Punjab

Geography and Name

Punjab takes its name from the Persian panj āb, "five waters," referring to the Beas, Ravi, Sutlej, Chenab, and Jhelum rivers, the latter two now flowing through Pakistani Punjab. The Rigveda refers to the wider region as Sapta Sindhu, "land of the seven rivers," a count that included the Indus and the now largely dried-up Sarasvati. The alluvial plain fed by these rivers has made Punjab one of the most agriculturally productive regions of South Asia across every period of its history.

Ancient and Vedic Period

Punjab was a core region of the Indus Valley Civilization; Harappa, on the Ravi, was one of its two largest cities, flourishing from roughly 2600 to 1900 BCE with planned streets, standardized brick construction, and drainage systems. Following the civilization's decline, the region became a center of Vedic-era settlement, and much of the Rigveda's hymnody is traditionally associated with composition in this river landscape.

Classical and Early Medieval Empires

Punjab's location made it the subcontinent's principal gateway for invasion and exchange. Western Punjab formed part of the Achaemenid Persian Empire's Gandhara satrapy from the sixth century BCE. Alexander the Great crossed the region in 326 BCE, fighting the Battle of the Hydaspes against the local ruler Porus (Puru) before his troops refused to advance further east. The area subsequently passed to the Mauryan Empire under Chandragupta and Ashoka, then to a succession of Indo-Greek kingdoms — Menander I ruled from Sakala, present-day Sialkot — followed by Indo-Scythian, Kushan, and Gupta control, and later the Hindu Shahi dynasty, which held the northwest until the Ghaznavid conquest.

Turkic and Islamic Conquests

Mahmud of Ghazni captured Lahore in the early eleventh century, incorporating it as a provincial capital of the Ghaznavid empire and opening the region to sustained Turko-Persian political influence. Muhammad of Ghor's late-twelfth-century campaigns, including his defeat of Prithviraj Chauhan, extended this into the Delhi Sultanate era, under which Punjab remained a frontier province repeatedly raided by Mongol forces in the thirteenth and fourteenth centuries. Under the Mughals, Lahore grew into one of the empire's principal cities, serving at times as a favored imperial residence, notably under Akbar and Jahangir.

Sikhism and the Sikh Empire

Sikhism emerged in Punjab with Guru Nanak (1469-1539), born near Lahore, and developed over the teachings of nine successor Gurus. Guru Arjan Dev compiled the Adi Granth, the core of what became the Guru Granth Sahib, in 1604, and was executed by Mughal authorities under Jahangir in 1606. Guru Tegh Bahadur was similarly executed in Delhi under Aurangzeb in 1675. In 1699, Guru Gobind Singh founded the Khalsa, a disciplined order of initiated Sikhs, and shortly before his death in 1708 declared the Guru Granth Sahib the eternal Guru, ending the line of personal Gurus.

Sikh resistance to Mughal authority continued under Banda Singh Bahadur in the early eighteenth century. As Mughal central power weakened and Punjab endured repeated invasions by the Afghan ruler Ahmad Shah Durrani, Sikh warrior confederacies known as misls consolidated control of the region. Maharaja Ranjit Singh united these misls between 1799 and 1839, ruling from Lahore as a religiously plural, militarily modernized state — his Khalsa army employed European officers and artillery — that extended at its height to Peshawar and Kashmir.

Anglo-Sikh Wars and British Annexation

Ranjit Singh's death in 1839 was followed by a period of court instability. The First Anglo-Sikh War (1845-46) and Second Anglo-Sikh War (1848-49) ended in British victory, and the East India Company annexed Punjab in 1849 under Governor-General Dalhousie. The young Maharaja Duleep Singh was deposed and later exiled to Britain, and the Koh-i-Noor diamond, part of the Sikh treasury, was surrendered to the British crown as part of the annexation settlement.

Colonial Period and the Freedom Struggle

Under British rule, Punjab was developed as an agricultural and military resource: colonial engineers built extensive canal irrigation networks and rail lines, and the province became a major recruiting ground for the British Indian Army. It also became a center of resistance. On 13 April 1919, British troops under General Reginald Dyer fired on an unarmed crowd at Jallianwala Bagh in Amritsar, killing hundreds and galvanizing the independence movement nationally. Punjab produced prominent figures in that movement, including Bhagat Singh, executed in 1931 for his role in revolutionary activity against colonial rule; Lala Lajpat Rai, who died in 1928 from injuries sustained in a police charge during protests against the Simon Commission; and Udham Singh, who assassinated former Punjab lieutenant governor Michael O'Dwyer in London in 1940 in reprisal for Jallianwala Bagh.

Partition, 1947

India's 1947 independence brought Partition, with the Punjab boundary drawn by the Radcliffe Commission splitting the province between India and the new state of Pakistan. The division triggered one of the largest and most violent mass migrations of the twentieth century, as Hindus and Sikhs moved east and Muslims moved west amid widespread communal killing; estimates of the death toll across Partition vary widely and remain disputed among historians. West Punjab became part of Pakistan; East Punjab remained in India.

Reorganisation and the Punjabi Suba Movement

Indian Punjab initially retained a mixed Punjabi- and Hindi-speaking population spanning present-day Haryana and parts of Himachal Pradesh. The Akali Dal, led first by Master Tara Singh and later Sant Fateh Singh, campaigned for a linguistically defined Punjabi-speaking state, the Punjabi Suba movement. The Punjab Reorganisation Act of 1966 created the separate state of Haryana and transferred hill districts to Himachal Pradesh, leaving Chandigarh, designed by the architect Le Corbusier, as a shared union-territory capital for both Punjab and Haryana.

The Green Revolution and 1980s Insurgency

From the 1960s, Punjab became the epicenter of India's Green Revolution, adopting high-yield wheat varieties associated with agricultural scientists such as M. S. Swaminathan and Norman Borlaug alongside expanded irrigation and fertilizer use, cementing its identity as India's principal grain-surplus state. The following decade brought a militant Sikh separatist movement seeking an independent Khalistan, led in its most prominent phase by Jarnail Singh Bhindranwale. In June 1984, the Indian Army launched Operation Blue Star against militants who had fortified themselves inside the Golden Temple complex in Amritsar, causing significant casualties and damage to the shrine. Prime Minister Indira Gandhi was assassinated by her Sikh bodyguards in October 1984 in apparent retaliation, followed by anti-Sikh riots in Delhi and other cities. An insurgency in Punjab continued into the early 1990s before subsiding.

Culture and Economy

Punjab's cultural life centers on festivals tied to its agrarian calendar and Sikh heritage, including Baisakhi, Lohri, and the Gurpurabs marking the Sikh Gurus, alongside the Bhangra and Giddha dance traditions and a cuisine built around dishes such as sarson da saag and makki di roti. Its economy remains anchored in wheat and rice cultivation and dairy farming, supplemented by regional industries such as textile and bicycle manufacturing centered on Ludhiana, and handicraft traditions including Phulkari embroidery.
