West Pakistan was the western province of Pakistan between 1955 and 1970, covering the territory of present-day Pakistan. Its land borders were with Afghanistan, India and Iran, with a maritime border with Oman in the Gulf of Oman in the Arabian Sea.

Following its independence from British rule, the new Dominion of Pakistan was physically separated into two exclaves, with the western and eastern wings geographically separated from each other by India. The western wing of Pakistan comprised three governor's provinces (the North-West Frontier, West Punjab and Sind), one chief commissioner's province (Baluchistan) along with the Baluchistan States Union, several independent princely states (notably Bahawalpur, Chitral, Dir, Hunza, Khairpur and Swat), the Karachi Federal Capital Territory, and the autonomous tribal areas adjoining the North-West Frontier Province. The eastern wing of the new country—known as East Pakistan—comprised the single province of East Bengal (which included the former Assamese district of Sylhet and the Chittagong Hill Tracts).

West Pakistan was the politically dominant division of the Pakistani union, despite East Pakistan making up more than half of its population. The eastern wing also had a disproportionately small number of seats in the Constituent Assembly. This administrative inequality between the two wings, coupled with the major geographical distance between them, was believed to be delaying the adoption of a constitution for Pakistan. To aid in diminishing the differences between the two regions, the Pakistani government decided to reorganize the country into two distinct provinces under the One Unit policy announced by then Pakistani Prime Minister Chaudhry Muhammad Ali on 22 November 1954.

In 1970, the President of Pakistan General Yahya Khan enacted a series of territorial, constitutional and military reforms. These established the provincial assemblies, state parliament, as well as the current provisional borders of Pakistan's four official provinces. On 1 July 1970, West Pakistan was abolished under the Legal Framework Order of 1970, which dissolved the One Unit policy and restored the four provinces. This order had no effect on East Pakistan, which retained the geopolitical position established in 1955. The following year saw a major civil war erupt between West Pakistan and Bengali nationalists in East Pakistan. After a full-scale military intervention by India in support of the Bengali freedom fighters and after West Pakistan's subsequent defeat, the exclave of East Pakistan seceded from its union with the Islamic Republic of Pakistan as the new People's Republic of Bangladesh.

At the time of the state establishment in 1947, the founding fathers of Pakistan participated in the Boundary Commission conference. Headed by Cyril Radcliffe, the commission was tasked with negotiating the arrangement, area division, and future political set up of Pakistan and India.

Pakistan was formed from two distinct areas, separated by 1,600 kilometres (1,000 miles) of India. The western state was composed of three Governor's provinces (North-West Frontier, West-Punjab and Sindh Province), one Chief Commissioner's province (Baluchistan Province), the Baluchistan States Union, several other princely states (notably Bahawalpur, Chitral, Dir, Hunza, Khairpur and Swat), the Federal Capital Territory (around Karachi) and the tribal areas. The eastern wing of the new country – East Pakistan – formed the single province of East Bengal, including the former Assam district of Sylhet and the Hill Tracts.

West Pakistan experienced great problems related to the divisions, including ethnic and racial friction, lack of knowledge, and uncertainty of where to demarcate the permanent borders. East Pakistan, Balochistan, and the North-West Frontier Province experienced little difficulty, but Southern Pakistani Punjab faced considerable problems that had to be fixed. Former East Punjab was integrated with the Indian administration and millions of Punjabi Muslims were expelled to be replaced by a Sikh and Hindu population and vice versa. The communal violence spread to all over the Indian subcontinent. Economic rehabilitation efforts needing the attention of Pakistan's founding fathers further escalated the problems.

The division also divided the natural resources, industries, economic infrastructure, manpower, and military might, with India as the larger share owner. India retained 345 million in population (91%) to Pakistan's 35 million (9%). Land area was divided as 78% to India and 22% to Pakistan. Military forces were divided up with a ratio of 64% for India and 36% for Pakistan. Most of the military assets – such as weapons depots and military bases – were located inside India; facilities in Pakistan were mostly obsolete, and they had a dangerously low ammunition reserve of only one week. Four divisions were raised in West Pakistan, whilst one division was raised in East Pakistan.

