In Pakistan, no regional ethnic language has been granted official status at the national level, and as such Punjabi is not an official language at the national level, even though it is the most spoken language in Pakistan after Urdu, the national language of Pakistan. It is, however, the official provincial language of Punjab, Pakistan, the second largest and the most populous province of Pakistan as well as in Islamabad Capital Territory. The only two official national languages in Pakistan are Urdu and English, which are considered the lingua francas of Pakistan.The Majhi (ماجھی ਮਾਝੀ) dialect spoken around Amritsar and Lahore is Punjabi's prestige dialect.

History of Haryana
Hindi language movement of Punjab in the Hindi-speaking areas of Punjab started on 30 April 1957 and lasted till 27 December 1957, which paved the way for the demand for the formation of Haryana as a separate state for the Hindi speaking people of the united Punjab province. At the same time Punjab also had Punjabi suba & Punjabi language movement, under which Punjabi and gurmukhi were made official state language and script respectively, which was also made mandatory in schools of the whole of post-independence united Punjab. People of Hindi speaking areas of Punjab resisted this imposition. Punjab government retaliated by mass arrests and imprisonments, some of arrested activists were tortured in the prison. Sumer Singh of Naya Bans in Rohtak district gave his life for this cause during this movement.
