Partition of British India in the context of "Mass migration"

Bangladesh, officially the People's Republic of Bangladesh, is a country in South Asia. It is the eighth-most populous country in the world and among the most densely populated with a population of over 171 million within an area of 148,460 square kilometres (57,320 sq mi). Bangladesh shares land borders with India to the north, west, and east, and Myanmar to the southeast. It has a coastline along the Bay of Bengal to its south and is separated from Bhutan and Nepal by the Siliguri Corridor, and from China by the Indian state of Sikkim to its north. Dhaka, the capital and largest city, is the nation's political, financial, and cultural centre. Chittagong is the second-largest city and the busiest port of the country.

The territory of modern Bangladesh was a stronghold of many Hindu and Buddhist dynasties in ancient history. Following the Muslim conquest in 1204, the region saw Sultanate and Mughal rule. During the Mughal period, particularly under the Bengal Subah, the region emerged as one of the most prosperous and commercially active parts of the world, known for its thriving textile industry and agricultural productivity. The Battle of Plassey in 1757 marked the beginning of British colonial rule for the following two centuries. In the aftermath of the Partition of India in 1947, East Bengal became the eastern and most populous wing of the newly formed Dominion of Pakistan and was later renamed to East Pakistan.

Lahore is the capital and largest city of the Pakistani province of Punjab. It is the second-largest city in Pakistan, after Karachi, and 27th largest in the world, with a population of over 14 million. Lahore is one of Pakistan's major industrial, educational and economic hubs. It has been the historic capital and cultural centre of the wider Punjab region, and is one of Pakistan's most socially liberal, progressive, and cosmopolitan cities.

Lahore's origin dates back to antiquity. The city has been inhabited for around two millennia, although it rose to prominence in the late 10th century with the establishment of the Walled City, its fortified interior. Lahore served as the capital of several empires during the mediaeval era, including the Hindu Shahis, Ghaznavid Empire and Delhi Sultanate. It reached the height of its splendour under the Mughal Empire between the late 16th and early 18th centuries, being its capital city for many years. During this period, it was one of the largest cities in the world. The city was captured by the forces of the Afsharid ruler Nader Shah in 1739. Although the Mughal authority was re-established, it fell into a period of decay while being contested among the Afghans and the Sikhs between 1748 and 1798, eventually becoming capital of the Sikh Empire in the early 19th century. Lahore was annexed to the British Raj in 1849 and became the capital of British Punjab. Lahore was central to the independence movements of British India, with the city being the site of both the Declaration of Indian Independence and the resolution calling for the establishment of Pakistan. It experienced some of the worst rioting during the partition of British India preceding Pakistan's establishment. Following the success of the Pakistan Movement and the subsequent partition in 1947, Lahore was declared the capital of Pakistan's Punjab province.

Peshawar is the capital and largest city of the Pakistani province of Khyber Pakhtunkhwa. It is the eighth-most populous Pakistani city, with a population of over 1.9 million. It is situated in the north-west of the country, lying in the Valley of Peshawar, a broad area situated east of the Khyber Pass.

Peshawar's recorded history dates back to at least sixth century BC, making it one of the oldest continuously inhabited cities in South Asia. One of the principal cities of the ancient Gandhara, Peshawar served as the capital of the Kushan Empire during the rule of Kanishka the Great, in the second century CE. A variety of Muslim empires ruled the city following the conquest of Peshawar by the Ghaznavids from the Hindu Shahis, in 1001 CE. It was an important trading centre in the Mughal Empire, later serving as the winter capital of the Durrani Empire from 1776 until the capture of the city by the Sikh Empire in 1823. In 1849, the city was captured by the East India Company and subsequently became part of British Raj. In 1901, Peshawar became capital of the North-West Frontier Province after it was created from the northwestern districts of Punjab Province. Following the Partition of British India it became part of Pakistan, in 1947.

Pashtunistan (Pashto: پښتونستان, lit. 'land of the Pashtuns') or Pakhtunistan is a historical region on the crossroads of Central and South Asia, located on the Iranian Plateau, inhabited by the Pashtun people of southern and eastern Afghanistan and northwestern Pakistan, wherein Pashtun culture, the Pashto language, and identity have been based. Alternative names historically used for the region include Pashtūnkhwā or Pakhtūnkhwā (پښتونخوا), or simply the Pashtun Belt.

