Gwadar Purchase
The Gwadar Purchase (, lit. 'Acquisition of Gwadar') was the acquisition of the territory of Gwadar by the Dominion of Pakistan from the Sultanate of Oman in 1958. Pakistan was able to acquire  of land on the coast of Balochistan for around Rs 5.5 billion (or 2 billion US dollars today), paid mostly by Aga Khan IV. The deal was made with the efforts of Prime Minister of Pakistan Feroz Khan Noon and Said bin Taimur, the Sultan of Oman, and Pakistan was able to purchase the land on 8 September 1958, and it officially became a part of Pakistan on 8 December 1958. Background 
In the year 1783, the Khan of Kalat, Mir Noori Naseer Khan Baloch, granted Gwadar to Taimur Sultan, the vanquished leader of Muscat, who was entrusted with its governance on behalf of the Khan. Despite Taimur Sultan's eventual recovery of power in Muscat, the Omani administration continued to hold sway over Gwadar through the appointment of local governors. In the year 1797, Saiad Sultan assumed the leadership of Muscat, but he did not relinquish control of the Gwadar enclave to Kalat. This resulted in a dispute between the Sultan's descendants and the Khan of Kalat regarding the governance of Gwadar, which led to British involvement in the matter. Eventually, the British brought telegraph lines to the town. Having secured concessions from the Sultan for the utilization of the region, the British assisted Muscat in maintaining control over Gwadar. Between 1863 and 1879, Gwadar served as the center of operations for a British Assistant Political Agent. The town was visited fortnightly by steamers belonging to the British India Steamship Navigation Company and featured a joint Post and Telegraph Office. At the time of Pakistan's independence in 1947, Gwadar remained under Omani authority. Nevertheless, Pakistan started to indicate interest in Gwadar after it acquired control of various Baloch territories, including the Chief Commissioner's Province of British Baluchistan, as well as the states of Kharan, Makran, Lasbela and Kalat. Over the months following independence, Pakistan absorbed these regions into its territory. In 1954, Pakistan enlisted the services of the United States Geological Survey (USGS) to conduct a survey of its coastline. Based on the survey's findings, Gwadar was deemed a viable location for the development of a new deep-water port. Negotiations 
Worth Condrick, the USGS surveyor, ascertained that Gwadar was an appropriate site for a deep-sea port due to its unique hammerhead-shaped peninsula. Upon receiving this information and with the backing of the local inhabitants, the Pakistani government made a formal request to the Sultan of Oman and Muscat to permit Gwadar to join Pakistan. The two countries negotiated over this matter for a period of four years. Following Pakistan's expression of interest in acquiring Gwadar, the country also requested the aid of the UK government in arranging a trade agreement between Oman and Pakistan. Nevertheless, the UK initially discouraged this proposal and only became involved in the negotiations in 1958. Ultimately, the UK helped to facilitate the talks between the two parties. Prime Minister of Pakistan Feroz Khan Noon and his wife Viqar-un-Nisa Noon entered negotiations with the Sultan of Oman, Said bin Taimur in 1958. During this time, the Sultan of Oman agreed to hand Gwadar over to Pakistan for Rs. 5.5 billion, which was paid to by the 49th Imam of Nizari Ismailis, Aga Khan IV. As per the agreement, in the event that oil was discovered in Gwadar in commercially viable amounts, the Pakistani government would have to pay a percentage of the total revenue to the Sultan. The deal also included provisions for the residents of Gwadar to retain their Omani citizenship without jeopardizing their rights as Pakistani citizens, the recruitment of Gwadar residents into the Sultan's Armed Forces, the opportunity for military personnel to receive training in Pakistani technical schools, the extradition of deserters to Oman, and the unrestricted export of rice to Oman at regular trade rates. Acquisition by Pakistan 
On 7 September 1958, Prime Minister of Pakistan Feroz Khan Noon announced the following on Radio Pakistan:"The Government of Pakistan has issued a communiqué stating that the administration of the Port of Gwadar and its hinterland, which had been in the possession of His Highness the Sultan of Muscat and Oman since 1784, was today taken over by Pakistan with full sovereign rights. The people of Gwadar have joined the people of Pakistan and the whole of Gwadar now forms part of the Islamic Republic of Pakistan. I know that the people all over Pakistan, including those residing in Gwadar, have received this announcement with feelings of great joy. I welcome the residents of Gwadar into the Republic of Pakistan and I would like to assure them that they will enjoy equal rights and privileges along with all other Pakistan nationals irrespective of considerations of religion, caste or creed. They will have their full share in the glory and prosperity of the Republic to which they now belong. The residents of Gwadar, most of who are members of the brave Balochi community, have close racial and cultural links with the people of Pakistan and joining the Republic of Pakistan represents the natural culmination of their political aspirations. I should like to take this opportunity to thank, on behalf of the people and Government of Pakistan, Her Majesty’s Government in the United Kingdom for their assistance and help in bringing to a successful conclusion our negotiations with His Highness the Sultan of Muscat and Oman for the transfer of his rights in Gwadar." Post-acquisition status 
After the formal acquisition of Gwadar by Pakistan, the territory was included as a part of West Pakistan and was designated as a Tehsil of the Makran district. Later on, the Makran District was elevated to a division, and on 1 July 1977, it was divided into three districts: Turbat (renamed Kech since 1994–95), Panjgur, and Gwadar. This arrangement remains in place to this day. Presently, Gwadar comprises four Teshils, namely Jiwani, Pasni, and Ormara, and Gwadar itself. See also