From the time of its establishment, the State of Pakistan had the vision of a federal parliamentary democratic republic form of government. With the founding fathers remaining in West Pakistan, Liaquat Ali Khan was appointed the country's first prime minister, with Mohammad Ali Jinnah as Governor-General. West Pakistan claimed the exclusive mandate over all of Pakistan, with the majority of the Pakistan Movement's leading figures in West Pakistan. In 1949, the Constituent Assembly passed the Objectives Resolution and the Annex to the Constitution of Pakistan, paving the road to a Westernized federal parliamentary republic. The work on parliamentary reforms was constituted by the constituent assembly the year after, in 1950.

The western section of Pakistan dominated the politics of the new country. Although East Pakistan had over half of the population, it had a disproportionately small number of seats in the Constituent Assembly. This inequality of the two wings and the geographical distance between them was believed to be holding up the adoption of a new constitution. To diminish the differences between the two regions, the government decided to reorganise the country into two distinct provinces.

Under the One Unit policy announced by Prime Minister Muhammad Ali Bogra on 22 November 1954, the four provinces and territories of western Pakistan were integrated into one unit to mirror the single province in the east. The state of West Pakistan was established by the merger of the provinces, states, and tribal areas of West Pakistan. The province was composed of twelve divisions and the provincial capital was established at Karachi. Later the state capital moved to Lahore, and it was finally established in Islamabad in 1965. The province of East Bengal was renamed East Pakistan with the provincial state capital at Dhaka (Dacca).

Clashes between West Pakistan and East Pakistan soon erupted, further destabilising the entire country. The two states had different political ideologies and different lingual cultural aspect. West Pakistan had been founded on the main basis of a parliamentary democracy (and had a parliamentary republic form of government since 1947), with Islam as its state religion. In contrast, East Pakistan had been a socialist state since the 1954 elections, with state secularism proclaimed. West Pakistan sided with the United States and her NATO allies, whilst East Pakistan remained sympathetic to the Soviet Union and her Eastern Bloc. Pakistan's 1956 constitution validated the parliamentary form of government, with Islam as state religion and Urdu, English and Bengali as state languages. The 1956 constitution also established the Parliament of Pakistan as well as the Supreme Court of Pakistan.

Ethnic and religious violence in Lahore, which began in 1953, spread all over the country. Muhammad Ali Bogra, prime minister of Pakistan, declared martial law in Lahore to curb the violence. This inter-communal violence soon spread to India, and a regional conflict put West Pakistan and India in a war-threatening situation. The prime ministers of Pakistan and India held an emergency meeting in Lahore.

From 1947 to 1959, the government was only partially stable. Seven prime ministers, four governors-general, and one president were forcefully removed either by constitutional coup or by military coup. The One Unit program was met with harsh opposition, civil unrest, and political disturbance. Support for the Muslim League and Pakistan Socialist Party in the upcoming elections threatened Pakistan's technocracy. The Muslim League and Socialist Party gained momentum after the League's defeat in the 1954 elections, and the Socialist Party were challenging for the constituencies of the President Iskandar Mirza's Republican Party. Relations with the United States deteriorated, with the US assessing that democracy in both states was failing.

A US-backed military coup d'état was launched in 1958 by the Pakistan Army command. The Urdu-speaking class and the Bengali nation were forcefully removed from the affairs of West Pakistan. With the imposition of martial law led by then-Army Commander-in-Chief General Ayub Khan, the state capital was moved from Karachi to Army Generals Combatant Headquarters (The GHQ) at Rawalpindi in 1959, whilst the federal legislature was moved to Dacca. In 1963, Rawalpindi had become ineffective as a federal capital; a new city was planned and constructed, finally completing in 1965. In 1965, the state capital was finally re-located in Islamabad.

On contrary perception, the provinces did not benefit from economic progress, but the One Unit program strengthened the central government. In West Pakistan, the four provinces also struggled hard for the abolition of One Unit which caused injustices to them as it was imposed on them.

The provisional powerful committees pressured the central government through the means of civil disobedience, violence on street, raising slogans against the martial law, and attacks on government machines such as police forces. For several weeks, the four provinces worked together and guided the "One Unit Dissolution Committee", towards resolving all outstanding issues in time set by the Yahya government. Finally, the committee's plan went into effect on 1 July 1970, when West Pakistan's "One Unit" was dissolved, and all power was transferred to the provinces of Balochistan, the North West Frontier Province, Punjab and Sindh.

