The Punjab Province, officially the Province of the Punjab, was a province of British India, with its capital in Lahore and summer capitals in Murree and Simla. At its greatest extent, it stretched from the Khyber Pass to Delhi; and from the Babusar Pass and the borders of Tibet to the borders of Sind. Established in 1849 following Punjab's annexation, the province was partitioned in 1947 into West and East Punjab; and incorporated into Pakistan and India, respectively.
Most of the Punjab region was annexed by the East India Company on 29 March 1849 following the company's victory against the Sikh Empire's army at the battle of Gujrat in northern Punjab, a month prior. The Punjab was the last major region of the Indian subcontinent to fall to British imperialism.
