The history of Punjab has witnessed the migration and settlement of different tribes of people with different cultures and ideas, forming a melting pot of Punjabi civilisation. The Indus Valley Civilization flourished in antiquity before recorded history until their decline around 1900 BCE. Punjab was enriched during the height of the Vedic period, but declined in predominance with the rise of the Mahajanapadas. The region formed the frontier of initial empires during antiquity including the Alexander's and Maurya empires. It was subsequently conquered by the Kushan Empire, Gupta Empire, and then Harsha's Empire. Punjab continued to be settled by nomadic people; including the Huna, Turkic and the Mongols. Circa 1000 CE, the Punjab came under the rule of Muslims and was part of the Delhi Sultanate, Mughal Empire, and Durrani Empire. Sikhism was founded in the 1500s and 1600s by the Sikh Gurus in the Punjab and resulted in the formation of the Sikh Confederacy after the fall of the Mughal Empire and ensuing conflict with the Durrani Empire. This confederacy was united into the Sikh Empire in 1801 by Maharaja Ranjit Singh.

The greater Punjab region was annexed by the British East India Company from the Sikh Empire in 1849. Following widespead religious violence in 1947, the Punjab Province of British India was divided along religious lines into West Punjab and East Punjab. The West Punjab became part of a Muslim-majority Pakistan, while the East Punjab became part of a Hindu-majority India. After the Punjabi Suba movement, the Indian Punjab and PEPSU were divided into three parts on the basis of language in 1966. Haryanvi and Hindi speaking areas (including various dialects) were carved out as Haryana, while the hilly regions and Pahari-speaking areas formed Himachal Pradesh, alongside the current state of Punjab. An insurgency occurred in Punjab during the 1980s. At present, the economy of Punjab is the 15th-largest state economy in India with ₹5.42 trillion (US$72 billion) in gross domestic product and a per capita GDP of ₹176,547 (US$2,300), ranking 17th amongst Indian states.