During British rule in India in 1893, Mortimer Durand drew the Durand Line, fixing the limits of the spheres of influence between the Emirate of Afghanistan and British India during the Great Game and leaving about half of historical Pashtun territory under British colonial rule; after the partition of British India, the Durand Line now forms the internationally recognized border between Afghanistan and Pakistan. The traditional Pashtun homeland stretches roughly from the areas south of the Amu River in Afghanistan to the areas west of the Indus River in Pakistan; it predominantly comprises the southwestern, eastern and some northern and western districts of Afghanistan, as well as most of Khyber Pakhtunkhwa and northern Balochistan in Pakistan. The region is bordered by Punjab and Hazara to the east, Balochistan to the south, Kohistan and Chitral to the north, and Hazarajat and Tajik-inhabited territory to the west.

Qawwali is a form of Sufi Islamic devotional singing originating in South Asia. Originally performed at Sufi shrines throughout the Indian subcontinent, it is famous throughout Pakistan, India, Bangladesh and Afghanistan and has also gained mainstream popularity and an international audience as of the late 20th century.

While hereditary performers continue to perform Qawwali music in traditional and devotional contexts, Qawwali has received international exposure through the work of Nusrat Fateh Ali Khan, Aziz Mian and Sabri Brothers largely due to several releases on the Real World label, followed by live appearances at WOMAD festivals. Other famous Qawwali singers include Fareed Ayaz & Abu Muhammad Duo, Abdullah Manzoor Niazi, Rahat Fateh Ali Khan, Badar Miandad, Rizwan-Muazzam Duo, Qutbi Brothers, the late Amjad Sabri, Qawwal Bahauddin Qutbuddin, Najm Saif and Brothers, Aziz Naza, among others. Out of these Fareed Ayaz & Abu Muhammad Duo, Abdullah Manzoor Niazi and Qawwal Bahauddin Qutbuddin and Najm Saif and Brothers, belong to the famed 'Qawwal Bachon ka Gharana' school of Qawwali, which was based in Delhi before 1947 and migrated to Pakistan after the Partition of British India.

The Mirpuri diaspora consists of Pahari people originating from the Mirpur District of Azad Kashmir, Pakistan, now living outside that district. Migration from Mirpur started occurring in the 1920s, when many Mirpuris left for Bombay to work on merchant ships.

During the partition of British India in 1947, many Mirpuri Hindus and Mirpuri Sikhs were forced to flee to cities in the princely state of Jammu and Kashmir to escape Muslim violence. The construction of the Mangla Dam by the Pakistani Government in the 1960s flooded fertile agricultural lands, forcing many Mirpuri Muslims to migrate to the United Kingdom to survive on work as labourers.

The State of Junagadh or Junagarh was a princely state located in Gujarat. It had been ruled by the Muslim Babi dynasty since 1654, first by Nawab of Junagadh within the Maratha Confederacy and later by British India. which, after the partition of British India, acceded to the Dominion of Pakistan. Subsequently, the Union of India annexed Junagadh in 1948, legitimized through a plebiscite held the same year. Pakistan claims sovereignty over the erstwhile princely state to this day.

Agha Muhammad Yahya Khan (4 February 1917 – 10 August 1980) was a Pakistani general who served as the third president of Pakistan from 1969 to 1971, under martial law. His presidency oversaw a civil war in East Pakistan, resulting in Bangladesh's secession. He also served as the fifth commander-in-chief of the Pakistan Army from 1966 to 1971.

A Pathan of Punjab, Khan was commissioned into the British Indian Army in 1939 and fought in the Second World War in the Mediterranean theatre. Following the Partition of British India, he joined the Pakistan Army and organized the Staff College, Quetta. In 1965, he played a vital role in executing Operation Grand Slam in Indian-administered Kashmir during the Second India–Pakistan War and was assigned to assume the army command in October 1966 by President Ayub Khan. In the wake of the 1968–1969 Pakistani protests, Ayub Khan resigned and transferred his authority to Yahya Khan.