In the 1970 general elections (held in December 1970), the Bengali Awami League under Mujibur Rahman won an overall majority of seats in Parliament and all but 2 of the 162 seats allocated to East Pakistan. The Awami League advocated greater autonomy for East Pakistan but the military government did not permit Mujib-ur-Rahman to form a government.

East Pakistan became the independent state of Bangladesh on 16 December 1971. The term West Pakistan became redundant.

The total population of the region that composes West Pakistan was approximately 29.6 million as per the 1941 census.

According to the 1961 census, the total population of Pakistan was 93 million, with 42.8 million residing in West Pakistan and 50 million residing in East Pakistan. East Pakistan hence made up around 55% of Undivided Pakistan's population whilst remaining 45% was in West Pakistan. West Pakistan also had a marginally faster growing population than East Pakistan.

The literacy rate in Pakistan was 19.2%, in which East Pakistan had a literacy rate of 21.5% while West Pakistan had a literacy rate of 16.9%.

The major ethnic groups of West Pakistan was made up of Punjabis (who made up the overall majority of the province), Pashtuns, Sindhis, Muhajirs, and Balochis.

During British India's partition, it was estimated that 15 million were displaced, and nearly more than 2 million consisting of Hindus, Muslims and Sikhs were killed in the deadly riots. During the period between 1947 and 1950, 8.6 million Muslims had moved to specially Pakistan's West Punjab region and about 6.7 million Hindus and Sikhs had gone the other way to India's East Punjab region and thus changing the demography of Pakistan drastically and resulting in overwhelming Muslim majority to this region.

With the exception of the Federally Administered Tribal Areas, all administrative divisions in the region that would compose West Pakistan after independence collected religious data, with a combined total population of 27,266,001, for an overall response rate of 92 percent. Similar to the contemporary era, where censuses do not collect religious data in Azad Jammu and Kashmir and Gilgit–Baltistan, the total number of responses for religion is slightly smaller than the total population, as detailed in the table breakdown below.

According to the 1961 census, in West Pakistan, Muslims made up 97.2% of the population, Christians 1.4%, and the remaining 1.4% belonging to other religions.

West Pakistan went through many political changes, and had a multiple political party system. West Pakistan's political system consisted of the popular influential Left-wing sphere against elite Right-wing circles.

Since independence, Pakistan had been a federal parliamentary constitutional monarchy (even as of today, the parliamentary system is the official form of government of Pakistan) with a Prime minister as the head of the government and a Monarch as the head of state in a ceremonial office.

The 1956 Constitution provided the country with Parliamentary form of Government and the office of President was inaugurated the same year. The career civil service officer Major-General (retired) Iskander Mirza became the country's first President, but the system did not evolve for more than the three years, when Mirza imposed the martial law in 1958. Mirza appointed army commander-in-chief General Ayub Khan as Chief Martial Law Administrator; he later turned his back on the President and exiled him to Great Britain after the military government was installed.

The Supreme Court of Pakistan was a judicial authority, a power broker in country's politics that played a major role in minimising the role of parliament. The Supreme Court was moved to Islamabad in 1965 and Chief Justice Alvin Robert Cornelius re-located the entire judicial arbiter, personnel and high-profile cases in Islamabad. The Supreme Court building is one of the most attractive places in Islamabad, yet the most largely beautiful building in the state capital.

This provisional parliament had no lasting effects of West Pakistan's affairs but it was a ceremonial legislature where the lawmakers would gather around to discuss non-political matters. In 1965, the legislative parliament was moved to Islamabad after Ayub Khan built a massive capitol. The assembly was renamed as the Parliament of Pakistan and staffed only with technocrats.

The office of Governor of West Pakistan was a largely ceremonial position but later Governors wielded some executive powers as well. The first Governor was Mushtaq Ahmed Gurmani, who was also the last Governor of West Punjab. Ayub Khan abolished the Governor's office and instead established the Martial Law Administrator of West Pakistan (MLA West).

The office Chief Minister of West Pakistan was the chief executive of the state and the leader of the largest party in the provincial assembly. The first Chief Minister was Abdul Jabbar Khan who had served twice as Chief Minister of the Khyber Pakhtunkhwa Province prior to independence. The office of Chief Minister was abolished in 1958 when Ayub Khan took over the administration of West Pakistan.

