Peshawar in the context of "Pakistan Railways"

The Durrani Empire, colloquially known as the Kingdom of Afghanistan, Afghan Empire or the Sadozai Kingdom, was an Afghan empire founded by the Durrani tribe of Pashtuns under Ahmad Shah Durrani in 1747, which spanned parts of Central Asia, the Iranian plateau, and the Indian subcontinent. At its peak, it ruled over present-day Afghanistan, much of Pakistan, parts of northeastern and southeastern Iran, eastern Turkmenistan, and northwestern India. Next to the Ottoman Empire, the Durrani Empire is considered to be among the most significant Islamic empires of the second half of the 18th century.

Ahmad was the son of Muhammad Zaman Khan (an Afghan chieftain of the Abdali tribe) and the commander of Nader Shah Afshar. Following Afshar's death in June 1747, Ahmad secured Afghanistan by taking Kandahar, Ghazni, Kabul, and Peshawar. After his accession as the nation's king, he changed his tribal name from Abdali to Durrani. In 1749, the Mughal Empire had ceded sovereignty over much of northwestern India to the Afghans; Ahmad then set out westward to take possession of Mashhad, which was ruled by the Afsharid dynasty under Shahrokh Shah, who also acknowledged Afghan suzerainty. Subsequently, Ahmad sent an army to subdue the areas north of the Hindu Kush down to the Amu Darya, and in short order, all of the different Afghan tribes began to join his cause. Under Ahmad, the Afghans invaded India on eight occasions, subjugating parts of Kashmir and the majority of Punjab. In early 1757, he sacked Delhi, but permitted Mughal emperor Alamgir II to remain in nominal control as long as he acknowledged Afghan suzerainty over the regions south of the Indus River, till Sutlej river.

Pushkalavati was the capital of the ancient region of Gāndhāra, situated in present day's Pakistan. Its ruins are located on the outskirts of the modern city of Charsadda, in Charsadda District, in the Khyber Pakhtunkhwa, 35-42 kilometres northeast of Peshawar, at the banks of Jindi River, near the junction of Swat River with Kabul River. The earliest archaeological remains in Bala Hisar mound are from 1400 to 800 BCE. Pushkalavati (in Bala Hisar mound) may have been incorporated as an Achaemenid regional settlement around 520 BCE, and it remained an important city (in Shaikhan Dheri mound) through to the beginning of the 3rd century CE.

The ruins of Pushkalavati consist of two sites, separated by the small Shambor river. To the south is Bala Hisar, which consists of two separate mounds, one eastern and one western. To the north is Shaikhan Dheri, wedged between the Shambor and Jindi rivers.

The North-West Frontier Province (abbr. NWFP), commonly known as Sarhad (lit. 'Frontier'), was a province of Pakistan from 1947 to 1955 and from 1970 to 2010; and prior, a province of British India from its establishment in 1901 to Pakistan's independence in 1947. It was established from the north-western districts of British Punjab during the British Raj. Following the referendum in 1947 to join either Pakistan or India, the province voted hugely in favour of joining Pakistan and it acceded accordingly on 14 August 1947. It was dissolved to form a unified province of West Pakistan in 1955 upon promulgation of One Unit Scheme and was reestablished in 1970. It was known by this name until 19 April 2010, when it was dissolved and redesignated as the province of Khyber Pakhtunkhwa following the enactment of the Eighteenth Amendment to the Constitution of Pakistan.

The province covered an area of 70,709 km (27,301 sq mi), including much of the current Khyber Pakhtunkhwa province but excluding the Federally Administered Tribal Areas and the former princely states of Amb, Chitral, Dir, Phulra and Swat. Its capital was the city of Peshawar, and the province was composed of six divisions (Bannu, Dera Ismail Khan, Hazara, Kohat, Mardan, and Peshawar Division; Malakand was later added as the seventh division). Until 1947, the province was bordered by five princely states to the north, the minor states of the Gilgit Agency to the northeast, the province of Punjab to the east and the province of Balochistan to the south. The Kingdom of Afghanistan lay to the northwest, with the Federally Administered Tribal Areas forming a buffer zone between the two.

Gilgit (/ˈɡɪlɡɪt/; Shina: گِلیٗت IPA: [ɡi˧.leː˨˦t̪]; Urdu: گِلْگِت IPA: [ˈɡɪlɡɪt̪]) is the capital and most-populous city in Pakistani-administered Gilgit–Baltistan in the disputed Kashmir region. It is located in a broad valley near the confluence of the Gilgit and the Hunza rivers. It is a major tourist destination in Pakistan, serving as a hub for trekking and mountaineering expeditions in the Karakoram mountain range of Northern Pakistan.

