Khyber Pakhtunkhwa replaces North-West Frontier Province
Khyber Pakhtunkhwa (; Pashto: خېبر پښتونخوا; Hindko, Urdu: خیبر پختونخوا, pronounced [ˈxɛːbəɾ paxˈtuːnxwɑː] (listen)), commonly abbreviated as KP or KPK, 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 the Pakistani provinces of Balochistan to the south, Punjab to the south-east, the territory of Gilgit-Baltistan to the north and north-east, Islamabad Capital Territory to the east and Azad Kashmir to the north-east. It shares an international border with Afghanistan to the west. Khyber Pakhtunkhwa has a varied landscape ranging from rugged mountain ranges, valleys, plains surrounded by hills, undulating submontane areas and dense agricultural farms.
While it is the third-largest Pakistani province in terms of both its population and its economy, it is geographically the smallest. The province is home to 17.9 percent of Pakistan's total population. The province is multiethnic, with the main ethnic groups being the Pashtuns, Hindkowans, Saraikis, and Chitralis.Once a stronghold of Buddhism, Khyber Pakhtunkhwa is the site of the ancient region of Gandhara, including the ruins of the Gandharan capital of Pushkalavati (located near modern-day Charsadda). The region's history is characterized by frequent invasions by various empires, largely due to its geographical proximity to the historically important Khyber Pass.Although it is colloquially known by a variety of other names, the name "Khyber Pakhtunkhwa" was brought into effect for the North-West Frontier Province in April 2010, following the passing of the 18th Constitutional Amendment. On 24 May 2018, the National Assembly of Pakistan voted in favour of the 25th Constitutional Amendment, which merged the FATA as well as the Provincially Administered Tribal Areas into Khyber Pakhtunkhwa. The Provincial Assembly of Khyber Pakhtunkhwa subsequently approved the bill on 28 May 2018; it was signed into law on 31 May by erstwhile Pakistani president Mamnoon Hussain, which officially completed the administrative merger process.Etymology
Khyber Pakhtunkhwa  means the "Khyber side of the land of the Pashtuns," where the word Pakhtunkhwa means "Land of the Pashtuns", while according to some scholars, it refers to "Pashtun culture and society".When the British established it as a province, they called it "North West Frontier Province" (abbreviated as NWFP) until 2010 due to its relative location being in the northwest of their Indian Empire. After the creation of Pakistan, Pakistan continued with this name but a Pashtun political party, Awami National Party based in the province demanded that the province name be changed to "Pakhtunkhwa". Their logic behind that demand was that Punjabi people, Sindhi people and Baloch people have their provinces named after their ethnicities but that is not the case for Pashtun people.Pakistan Muslim League (N), the largest opposition party at the time was ready to change the province's name by supporting the ruling Pakistan Peoples Party and ANP, in a constitutional amendment but wanted to name the province something other than which does not carry only the Pashtun identity in it as they argued that there were other minor communities living in the province especially the Hazarewals of the Hazara region who spoke Hindko thus the word Khyber was introduced with the name because it is the name of a major pass which connects Pakistan to Afghanistan.British Raj
British East India Company defeated the Sikhs during the Second Anglo-Sikh War in 1849, and incorporated small parts of the region into the Province of Punjab. While Peshawar was the site of a small revolt against British during the Mutiny of 1857, local Pashtun tribes throughout the region generally remained neutral or supportive of the British as they detested the Sikhs, in contrast to other parts of British India which rose up in revolt against the British. However, British control of parts of the region was routinely challenged by Wazir tribesmen in Waziristan and other Pashtun tribes, who resisted any foreign occupation until Pakistan was created. By the late 19th century, the official boundaries of Khyber Pakhtunkhwa region still had not been defined as the region was still claimed by the Kingdom of Afghanistan. It was only in 1893 The British demarcated the boundary with Afghanistan under a treaty agreed to by the Afghan king, Abdur Rahman Khan, following the Second Anglo-Afghan War. Several princely states within the boundaries of the region were allowed to maintain their autonomy under the terms of maintaining friendly ties with the British. As the British war effort during World War One demanded the reallocation of resources from British India to the European war fronts, some tribesmen from Afghanistan crossed the Durand Line in 1917 to attack British posts in an attempt to gain territory and weaken the legitimacy of the border. The validity of the Durand Line, however, was re-affirmed in 1919 by the Afghan government with the signing of the Treaty of Rawalpindi, which ended the Third Anglo-Afghan War – a war in which Waziri tribesmen allied themselves with the forces of Afghanistan's King Amanullah in their resistance to British rule. The Wazirs and other tribes, taking advantage of instability on the frontier, continued to resist British occupation until 1920 – even after Afghanistan had signed a peace treaty with the British.
British campaigns to subdue tribesmen along the Durand Line, as well as three Anglo-Afghan wars, made travel between Afghanistan and the densely populated heartlands of Khyber Pakhtunkhwa increasingly difficult. The two regions were largely isolated from one another from the start of the Second Anglo-Afghan War in 1878 until the start of World War II in 1939 when conflict along the Afghan frontier largely dissipated. Concurrently, the British continued their large public works projects in the region, and extended the Great Indian Peninsula Railway into the region, which connected the modern Khyber Pakhtunkhwa region to the plains of India to the east. Other projects, such as the Attock Bridge, Islamia College University, Khyber Railway, and establishment of cantonments in Peshawar, Kohat, Mardan, and Nowshera further cemented British rule in the region. In 1901, the British carved out the northwest portions of Punjab Province to create the Northwest Frontier Province (NWFP), which was renamed "Khyber Pakhtunkhwa" in 2010.During this period, North-West Frontier Province was a "scene of repeated outrages on Hindus." During the independence period there was a Congress-led ministry in the province, which was led by secular Pashtun leaders, including Bacha Khan, who preferred joining India instead of Pakistan. The secular Pashtun leadership was also of the view that if joining India was not an option then they should espouse the cause of an independent ethnic Pashtun state rather than Pakistan. In June 1947, Mirzali Khan, Bacha Khan, and other Khudai Khidmatgars declared the Bannu Resolution, demanding that the Pashtuns be given a choice to have an independent state of Pashtunistan composing all Pashtun majority territories of British India, instead of being made to join the new state of Pakistan. However, the British Raj refused to comply with the demand of this resolution, as their departure from the region required regions under their control to choose either to join India or Pakistan, with no third option. By 1947 Pashtun nationalists were advocating for a united India, and no prominent voices advocated for a union with Afghanistan.The secular stance of Bacha Khan had driven a wedge between the ulama of the otherwise pro-Congress (and pro-Indian unity) Jamiat Ulema Hind (JUH) and Bacha Khan's Khudai Khidmatgars.