The twelve divisions of West Pakistan province were Bahawalpur, Dera Ismail Khan, Hyderabad, Kalat, Khairpur, Lahore, Malakand, Multan, Peshawar, Quetta, Rawalpindi, and Sargodha; all named after their capitals except the capital of Malakand was Saidu, and Rawalpindi was administered from Islamabad. The province also incorporated the former Omani enclave of Gwadar following its purchase in 1958, and the former Federal Capital Territory (Karachi) in 1958; the latter in 1960 forming a new division in its own right.

In 1970, the Martial Law Office was dissolved by General Yahya Khan who disestablished the state of West Pakistan. On 1 July 1970, the provisional assemblies of Balochistan, Punjab, Sindh, and Khyber Pakhtunkhwa, Office of Prime minister, and much of the civil institutions were revived and re-established by the decree signed by Yahya Khan. The four provinces and four administrative units retained their current status and local governments were constitutionally established in 1970 to manage and administer the provisional autonomy given to the provinces in 1970.

West Pakistan was extremely diverse in terms of geography, climate, and variety of wildlife. North-Western West Pakistan was mountainous, Punjab and Sindh were semi-arid, and the Baluchistan region in particular was predominantly desert. West Pakistan had a varied relief, consisting as it does of plains, plateaux and mountains watered by the Indus River and its tributaries. Climatically, West Pakistan had a continental type of climate without extensive rainfall. Due to its low rainfall, the main crops of West Pakistan were wheat, millets, and cotton and any crop that did not require much water.

West Pakistan Province Comprises in 12 divisions, 45 districts and 6 agencies.

During West Pakistan's conflict with India, East Pakistan's military government remained silent and did not send any troops to exert pressure on Eastern India. West Pakistan accused East Pakistan of not taking any action, and their inaction caused West Pakistani resentment against East Pakistan's government. In fact, the Indian Air Force Eastern Air Command attacked East Pakistan's Air Force. However, East Pakistan was defended only by the under-strength 14th Infantry Division and sixteen fighter jets; no tanks and no navy were established in East Pakistan.

The One Unit policy was regarded as a rational administrative reform that would reduce expenditure and eliminate provincial prejudices. West Pakistan formed a seemingly homogeneous block, but in reality it comprised marked linguistic and ethnic distinctions. The four provinces did not quite fit official definitions of a single nation.

The Sindhi and Urdu-speaking class in Sindh Province revolted against the One Unit policy. The violence spread to Balochistan Province, Khyber-Pakhtunkhwa and Punjab Province. The One Unit policy was a failure in West Pakistan, and its survival was seen as improbable. However, with the military coup of 1958, trouble loomed for the province when the office of Chief Minister was abolished and the President took over executive powers for West Pakistan.

Due to West Pakistan's close relations with the United States and the capitalist states, the influence of socialism had far more deeper roots in the West Pakistan population. The population favoured socialism but never allied with communism. The Pakistan Socialist Party had previously lost support due to its anti-Pakistan clauses during the time of the pre-independence movement. However, despite initiatives to improve the population during the Ayub Khan's government, the poor masses did not enjoy the benefits and reforms that were enjoyed by the middle and gentry classes of Pakistan.

After the Indo-Pakistani war of 1965, the cultural revolution, resentment, hostility towards the government began to arise when the population felt that "Kashmir cause" was betrayed by President Ayub Khan. Problems further mounted after Foreign minister Zulfikar Ali Bhutto was sacked and vowed to take a revenge. After gathering and uniting the scattered democratic socialist and Marxist masses, Bhutto founded the Pakistan Peoples Party in 1967. The socialists tapped a wave of antipathy against the United States-allied president. The socialists integrated in poor and urban provinces of West Pakistan, educating people to cast their vote for their better future, and the importance of democracy was widely sensed in the entire country. The socialists, under Bhutto's guidance and leadership, played a vital role in managing labour strikes and civil disobedience to challenge Khan's authority. The military government responded fiercely after arresting the senior socialists' leadership, notably Bhutto, Mubashir Hassan, and Malick Mirage. This sparked gruesome violence in West Pakistan, thereby increasing pressure on Khan that he was unable to endure. Khan called for a Round Table Conference in Rawalpindi, but socialists led by Bhutto refused to accept Ayub's continuation in office and rejected the 6 Point Movement for regional autonomy put forth in 1966 by East Pakistani politician Sheikh Mujibur Rahman.

