was the site of the ancient Gandhara, and was historically a stronghold of Buddhism. Islam became dominant in the region after the 11th-century conquest of the Hindu Shahi kingdom by the Ghaznavids. The predecessor of the present province was constituted in 1901, under the British Raj, when the North-West Frontier Province was created by bifurcating the northwestern districts of the erstwhile Punjab Province.

Sir Henry Mortimer Durand, GCMG, KCSI, KCIE, PC (14 February 1850 – 8 June 1924) was a British diplomat and member of the Indian Civil Service. He is best-known as the namesake for the Durand Line, which serves as the international border between Afghanistan and Pakistan.

Abdur Rahman Khan GCSI (Pashto; Persian: عبدالرحمن خان, between 1840 and 1844 – 1 October 1901), also known by his epithet, The Iron Emir, was Emir of Afghanistan from 1880 to his death in 1901. He is known for perpetrating the Hazara genocide, and suppressing Hazara rebels in the most brutal ways, while uniting the country after years of strong centralization, internal fighting, and negotiation of the Durand Line agreement with British India.

Abdur Rahman Khan was the only son of Mohammad Afzal Khan, and grandson of Dost Mohammad Khan, founder of the Barakzai dynasty. Abdur Rahman Khan re-established the writ of the Afghan government after the disarray that followed the second Anglo-Afghan war. He became known as The Iron Amir because of his government's military despotism. This despotism rested upon a well-appointed army and was administered through officials subservient to an inflexible will and controlled by a widespread system of espionage.

Chitral District (Khowar: ݯھیترارو ضلع; Urdu: ضلع چترال) was a district in the Malakand Division of the Pakistani province of Khyber Pakhtunkhwa from 14 August 1947 to 2018. It was the northernmost and the largest district of the province, covering an area of 14,850 km, before the district was split in two forming the new districts of Upper Chitral and Lower Chitral.

It shared district borders with Swat and Dir to the south, a provincial border with Gilgit-Baltistan to the east and the Durand Line as international border with Afghanistan to the north and west. Afghanistan's narrow strip of Wakhan Corridor separated Chitral from Tajikistan in the north.

The Nuristanis are an Indo-Iranian ethnic group native to the Nuristan Province (formerly Kafiristan) of northeastern Afghanistan and Chitral District of northwestern Pakistan. Their languages comprise the Nuristani branch of Indo-Iranian languages.

In the mid-1890s, after the establishment of the Durand Line when Afghanistan and the British Indian Empire reached an agreement regarding the Indo-Afghan border as the region of Kafiristan became part of the Great Game and for a period of time, Emir Abdur Rahman Khan conducted a military campaign to secure the eastern regions and followed up his conquest by imposition of Islam; the region thenceforth being known as Nuristan, the "Land of Light". Before their conversion, the Nuristanis practised an Indo-Iranian (Vedic- or Hindu-like) religion. Non-Muslim religious practices endure in Nuristan today to some degree as folk customs. In their native rural areas, they are often farmers, herders, and dairymen.

Pashtunistan (Pashto: پښتونستان, lit. 'land of the Pashtuns') or Pakhtunistan is a historical region on the crossroads of Central and South Asia, located on the Iranian Plateau, inhabited by the Pashtun people of southern and eastern Afghanistan and northwestern Pakistan, wherein Pashtun culture, the Pashto language, and identity have been based. Alternative names historically used for the region include Pashtūnkhwā or Pakhtūnkhwā (پښتونخوا), or simply the Pashtun Belt.

During British rule in India in 1893, Mortimer Durand drew the Durand Line, fixing the limits of the spheres of influence between the Emirate of Afghanistan and British India during the Great Game and leaving about half of historical Pashtun territory under British colonial rule; after the partition of British India, the Durand Line now forms the internationally recognized border between Afghanistan and Pakistan. The traditional Pashtun homeland stretches roughly from the areas south of the Amu River in Afghanistan to the areas west of the Indus River in Pakistan; it predominantly comprises the southwestern, eastern and some northern and western districts of Afghanistan, as well as most of Khyber Pakhtunkhwa and northern Balochistan in Pakistan. The region is bordered by Punjab and Hazara to the east, Balochistan to the south, Kohistan and Chitral to the north, and Hazarajat and Tajik-inhabited territory to the west.