Gilgit was once a major centre for Buddhism; it was an important stop on the ancient Silk Road, and today serves as a major junction along the Karakoram Highway with road connections to China as well as the Pakistani cities of Skardu, Chitral, Peshawar, and Islamabad. The city's economic activity is mainly focused on agriculture, with wheat, maize, and barley as the main crops.

The Valley of Peshawar (Pashto: د لوی پېښور وادي; Urdu: وادئ پشاور) is a broad area situated in the central part of the Khyber Pakhtunkhwa province of Pakistan. The valley is 7,176 km (2,771 sq mi) in area, and is traversed by the Kabul River. It has a mean elevation of 345 metres (1,132 ft). The valley takes its name from the city of Peshawar, which is situated at the western part of the valley close to Warsak Dam. To the west of the valley lies the Khyber Pass. The five most populous cities in the valley are Peshawar, Mardan, Swabi, Charsadda, and Nowshera.

Kanishka I, also known as Kanishka the Great, was an emperor of the Kushan dynasty, under whose reign (c. 127–150 CE) the empire reached its zenith. He is famous for his military, political, and spiritual achievements. A descendant of Kujula Kadphises, founder of the Kushan empire, Kanishka came to rule an empire extending from Central Asia and Gandhara to Pataliputra on the Gangetic plain. The main capital of his empire was located at Puruṣapura (Peshawar) in Gandhara, with another major capital at Mathura. Coins of Kanishka were found in Tripuri (present-day Jabalpur).

Although he never converted to the religion, his conquests and patronage of Buddhism played an important role in the development of the Silk Road, and in the transmission of Mahayana Buddhism from Gandhara across the Karakoram range to China. Around 127 CE, he replaced Greek with Bactrian as the official language of administration in the empire.

Indian mathematics emerged in the Indian subcontinent from 1200 BCE until the end of the 18th century. In the classical period of Indian mathematics (400 CE to 1200 CE), important contributions were made by scholars like Aryabhata, Brahmagupta, Bhaskara II, Varāhamihira, and Madhava. The decimal number system in use today was first recorded in Indian mathematics. Indian mathematicians made early contributions to the study of the concept of zero as a number, negative numbers, arithmetic, and algebra. In addition, trigonometrywas further advanced in India, and, in particular, the modern definitions of sine and cosine were developed there. These mathematical concepts were transmitted to the Middle East, China, and Europe and led to further developments that now form the foundations of many areas of mathematics.

Ancient and medieval Indian mathematical works, all composed in Sanskrit, usually consisted of a section of sutras in which a set of rules or problems were stated with great economy in verse in order to aid memorization by a student. This was followed by a second section consisting of a prose commentary (sometimes multiple commentaries by different scholars) that explained the problem in more detail and provided justification for the solution. In the prose section, the form (and therefore its memorization) was not considered so important as the ideas involved. All mathematical works were orally transmitted until approximately 500 BCE; thereafter, they were transmitted both orally and in manuscript form. The oldest extant mathematical document produced on the Indian subcontinent is the birch bark Bakhshali Manuscript, discovered in 1881 in the village of Bakhshali, near Peshawar (modern day Pakistan) and is likely from the 7th century CE.

Al-Qaeda is a pan-Islamist militant organization led by Sunni Islamist jihadists who self-identify as a vanguard spearheading a global Islamist revolution to unite the Muslim world under a supra-national Islamic caliphate. Its membership is mostly composed of Arabs but also includes people from other ethnic groups. Al-Qaeda has mounted attacks on civilian and military targets of the U.S. and its allies; such as the 1998 US embassy bombings, the USS Cole bombing, and the September 11 attacks. It has been designated a terrorist organization by the United Nations and over two dozen countries around the world.

The organization was founded in a series of meetings held in Peshawar during 1988, attended by Abdullah Azzam, Osama bin Laden, Muhammad Atef, Ayman al-Zawahiri and other veterans of the Soviet–Afghan War. Building upon the networks of Maktab al-Khidamat, the founding members decided to create an organization named "Al-Qaeda" to serve as a "vanguard" for jihad. When Saddam Hussein invaded and occupied Kuwait in 1990, bin Laden offered to support Saudi Arabia by sending his Mujahideen fighters. His offer was rebuffed by the Saudi government, which instead sought the aid of the United States. The stationing of U.S. troops in the Arabian Peninsula prompted bin Laden to declare a jihad against both the rulers of Saudi Arabia – whom he denounced as murtadd (apostates) – and against the US. From 1992, al-Qaeda established its headquarters in Sudan until it was expelled in 1996. It then shifted its base to the Taliban-ruled Afghanistan and later expanded to other parts of the world, primarily in the Middle East and South Asia. In 1996 and 1998, bin Laden issued two fatāwā that demanded the withdrawal of U.S. troops from Saudi Arabia.
