Gilgit Agency in the context of "North-West Frontier Province"

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.

Baltistan (English: /ˌbɔːltɪˈstɑːn/, Urdu: [bəlt̪ɪst̪aːn]); also known as Baltiyul or Little Tibet, is a mountainous region in the Pakistani-administered territory of Gilgit-Baltistan and constitutes a northern portion of the larger Kashmir region that has been the subject of a dispute between India and Pakistan since 1947. It is located near the Karakoram (south of K2) and borders Gilgit to the west, China's Xinjiang to the north, Indian-administered Ladakh to the southeast, and the Indian-administered Kashmir Valley to the southwest. The average altitude of the region is over 3,350 metres (10,990 ft). Baltistan is largely administered under the Baltistan Division.

Prior to the partition of British India in 1947, Baltistan was part of the princely state of Jammu and Kashmir, having been conquered by Gulab Singh's armies in 1840. Baltistan and Ladakh were administered jointly under one wazarat (district) of the state. The region retained its identity in this setup as the Skardu tehsil, with Kargil and Leh being the other two tehsils of the district. After Hari Singh, the last maharaja of Jammu and Kashmir, acceded to the Dominion of India in 1947, his local governor in Gilgit was overthrown by the Gilgit Scouts, who then took the entire region for Pakistan during the Indo-Pakistani War of 1947–1948. The Gilgit Agency and Skardu tehsil, as well as a portion of Kargil tehsil, have since been under Pakistani governance while the Kashmir Valley as well as Leh tehsil and most of the Kargil tehsil remain under Indian governance. The Chorbat Valley, geographically in the Baltistan region, was de-facto partitioned when its four villages (with one Bogdang already under Indian control since 1947) were captured by India during the Indo-Pakistani War of 1971, and were incorporated into the erstwhile state of Jammu and Kashmir (now in Ladakh).

Chitral or Chitrāl (Persian: چترال) was a princely state in alliance with British India until 1947, then a princely state of Pakistan until 1972. The area of the state now forms the Upper and Lower Chitral Districts of the Khyber Pakhtunkhwa, Pakistan.

During the reign of Mehtar Aman ul-Mulk, the dynasty's sway extended from Asmar in the Kunar Valley of Afghanistan to Punial in the Gilgit Valley. The entire region that now forms the Chitral District was a fully independent monarchy until 1885, when the British negotiated a subsidiary alliance with its hereditary ruler, the Mehtar, under which Chitral became a princely state, still sovereign but subject to the suzerainty of the British Indian Empire. In 1895 the British agent in Gilgit, Sir George Scott Robertson was besieged in Chitral Fort for 48 days, and was finally relieved by two British Forces, one marching from Gilgit and the other from Nowshera. After 1895, the British hold became stronger, but the internal administration remained in the hand of the Mehtar. In 1947 India was partitioned and Chitral opted to accede to Pakistan. After accession, it finally became an administrative district of Pakistan in 1972.

Hunza (Persian: هنزه, Urdu: ہنزہ), also known as Kanjut (Persian: کانجوت; Urdu: کنجوت), was a Burusho princely state in the present-day Gilgit Baltistan region of Pakistan. Although under the suzerainty of the Jammu and Kashmir, it was not a part of it and had status of a separate state. Initially, it functioned as a principality and subsequently became a princely state under a subsidiary alliance with the British India starting in 1892 and continuing until August 1947. For a brief period of three months, it remained unaligned after gaining independence, and then from November 1947 until 1974, it retained its status as a princely state within Pakistan.

The princely state bordered the Gilgit Agency to the south, the former princely state of Nagar to the east, Xinjiang, China, to the northeast and Afghanistan to the northwest. The state's capital was Baltit (also known as Karimabad). The former princely state of Hunza is now the Hunza District in the Gilgit Baltistan region of Pakistan.