In 1969, Khan handed over power to Army Chief of Staff General Yahya Khan, who promised to hold elections within two years. Meantime, Bhutto extensively worked to gather and unite the country's left-wing organisations, which, under Bhutto's leadership, participated with full force and became vital players in the country's politics.

The long border between West Pakistan and Afghanistan was uneasy. This is due in part to the independent Pashtun tribes that inhabit the area. In addition, the physical boundary is uncertain: the 1893 Durand Line was used by West Pakistan to mark the border between the two countries, but Afghanistan has never recognised that frontier.

In 1955, diplomatic relations were severed with the ransacking of Pakistan's embassy. In 1961, the Pakistan Armed Forces and local Pashtun tribes suppressed an Afghan invasion in the Bajaur region of Pakistan.

West Pakistan had hostile relations with India, primarily due to aftermath of the 1947 independence from the British Empire and the issue of Kashmir.

In 1965, "Operation Gibraltar" had long-ranging negative effects, outside and inside the country. Foreign minister Zulfikar Ali Bhutto and Defence minister Vice-Admiral Afzal Rahman Khan approached President Ayub Khan for approval of a covert operation to infiltrate Indian-administered Kashmir using airborne troops from the Pakistan Army (Special Service Group) and Pakistan Air Force (Special Service Wing). During nights in August 1965, airborne troops parachuted into Indian Kashmir whilst ground assault began by Pakistan Army's troops. The airborne troops managed to occupy much of Indian-administered Kashmir and were only 10 kilometres (6 mi) from Srinagar, but this was the closest Pakistani troops ever got to capturing the city. In September 1965, India launched a counter-attack and the airborne troops were pushed back to what is today Azad Kashmir. Indian forces also crossed the ceasefire line into Azad Kashmir and captured the Haji Pir pass.

Subsequently, Pakistan launched Operation Grand Slam, which gained significant momentum. Grand Slam was aborted after India launched an all out attack on West Pakistan, for which Pakistani troops had to be diverted. The Soviet Union intervened in the conflict in September 1965 (for fear of escalation), and the month–long war ended with no permanent territorial changes. West Pakistan and India signed the Tashkent Declaration in January 1966, but the ceasefire was criticised both in India and Pakistan, and public resentment against each other grew. In West Pakistan, Ayub Khan deposed Bhutto as his Foreign minister, and Vice-Admiral Khan blamed Bhutto for the operation's failure. As an aftermath, Bhutto tapped into an anti-Ayub Khan movement and kicked off a storm of civil disobedience. Protests and spontaneous demonstrations broke out around the country, and Ayub Khan lost the control. In 1967, another martial law was imposed by another Army Commander-in-Chief, General Yahya Khan, who designated himself as the Chief Martial Law Administrator.

West Pakistan had positive relations with the People's Republic of China, with whom it shared a small northern border.

In 1950, Pakistan was among the first countries to end official diplomatic relations with the Taiwanese Republic of China and recognise the PRC. After that, both countries maintained an extremely close and supportive relationship. The PRC provided economic, military and technical assistance to Pakistan during the Cold War, and the two countries considered each other to be close strategic allies.

Relations varied from cool to extremely strained between West Pakistan and the Soviet Union. This was during the Cold War, and Pakistan's close ties with the United States came at the expense of relations with the Soviets.

Soviet-Pakistan relations were further eroded during the 1960 U-2 incident, when the Soviets shot down a US spyplane; Army Chief-of-Staff Ayub Khan had given the US permission to fly out of Peshawar Air Station on reconnaissance and covert surveillance missions over the Soviet Union.

The USSR backed India during the Indo-Pakistani War of 1971. The Soviets were the biggest supplier of military hardware to India at that time.

The United States was one of the first nations to establish relations with Pakistan upon its independence.

Pakistan was allied with the US during the Cold War against the USSR. Pakistan was an integral member of the Southeast Asia Treaty Organization (SEATO) and the Central Treaty Organization (CENTO), both alliances opposed to the Soviet Union and communism.

A major factor in Pakistan's decision to ally with the West was their urgent need for aid. In the years that followed, the US supplied extensive economic, scientific, and military assistance to Pakistan.

This close relationship continued through Pakistan's years of democracy and military rule. Relations only soured after West Pakistan had dissolved into Pakistan, when the left-oriented Pakistan Peoples Party came to power in 1971.
